Weight Loss Calculators • IIFYM • Macro Diet Plans For Weight Loss

IIFYM is a diet plan that stands for If It Fits Your Macros. It helps users lose weight by tracking macronutrients (protein, fat, and carbohydrates) without restricting food choices.

Macros are the only place calories come from so by hitting macros, users inherently hit weight loss calories.

Our clients report the IIFYM is the easiest and most sustainable weight loss plan they have ever followed. Many tell us that they don’t even feel like they are dieting, due to a large number of calories we often give them.
