COMMON QUESTIONS

Frequently Asked Questions

Macronutrients (macros) are the three main types of nutrients your body needs in large amounts: Protein (4 cal/g), Carbohydrates (4 cal/g), and Fats (9 cal/g). They provide the energy your body requires to function.

There is no single "best" ratio. Most healthy adults do well with 30% protein, 40% carbs, and 30% fat. However, athletes or those on specific diets (like Keto) will require different distributions.

You should recalculate your macros every time your weight changes by 5-10 lbs, as your body's energy requirements shift with your new mass.

For those looking to build or preserve muscle, protein is crucial. However, fats are essential for hormone health and carbs are the body's primary energy source. Balance is key.
