Well, first of all, some supplements may have some use in bodybuilding, but they are not healthy to take long term, the ones who benefit the most are the sellers of the product. They are useless and harmful in the long run.
There are much better and faster ways to lose weight, and some things usually require some change in your lifestyle, including your diet and exercise.
Many skinny people have a very high metabolism, which means their body burns fat at a faster rate than someone with a slow metabolism. Having a high metabolism keeps you slim because the food you eat doesn’t turn into fat, it burns into energy and there’s nothing left to turn into fat.
If you have a slow metabolism, you need to speed it up a bit so you can burn fat much faster. This is what you have to do…
First, you have to make sure that you do things differently than the people in the gym who have high metabolisms, you have to exercise, eat and rest differently than they do.
You need to consume more calories throughout the day to speed up your metabolism so you can have more energy and get the nutrients you need to fuel your muscles. The key is to have a good breakfast in the morning, even if you don’t eat anything else, but it is recommended to eat 4 to 6 times a day, but in smaller portions than usual, which will prevent you from going hungry.
The question “how come people lose so much weight without special supplements?” is not the real question here, because weight loss supplements are best left alone. There are other safer and more effective ways to burn fat.
