Understanding Your Complete Health Profile

Calorie Calculations

BMR (Basal Metabolic Rate) is the calories your body burns at rest for basic functions like breathing and circulation.

TDEE (Total Daily Energy Expenditure) includes your BMR plus calories burned through activity and exercise.

Target Calories are adjusted based on your goal - deficit for fat loss, surplus for muscle gain.

Specialized Equations

Spinal Cord Injury: Uses Nightingale & Gorgey equation accounting for 14-27% lower metabolism due to muscle atrophy.

Amputee: Adjusts body weight calculations based on estimated body weight before amputation.

Athletes: Ten Haaf equation accounts for higher muscle mass and metabolic rate in active individuals.

Autism Spectrum Disorder: Research-based 15-20% BMR increase accounting for 67% more neurons in prefrontal cortex, mitochondrial dysfunction, and chronic stress response.

Hypothyroidism (Untreated): Uses Mifflin-St Jeor equation with severity-based adjustments accounting for reduced thyroid hormone production causing 2-30% lower metabolism. Activity levels are capped at moderately active for cardiovascular safety, with conservative 5-15% calorie deficits to prevent further T3 suppression. Research shows very low calorie diets can reduce T3 by 40-66%, worsening the condition, so minimum intake thresholds and higher protein targets (1.4g/kg) are enforced to preserve muscle mass and thyroid function.

Spina Bifida: Uses SCI-validated Nightingale & Gorgey equation with type-specific, lesion-level, and mobility-based adjustments. Energy needs reduced by 14-50% due to decreased lean muscle mass, lower basal metabolic rate, and reduced physical activity. Myelomeningocele with higher lesions (thoracic) shows greatest metabolic suppression (30% reduction), while occulta requires no adjustment. Activity multipliers use SCI-specific METs for wheelchair users. Conservative calorie deficits (15-20% max) ensure safe weight loss. Active pressure ulcers contraindicate restriction and increase needs by 20-50%. BMI is unreliable—DEXA body composition assessment recommended.

BMI Assessment

Body Mass Index provides a quick screening tool for weight categories, but remember it doesn't account for muscle mass or body composition.

Your healthy weight range shows the weight range associated with a BMI of 18.5-24.9 for your height.

Macronutrient Targets

Protein, carbohydrates, and fats are calculated based on your goals:

Fat Loss: Higher protein to preserve muscle
Maintenance: Balanced macros for health
Muscle Gain: Higher protein and carbs for growth

Track Your Intake

Use your target calories and macro goals to plan meals and monitor your nutrition intake consistently.

Monitor Progress

Weigh yourself regularly and adjust your targets if you're not seeing expected progress after 2-3 weeks.

Focus on Quality

Hit your macro targets with whole foods: lean proteins, complex carbs, and healthy fats for best results.
