There is a theory for those losing weight that muscle weight more than fat. It’s often stated after someone gains weight or struggles to see a good weight loss after doing a large amount of exercise. Many debate this often stating that a lb. of fat weighs the same as a lb. of muscle.

That is certainly the case.

A pound is a pound is a pound.…That is like saying a lb. of feathers weights the same as a lb. of lead. But the two don’t weigh the same when you consider size, and that is the same principle as muscle and fat.

A Lb. of Muscle Is Smaller Than a Lb. of Fat

While a lb. weighs the same as a lb., it’s important to think about the size. A lb. of lead is going to be much smaller in size than a lb. of feathers. Now let’s use that principle with the muscle and fat.

A lb. of muscle is much smaller than a lb. of fat. So, with that in mind, when you put muscle and fat of the same size together, the muscle will weigh more than fat.

How Does That Affect Your Weight Loss?

So, now that you know muscle does weigh more than fat, it is time to find out how that affects your weight loss.

The truth is that one week of exercise is not going to build the muscle that causes the weight gain. In fact, two or three weeks of exercise for the average person is not going to cause this. It takes time to build the muscle to replace the fat, and create it to such a density and size that it will weigh more than the original fat did.

Does That Mean Exercise Isn’t Worthwhile?

Of course now! Exercise is excellent for those losing weight, maintaining their weight loss or just trying to live healthier. You see, exercise helps to tone the body, and aids with the process of weight loss.

But don’t people who exercise gain weight? That is where the idea of muscle weighing more than fat comes from, right? Well, it is not likely to do with the muscle or fat. It could be your body going into “starvation” mode because you’re not eating enough.

When you do exercise, your body burns more calories. If you don’t eat enough, your body starts to panic that you’re not going to eat enough on a regular basis. To prevent it from starving, the body starts holding onto calories you eat by slowing your metabolism down. To see the benefits of exercise, you need to eat a little more—not too much so you eat more calories than you burn, but enough so you still see a good weight loss.

It’s a case of trial and error to find the one that works for you.

So, in conclusion, no muscle does not weigh more than fat. A pound is a pound, no matter what you are weighing. However, a lb. of muscle is smaller than a lb. of fat. That is the truth behind the theory.
