Not Medical or Nutritional Advice
The calculators, tools, and content provided on MacroDeficit (macrodeficit.com) are intended for general informational and educational purposes only. Nothing on this Site constitutes medical advice, nutritional advice, or a substitute for professional consultation with a qualified healthcare provider, registered dietitian, or physician.
The results generated by our calculators — including TDEE estimates, calorie targets, macro recommendations, protein intake suggestions, and BMI classifications — are mathematical estimates based on population-level formulas. They are starting points, not prescriptions. Individual results will vary based on factors that these calculators cannot account for, including medical conditions, medications, hormonal factors, and genetics.
Consult a Professional
Before making any significant changes to your diet, calorie intake, exercise program, or lifestyle based on information from this Site, please consult a qualified professional. This is especially important if you:
- Have any existing medical conditions, including diabetes, heart disease, kidney disease, or eating disorders
- Are pregnant or breastfeeding
- Are under 18 years of age
- Are taking any medications that may be affected by dietary changes
- Have a history of disordered eating
Formula Accuracy
Our TDEE calculator uses the Mifflin-St Jeor equation, which research supports as one of the more accurate formulas for estimating basal metabolic rate in the general population. However, no formula is perfectly accurate for every individual. We recommend treating calculator results as a starting estimate and adjusting based on real-world results over 2-4 weeks of consistent tracking.
Our BMI calculator uses standard WHO classifications. BMI has well-documented limitations — it does not distinguish between muscle and fat, does not account for fat distribution, and may be less accurate for certain populations including athletes, older adults, and individuals of certain ethnic backgrounds.
No Liability
MacroDeficit and its operators accept no liability for any health outcomes, injuries, or adverse effects that may result from reliance on the information or calculator results provided on this Site. Use of this Site and its tools is entirely at your own risk.
