Macro partitioning
The DASH diet does not significantly affect fasting glucose, Triglycerides (TAG), or HDL cholesterol concentrations.
Do not expect the DASH diet to significantly lower your blood sugar, Triglycerides, or raise your HDL cholesterol. Its primary benefits are on blood pressure and LDL cholesterol. Manage your expectations and focus on the proven benefits.

The pooled effect of the interventions was not significant for the concentrations of glucose (-0.19 mmol/l, 95% CI -0.39, 0.01, P=0.07), HDL (0.003 mmol/l, 95% CI -0.05, 0.05, P=0.95) and TAG (-0.005 mmol/l, 95% CI -0.06, 0.05, P=0.87).

More from this paper
- Adherence to the DASH diet significantly reduces systolic blood pressure (mean -5.2 mmHg), diastolic blood pressure (-2.6 mmHg), total cholesterol (-0.20 mmol/l), and LDL cholesterol (-0.10 mmol/l) in adults, leading to an estimated 13% reduction in 10-year cardiovascular disease risk.Strong
- The blood pressure-lowering effects of the DASH diet are greater in individuals with higher baseline blood pressure or higher BMI.Strong

- 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
