What are Macronutrients and how do they play into my nutrition plan? The three macronutrients are Protein, Fat, and Carbohydrate. They are called “macro” since large quantities of them are needed to fuel the body. Note that proteins and fats are needed to survive. Macronutrients supply energy and are necessary for growth and repair of the body. The RDA recommends a .8 grams of protein per kg of bodyweight and 20% to 35% of total calories for Fat. RDA recommendations are the minimum necessary to prevent disease.
Carbohydrates are not an essential nutrient but are part of foods that are essential. Eat only the amount of carbs necessary to support your activity level. The attached chart (curtesy of ISSA) will provide some key information on Macronutrients.
Let me leave you with a few helpful pointers from Michael Pollen:
“If it comes from a plant eat it.”
“Don’t eat anything incapable of rotting.”
“Don’t eat anything your great-grandmother wouldn’t recognize as food.”
