Macro partitioning
The metabolic benefits associated with Bifidobacterium longum and Faecalibacterium prausnitzii are conditional on dietary intake, specifically disappearing after adjusting for carbohydrate (fiber) and fat intake, respectively.
If you consume probiotics like Bifidobacterium longum or Faecalibacterium prausnitzii, ensure your diet includes adequate dietary fiber and healthy fats. The study suggests these bacteria's metabolic benefits are linked to these macronutrients, so combining them with a fiber-rich, balanced diet may be more effective than the bacteria alone.
ModerateConditionalMEDIUM confidence
the negative correlation with insulin resistance observed for B. longum and F. prausnitzii appeared to be modified by the intake of dietary fibre and fat, respectively.

- 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
