How to lose weight with CrossFit?

Losing weight remains one of the most common problems of the general population. Moreover, it is recurrent because people are used to follow a diet, instead of learning how to eat. In most cases, people follow a diet, and then they will get some improvement and after weeks of sacrifices, they abandon the diet and a rebound effect will happen and leaving them worse than they were at the beginning.

Losing weight is a task that involves working on several areas at once. There is no magic, no one can tell you that just doing CrossFit, or dieting, or taking this supplement...

It is imperative that your CrossFit training is accompanied by a proper diet. This word is scary, but dieting does not mean to be on broccoli and boiled chicken, but to learn to eat well and forever.

If you want to lose weight once and for all, there is only one way: changing your lifestyle..

Myths about CrossFit and weight loss

Let's look at some of the most repeated questions regarding CrossFit and the supposed magical effects. Let's look at the truth and only the truth, because CrossFit has a lot of good things, it has everything you need. 🙂

I want to do CrossFit to lose fat from my bell and legs only.

No one (except a cosmetic surgeon) can assure you that you will lose lose weight from here or there. Not even in a CrossFit class.

The physical adaptations of this sport involve a body fat loss without being able to choose from where! and an increase in muscle mass.

The only way you could focus your efforts on a particular area would be to target muscle hypertrophy (growing muscles) with a specific program. Normally, the training that is done in the fitness gym is with analytical exercises that can target an specific area. But it only refers to the muscle gain, never to fat loss.

I have gained weight since I've started CrossFit

The scale can be one way to assess fat loss, but it should not be the only way, as it can cause you to come to false conclusions such as "I weigh more, I'm not losing fat".

Muscles are part of the evolution process in CrossFit. They must be valued as a positive gain. In addition, they are denser than fat, which means that for the same volume, muscle weighs more than fat.

For a good analysis of your evolution, tape measurements can help. Many times it is enough to look in the mirror to see that you have less waist, and more gluteus, for example. But if you are one of those who like to do an exhaustive follow-up, do not stay only with the number on the scale, use the tape as well.

That time when I didn't do sports, when I almost weighed 100 kilos, when I got tired quickly, when I often had headaches, slept badly... I can't be happier about my change during this time. I feel more awake, more agile, healthier, more self-confident ...


I don't want to do CrossFit because I gain muscle too fast.

We have said that, with CrossFit you get to lose weight and gain muscle, but it's not all that fast as we think. In particular muscle gain is usually a slower process.

There are different types of metabolisms with more or less ease in achieving an athletic body with less fat and more muscle, but still, no one sets foot in a CrossFit box and automatically starts growing new muscles like mushrooms.

If we look for information about CrossFit we see elite athletes who are fully dedicated to this sport and we compare ourselves with them, we will be making a big mistake. 

We cannot think that we will have the physique of Mat Fraser or Tia Toomey's husband who are the fittest people in the world for several years in a row. Their volume of workouts, meals, breaks... has nothing to do with yours or mine who practice CrossFit for fun. So don't worry about picking up a barbell, you won't automatically become the Hulk.
