Macro partitioning
Obese individuals exhibit a specific, differential pattern of dietary underreporting where total energy intake is underreported significantly more than protein intake, leading to an overestimation of the proportion of energy derived from protein.
If you are obese, your self-reported diet likely underestimates your total calorie intake more than your protein intake. This means your calculated 'protein percentage' of total calories is likely artificially high. To get an accurate picture of your macronutrient balance, rely on biomarkers or objective measures rather than just your memory of what you ate, as you likely omit high-carb/fat snacks while remembering protein sources.
Degree of obesity was positively associated with underreporting of total energy and protein, whereas compared with total energy reported, protein was overreported by the obese subjects.
Why this rating
The study uses robust biomarkers (24h urinary nitrogen and doubly labeled water proxy via activity levels) to validate self-reported data, minimizing the primary bias it studies.

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
