The Good News: Muscle Never Turns into Fat

Time and time again I overhear someone saying: I used to workout but ever since I stopped, my muscles just turned into fat. Does this happen? Let's set the record straight . . .

Lucky for us, this is not how muscles and fat work. Basically a muscle is a muscle and fat is fat, one can never be the other. Muscles are what moves your body so therefore without muscles, your body would not be able to move at all. Muscles use fat for energy to contract (move your body). This is why the more muscle you build, the more fat that is used up — Don't worry though, this doesn't mean you need to become the Incredible Hulk in order to burn fat, you just need to work your muscles.

Isn't that good news? Now get out there and do some resistance training already.

I think in only EXTREME cases of starvation and lack of food, you start using protein (from your muscles) for energy - but normally you get energy from glucose (carbs and fat).

Cool! I thought that after I quit ballet, all the muscle became fat so I gained a lot of weight. Okay I was only in the seventh grade, so I didn't know much about the body and didn't realise it was because I stopped exercising through ballet that I gained weight.

See, I've been working my @ss off at the gym with a trainer, and have great muscle tone now and I have gotten so much stronger... But, all this muscle is underneath layers of fat :( And yes I do tons of cardio, but I cannot get rid of this exccess FAT!!

this is why weight training is such an important part of working out! The more muscle you gain, the more fat you burn at rest!! :)

Ok - I have a question related to this. If for some reason your body goes into starvation due to lack of food, where does your body get the energy from first, muscle or fat? My guess is muscle, but I'm not sure. And, which burns more fat, resistence training or cardio?
