I am shocked at how many calories I used to consume. I wasn't overweight but wanted to tone up and decided to count. I was shocked that I was eating around 8-12,000 a day!!! Now I am at 2800 which is a big difference.
The hard part, as many of you have noted, is trying to eat at a restaurant. The chain either doesn't have calorie info or if they do the number in a dish is outrageous.
