According to a calorie calculator you need between 2500-2800 calories to sustain your daily work. Really sit down and count your calories over a day and see what you are eating. If you are drinking sodas and eating snacks, they add up fast.
If you eat carbs, you should always have a good protein source (or fat...protein is better) with it. The protein (or fat) will delay the peak glucose levels in your body making it so your body doesnt have as high of an insulin spike. When your body does have an insulin spike to control the blood glucose, the body will start storing fat. This is part of the reason most diabetics are usually overweight. Their body cannot produce enough insulin to stomp down the high glucose level so insulin is supplemented and creates a spike.
Start eating cleaner foods. The tortilla in the burrito is killing you. High amount of crappy carbs. Try eating a cup of oatmeal in the morning. The best thing you can do is eat 6 small meals a day...healthy SMALL meals. This is how I eat everyday:
7am - 1 cup oatmeal w/ 1 cup milk, 2tbsp honey (taste and calories)
9am - Detour protein bar
10am - pre-workout drink (super pump 250)
11am - post-workout protein shake
12:30pm - 1/2 chicken breast (12oz) on 2 slices of multigrain bread w/ ketchup or ranch...something and 1 serving of bagel chips
3pm - smoothie... 4 strawberries, 1/2 cup pineapple, 1 banana, 1tbsp splenda, 2 tbsp honey, 24oz ice, 1/2c milk
5pm - Detour protein bar
7pm - something for dinner...always in a conservative amount
9:30pm - protein shake (evo pro)
Good clean diet and keeps my body from trying to store everything from fat. Im eating right at 2500 cals/day, 200g protein. It sounds like a lot of food and hard to do...but its not. Switch around the meals to when you work out, and take something portable for the snacks while you are at work. Drink lots of water and cut all the sodas (unless you drink diet).
Then biggest part of losing weight... CARDIO. Get your butt on a treadmill, stairmaster, ellipital, or hell, just go out and jog. As gay as it sounds, do tae bo at night. You need something to wear down the calories. Its not healthy to stop eating and not exercise, your body will go into catabolism and start breaking down muscle.
I should have your ab workout dvd out today. Do it 3 times a week. Im going to get you a copy of the other cardio based workouts so you can do those too
