In this post, we will discuss the science behind counting calories for weight loss and health.

Calories and Macronutrients

Calories are a measure of energy in food and drinks. Macronutrients, on the other hand, are a measure of the fat, carbohydrates, and protein in the food. Macronutrients and the ratio of each play an important role in weight loss and health, as they provide the body with the building blocks it needs to heal and perform optimally. Protein, for example, is important for muscle growth, while carbohydrates are an important source of energy.
