Nutrition is 90% of your workout when it comes to weight loss

Nutrition is the most important aspect when it comes to losing weight. You could do a fantastic workout but if you follow that up with a high caloric, high fat, high glycemic diet you have just blown it as far as weight loss goes. Exercise will give you many benefits. It will help create a deficit in caloric intake, it will strengthen your heart, build muscle, add to your self esteem through your accomplishment, increase oxygen intake, release endorphins, just to name a few.
However, if you want to lose weight you must realize that what goes in your mouth is THE most important aspect of your program.
