Notes

1. It says exercising and working out is not always the best way to lose weight. People tend to eat more after they work out because they're tired and they're hungry. It might be best for keeping yourself fit and healthy, but not the best choice when it comes to losing weight. There might be no difference in the weight at all, or even worse.

2. Calories are good ways to keep track of your energy budget. The "ideal" would be to gain and lose the same amount. If we gain more than we burn, then most of it is going to turn to fat and make you gain weight. 10% of the calories are for digestion, 20% is for physical and the rest is for you body to normally consume the energy you need.

3. There are many myths of exercising. One example is that unused musces turn into fat. This is not true. Sean Kuechenmeister said in the video that Muscle tissue has muscle cells and fat tissue has fat cells. These are very different. To be honest, it is IMPOSSIBLE for muscle tissues to turn into fat tissue even unused.
