oh just GIVE ME A BREAK!!!
You're big because you excessively eat. You eat inbetween meals, someone may eat a larger supper than you - but after that you eat little snacks. Little bag of chips, chocolate bar, a second plate of supper, stuff like that is what kills you.
Eat a nice breakfast, a nice lunch, a nice supper (Nice as in not a big 2 plate size bowl of spaghetti) and you'll be fine.
Hell I didn't even exercise much at all and I lost 75 pounds just by eating better foods and not eating between meals.
OH and I didn't blame stupid shit all the time like mcdonalds and facebook. YOU put the food in your mouth, THEY DONT.
People always ALWAYS looking for excuses... its absolutely pathetic. (Its genes, its glandular problems, its facebook, its the tv, its this, that, this, that)
