Sounds like we need to pray for your brother to control his diet according to the medical advice he has received. That would be very tough - I've said more than once that I am glad, if I had to have a serious illness, that it is lupus and not diabetes. Must be very tough to change so many habits. God bless him, and help him eat what is recommended and to avoid all the foods that got him in trouble. Help him to understand he will lose eyes, kidneys, legs, his life, if he does not comply, Lord, and give him strength, patience, and willingness to do it all. Thank You, Jesus.
