Your measurements indicate severe underweight status. This tool cannot provide weight-loss recommendations for this profile.
Maintenance-level calorie targets are shown instead. Please consult a qualified healthcare professional before making any dietary changes.
Your BMI falls below the normal range. Weight-loss recommendations may not be appropriate. Consider consulting a qualified healthcare professional.
Aggressive weight-loss pace has been disabled. Your calorie deficit has been limited to a maximum of 300 kcal/day for your safety.
Nutrition and calorie needs for individuals under 18 may differ from adult recommendations. Results should be reviewed with a parent, guardian, or healthcare professional.
Aggressive calorie deficits have been capped at 300 kcal/day. This tool is designed for general adult use.
You are already at your selected target weight. Maintenance recommendations are shown.
Your current weight matches your target. Calorie targets reflect your maintenance energy expenditure.

Your 7-Day Meal Plan
Portion sizes are dynamically optimized to align as closely as practical with your personalized calorie and macronutrient targets while using realistic serving sizes appropriate for your selected dietary preferences, region, and budget.
Nutrition estimates are based on established food composition databases and standard serving references. Actual values may vary due to ingredient brands, regional food products, preparation methods, recipes, and natural food variability.
Food exclusions personalize meal suggestions but do not guarantee an allergen-free meal plan. Always review ingredient labels carefully and consult a qualified healthcare professional if you have severe food allergies, medical conditions, or specific dietary requirements.

Why This Plan Works
Scientifically Calibrated Calculations
Used as the core BMR predictor, validated by clinical reviews as the most consistent baseline predictor in modern weight management.
BMR = 10*W(kg) + 6.25*H(cm) - 5*A(y) + s (+5 Male, -161 Female)Computes body fat percent dynamically from waist, neck, and height dimensions without requiring bioelectrical impedance scales.
Male: 86.01*log10(Waist-Neck) - 70.041*log10(Height) + 36.76Female: 163.205*log10(Waist+Hip-Neck) - 97.684*log10(Height) - 78.387Classifies BMI indexes into underweight, normal weight, overweight, and obese ranges as documented by the World Health Organization.
BMI = Weight(kg) / (Height(m))^2Why These Formulas Are Trusted
Scientifically calibrated formulas.
How Calories Are Calculated
Calories are calculated by estimating your Basal Metabolic Rate (BMR)—the energy required to sustain life at rest—using the clinically validated Mifflin-St Jeor Equation.
Women: BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (y) - 161
What Is TDEE
Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in 24 hours, incorporating your active movement, workouts, and lifestyle factors mapped to resting metabolism.
• Sedentary (1.2) • Light (1.375) • Moderate (1.55) • Active (1.725) • Very Active (1.9)
What Is BMI
Body Mass Index (BMI) is a standardized screening metric established by the World Health Organization (WHO) to evaluate body mass categories relative to height.
• Underweight (< 18.5) • Normal (18.5 – 24.9) • Overweight (25 – 29.9) • Obese (≥ 30)
What Is Body Fat %
Body Fat Percentage represents the proportion of adipose tissue relative to lean mass, calculated using neck, waist, and hip circumference measurements via the US Navy method.
Women: BF% = 163.205 × log10(waist + hip - neck) - 97.684 × log10(height) - 78.387
How Weight Projection Works
Weight projection estimates the rate of body mass change by simulating caloric deficits or surpluses over time, enforcing clinical floor safety limits to prevent nutrient deprivation.
• 1 kg of body fat loss ≈ 7,700 kcal cumulative deficit
• Safety floors: 1,500 kcal/day (males) and 1,200 kcal/day (females)
