Gee, I guess "long-term" must mean something longer than 3 1/2 years:

Then I drifted upwards over the next year to around 8 lbs below starting weight & stayed there for a year. Then I cut out ice cream for dessert (we couldn't resist giving ourselves bigger & bigger portions over the months!) & my weight drifted back down by 16 lbs (to 23 lbs net below starting weight). I also switched to a canola-based margarine, but recently I couldn't find any and had gone back to regular margarine; that might be why my total cholesterol came down last year but was higher in the last test.
Can't find an argument in those facts.. keep up the fine work, skinny!
Have you considered trying butter instead of margarine? It tastes a lot better, and is better for you. As long as you don't consume it in a high-carbohydrate diet, the saturated fat from butter is a healthy part of a balanced diet (a lot better than the hydrogenated oils used in margarine) and you get healthy amounts of many nutrients (vitamin A, vitamin E, selenium, etc.) as a nice bonus in addition to the better flavor.
