This is what I have learned I think:
Intermittent fasting for as long as possible is the best way to tackle diabetes along with exercise and changing diet.
Eat nothing, i.e. nothing but water and herbal tea after 6 pm , and try to leave 16 hours before eating again, 18 if you can.
Cut out bread, pasta, potatoes, rice, oats altogether.
Cut out alcohol altogether, it's sugar in liquid form.
Try to stick to veg that grow above ground.
Eat lots and lots of veg with every meal, before any carbs. Eat protein with every meal, i.e. meat, fish, cheese, yoghurt (Greek yoghurt), nuts in small quantities.
Don't eat fruit alone, only at the end of a meal or with yogurt , avoid melon, mango, grapes. Eat apples in moderation at the end of a meal. Don't eat bananas. Berries are best.
Exercise after meals if possible to burn off excess glycogen.
Do exercise that builds muscle as muscle burns off glycogen. So weights, body pump etc.
Don't snack. Either eat two meals a day, or three, but don't eat in between.
Cider vinegar may help . One tablespoon in water before a meal once a day. Use CD with the mother and make sure it is raw and unfiltered, as well as organic.
Exercise everyday and try to keep as active as possible generally. Don't sit around for long, keep moving. Even vigorous hoovering is helpful. We aren't designed to sit and lie around as a species.
Wear a Continuous Glucose Monitor for two weeks to see what spikes blood sugar for YOU. Everyone is different.
