Hey, one big reason *I* chose the DS was because it would change *my* eating habits the least. There's nothing wrong with wanting that.
At 8.5 years post-DS, an average restaurant meal for me is an 8-ounce steak, a small salad (with lots of ham and cheese!), a few bites of a baked potato (with LOTS of butter and sour cream!), a yeast roll, a couple of glasses of iced tea, and a few bites of dessert. Or if we're at a family-style buffet, I'll have that same small salad, a fried chicken wing, some meatloaf, maybe some Salisbury steak or whatever yummy meat they have, a few bites of mac and cheese or mashed potatoes, tea, and dessert.
What you say about walking, counting calories, and seeing a nutritionist yet still being unable to lose weight tells me that you need the sort of metabolic help only the DS can give you, long-term.
Please, feel free to ask any questions you want! Just don't get your feelings hurt if someone smarts off at you---we tend to be a smart-mouthed group. (*grin*)
