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'.

More from this paper
- Precision nutrition (PN) interventions, which tailor dietary recommendations based on individual genetic profiles, gut microbiota composition, and lifestyle factors, are more effective at improving diet quality, adherence, and metabolic outcomes in obesity management than generalized dietary guidelines.Moderate
- Dietary interventions targeting gut microbiota composition (e.g., prebiotics, probiotics, or specific fiber types) can improve glucose homeostasis and insulin sensitivity in obese individuals, particularly by modulating the Firmicutes/Bacteroidetes ratio and reducing pro-inflammatory bacterial species.Moderate
