I weight about 134 lbs, 5'-6" adn 38 yrs old. I eat for fuel/ performance.. and for taste as well. I am 38 now, and an avid Crossfitter for about 6 years. I have been a Type 1 Diabetic for about 13 years now. Eating on the Zone diet has absolutely improved my performances, recovery, speed, and energy levels.
I eat primarily low glycemic index carbohydrates (mostly vegetables and fruits), lean meats, some nuts (almonds), and I also eat peanut butter for my fats as well. I eat trying to maintain a Zone diet, with about 16-17 blocks per day. I DO eat/ drink plenty of milk and cottage cheese, plain lowfat yogurt ,etc as well as lots of eggs as well. They're great and easy to eat and make.
I would say that normally I eat about 140 - 150 grams of carbohydrates plus or minus. I eat about 120 grams of protein per day... possibly a little more. That's split into 3 meals and 1-2 snacks per day. The good fats keep me from losing weight and keep me satisfied. A lot of people ask how veggies are going to keep you full. I say eat a 2/3 plate of fresh steamed veggies, 6 ozs protein and some nuts and tell me you're not full. Also, I won't be hungry in 2 hours either. I also drink a lot of tea throughout the day. I like tea and it tastes great. My A1C has never been above 6 and is usually lower. My numbers are almost always in the 80-100 range... although I do hang out in the 70-80 range and feel fine... I would bump up my numbers if I was going to drive or be out and about, and I almost always keep a granola bar, or something like that in case I drop for some reason like stress, etc.
best to all diabetics starting to keep track of what they eat. Do it scientifically and you'll reap the control and ease of being able to see what foods effect you in different ways. Also track your exercise and see how that effects your insulin. For me, usually the exercise will usually lower my insulin down a unit or so as it makes the insulin act stronger somehow.
I'm not perfect. I do love ice cream and chocolate, so I do have an occasional cheat meal and snacks. I basically eat well, so I can eat whatever I want to whenever I really want to. I love almost everything I eat so it's not hard at all.
