what it claims

Gradually adjust your energy intake up or down over the course of a program to compensate for metabolic variations linked to weight changes.

The idea of adjusting portion sizes as one's physique evolves is based on very solid physiological foundations. Long-term observational studies, such as the work conducted by Christian Weyer's team, confirm that body weight variations directly alter our total daily energy expenditure. Furthermore, literature reviews, such as that by Müller et al. (2016), describe in detail how the body adapts its metabolism to conserve energy during weight loss. Longitudinal clinical studies, particularly those conducted by researcher Cátia Martins, show that weight loss is accompanied by a reduction in energy consumption that may even go slightly beyond the simple loss of mass. Regularly recalibrating intake is therefore a highly consistent strategy for avoiding weight-loss plateaus and continuing to progress. This gradual, body-attuned approach is widely validated by current science.

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.
