My boyfriend was doing intermittent fasting IF , and I'll admit I was skeptical of it. It wasn't hugely popular at the time, and there were a lot of naysayers insisting it wasn't healthy to fast. But after reading an article by entrepreneur Sumaya Kazi, where she talked about losing 50 pounds through IF, I decided to go for it.

Within five months I was down 50 pounds, and within a year I had lost 98 pounds, and I just kept going. There were a number of different methods of intermittent fasting, but I threw caution to the wind and opted for alternate-day fasting ADF , which means I would only eat every other day, which I know can sound scary.

To begin with, I allowed myself up to calories on my fasting days to help me ease into it. After the first week, I was able to go every other day, or 38 to 40 hours, without eating. I made sure I learned how to calculate calories and would eat between my basal metabolic rate — how many calories my body needs at rest — and my total daily energy expenditure, or how many calories I actually burned in a given day.

I began my ADF journey on September 5, , and one month later I was down 16 pounds. Now I normally fluctuate between and pounds. Keep in mind that alternate-day fasting and intermittent fasting is not for everyone.

It may not be a sustainable diet plan for people with underlying health conditions, like type 1 diabetes, or if you're pregnant. It can also trigger disordered eating tendencies in those with a history of eating disorders.

Talk to your doctor before trying a diet plan like alternate-day fasting, to see if it's suitable for you and your health needs. People always ask me what I eat on my "eat days," as perhaps they think I gorge. But I'm actually much more mindful about what I put in my body now.

I like the salad because it adds lots of nutrients and fiber to keep me full. It's full of protein and probiotics and gives me the energy I need before I workout for the day. I never seem to make the same thing twice.

But I do like making a lot of healthy chicken recipes , which I'll come up with myself or search for inspiration on Pinterest. If I feel I need to modify anything to make it healthier, then I do so.

The best thing with fasting is that as long as it fits within your calorie range, you can have it! I never count macros or limit myself. I think I assumed that the most difficult thing would be getting through the days when I didn't eat anything.

I went from eating around 2, calories a day to fewer than 2, every other day, so it was a huge change. But because I was so determined to change, somehow that wasn't the hardest part.

I started adding physical activity about six months into my weight-loss journey. I would run on the days I wasn't fasting. When I had dropped 85 pounds, I began lifting weights, too. When I began, it was something I just could not enjoy. I found it hard to lift and felt like I wasn't making progress.

I couldn't see the calories I was burning, unlike when I was on a treadmill. As I pushed myself to continue and get more into it, though, the physical difference was apparent and I was hooked! Now that I have gotten down to a healthy weight, I work out six days a week , lifting weights on my fasting days and running on my eat days.

I would have to say my results are what helped me to keep going. Every month I was losing weight and getting stronger and feeling healthier. I loved that feeling of seeing actual results for once when I struggled with it for so long before. It's what continued to push me forward and lead me to where I am today.

It takes time and patience. I took regular photos of myself, too, so I could have a record of before and after. When you see yourself in the mirror every day, it's difficult to see those changes.

Even though everyone was telling me how well I was doing and how great I looked, it was hard to believe. It probably wasn't until I got down to a size 10 that I realized just how much of a transformation I had made. You have to go into this with percent dedication. It's not easy — it's hard, and you will struggle on some days.

If you don't give it your all, you won't stick with this method very long. It takes all of your willpower and motivation to stay with such a strict routine and schedule. You can't go into it thinking, "This might work for me" and then give up after a couple days just because you aren't seeing results.

I suggest you only weigh yourself once a month to keep from getting discouraged. ADF indicates alternate-day fasting; DCR, daily calorie restriction. eFigure 2. Mean Energy Restriction by Diet Group at Month 6 Measured by Doubly Labeled Water.

Trepanowski JF , Kroeger CM , Barnosky A, et al. Effect of Alternate-Day Fasting on Weight Loss, Weight Maintenance, and Cardioprotection Among Metabolically Healthy Obese Adults : A Randomized Clinical Trial.

JAMA Intern Med. Question Is alternate-day fasting more effective for weight loss and weight maintenance compared with daily calorie restriction? Findings This randomized clinical trial included metabolically healthy obese adults. Weight loss after 1 year in the alternate-day fasting group 6.

Meaning Alternate-day fasting does not produce superior weight loss or weight maintenance compared with daily calorie restriction. Importance Alternate-day fasting has become increasingly popular, yet, to date, no long-term randomized clinical trials have evaluated its efficacy.

