Not all calories are created equal.
Different foods go through different metabolic pathways in your body.
They can have vastly different effects on your hunger, hormones and the number of calories you burn.
The Dietary Reference Intake (DRI) for protein is 0.36 grams per pound of body weight, or 0.8 grams per kilogram.
However, a lot of evidence supports a higher protein intake for weight loss and other health benefits.
This article takes a detailed look at protein’s beneficial effects and provides guidance for achieving the best results on a high-protein diet.
Protein is one of the three macronutrients, along with carbs and fat.
In your body, it performs the following roles:
- Repair and maintenance: Protein is the main component of your muscles, bones, skin and hair. These tissues are continuously repaired and replaced with new protein.
- Hormones: Chemical messenger proteins allow cells and organs in your body to communicate with each other.
- Enzymes: Most enzymes are proteins, and the thousands of chemical reactions that take place throughout your body are driven by them.
- Transportation and storage: Some proteins help deliver important molecules where they’re needed. For example, the protein hemoglobin carries oxygen to your body’s cells.
