Macro partitioning

Specific genetic variants (e.g., FTO, TCF7L2, FABP2) modify the body's response to macronutrient intake, such that high-protein or specific fat/carbohydrate ratios yield different weight loss or metabolic outcomes depending on the individual's genotype.

If you have known genetic risks (like FTO variants), standard high-carb or low-fat diets might not be optimal. Consider discussing with a professional whether a high-protein or specific fat-modified diet aligns with your genetic profile for better weight management.

A high-protein diet in the presence of FTO genotype: (1) Remarkable weight loss (2) Amelioration in body composition and lipid distribution.

Why this rating

Based on specific GWAS and intervention studies cited in the review, but the paper notes the impact of many SNPs on BMI is 'modestly rated'.
