Carbohydrates are not inherently fattening, and insulin is not solely responsible for weight gain; the key lies in a caloric deficit, regardless of the type of diet (keto or moderate).

Abbey Sharp's advice aligns well with the current scientific consensus in nutrition. It is established that weight gain results from a positive energy balance over the long term, rather than the isolated consumption of a single macronutrient (meta-analysis, Journal of the International Society of Sports Nutrition). The idea that insulin is the sole driver of fat storage is an oversimplification; it participates in metabolism, but storage depends primarily on total caloric intake (RCT, JAMA). For individuals with PCOS (polycystic ovary syndrome), research confirms that while a reduction in carbohydrates can improve insulin sensitivity, no systematic superiority has been demonstrated compared to other balanced diets inducing a similar caloric deficit (systematic review, Nutrients). The suggested approach, which consists of pairing carbohydrates with proteins and fiber, is an effective strategy for satiety, supported by the principles of glycemic management and food satiety.
