Weight loss is a multifactorial process that is related not only to calories, but also to the hormonal system. It is a common situation to adopt. strict low-calorie diets with the aim of losing weight faster. However, the result is most often negative. When energy intake is restricted excessively and for a prolonged period of time, the body activates survival mechanisms that block the fat loss procedure.
First, strict dieting disrupts the normal regulation of glucose and insulin. Reduced carbohydrate intake leads to low glucose availability, which affects insulin release. Insulin, in addition to its well-known role in regulating blood sugar, also participates in lipid and protein metabolism. In conditions of malnutrition, the hormonal balance is disrupted, resulting in metabolic dysfunctions that may affect fat loss.
At the same time, excessive calorie reduction increases the production of cortisol, the stress hormone. Cortisol promotes the breakdown of fatty acids but at the same time enhances fat storage in the abdominal area, especially when it remains elevated for long periods of time. Additionally, elevated cortisol can disrupt sleep, reduce muscle mass, and increase cravings for energy-dense foods, making weight loss even more difficult.
The “plateau effect” is also a condition that most people who do restrictive diets end up in. This is essentially due to the very basic principle that the human body wants stable conditions. When these conditions are suddenly disrupted (e.g. a sudden weight loss) then it perceives it as a threat. Thus the basal metabolic rate decreases, as the body tries to maintain its energy. This phenomenon particularly affects women, whose hormonal system is more sensitive to dietary changes, especially during the reproductive age.
Furthermore, the psychological burden that accompanies a strict diet is not negligible. Constant control, deprivation and guilt over food can lead to a disturbed relationship with food, increasing the risk of episodic overeating or disconnection from natural hunger and satiety signals.
In conclusion, abrupt and prolonged calorie reduction can undermine the weight loss process itself. Instead of extreme diets, the scientifically proven approach includes gradual calorie reduction, adequate protein intake, a balanced plan based on each individual’s needs, and hormonal support, especially in women. Only in this way weight management can be effective and sustainable in the long term.
