Type 1 diabetic

Lower carbs is better for us in general, really (though I love bread, so still eat it rather than feel miserable by depriving myself, but I've cut out pasta and a lot of potato and stuff like that). So reduce carbs where you're happy to, and keep an eye on your sugars, as your insulin needs are going to change. If you're exercising, keep some glucotabs or other emergency sugar to hand, because I found I was getting quite a few hypos while I was working out what the reduced food intake and extra activity was doing to my sugars and insulin requirements. If you do have a hypo, don't overdo it by eating more than you need to recover - I used to drink and eat a load of stuff because my body said it was ravenous when I really only needed a glass of juice and a bananananana or slice of bread most of the time. Also don't feel guilty if you end up having to go over your calorie allowance to deal with a hypo, it's just one of those things we have to deal with. You'll learn to adjust quite quickly. Good luck!

One problem we ran into is exercise at night as even with modification to his insulin intake he would keep dropping low. So now his exercise has to take place at least 3-4 hours before bed. So watch late night exercise
