Hi T.,
I, too, gained weight as I reached my 50's. It is typical of women who are close to menopause to have their metabolism slow down. Insulin resistance is also common and can be totally controlled, in most circumstances by diet. There are very good ways to combat this.
I managed to lose 27 pounds and keep them off by changing my diet and adding a whole food product called Juice Plus. I found that with the Juice Plus capsules (which have 17 dehydrated fruits, vegetables and grains) I was able to let go of my sugar cravings. As you have heard from all the other people who are giving advice, sugar is deadly to your diet. It also depresses your immune system. It is also sneaky. Read the labels of the processed foods and beverages that you may be using. 4 grams of sugar is equal to 1 teaspoon of sugar, so a "diet" protein shake with 28 grams of sugar, really contains 7 teaspoons!!. Many processed foods have a very high amount of sugar and very little nutrition. Cutting out most processed foods is a good idea, also cut out white flour and white rice products as they raise the glycemic index quickly.
I found that if I carried around a snack bag of fresh fruits and vegetables that were ready to eat, I could take care of my food cravings by eating as much of these as I wanted. (It is recommended by Harvard University that we eat 9-13 servings of fresh, raw fruits and vegetables every day! Most of us can't, won't or don't do that.) I would frequently eat two or three types mid morning and another 2 or 3 in the afternoon. My favorites are grapes, mini carrots, bananas, apples, celery, broccoli, and mandarine oranges. Then at a regular meal time, I could have smaller portions and not feel deprived. Low calorie soups and salads are great for the meals. I also started buying only whole grain bread and pasta products. The whole grains must be listed on the label first! I stopped buying foods with trans fats, because they clog up your arteries. Even if it says 0% trans fat, read the ingredients. If hydrogenated or partially hydrogenated fats are listed, they are trans fats. Even a small amount can increase your chanses of a heart problem.
I also used the Juice Plus Thins, which are completely safe wafers that provide fiber and control hunger. They also balance your blood sugar level and keep the metabolism up.
The Complete Juice Plus shake mix is the best one around. It is low in calories and in sugar, and provides soy protein and many dehydrated fruits and vegetables. I used this as a meal replacement and made it into a smoothy with other fruits, juices and soy milk. I still do it every day, because it tastes so good and fills me up, and is quick and easy to do.
I hope these ideas help. I was a yo-yo dieter for years before I found Juice Plus and changed my diet. I went from a size 14 to a size 6-8 in 6 months. Now shopping is fun!
Good luck, and don't give up, or just blame your genes, you can conquer the weight and insulin resistant problems.
