Yoga and meditation can aid fat loss, but not so much from the physical effect of the movements as from their calming and relaxing effect. Several studies have linked high levels of the stress hormone cortisol to weight gain, particularly in the belly area. Practice yoga for at least 20 to 30 minutes a day for best results or start a daily meditation practice.
In other words, sticking with an exercise regimen can trigger sticking with a healthier diet, but it's best if you don't think of it as a way of burning off calories for the sake of weight loss. So, cultivate an exercise practice you actually enjoy, stick with it, and know that it’s making you healthier, and let it inspire you to make the choices you consider healthy.
Here's something else most people probably don't know: Fidgeting is good for you. It's considered a nonexercise physical activity, and it's an important way to burn energy. You get more health benefits if, in addition to exercising, you are a more fidgety, more active person the rest of the day. This means gesturing while you're talking, tapping your foot, just moving around.
