Animal-based diets high in saturated fats and proteins promote the growth of bile-tolerant and proteolytic bacteria, leading to the production of potentially harmful metabolites like TMAO, ammonia, and hydrogen sulfide, which are linked to inflammation and cardiovascular disease.
If you consume animal products, be aware that high intake of red meat and saturated fats can promote gut bacteria that produce harmful metabolites like TMAO and hydrogen sulfide, linked to heart disease and inflammation. Balance animal proteins with high-fiber plant foods to encourage beneficial SCFA production and mitigate these risks.
An animal-based diet... determines the increase of bile-tolerant microbes such as Alistipes, Bilophila, and Bacteroides... The metabolites such as amines, hydrogen sulfide, p-cresol, and ammonia, are harmful for the colonic epithelium at excessive concentrations... TMAO decreases the transport of reverse cholesterol and bile acid synthesis... explaining the relation between bile acid and TMAO regulation emerging as a possible atherosclerosis mediator
Why this rating
Strong mechanistic evidence from multiple studies cited, linking specific metabolites to disease states.

- 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
