Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
The concept explains why dieting fails in most cases and results in a Yo-yo effect. [ 2 ] [ 3 ] A central element of the Summermatter cycle is that reductions in energy intake, occurring with dieting or starvation , initially successfully induce weight and adipose tissue loss. [ 1 ]
In humans, when calories are restricted because of war, famine, or diet, lost weight is typically regained quickly, including for obese patients. [2] In the Minnesota Starvation Experiment, after human subjects were fed a near-starvation diet for a period, losing 66% of their initial fat mass, and later allowed to eat freely, they reattained and even surpassed their original fat levels ...

Dieting is the practice of eating food in a regulated way to decrease, maintain, or increase body weight, or to prevent and treat diseases such as diabetes and obesity.As weight loss depends on calorie intake, different kinds of calorie-reduced diets, such as those emphasising particular macronutrients (low-fat, low-carbohydrate, etc.), have been shown to be no more effective than one another.
[10] [18] When used in routine care, there is evidence that VLCDs achieve average weight loss at 1 year around 10 kilograms (22 lb) [19] or about 4% more weight loss over the short term. [20] VLCDs can achieve higher short-term weight loss compared to other more modest or gradual calorie restricted diets , and the maintained long-term weight ...
