I know, I know. I can hear your questions and comments. Doesn’t muscle weigh more than fat? Then how can adding muscle help me lose weight? Adding muscle means I’m going to weigh more. I feel bulky as it is, I want to lose size not add size.
Let me explain, just like muscle tissue weighs more than fatty tissue, not all cells in the body consume energy, metabolize calories, at the same rate. Let’s start with a simple look and then we’ll add more detail. Muscle cells are more “active” than fat cells and consume energy at a higher rate, even at rest.
Your Resting Metabolic Rate (RMR) is the base amount of calories consumed by the functions of the body on a daily basis. These functions include no other activity like exercise or walking. In order to lose weight, you have to have a deficit of calories. You have to burn more than you take in. You can find a tool here to get an idea of what your RMR is.
This can be done a couple of different ways. You can go the diet only route which means eating less calories than your body needs on a daily basis. The bad news with this option is that your body does not discriminate when it comes to making up the difference in calories. It will burn both fat and muscle for energy.
The trap that develops here is that most people start a diet with the mindset that it’s temporary. In the back of their mind they feel that as soon as they get to their goal weight, they’ll go back to enjoying the foods they are currently giving up. By losing both fat and muscle tissue, they may actually have a lower RMR after the weight is gone than they had before they started. If those people go back to eating the way they were before, they’ll quickly gain the weight back, hence the “Yo-Yo” effect countless people have encountered.
With the exercise option, you are adding activity to increase the calorie deficit. Depending on what your exercise consists of, you can still fall into the trap of the diet only option.
The other option is to have a combination of a meal plan (a method of eating healthy that is not temporary and will help you lose weight without feeling like you are sacrificing) and exercise which includes some level of weight training, exercise to add muscle. Now, when I say add muscle, I don’t mean get bulky. I talk of adding lean muscle. Lean muscle may weigh more than fat, but it is not as bulky. Also as you burn that fatty tissue and add muscle in its place, you can increase your Resting Metabolic Rate.
If you’ve never done any kind of weight training before, I wouldn’t recommend hastily picking up weights and doing some form of exercise. That’s how you injure yourself and do more harm than good. Do research and find the types of exercises that will help you. Start with a weight that is right. Randomly picking a weight or one that is recommended by a friend is not a good idea. It may be a good idea for you to pick something lighter and see how your body responds. Lean muscle is built through less weight and more reps. If you do less reps with more weight, you’ll get bulky.
The one thing I’ve learned over the years is this process takes more than just effort, it takes time. Getting fit and staying fit is a journey, not a destination.
