Personalised plan

Your plan. Your rules. Every week.

KCALS generates a fresh 7-day meal plan every week — automatically adjusted to your calorie zone, food preferences, and even the day of the week. Monday is not the same as Friday.

Stressful week? KCALS drops your deficit automatically — no willpower needed. Log your mood, sleep and energy with each check-in and watch your plan adapt in real time.

Anti-plateau engine

Hit a wall? KCALS sees it before you do.

A ready-to-follow 7-day meal plan with breakfast, lunch, dinner and snacks — all within your calorie budget.

4. Track & Adapt

Log your weight and mood weekly. KCALS adjusts your deficit zone to keep you on track without burning out.

Your Psychological Zone

Not everyone is ready for an aggressive deficit. KCALS respects your mental state.

🟱 Green Zone

Aggressive Mode

Low stress + high motivation. You're ready for a 25% calorie deficit — maximum fat loss, sustainable pace.

🟡 Yellow Zone

Balanced Mode

Middle ground. A 15% calorie deficit — steady progress without overwhelming your routine.

🔮 Red Zone

Sustainable Mode

High stress or low motivation. Just an 8% deficit — build the habit first, results follow naturally.
