Diane, I don't really have a sweet tooth, either.
One day out of a month I might crave chocolate OR ice cream, but that's about it for me.
What I really liked about the Weight Watchers point system was that you calculate your points, and then you can plan your meals / snacks according to the points that you are allowed.
For example, with my weight, height and a few other factors, I was allowed 23 points a day. (Men get more points than women just for being men.

)
You are also allowed 35 "bonus" points a week.
When I first started it, that didn't seem like much. I initially tried dividing the bonus points up into each day of the week, allowing myself 30 points a day, but eventually realized I would rather save all those bonus points and bathe in pasta or pizza once a week!
But let me give an example of what I was able to eat with those 23 points a day...
Mid morning:
fat free yogurt (1 pt)
medium sized banana (2 pts)
Lunch:
sliced smoked turkey on WW bread with lettuce & mayo (4 pts)
1/4 cantaloupe (1 pt)
Snack:
1 cup fresh pineapple (1 pt)
fat free yogurt (1 pt)
Dinner:
BLT made with WW bread and 3 slices Canadian Bacon (5 pts)
baked seasoned potato wedges -small serving (3 pts)
Snack:
7 points left...That would buy me an ice cream cone (some brands) or lots of fruit!
The biggest problem I had was getting my dairy. Most dairy products cost alot of points, so I really struggled with that.
Most raw veggies are free, so you can munch on them all day long. And there are lots of great recipes for this diet that have portion servings of 8 points or less.
But it's all about the portion sizes as well as the choices that you make, and I will admit it's really hard initially, but once you figure out how to spread it out and start to see results, it's alot easier.
My daughter and son in law are doing the low carb diet right now. Besides the fact that pasta, bread and potatoes are three of my favourite things in the world, I worry that it's not healthy for them.
Have any of you tried that diet?
