IIFYM RMR Calculator

A human body doesn’t require any energy to store fat, but it does for muscle. That’s why most diets fail. Abrupt reduction in calorie intake leads to muscle and fat realignment.​

The IIFYM RMR Calculator is used to calculate one Resting Metabolic Rate which is very similar to ones BMR or Basal Metabolic Rate with a few differences. RMR is a very useful tool for flexible dieting with IIFYM techniques in mind.

The person that is flexible dieting quickly loses weight, muscle and fat. When normal consumption is resumed the weight quickly rebounds because the body is now burning fewer calories to sustain itself.


Don’t Get Confused!

Many people confuse the results from our BMR calculator and RMR calculator.
They are very similar so it might be easy for you to get the mixed up. Be careful however.. Many weight loss tools look the same and we don’t want you to fall prey to the Crap that leads other people down that same path.