Objective To compare the effects of alternate-day fasting vs daily calorie restriction on weight loss, weight maintenance, and risk indicators for cardiovascular disease. Design, Setting, and Participants A single-center randomized clinical trial of obese adults 18 to 64 years of age; mean body mass index, 34 was conducted between October 1, , and January 15, , at an academic institution in Chicago, Illinois.

The trial involved a 6-month weight-loss phase followed by a 6-month weight-maintenance phase. Main Outcomes and Measures The primary outcome was change in body weight. Secondary outcomes were adherence to the dietary intervention and risk indicators for cardiovascular disease.

Mean weight loss was similar for participants in the alternate-day fasting group and those in the daily calorie restriction group at month 6 —6. Participants in the alternate-day fasting group ate more than prescribed on fast days, and less than prescribed on feast days, while those in the daily calorie restriction group generally met their prescribed energy goals.

There were no significant differences between the intervention groups in blood pressure, heart rate, triglycerides, fasting glucose, fasting insulin, insulin resistance, C-reactive protein, or homocysteine concentrations at month 6 or Mean high-density lipoprotein cholesterol levels at month 6 significantly increased among the participants in the alternate-day fasting group 6.

Mean low-density lipoprotein cholesterol levels were significantly elevated by month 12 among the participants in the alternate-day fasting group Conclusions and Relevance Alternate-day fasting did not produce superior adherence, weight loss, weight maintenance, or cardioprotection vs daily calorie restriction.

Trial Registration clinicaltrials. gov Identifier: NCT The first-line therapy prescribed to obese patients for weight loss is daily calorie restriction.

Alternate-day fasting regimens have increased in popularity during the past decade, and several best-selling diet books 14 , 15 have promoted this approach.

More than 1 million copies of these books have been sold in the United States and United Kingdom to date. Despite the growing popularity of alternate-day fasting, to our knowledge, no long-term randomized clinical trials have evaluated its efficacy or compared this regimen with a conventional weight-loss diet.

We conducted a 1-year, randomized clinical trial to compare the effects of alternate-day fasting vs daily calorie restriction on body weight and risk indicators for cardiovascular disease.

We hypothesized that the participants in the alternate-day fasting group would be more adherent to their diet, achieve greater weight loss, and experience more pronounced improvements in risk indicators for cardiovascular disease during the 6-month weight-loss phase compared with those in the daily calorie restriction group.

We also hypothesized that the alternate-day fasting group would better maintain their weight loss and sustain their improvements in risk indicators for cardiovascular disease during the 6-month weight-maintenance phase compared with the daily calorie restriction group.

We conducted the trial between October 1, , and January 15, , at the University of Illinois at Chicago. Participants were recruited from the Chicago area by means of flyers placed around the university and were screened via a questionnaire, an assessment of body mass index, and a pregnancy test.

Individuals included were men and women between 18 and 65 years of age, with a body mass index between The protocol was approved by the Office for the Protection of Research Subjects at the University of Illinois at Chicago, and written informed consent was obtained from all participants.

The full protocol is available in Supplement 1. Participants were randomized in a ratio to an alternate-day fasting group, daily calorie restriction group, or no-intervention control group. Randomization was performed by a stratified random sampling procedure by sex, age years and years , and body mass index Block size ranged from 1 to 11 participants.

The active trial duration was 1 year and consisted of a baseline phase 1 month , a weight-loss phase 6 months , and a weight-maintenance phase 6 months eFigure 1 in Supplement 2. We chose this design because weight loss typically peaks at 6 months during a lifestyle intervention.

Baseline total energy expenditure was measured using doubly labeled water. Participants in the alternate-day fasting group and those in the daily calorie restriction group were provided with all meals during the first 3 months of the trial and received dietary counseling thereafter eFigure 1 in Supplement 2.

From months 4 to 6, when food was no longer provided, intervention participants met individually with a dietician or nutritionist weekly to learn how to continue with their diets on their own.

At the beginning of the 6-month weight-maintenance phase, total daily energy expenditure was reassessed using doubly labeled water. Intervention participants met with the dietician individually each month to learn cognitive behavioral strategies to prevent weight regain 19 and received personalized energy targets for weight maintenance based on results from doubly labeled water.

Participants in the control group were instructed to maintain their weight throughout the trial and not to change their eating or physical activity habits. Controls received no food or dietary counseling but visited the research center at the same frequency as the intervention participants to provide outcome measurements.

Controls who completed the month trial received 3 months of free weight-loss counseling and a month gym membership at the end of the study.

