As we age, some of us are more insulin resistant, meaning our body has a tougher time metabolizing carbohydrate, especially if there is a history of high carb intake for years. Those people do better with a lower glycemic index and possibly lower carb intake in their diet. Some people also have a particular issue with wheat containing foods, so you may do better with brown rice or some other grain. This article I linked to below explains it pretty well. I'm 54 and I do better with very little grains and fruits. I make up for it with lots of veggies, beans and occasional sweet potato or starchy squash. I don't remember if your exercising at all, but simply taking a walk a day may be helpful. And drinking lots of water is helpful to many of us. Even if your not losing presently on SB, your body chemistry is changing; glucose metabolism is normalizing, triglycerides dropping, possibly blood pressure lowering. We can't always see the changes but they are a positive effect. Try not to get discouraged. These are things that cannot be measured for a contest. Too bad they can't reward you for staying OP despite no weight loss!
