Today Laini and I explore our personal experiments with Intermittent Fasting or IF. Intermittent Fasting is a prolonged period of time during which you don't eat. There is much research into the impacts of IF and just yesterday CrossFit HQ shared a review of scientific research into the metabolic effects of IF. Here is a snipit of this research:
"The authors summarize the mechanisms by which restricted feeding may induce metabolic improvements. First, restricted feeding may impact circadian biology, supporting the natural variations in insulin secretion and sensitivity throughout the day (insulin sensitivity decreases throughout the day, and nighttime calorie consumption can drive greater elevations in HbA1c and diabetes risk over time). Second, even periodic fasts may impact the gut microbiome with downstream effects toward a variety of organ systems. Finally, intermittent fasting may improve lifestyle behavior by encouraging, for example, decreased energy intake or improved sleep"
Alternate-day fasting was the subject of little human research, though in mouse studies it was associated with reductions in obesity-related body weight, fasting insulin, fasting glucose, plasma cholesterol, and triglyceride levels.
