Macro partitioning
Ultra-processed foods drive obesity primarily through their high glycemic load and disrupted cellular structure, which accelerates digestion and hormonal response, rather than just their energy density.
Minimize ultra-processed foods, especially those high in carbohydrates. Whole foods retain cellular structures that slow digestion and blunt glycemic spikes, reducing the hormonal drive for fat storage.
GoodSupportsHIGH confidence
The cellular structure of plants, including cellulose and soluble fibers, protects intrinsic carbohydrates from enzymatic digestion and diffusion to the gut wall. Extensive food processing disrupts this structure, resulting in acellular starches and sugars with markedly increased GL and adverse health effects.
Why this rating
Supported by Table 3 and references to studies on food structure and glycemic response.

- 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
