Is There a Magic Macro Ratio for Weight Loss?

A while ago, I came across someone saying that to find the perfect macro ratio for weight loss, you have to multiply your weight by 12 to figure out your maintenance calories and then use that to determine your protein, fat, and carb ratios. From the get-go, I could see that people were questioning this formula, as evidenced by the screenshots below, which I sourced from TikTok.

So, was the formula wrong? I decided to put it to the test. Seeing as I weighed 114 pounds at the time, that would have brought my maintenance calories to 1,368. Yet my actual maintenance calories range from 1900 to 2200 per day. It did not take me long to agree with the people in the comment section who felt that this formula does not apply to everyone.

Interestingly, that creator is not the only person I came across online who had this macro ratio for weight loss and this formula to calculate your maintenance calories. And I saw all the confusion that was in their comment sections. Their followers are not alone.

If you have ever started a diet, you have probably spent hours staring at a tracking app or looking for advice online, trying to hit a “perfect” target for your macros for weight loss. You have heard the Keto crowd say that you need 70% Fat, while the old-school bodybuilders say you need 50% Protein, and the “balanced” fitness gurus swear by the 40/30/30 zone or something similar.

The list of macro splits for weight loss goes on and on. And that is because we have been led to believe that weight loss requires a specific split, and if you do not have the exact percentage of carbs, fats, and proteins, you will not lose weight.

But have you ever noticed that people lose weight on Keto and on high-carb vegan diets? So, is there a perfect macro ratio for weight loss, or have we been so busy counting percentages that we have missed what actually works? That is what this guide covers in detail.

Do Macro Splits Matter? Must You Follow a Specific Macro Ratio For Weight Loss?

The list of macro ratios for weight loss is lengthy. We have 40-30-30, 80-10-10, 70-20-10; you name it. But away from the numbers, why do people think that these ratios matter?

The “Metabolic Advantage” Myth.

The truth is that much of the obsession that we have around macro splits comes from the idea of “Metabolic Advantage”, which is the belief that certain ratios “force” your body to burn more fat. You may have even heard someone say that if you follow a specific macro ratio for weight loss, you will definitely lose weight.

But luckily for us, we do not have to guess whether this holds up because science has put this to the test. A landmark study known as the DIETFITS study followed hundreds of people on either a “Healthy Low-Carb” or a “Healthy Low-Fat” diet for a full year. And according to the findings, there was no significant difference in weight loss between the groups. The ratios did not matter.

Other studies conducted over the years have come to the same conclusion – Your body can run on different ratios without any issue. In fact, the only difference comes in when we talk about the calories and the quality of the food.

But the effect on weight remains the same, provided that the calorie intake is equal.

The Role of Protein in Any Macro Ratio for Weight Loss.

Now, while there is no perfect macros split, priorities matter, and you may have noticed that many fitness influencers tend to focus more on protein than other macros. Why is that?

At the end of the day, the right macro ratio for fat loss is the one that helps you enjoy the foods you love without feeling deprived.

Calories versus Macro Ratios for Fat Loss.

If you have been reading my blogs or watching my videos for a while, I know I sound like a broken record when it comes to calories, but it’s because calorie deficits actually work.

You see, when it comes down to it, macro splits are just a way of organizing your calories so that you can understand how much fat, carbs, and protein you need to consume to hit your weight loss goals.

But if your split calls for 1,800 calories but you’re eating 2,200, you will not lose weight because you will be in a calorie surplus. In the same way, if your split is so restrictive that you binge every Friday night, you will not lose weight.

All in all, there is no universal macro split that works for everyone. Once again, the best macro ratio for weight loss is the one that allows you to stay in a calorie deficit without wanting to quit.

How to Perfect Your Macro Ratio for Weight Loss.

My Better in 90 Program, which helps women lose weight and keep it off, has a very flexible approach to macro splits, which I will share with you. Here is how you find your magic ratio:

Set Your Protein First.

Protein is not just great at keeping you full, but it also protects you from muscle loss when losing fat. So, aim for a 20–30% range or a 0.6–0.8g per pound of your body weight, and focus more on quality sources of protein. This comprehensive guide explains more about how much protein you need as an individual based on your activity levels and weight loss goals.

Gauge How You Feel.

Different macro splits have different effects on people. As such, you find that while one person may enjoy being on low carb, another might feel like a zombie on the same split. It is important to pay attention to how you feel.

For example, if high-carb meals make you sleepy, then you can increase the fats and lower the carbs. You do not have to work with generic splits, as these do not account for your individual preferences and needs.

Embrace the 80/20 Rule.

Instead of obsessing over macro splits for weight loss, focus on eating 80% whole foods while leaving the rest for other foods. That is because when you eat whole foods for the most part, the macros usually balance themselves out naturally because you’re getting enough fiber and nutrients. And this way, you also leave room for your favorite treats so that you do not feel deprived.

Join Better in 90.

Weight loss is not about perfecting your macros. Instead, it is about creating a lifestyle that you enjoy while paying attention to your calorie intake so that you remain in a deficit. And that is exactly the kind of balance that we strive for in Better in 90, where I work hand-in-hand with you to help you understand what works for you.
