- Brief Summary
The purpose of this study is to assess the effects of repeated periods of modified fasting in support of healthy weight management and prevention of weight gain over the winter holiday period (mid-November to early January) in comparison to regular diet and activity.
- Detailed Description
This study is a randomized, placebo-controlled trial in which subjects assigned to the modified fasting cohort will undergo consecutive weekly cycles of modified fasting for two consecutive days.
The primary objective is to assess the effects of repeated periods of modified fasting on body weight.
The secondary objectives include assessment of the effects of modified fasting on percent body fat, waist circumference and fasting levels of hs-CRP (hs-C-reactive protein), IL-6 (Interleukin-6), IL-8 (interleukin-8), IL-12 (interleukin-12), TNF-a (tumor necrosis factor-alpha), IGF-1 (insulin-like growth factor 1), IGFBP-1 (insulin-like growth factor-binding protein 1) , Total Cholesterol, LDL cholesterol, HDL cholesterol, Glucose, Triglyceride, Insulin, Vitamin-D, 25-Hydroxy,
Participants will undergo assessments of blood tests, vital signs, BMI, body weight, waist circumference and percent body fat.
