How do you lower blood sugars?

My husband is a diabetic and his sugars run between 280 and up what can he do to get it to go down,he’s on insulin,pills for diabetics
he doesn’t eat all that much 4 small meals and he just kinda picks at them.He drinks diet tonic or water.
Are there any proven foods that can lower the blood sugars. Thanks any help is greatful needed.

How can I control my weight if exercise doesn’t do it and I can’t stay any diet program for too long?

G O asked:

My height is 1.92m and I weigh in 124kg. Because I’m a diabetic I can’t follow any diet which highly restricts carbohydrate diet. Instead, I have attempted to follow several low-fat and low-sugar diets, but without success. I do a weights program three times most weeks and cycle intensely for two hour bursts.  I’d appreciate any advice.

What are the chances of me getting diabetes?

Chris asked:

I was wondering what the chances of me are of getting diabetes. My grand mom has diabetes(well I think she does she has a machine to check her blood sugar but i never saw her inject herself with insolen) and both of her sisters sons also have diabetes. I think there are about 1 or 2 more people who have it but I cant think of them.

Also does your diet have any effect on wether you can get diabetes or not and how often should I get checked for it?
