It has a lot to do with your cardio, water intake and the kind of food you eat.
Here are some things to avoid the next time you go grocery shopping:
- Foods that are High in carbs and low in protein
- Anything containing high fructose corn syrup
- Mexican food.
Here are some things to get:
- Foods that are high in protein and low in carbs
- Fruits and vegetables (not fried or cooked, just raw)
- Foods that have fiber
- A whole lotta water and Gatorade
If you eat right and hydrate properly, the cardio should do the rest. Don't Diet. PLEASE don't diet. You can (and should) eat the same quantity as you did before, just so long as you're eating the right stuff. Starving yourself the way most "diets" recommend is a great way to end up screwing with your immune support system and leaving you more prone to getting sick.
If you start hitting the treadmill, do not start with an 80 minute session no matter what anyone tells you. You have to work your way up to that over a period of time, so set a time for yourself under 80 minutes prior to starting your work out.
Once you start dropping the pounds, after 4 weeks, you can maximize your fitness by adding some more advanced workouts to your routine. Most people opt for Insanity or P90x, but you have to be psychologically ready for that kind of intensity. I prefer "Burst Training." It's basically a high-intensity workout in a very short period of time, done whenever you have free time.
