Thats 70% of what you consume
Only beverage that should go in your body is water.
Stay away from high sugary food(anything above 14 g's of sugar)
Eat more fruits and vegetables.
Turkey/swiss sandwhiches, egg white roll with swiss cheese on a spniach wrap, tuna fish sandwich...lipton soup, all variety's of seafood. Chicken is awesome. Eat like a boxing champion.
Stay away from fried food.
If you can control this, you will be 70% there.
The rest is maintaing exercise cardio and body training.
Get a jumprope and learn how to, if you need help just ask me.
Do 20-30 minutes of high intensity intervals.
3 minute warm up
Cycle 1 is a 2 minutes a moderate pace(60% of your max effort), then 30 seconds at high intensity(90% of you max effort) pace, then 30 seconds at a low intensity pace.(40% of your max effort)
Cycle 2-6 is a 1 minute at moderate pace, 30 seconds at high intensity pace, then 30 seconds at a low intensity pace.
You could do this with jumproping, on the bike @ your local gym or on the treadmill by increasing the speed levels...or just running outside which can be difficult and I don't recommend.
Lastly, core exercises.
6 pack is more about cardio and what you eat. If you consume less calories than you burn, your body fat will decrease progressively.
Sometimes people ignore this, and think doing 300 crunches will turn their fat into a 6 pack.
The only thing that does is make their stomach bigger (adding more bulk and muscle along with the fat)...not really pretty.
I suggest for you to utilize the plank exercise. Followed by a series of bicycle crunches and various twisting exercises.

Just don't over do it in one day, its all about maintain and making sure you do it atleast 5 times a week.
Core training is very important, alot of people like to work out their upper body and lower body, but what connects the two? The core. This should be trained every day.
