Why a Personalised Plan
Beats Generic Diets
Belly fat responds to the right deficit, the right protein, and the right training. Heumin calculates all three.
Precise Calorie Deficit
Not too aggressive (which kills muscle), not too mild (which stalls progress). Our AI finds your sweet spot — 300–500 kcal below maintenance.
Protein-First Meals
1.6–2g protein per kg bodyweight preserves muscle while you lose fat. Every meal is calculated to hit your target without counting macros yourself.
Workout + Meals Together
Pre-workout carbs fuel your session. Post-workout protein aids recovery. The AI times everything around your training schedule.
How Our AI
Targets Belly Fat
We use the scientifically validated Mifflin-St Jeor equation to calculate your Basal Metabolic Rate, then create a precise calorie deficit that burns fat while preserving lean muscle mass.
The Formula
BMR = (10 × weightkg) + (6.25 × heightcm) − (5 × age) + 5
Then multiplied by your activity factor (1.2 - 1.9) and deficit (15-25%)

Belly Fat Loss FAQ
Can I target belly fat specifically?
You can't spot-reduce fat — crunches build ab muscles but don't burn belly fat specifically. However, a calorie deficit combined with strength training will reduce overall body fat, and belly fat will shrink as part of that process. The AI builds both your deficit and training plan together.
Why is belly fat the hardest to lose?
Lower belly fat has more alpha-2 adrenergic receptors that resist fat breakdown, plus lower blood supply. It's typically the last area to lean out. Consistency with your deficit and strength training is key — there's no shortcut, but the right plan makes it systematic.
How fast can I lose belly fat?
With a moderate deficit (300–500 kcal/day), expect 0.5–1 kg of total fat loss per week. You'll notice your waist shrinking within 2–3 weeks. Belly fat specifically may take 4–8 weeks to show significant visual change, depending on your starting point.
Do I need to cut carbs to lose belly fat?
No. You need a calorie deficit — not carb restriction. Carbs fuel your workouts and recovery. Heumin's AI calculates the right balance of protein, carbs, and fats for your body. Cutting carbs too aggressively often backfires by killing energy and workout performance.
Evidence-Based Approach
Every recommendation is backed by peer-reviewed research. Our calorie calculations use the Mifflin-St Jeor equation — the gold standard in clinical nutrition — combined with AI that adapts to your progress week by week.
