I haven't eaten sugar in ten years as it gives me a sugar high and then I crash, even though they have classified me as hypoglycemic (low blood sugar levels). I had a real problem losing weight until I went on a hypoglycemic diet, eating a few small meals per day, then I lost 30 lbs. easily. They said I was putting my body in "starvation mode" prior to that, as I barely ate anything hoping to lose weight, but my cholesterol was above normal then too. I eat a baked potato once a week and fries maybe once a month, so that can't be the problem. Basically, my metabolism is just plain weird and a solution based on my diet other than what I am already doing just isn't going to affect it. Have to go back to the doctor on Friday to discuss the results, guess I'll see what she says.
I'm also hypoglycemic and cutting way down on the fruit and starch cleared me right up. My husband's blood lipid changed like magic.
I'm sorry you didn't have the same experience. Sometimes you really can't fight genetics.