The primary outcome of the study was change in body weight, which was measured monthly via a digital scale while the participant was in a hospital gown.

Fat mass and lean mass were measured every 6 months in the fasted state by dual-energy x-ray absorptiometry QDR W; Hologic. Visceral fat mass was measured every 6 months by magnetic resonance imaging performed with a 1.

Mean percentage energy restriction during the weight-loss phase was retrospectively calculated by the intake balance method using doubly labeled water and changes in body composition. Intervention participants were considered to be adherent when their actual energy intake, determined via food records, was within kcal of their prescribed daily energy goal.

Blood samples were obtained following a hour fast every 6 months collected on the morning after a feast day for the alternate-day fasting group.

Secondary outcomes included blood pressure, heart rate, and total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, fasting glucose, fasting insulin, C-reactive protein, and homocysteine concentrations analytical methods are detailed in the full protocol in Supplement 1.

Thus, we initially aimed to recruit 90 participants 30 per group , assuming that 78 participants 26 per group would complete the trial. We later decided to recruit participants to increase our statistical power because our dropout rate was higher than expected.

Tests for normality were included in the model, and all data were found to be normally distributed. We conducted an intention-to-treat analysis, which included data from all participants who underwent randomization.

Results are reported by intention-to-treat analysis unless indicated otherwise. This model provides unbiased estimates of time and treatment effects under a missing-at-random assumption.

Time was not assumed to be linear in the model. This strategy allowed for estimation of time and diet effects and their interaction without imposing a linear time trend. The analyses were performed using SAS, version 9.

Of the participants who were screened, More participants in the alternate-day fasting group than in the daily calorie restriction group withdrew owing to difficulties adhering with the diet. All baseline characteristics had comparable distributions between the alternate-day fasting group, the daily calorie restriction group, and the control group Table 1.

The participants were primarily metabolically healthy obese women. On the fast day Figure 2 A , participants in the alternate-day fasting group exceeded their prescribed energy goal at months 3 and 6.

On the feast day Figure 2 B , participants in the alternate-day fasting group ate less than their prescribed goal at months 3, 6, 9, and Participants in the daily calorie restriction group Figure 2 C met their prescribed energy goals at months 3, 6, and 12 but ate less than their prescribed goal at month 9.

A higher proportion of participants in the daily calorie restriction group were adherent to their energy goals at months 3, 6, 9, and 12 relative to those in the alternate-day fasting group. Data on dietary intake are displayed in eTable 1 in Supplement 2.

Percentage of energy intake from fat, carbohydrates, and protein did not differ significantly over time in any of the groups. Physical activity, measured as steps per day, did not change during the course of the trial in any group eTable 2 in Supplement 2.

This level of activity is approximately to steps per day higher than that of the average overweight or obese adult. Changes in body weight are displayed in Figure 3 and Table 2.

Weight loss was not significantly different between the alternate-day fasting group and the daily calorie restriction group at month 6.

At the end of the study, total weight loss was —6. Weight regain from months 6 to 12 —0. Moreover, weight regain from months 6 to 12 was not significantly different between the alternate-day fasting group and controls 0. Changes in body composition are reported in Table 2. There were no statistically significant differences between the alternate-day fasting group and the daily calorie restriction group for fat mass, lean mass, or visceral fat mass at month 6 or month Blood pressure was not significantly different between the intervention groups, or relative to controls, at month 6 or month 12 Table 2.

There were also no statistically significant differences in heart rate between the alternate-day fasting group and the daily calorie restriction group at month 6 or month 12 Table 2. Changes in plasma lipids during the course of the trial are shown in Table 2. Total cholesterol levels were not significantly different between the intervention groups, or relative to controls, at month 6 or month At month 6, high-density lipoprotein cholesterol levels were significantly elevated in the alternate-day fasting group by 6.

Low-density lipoprotein cholesterol concentrations did not differ significantly between the intervention groups at month 6.

At month 12, low-density lipoprotein cholesterol levels significantly increased in the alternate-day fasting group Triglyceride levels did not differ significantly between the intervention groups at month 6 or month Changes in glucoregulatory and inflammatory factors are displayed in Table 2.

Fasting plasma glucose did not differ significantly between the intervention groups, or relative to controls, at month 6 or month There were also no significant differences in fasting insulin or the homeostasis model assessment of insulin resistance between the intervention groups at month 6 or month High-sensitivity C-reactive protein and homocysteine levels did not differ significantly between the intervention groups, or relative to controls, at month 6 or month The results of this randomized clinical trial demonstrated that alternate-day fasting did not produce superior adherence, weight loss, weight maintenance, or improvement in risk indicators for cardiovascular disease compared with daily calorie restriction.

