If your answer to both queries is 'yes', then you've likely experienced a metabolic disorder - a state in which your body defends itself against further weight loss. Despite numerous hours spent in the gym and meticulous calorie counting, you still can't shed excess fat? You exercise and follow a diet, but your efforts yield no results? Are there any reasons for this situation and how can one prevent it?

Metabolic stagnation
Metabolic stagnation refers to a condition in which the body fails to burn fat despite adhering to a balanced diet with moderate calorie restriction. Despite maintaining a healthy reductive diet and engaging in regular physical activity, weight remains unchanged. Metabolic processes do not function properly for unknown reasons, hindering further fat loss. This state is often considered a subclinical form of hypothyroidism, as typical symptoms such as irregular appetite, body temperature fluctuations, mood swings, decreased libido, and general fatigue manifest despite normal TSH, T3, and T4 levels. The longer this condition persists, the more challenging it becomes to repair bodily damage and restore normal metabolic function.

Factors contributing to metabolic collapse
The primary factor leading to metabolic dysfunction is the prolonged adherence to highly restrictive or moderately restrictive weight-loss diets. Regimens such as the high-protein Dukan diet, low-calorie, or low-fat diets can induce irreversible metabolic alterations, causing a progressive slowdown in metabolic rate. The principle of "all or nothing" applies here – the faster the transition from a high-calorie diet to an extremely low-calorie one, the greater the likelihood that the body, shocked by such abrupt changes, will respond with resistance.

Preventive strategies for metabolic disruption – essential approaches
Research consistently shows that prevention is far more effective than treatment. To avoid metabolic disruptions, it's crucial to steer clear of risk factors such as calorie deficits, inadequate diets, excessive training, and abrupt changes in energy balance. If already following a reduction diet, changes should be gradual to allow the body time to adapt. A key strategy is the reverse diet, which involves a gradual 15-20% increase in calorie intake. During fat loss, weight loss should not exceed 0.5 kg/week for women and 1 kg/week for men. The goal should be improving body composition by increasing muscle mass while reducing fat. Instead of prolonged cardio sessions, high-intensity HIIT, Tabata, or compound exercises are preferable. Additionally, mindful carbohydrate cycling can help mitigate the risk of metabolic disruptions.
