Macro partitioning

A 21-day Daniel Fast, characterized by the consumption of plant-based foods while excluding animal products, refined carbohydrates, and additives, significantly improves cardiovascular risk markers including blood pressure, total cholesterol, and LDL-C, and reduces biomarkers of oxidative stress and inflammation.

To try a Daniel Fast, eat only whole plant foods (fruits, veggies, whole grains, legumes, nuts, seeds) and water for 21 days. Avoid all meat, dairy, refined sugars, white flour, additives, caffeine, and alcohol. You can eat as much as you want of the allowed foods. This approach has been shown to lower blood pressure and cholesterol significantly.