Alternate-day fasting has been promoted as a potentially superior alternative to daily calorie restriction under the assumption that it is easier to restrict calories every other day. However, our data from food records, doubly labeled water, and regular weigh-ins indicate that this assumption is not the case.

Rather, it appears as though many participants in the alternate-day fasting group converted their diet into de facto calorie restriction as the trial progressed.

It was also shown that more participants in the alternate-day fasting group withdrew owing to dissatisfaction with diet compared with those in the daily calorie restriction group Figure 1. Taken together, these findings suggest that alternate-day fasting may be less sustainable in the long term, compared with daily calorie restriction, for most obese individuals.

Nevertheless, it is still possible that a certain smaller segment of obese individuals may prefer this pattern of energy restriction instead of daily restriction. It will be of interest to examine what behavioral traits eg, ability to go for long periods without eating make alternate-day fasting more tolerable for some individuals than others.

To our knowledge, the present study is the longest and largest trial of alternate-day fasting to date. Food was provided to the intervention participants during the first 3 months of the weight-loss phase to promote adherence 26 and show participants the types and quantities of foods that they should be eating.

This finding suggests that limiting caloric intake to approximately kcal every other day may have been difficult for many participants early in the intervention. For instance, measuring changes in subjective appetite hunger and fullness in conjunction with modulations in appetite hormones ghrelin, peptide YY, and glucagon-like peptide-1 could offer some insight into why daily calorie restriction may allow for easier adherence compared with alternate-day fasting.

Contrary to our original hypotheses, the participants in the alternate-day fasting group did not experience more pronounced improvements in risk indicators for cardiovascular disease compared with the participants in the daily calorie restriction group.

However, the trial included primarily metabolically healthy obese adults. Since many of the participants had normal cholesterol levels and normal blood pressure at baseline, it is not surprising that most risk indicators for cardiovascular disease did not change in response to diet.

Our study has several limitations. First, the duration of the maintenance phase was short 6 months. Second, the control group was imperfect, in that they received no food, no counseling, and less attention from study personnel, relative to the intervention groups, which may have confounded our findings.

We also failed to include the control group in our initial power calculation. The higher dropout rate in the alternate-day fasting group may have also introduced a possible selection bias between groups. The alternate-day fasting diet was not superior to the daily calorie restriction diet with regard to adherence, weight loss, weight maintenance, or improvement in risk indicators for cardiovascular disease.

These findings suggest that ADF is effective for weight loss and cardio-protection in normal weight and overweight adults, though further research implementing larger sample sizes is required before solid conclusion can be reached. Peer Review reports. Intermittent fasting regimens, particularly alternate day fasting ADF protocols, have gained considerable popularity in the past decade.

Only a handful of studies have been performed to test the effects of ADF on body weight and coronary heart disease CHD risk reduction, and almost all of these studies have been undertaken in obese populations BMI 30— These reports also suggest that ADF may aid in the retention of lean mass in obese individuals [ 2 — 4 ].

In addition to these favorable body composition changes, improvements in CHD risk have also been noted. Beneficial changes in blood pressure and adipokine profile i.

increases in adiponectin, and decreases in leptin and resistin have also been reported [ 2 — 4 ]. Taken together, this preliminary work suggests that ADF may be effective for weight loss and CHD risk reduction in obese adults.

An important question that remains unresolved is whether the favorable effects of ADF can also be observed in normal weight and overweight populations.

Only two human studies [ 5 , 6 ] have tested the effect of ADF on body weight and CHD risk in non-obese subjects. In a study by Heilbronn et al. Contrary to these findings, Halberg et al. While these trials [ 5 , 6 ] lay some groundwork, they are limited by their short durations 2—3 weeks and their lack of a control group.

As such, a longer-term trial 12 weeks that employs a control group is well warranted. Accordingly, the present study examined the effect of ADF on body weight, body composition, and CHD risk parameters in both normal weight and overweight adults in a week randomized controlled feeding trial.

We hypothesized that ADF would reduce body weight and CHD risk in normal weight and overweight participants, when compared to controls. Subjects were recruited from the Chicago area by means of advertisements placed around the University of Illinois, Chicago campus.

