Calculateur de chronologie de perte de poids

Most health professionals recommend losing 0.5 to 1 kg (1 to 2 lbs) per week. Losing weight faster than this increases the risk of muscle loss, nutrient deficiencies, and metabolic slowdown. A moderate deficit of 500-750 calories per day supports sustainable fat loss.

Plateaus occur because your body adapts to a lower calorie intake by reducing metabolic rate. As you lose weight, your body needs fewer calories to maintain itself. Breaking through requires recalculating your deficit, varying exercise intensity, or taking a short diet break.

Eat adequate protein (1.6-2.2g per kg of body weight), do resistance training at least 2-3 times per week, avoid extreme calorie deficits, and prioritize sleep. Losing weight slowly (0.5-0.75 kg/week) preserves significantly more muscle than rapid weight loss.

Timeline calculators give a useful estimate but real progress varies. Water retention, hormonal fluctuations, sleep, stress, and metabolic adaptation all affect the rate of loss. Expect the actual timeline to be 10-20% longer than the estimate, and track trends rather than daily numbers.
