This advice is based on the concept of 'adaptive thermogenesis' or 'diet breaks.' Studies, such as the MATADOR trial published in the International Journal of Obesity (RCT), suggest that taking breaks from a caloric deficit can help mitigate metabolic adaptation—the decrease in energy expenditure that the body triggers to preserve its reserves. In terms of evidence, these clinical trials show encouraging results for long-term weight management and the reduction of diet-related fatigue. The idea of an 'equivalent duration' is a pragmatic approach for stabilizing hormonal hunger and satiety signals. It is not a universal biological rule set in stone, but an effective behavioral strategy to avoid the yo-yo effect. Current data strongly support the idea that maintenance phases are crucial for the sustainability of change.

What the graded evidence says

Evidence: B

Effect: ad libitum energy intake as a function of dietary energy density — lowering dietary energy density consistently reduces spontaneous calorie intake at matched food weight/fullness; body-fat change tracks the resulting energy balance
Measured on: general adults

Energy balance is the driver, but it's affected by many things (satiety, food quality, sleep, activity), so it's not about rigid calorie math. 'Fat-burning' or 'negative-calorie' foods are a myth.

Other advice in the Register that leans on the same research.

To lose weight, there are no shortcuts such as fat-burning foods, organic products, or targeted exercises; everything relies on a caloric deficit, overall physical activity, and the total quantity of food consumed.

holds upGraeme Tomlinson

To lose weight without starving yourself, you should prioritize foods with low caloric density but high volume (such as vegetables), because the physical volume of ingested food does not always correspond to its calorie content.

holds upGraeme Tomlinson

"Fat fasting" (fasting based solely on the ingestion of fats) within a carnivore diet is an ineffective method for fat loss, as it often leads to a massive caloric surplus and lacks essential fiber.
