I've been doing WW for 4 weeks now and have lost 14 pounds. However, you have to be disciplined and really keep track of what you eat. Now, I'm cheating a little bit. I don't actually go to the meetings, I borrowed the books from my mother who followed the program and lost 40 pounds. As a man, sitting in a room that is 95% full of women is a bit intimidating.
Flex points works and in reality you are training yourself to eat healthy. I save up my left over points and go out once a week for a nice dinner and dessert ! I like the fact that I can eat whatever I want and I'm learning to make better food choices. Here some simple tricks I have learned that will help you on this diet.
1. Watch what you drink. I never realized that even though mosts soda and fruit juices are fat-free, they are 100 - 120 calories a glass and will cost you 1-2 points ! Drink water and diet drinks. One exception. Have a small glass of orange juice at breakfast even though it will cost you 1 point for its health value.
2. EAT 3 meals a day ! Do not skip meals, especially breakfast. Breakfast starts your metabolism each day. Don't horde your points for 1 sinle meal.
3. No eating after 9:00pm. Anything you eat before bedtime just turns into fat.
4. Be reasonable when you shop for groceries. 98% Fat-free doesn't mean anything if there is 300 calories per serving. You will find that you might as well buy some of better tasting food over low-fat or non-fat when you see the points are actually the same.
I hope this all helps !
