Frequently Asked Questions
What is a safe caloric deficit for weight loss?
A safe caloric deficit ranges from 300-750 calories per day, depending on your approach. Conservative (300-500 kcal/day) is slow but sustainable, moderate (500-750 kcal/day) offers balanced progress, while aggressive (750-1000 kcal/day) requires medical supervision and experience.
How much weight can I safely lose per week?
Safe weight loss rates depend on your starting weight: normal weight individuals should aim for 0.5-0.8 kg/week, overweight individuals 0.8-1.0 kg/week, and obese individuals 1.0-1.2 kg/week. Faster rates may compromise health and muscle mass.
What are the minimum daily calories I should consume?
Never go below minimum safe levels: women should consume at least 1200 kcal/day and men at least 1500 kcal/day. Going below these thresholds can cause nutritional deficiencies, muscle loss, and metabolic slowdown.
How do I calculate my caloric deficit?
The basic formula is: Deficit = TDEE - Daily calorie intake. To lose 1 kg of fat, you need approximately 7700 calories of cumulative deficit. Track consistently for 2-3 weeks to verify accuracy and adjust based on actual results.
What macronutrient ratios should I follow during a deficit?
During caloric deficit, prioritize muscle preservation with 1.6-2.2g protein per kg body weight, 45-55% of calories from carbohydrates for energy, and 20-30% from fats for hormones and vitamins. Adjust based on training demands and personal preferences.
Why does weight loss slow down over time?
Metabolic adaptation is a natural response where metabolism slows 3-5% for every 10% of weight lost. The body becomes more efficient, and hormonal changes affect hunger and satiety. Combat this with periodic refeed days and plan adjustments.
