A 2019 review of weight-change interventions, including alternate day fasting, time-restricted feeding, exercise and overeating, found that body weight homeostasis could not precisely correct "energetic errors" – the loss or gain of calories – in the short-term. [72]

Acesso em 30 dez 2021 Intermittent fasting, or "skip-a-day" feeding, is supposedly the most common feeding strategy for poultry in broiler breeder farms worldwide, as an alternative to adding bulky fibers to the diet to reduce growth. It is perceived as welfare-reducing and thus illegal in several European countries including Sweden. Intermittent fasting in poultry appears to increase food consumption but reduce appetitive behaviors such as foraging.

Ele recorre tanto ao glicogênio, uma forma de energia armazenada nos músculos, quanto ao tecido adiposo, e neste momento ativa hormônios que atuam na quebra de gordura (lipólise), como o glucagon.

Quando jejuamos, obrigamos o corpo a usar as reservas de gordura como fonte de energia, em vez dos açúcares, como acontece quando comemos. Além disso, ao restringir os períodos em que podemos comer, temos tendência para ingerir menos calorias por dia.

A news item in the Canadian Medical Association Journal expressed concern that promotional material for the 5:2 diet showed people eating high-calorie food, such as hamburgers and chips, and that this could encourage binge eating since the implication was that "if you fast two days a week, you can devour as much junk as your gullet can swallow during the remaining five days". [103] Binge eating following dietary restrictions has been observed in a post-war famine study, where nineteen prisoners of war were observed during their rehabilitation with unlimited access to food, and found they tended to engage in binge eating.
