πŸ’‘ Uses the Mifflin-St Jeor equation, the most accurate BMR formula for most people. TDEE multiplies BMR by your activity level. These are estimates β€” adjust based on real-world results over a few weeks. Not medical advice.

Weight Loss tips

πŸ“‰

A 500-calorie daily deficit targets roughly 0.5kg (1lb) of fat loss per week.

πŸ’‘

Don't go too aggressive β€” very low intake is hard to sustain and costs muscle, not just fat.

🎯

Track real results for 2–3 weeks and adjust; the formula is a starting estimate, not a guarantee.
