IIFYM, or “If It Fits Your Macros,” is a type of flexible dieting that helps people lose weight without feeling overly restricted.

Rather than focusing on calories, IIFYM tracks macronutrients instead — namely protein, fat and carbohydrates.

This allows for much more flexibility since all foods can be enjoyed as long as they fit into your macros for the day.

The IIFYM diet was originally designed by fitness enthusiast Anthony Collova after he became frustrated with traditional dieting recommendations.

IIFYM is a new spin on dieting that focuses on macronutrients rather than calories.

IIFYM Recipes

Macronutrients, or macros, are the four types of food molecules the body can break down for energy. Three types of macronutrients are tracked in IIFYM:

  1. Protein, which has 4 calories per gram.
  2. Carbohydrates, which have 4 calories per gram.
  3. Fat, which has 9 calories per gram.

Alcohol is the fourth macronutrient, containing 7 calories per gram, but it’s not included in the IIFYM diet.

Since IIFYM focuses on macronutrients, rather than calories. It can be a great educational tool for people who are unfamiliar with the macronutrient composition of foods.

For example. A Snickers bar and 5.5 ounces of salmon have almost the same number of calories but, very different macronutrients.

While the candy bar and salmon both contain a large amount of fat, the Snickers bar is loaded with carbohydrates. While the salmon is packed with protein (1, 2).

It’s easy to see how learning to meet your macros can be an eye-opening experience. For someone who has not tracked them before.

Quick Start Guide

IIFYM is an acronym for If It Fits Your Macros and has become a popular dieting trend. IIFYM is also known as flexible dieting or counting macros.

The crux of the diet revolves around two main concepts; establishing your personal TDEE (Total Daily Energy Expenditure)2 and establishing your personal set of daily macro (macronutrient) targets.

Quick Start Guide

The first thing a dieter must do when beginning IIFYM is to establish their TDEE or in other words, how many calories their body burns during a 24 hour period considering their REE (Resting Energy Expenditure), their general movement/activities, and their intentional exercise.

The amount of macros you should be eating for weight loss will be different than anyone else’s. First, you’re going to find your “macronutrient ratio” – a ratio that takes into account your height and weight, activity level, age, and weight loss goals. There are calculators and apps to help you find your macro ratio such as the macro diet.

If you’re calculating your macros for weight loss, the following ratio will be a good starting point for you: 10-30% carbs, 40-50% protein, 30-40% fat. Make sure to tweak your macros taking into account the results you’re looking for and your activity level.