A total of individuals expressed interest in the study, but only 32 were recruited to participate after screening via a preliminary questionnaire and BMI assessment Figure 1. Inclusion criteria were as follows: BMI between 20 and The experimental protocol was approved by the University of Illinois, Chicago, Office for the Protection of Research Subjects, and all research participants gave their written informed consent to participate in the trial.

The research protocol was in compliance with the Helsinki Declaration. A week, randomized, controlled, parallel-arm feeding trial was implemented as a means of testing the study objectives.

Subjects were randomized by KAV by way of a stratified random sample. Energy needs for each subject were determined by the Mifflin equation [ 7 ]. The feed and fast days began at midnight each day, and all fast day meals were consumed between ADF subjects were provided with meals on each fast day ranging from — kcal , and ate ad libitum at home on the feed day.

All ADF fast day meals were prepared in the metabolic kitchen of the Human Nutrition Research Center HNRU at the University of Illinois, Chicago. All meals were consumed outside of the research center. ADF subjects were permitted to consume energy-free beverages, tea, coffee, and sugar-free gum, and were encouraged to drink plenty of water.

Control subjects were permitted to eat ad libitum every day, and were not provided with meals from the research center. Twelve-hour fasting blood samples were collected between 6.

Participants were instructed to avoid exercise, alcohol, and coffee for 24 h before each visit. During the week diet intervention, subjects in the ADF group were instructed to eat only the foods provided on each fast day. To assess energy intake on the fast days, ADF subjects were asked to report any extra food items consumed i.

Additionally, subjects were instructed to return any leftover food items to the HNRU for weighing. To assess energy intake on the feed days, ADF and control subjects were asked to complete a 3-day food record on 2 feed days during the week, and on 1 feed day during the weekend, at week 1 and At baseline, the Research Dietician provided 15 min of instruction to all participants on how to complete the food records.

These instructions included verbal information and detailed reference guides on how to estimate portion sizes and record food items in sufficient detail to obtain an accurate estimate of dietary intake. A validated visual analog scale VAS was used to measure hunger, fullness, and satisfaction with the ADF diet [ 9 ].

The scale was completed on 3 fast days before bedtime at week 1 and In brief, the VAS consisted of mm lines, and subjects were asked to make a vertical mark across the line corresponding to their feelings from 0 not at all to extremely for hunger, satisfaction, or fullness.

Quantification was performed by measuring the distance from the left end of the line to the vertical mark. Body weight was assessed to the nearest 0. Body composition fat mass and fat free mass was measured using dual x-ray absorptiometry DXA Hologic QDR W, Hologic Inc.

Plasma total cholesterol, HDL-cholesterol, and triacylglycerol concentrations were measured in duplicate using enzymatic kits Biovision Inc. The concentration of LDL-cholesterol was calculated using the Friedewald, Levy and Fredrickson equation. LDL particle size was measured by linear polyacrylamide gel electrophoresis Quantimetrix Lipoprint System, Redondo Beach, CA, USA at week 1 and 12 [ 10 , 11 ].

Briefly, 25 μL of sample was mixed with μL of liquid loading gel containing Sudan black, and added to the gel tubes. The intra-assay coefficients of variation CV for total cholesterol, HDL cholesterol, triacylglycerol, and LDL particle size were 3.

All measurements were taken at week 1 and Blood pressure was measured in triplicate with the subject in a seated position after a min rest.

C-reactive protein CRP was measured in duplicate using Immulite High Sensitivity CRP kits Diagnostic Products Corporation, Los Angeles, CA. Plasma homocysteine measurements were carried out in duplicate using HPLC with fluorometric detection.

The intra-assay coefficients of variation CV for CRP, homocysteine, adiponectin, leptin, and resistin were 5. Results are presented as means ± standard error of the mean SEM. Tests for normality were included in the model. No variables were found to be not normal. Differences between groups at baseline were tested by independent samples t -test.

Within-group changes from week 1 to 12 were tested by a paired t -test. Between-group differences were tested by an independent samples t -test. Data were analyzed by using SPSS software version Thirty-two subjects commenced the study, with 30 completing the entire week trial Figure 1. Baseline characteristics of the subjects who completed the trial are presented in Table 1.

There were no significant differences at the beginning of the study between groups for age, sex, ethnicity, body weight, body composition, height or BMI. Energy intake, hunger, satisfaction, and fullness are reported in Table 2.

At baseline, there were no differences between the ADF and control groups for feed day energy intake. From week 1 to 12 of the study, energy intake remained constant on both feed and fast days in the ADF group.

