Micronutrients & recovery
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.
Focus on dietary fibers and fermented foods to support a healthy gut microbiome. This may help improve insulin sensitivity and reduce inflammation, which are key drivers of obesity and metabolic syndrome.
The transplantation of faecal microbiota has been reported to reduce body fat accumulation two weeks post-procedure in germ-free mice... individuals’ gut microbiota can be used to design personalised diets for glucose homeostasis.
Why this rating
Supported by animal studies and some human observational data, but the paper notes 'further confirmation by causal, quantitative, and/or appropriate mechanistic analysis is worth pursuing'.

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
- 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.Moderate
