Well, having it announced by the physician I was diabetic was motivation, but the answer has become painless: Eat proper food our bodies are designed for. Then you are not hungry between meals. And brush and floss your teeth afterwards, that much work gives one motivation to not mess it up by eating again.
Watch Dr Furman's "Immune Solution" on PBS or read the book. Actually the diet he is reccommending corresponds well to what my grandparents ate when they had access to the neighbors garden, could garden freely on coal company land, but didn't have much money. Not much meat, not much animal fat, not much sugar, plenty of bulky vegetables to fill the stomach. Modern food science says the body is more satisfied with cruciform vegetables (cabbage, brussel spouts, bok choy, kale, etc) than iceberg lettuce, for example. Plenty of nuts and berries, that is something else my grandparents had no access to except blackberries by the sideof the road.
For beans of his diet, I do peanut butter & jelly sandwiches on low sugar bread, with sugar free jelly, and low sugar peanut butter, crunchy. That sandwich is a real filler upper twice a day.
And chocolate without the sugar. I make choco-tacos out of sugar free cocoa, olivio margerine, aspertame sugar substitue, and a little sugar free maple syrup for lasting flavor. Delicious, and all that vegetable fat has pulled down my chloresterol and tri-gliceride levels.
I did the sugar free/more vegetable fat/more bulk/less animal fat diet before I heard of Dr. Furman, but his program confirms the good results I have been getting on weight, A1C, chloresterol, triglicerides, heart rate, and less craving.
Drop all sugar, it just causes craving and shaking if you don't get it. I'm down to 4-5 grams of sugar a meal by looking at the labels. Diet sodas are great compared to vile old Tab with the saccarine, and malitol and sorbitol sugar alcohols seem to satisfy my sweet tooth with one piece of sugar free candy, without the huge craving when I run out of blood sugar. Also, my A1C is under control now, no pills for diabetes in the last two years and I've lost 30 lb.
And aerobic exercise helps you bring your body into its natural state, make you tired at night, not in the day, and stop the cravings with endomorphine. Read Dr Cooper's aerobics books, check with your physician about your heart, then start walking swimming, bicycling, calesthentics, or polka dancing. Heart rate up to .67*(200-age) if I read the book right, for 30 minutes a day.
It is a great life when you feel better.