Hunger levels were moderate as baseline, and did not change by week 12 in either group. Changes in body weight and body composition are displayed in Figure 2. Body weight and body composition changes at week Values reported as mean ± SEM.

ADF: Alternate day fasting. No difference between groups for fat free mass at week 12 Independent samples t -test. Changes in plasma lipids and LDL particle size are reported in Table 3.

However, changes in total cholesterol levels were not significantly different from controls at week HDL cholesterol concentrations remained unchanged throughout the trial. Changes in blood pressure, homocysteine, CRP, and adipokines are shown in Table 4. Plasma homocysteine and resistin concentrations remained unchanged after 12 weeks of treatment.

This diet strategy may also have cardio-protective effects in non-obese subjects, by way of lowering triacylglycerols, CRP and leptin, while increasing LDL particle size and adiponectin concentrations.

The primary goal of this study was to determine if non-obese individuals could benefit from ADF in terms of weight loss. Previous ADF studies implementing non-obese subjects report inconsistent findings [ 5 , 6 ]. The limited amount of weight loss reported previously is undoubtedly a factor of the short trial durations implemented [ 5 , 6 ].

Thus, we wanted to determine if the degree of weight loss could be amplified if the trial duration was extended to 12 weeks.

This degree of weight loss in non-obese participants is similar to what has been reported for obese individuals undergoing ADF [ 2 — 4 ]. For instance, Bhutani et al. In line with these findings, Klempel et al.

Thus, ADF may produce a mean rate of weight loss of approximately 0. Fat free mass was also retained after 12 weeks of ADF in non-obese individuals. This finding is similar to what has been reported in previous short-term studies of ADF [ 2 — 4 ].

As such, the beneficial preservation of fat free mass observed in obese individuals [ 2 — 4 ] may be replicated in non-obese subjects participating in ADF protocols.

Our findings also indicate that normal weight and overweight subjects have no problem adhering to the fast day protocol for 12 weeks. It should be noted, however, that one normal weight subject dropped out of the trial due to an inability to adhere to the diet.

Complementary to previous reports [ 12 , 13 ], there was very little or no hyperphagic response on the feed day in response to the lack of food on the fast day.

This lack of hyperphagia allowed for overall energy restriction to remain high throughout the study, and undoubtedly contributed to the sizeable degree of weight loss observed here.

As for eating behaviors, perceived hunger was moderate at baseline and did not change by week This is contrary to findings in obese participants, which consistently show declines in hunger after 8—12 weeks of ADF [ 11 , 12 ]. Dietary satisfaction and feelings of fullness, on the other hand, increased from baseline to post-treatment.

These increases in satisfaction and fullness have also been noted in obese subjects [ 11 , 12 ], and may play a role in long-term adherence to the diet. The cardio-protective effects of ADF were also examined. LDL particle size also increased post-treatment 4 Å from baseline. These changes in lipid risk factors are in line with what has been reported for obese ADF subjects [ 14 , 15 ].

Thus, ADF may improve plasma lipids to the same extent in non-obese subjects as it does in obese subjects. Additional vascular benefits, including decreases in circulating leptin and CRP concentrations, in conjunction with increases in adiponectin, were also noted in non-obese subjects undergoing ADF.

As for HDL cholesterol, homocysteine, and resistin concentrations, no effect was observed. It will be of interest in future studies to determine how alterations in macronutrient intake on the fast day may affect weight loss and cardiovascular outcomes. For instance, it has been well established that Mediterranean [ 19 ] and certain low-carbohydrate diets [ 20 ] help to maintain a healthy body weight and reduce CHD risk.

Whether further reductions in body weight and CHD risk would occur if ADF were combined with Mediterranean or low-carbohydrate diets, undoubtedly warrants investigation. A couple of adverse events were reported during the study.

Two subjects experienced mild headaches during week 1 of the trial, which may or may not be related to dietary treatment. One other subject reported constipation during week 1 and 2 of the trial. The subject was advised to consume more fruits and vegetables on feed days, and the constipation subsided by week 3 of the dietary intervention period.

This study has several limitations. First and foremost, it must be acknowledged that this pilot study was originally designed to compare the effects of ADF in normal weight versus overweight individuals on body weight and CHD risk.

In view of this, we decided to combine the normal weight and overweight groups into one group to increase sample size. This post hoc change should be taken into consideration when interpreting the findings of this paper.

Secondly, physical activity was not assessed throughout the trial, thus the degree of weight loss associated with increased energy expenditure from exercise is not known.
