Current site Current page. 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.

Thus, this study may not be adequately powered to detect changes in certain CHD risk parameters e. Thus, our findings for the hyperphagic response on the feed day may be inaccurate.

In summary, these preliminary findings suggest that ADF is a viable weight loss strategy for normal weight and overweight individuals wishing to lose a moderate amount of weight 5—6 kg within a relatively short period of time 12 weeks.

This diet may also help lower CHD risk in non-obese individuals, though further investigation is warranted to confirm these effects. It should also be noted that the purpose of this paper is to report pilot feasibility findings.

It is our hope that this preliminary data will be utilized to design larger-scale longer-term trials with similar objectives, in normal weight and overweight participants undergoing ADF.
