What Is the Best Macronutrient Ratio? A Guide

Macronutrients are food sources that are broken down into three major categories: carbs, proteins, and fats. This includes things like bread and pasta, meat and beans, and avocados and nut butter. 

Macronutrients are the pillars of energy. In other words, you need them to stay energized throughout the day. The question is, what is the best macronutrient ratio for your lifestyle?


When we're talking about a macronutrient-based diet, we're talking about the percentage of calories consumed per day that come from specific sources. Broadly speaking, many adults can shoot for a diet of 45-65% carbs, 10-35% protein, and 20-35% fat. How can you cater this to your goals?

Read on for our guide to the best macronutrient ratio for your lifestyle and goals.

Best Macronutrient Ratio for Weight Loss

We all know the general rule of thumb regarding weight loss: you want to burn more fuel than you consume. However, we see a lot of fad diets that tell you to reduce or cut certain food types, altogether, and this isn't necessarily the best way to go about it.

If you're trying to lose weight, adjust your macronutrient ratio to:

  • 45-50% carbs, eating primarily lower-glycemic carb sources like whole wheat pasta and sweet potatoes
  • 25-30% protein, which can help to boost metabolism throughout the day
  • 20-25% fat, focusing on unsaturated fats and essential fatty acids like fish oil or nuts and seeds

Combined with an increased exercise regimen, this ratio can help you sustainably lose weight.

Best Macronutrient Ratio for Active People

We consider active people anyone who partakes in general fitness for about three to five hours per week. This can include a combination of cardio, aerobics, weight lifting, and moderate-intensity exercise.

To support your active lifestyle, adjust your macronutrient ratio to:

  • 45-50% carbs, eating lower-glycemic carbs later in the day
  • 10-15% protein, making sure to consume protein sources before exercising
  • 25-35% fat

If you find that you're running low on energy, consider adjusting these ratios as needed. Understand why it's important to eat the right macronutrients to support your workout.

Best Macronutrient Ratio for High-Intensity Training

If you work out for one to two hours per day, four to six days per week, this is considered high-intensity training. Talk to a nutritionist to get more specific guidelines based on the type of training you're doing.

In the meantime, to support your high-intensity training, adjust your macronutrient ratio to:

  • 55-65% carbs, skewing higher to replenish spent energy
  • 20-30% protein, skewing higher if you are building muscle mass
  • 30% fat

Remember, these numbers may need to shift depending on the type of training you are doing.
