Macro partitioning
Adopting a low-fat dietary pattern (targeting 20% of energy from fat) with increased intake of vegetables, fruits, and grains does not cause weight gain in postmenopausal women over a 7.5-year period, and is associated with modest weight loss compared to a control group.
If you are a postmenopausal woman, switching to a diet lower in fat (around 20% of calories) and higher in vegetables, fruits, and whole grains will not cause you to gain weight, even if you do not count calories. In fact, you may lose a small amount of weight (approx. 2kg in the first year) compared to staying on your usual diet. Focus on replacing fat calories with plant-based carbohydrates rather than restricting total food volume.
A low-fat eating pattern does not result in weight gain in postmenopausal women.

- 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
