You should do a few things;
1.) Cut out liquid calories altogether. That doesn't mean drink diet soda though, as a can of that every day will give you 3x the chance you'll have a stroke. Stick to water or those little packets of Crystal Light juice mix. Those are only 10 calories a pop so they get rounded off.
2.) Learn to enjoy grilled lean meats like fish, poultry, or very lean hamburger, like 93% or above. Eat a lot of egg whites, as they're not very high calorie foods (like 17 per egg) and leave you feeling full. Cook things on Foreman grills to drain the unnecessary fat out.
3.) Replace all your condiments with hot sauces. They have much less calories and make you feel fuller for the same piece of food.
4.) Stop eating fast food that's not Subway or the grilled chicken sandwich without the sauces or something. It's really just slowly poisoning yourself with chemicals.
I hope you follow at least one of the above pieces of advice. Much as I do shit on you it'd be nice for your daughter if you were alive for her high school graduation, or at least not looking like a photo negative of Lt. Dan.
