You choose to drink a 200 calorie beer when you go out to dinner instead of a 1000 calorie margarita (although you desperately want one).
I even went out to dinner. I ordered a grill chicken and avocado sandwich that was most likely still over 1000 calories. It came with the most delicious garlic french fries. The difference was, I also ordered grilled asparagus and ate them first, and instead of gorging myself on with the whole meal I ate only half of it, and took the rest home to finish the following day. I claimed one of them as my cheat day, and the other I had to really be careful about my caloric intake so that I still met my goal of 1200 per day. Since I started, day one I was 149.8, the next day, I was 152 and then 151. After the cheat day I was 151.6 and now I am 149.7. I truly believe that since I am consuming so much less I have lost this weight in pounds of fat off my body. I have not exercised since that four mile bike ride, but I plan to begin walking or bike riding the kids to school on a daily basis to help burn those calories.
