Science-based articles on TDEE, macronutrients, calorie deficit, BMI and healthy recipes. Evidence without myths.
TDEE (Total Daily Energy Expenditure) is the total number of calories you burn in 24 hours. Learn its four components, the most accurate formula and how to use it to lose fat or gain muscle.
Read article →BMR and TDEE are related but very different concepts. Confusing them is one of the most common errors in nutrition. Find out what each measures and why the difference matters.
Read article →Can you really speed up your metabolism? Science points to 4 real levers — and debunks several popular myths. Find out what actually works.
Read article →TDEE is not a fixed number. Age, sex, hormones and body composition constantly modify it. Learn the most relevant factors and how to adapt your nutrition strategy.
Read article →Macronutrients — protein, carbohydrates, and fat — are the building blocks of nutrition. Learn what each provides, calories per gram, and why tracking macros beats counting calories alone.
Read article →Find the optimal macronutrient split for fat loss. High protein to preserve muscle, moderate carbs, and minimum fat within a sustainable caloric deficit — with a goal-based reference table.
Read article →Learn the optimal macros for building muscle. Protein 1.6–2.2 g/kg per the Morton et al. 2018 meta-analysis, carbs for glycogen, and a moderate 200–400 kcal surplus for maximum hypertrophy.
Read article →Compare macronutrient ratios by goal: cutting, maintenance, bulking, ketogenic diet and body recomposition. Based on the AMDR ranges from the Institute of Medicine.
Read article →A calorie deficit means eating less than you burn. Learn the energy balance equation, why the 3,500 kcal rule is an approximation, how your body adapts, and how to apply it effectively.
Read article →A 300–500 kcal/day deficit is the optimal range for losing fat without sacrificing muscle. Learn the risks of very low calorie diets and why protein intake is critical to preserving lean mass.
Read article →Weight loss plateaus have concrete physiological causes: metabolic adaptation, NEAT reduction, and hormonal shifts. Learn what the science says and how to recalibrate your deficit to keep progressing.
Read article →Meta-analyses show that diet outperforms exercise alone for fat loss, but the combination is optimal. Discover why exercise is essential for muscle preservation and long-term weight maintenance.
Read article →BMI (Body Mass Index) measures weight relative to height. Learn the formula, WHO categories, history of the Quetelet index, and why BMI has important limitations for assessing real health.
Read article →Healthy BMI ranges shift across the lifespan. Children use percentile charts, adults follow WHO 18.5–24.9, and older adults may benefit from a slightly higher range. See the evidence-based table by age group.
Read article →BMI and body fat percentage do not measure the same thing. Learn why BMI fails in athletes and normal-weight obese individuals, and when to use more accurate metrics like DEXA or waist-to-height ratio.
Read article →Lowering BMI requires a caloric deficit plus resistance training to preserve muscle. Learn the realistic rate of BMI reduction, the role of sleep, protein intake, and NEAT in lasting fat loss.
