Exercise, by itself, is an ineffective weight-loss tool
If any trainer tells you his gadget or workout routine will burn off all the weight you need, you should burn some calories by running away from him. To lose weight and keep it off, you have to pair exercise with a diet plan. In fact, exercise alone leads to a very modest decrease in total body weight: less than 3 percent. What’s worse: For some, exercise alone as a weight loss plan induces more hunger, which can offset what improvements you’ve made.
