Whether you’re following a time tested method, fad diet, or simply just improvising, a foundational understanding of the core macronutrients, protein, fats and carbohydrates is relevant to any diet. Each of these categories of nutrients has a varying degree of necessity to our bodies and how much you require of any of them will be almost always be unique to the individual, may change over time and for different reasons.
If you follow a “calories in, calories out” or macronutrient ratio model, you’re likely giving the lion’s share of your dietary focus to the energy you’re receiving from food. This, at least in part, makes sense. We certainly need energy for each movement we make and just as much to perform the countless biochemical processes throughout the day. In the simplest forms, our bodies rely on the consumption or creation of glucose for energy. Glucose is a form of sugar we mostly obtain through dietary carbohydrates.
