yeah chewing gum isn't going to help. Unfortunately the only thing that is going to help is going to the gym and eating healthy.

Stay away from sugars
try to stay away from fats
Try to keep sodium down (will add water weight and too much is unhealthy as hell)
Keep your Carbs down (unless you plan on doing a lot of running)
eat lots of fiber (green veggies)
eat at least your body weight in grams of protein. For instance I weigh 225 I need to eat at least 225 grams of protein. This helps maintain muscle and protein is harder for the body to break down. It takes about twice the amount of energy to break down protein compared to a carb. This is a hard goal to do. I haven't been able to do it. the reason I say it is because the guys I work out with are pretty buff and that's what they say to do. I actually looked this up and big body builders eat at least 2 grams per pound and they eat like every 3 hours.

I eat 1 egg and 1 cup of egg whites and 4 slices of turkey bacon in the morning, 8-ounces of chicken with veggies for lunch and supper. I sometimes throw fish in there instead of chicken. If you get a sweet tooth go for low fat greek yogurt with fruit added.

If you like to eat sandwiches get the bread with "no sugars" it's better than the low calorie stuff due to a lot of artificial preservatives. And eat turkey or chicken with them. Or get some smuckers natural peanut butter (this is one of the best one's I have found) and put some honey on it. Makes a tasty little sandwich.

Bro, you guys are going about it all wrong! You can't do "exercise" to build up your jaw muscles. You have to lose the body fat or you just have to genetically be born with that kind of prominent bone structure.

Stay away from fats? Do you want to die? You have no idea what you're saying man. You need them for proper hormone function aka Testosterone. SO, if you cut out fat as much as possible, getting a chiseled jawline won't matter because you your sex drive and erection will be non existent.
