The mechanism of action is beyond the scope of this study, but the reduction may be due to increased LDL receptor activity, potentially from cholesterol-deficient hepatocytes resulting from the fast 39,40 that did not occur until feeding resumed. Clinical observation and indirect measures of protein catabolism (e.g., urea excretion) indicate that muscle loss is minimal 30,31, suggesting that the lean mass loss is primarily from fluids. However, there have been few human studies on the post-fast refeeding period and knowledge is limited.

Weight and Body Composition Autophagy is linked to improved cellular health and longevity, making it an essential factor in fasting. This process, which is activated during fasting, allows the body to break down and recycle damaged cellular components, ultimately enhancing metabolic efficiency. Conversely, levels of growth hormone can increase, which aids in fat loss and muscle preservation. This is a natural response as the body attempts to conserve energy in the absence of food. A metabolically healthy control population is necessary to determine if the observed effects, especially on post-fast glucose and insulin levels, are a transient response to fasting or specific to metabolic dysfunction. Indeed, prolonged fasting may result in temporary physiological changes, such as downregulation of insulin receptor expression , elevated VLDL and TG levels 16,46, and metabolic inflammation in adipose tissue , which could temporarily affect insulin sensitivity during refeeding. Each phase lasted 1 day per 7–10 days of water-only fasting for a total of at least half of the fasting length. Reported health benefits may be because even brief periods of fasting (e.g., overnight) reduce glucose levels sufficiently to increase the production of ketone bodies 5,6.

Men are more likely to accumulate fat in the abdominal region, whereas women have a higher tendency to deposit fat subcutaneously on their lower extremities.34 In view of this, we were interested in seeing if changes in waist circumference varied by biological sex. This technique is considered an accurate and reproducible measure of abdominal fat, when compared with MRI.33 Measuring waist circumference serves as a less expensive and more accessible tool for measuring visceral fat mass. This will help inform whether these marked reductions in lean mass are maintained weeks or months after the fast is completed. Higher emotional intelligence and lower impulsivity correlated with greater fat loss, while neuroticism and tension correlated with more lean mass (LBM) loss. Blood glucose, insulin, and leptin levels dropped significantly, and ketone bodies increased fivefold. Capillary blood glucose and ketone levels were also monitored. Participants had a stable body weight, were not taking medications that alter metabolism, and did not have major chronic illnesses. Adiponectin plays a key role in energy regulation by activating adenosine monophosphate-activated protein kinase (AMPK), which boosts glucose uptake and fatty acid oxidation.

However, data on the effects of fasting on cardiometabolic markers, including insulin sensitivity, during the post-fast refeeding period are sparse . We previously reported that this fasting method, including the gradual re-introduction of exclusively whole-plant foods without added salt, oil, or sugar, is tolerable with a low risk of causing a serious adverse event . Intermittent fasting and prolonged very-low-calorie fasting methods have emerged as potential treatments for obesity and cardiometabolic dysfunction . Participants were recruited from patients who had voluntarily elected to complete a water-only fast in order to improve their overall health according to an established protocol at an independent, residential medical center.
