I also agree with this. If you change your eating habits into a healthier one, you will not just benefit from losing weight but also, this habit can make your body healthier inside and out.
If you start your day with the right food to eat, you'll be energized and you can do much better with work or with just about anything.

Be sure that you're taking more of fruits and vegetables. Drinking at least 8 glasses everyday is also considered as a great eating habit rule.
