Frequently Asked Questions

Quick answers to common questions

What calorie deficit produces 0.5kg of fat loss per week?+

0.5kg of body fat = ~3,850 calories. Target a 500 calorie daily deficit below TDEE. If your TDEE is 2,200 calories, eat 1,700 calories daily for ~0.5kg per week loss.

Is a 1,000 calorie per day deficit safe?+

A 1,000 calorie daily deficit is aggressive and often counterproductive. Risks include muscle loss, metabolic slowdown, nutrient deficiencies, and fatigue. Most evidence supports 500-750 calorie per day deficit as optimal.

Why did my weight loss stop despite staying in a calorie deficit?+

Plateaus occur from metabolic adaptation (TDEE decreases as you lose weight), reduced NEAT, measurement creep, or water retention. Recalculate TDEE at current weight and consider a planned diet break at maintenance.

Plateau advice

• Recalculate TDEE every 4–6 weeks as weight drops — your maintenance calories decrease.

• If progress stalls for 2+ weeks, reduce intake by 100–150 kcal or add 2–3 cardio sessions.

• Consider a 1-week diet break at maintenance every 8–12 weeks to manage hunger hormones.
