Weight loss relies primarily on a constant caloric deficit (CICO: Calories In, Calories Out), facilitated by a flexible and progressive approach rather than radical or punitive dietary restriction.

noli's read

The principle of caloric deficit is solidly supported by research (meta-analyses on energy balance), confirming that it constitutes the fundamental lever for weight management. The community correctly emphasizes that rapid initial weight loss is often linked to water weight variation (observational evidence in nutrition), a phenomenon well documented during the reduction of salt and carbohydrate intake. The idea of prioritizing dietary flexibility (not completely banning certain foods) is supported by studies on adherence, suggesting that a rigid approach more often leads to abandonment. The assertion regarding the '3-week' period to change habits is a popular simplification of behavioral conditioning, although the science of habits shows much broader individual variability (studies on automaticity). Finally, the encouragement of progressive physical activity is validated by literature on injury prevention. The community strongly converges toward pragmatic and moderate support.
