I first joined tudiabetes looking for an answer to the same question you have asked – you might find some additional ideas in previous posts. I’m similar to you – I’m 42 and I was diagnosed with type 1 at 35. I was always very active (marathon runner) and a very healthy eater (vegetarian), and I still am. But after I had my second baby (at age 38), not only did I never loose that last 10 pounds or so, but I gradually started to gain more weight, about 3-5 pounds/year. This year, when my clothes stopped fitting, I knew I had to loose the weight. So I tried all the standard things – I ate less and exercised more, but nothing happened. After a whole month of really trying hard to loose weight, I had actually gained another 2 pounds! So, I understand the frustration.
Anyway, after reading posts on this site, I found something that worked for me. I’ve lost 23 pounds since January, and I only need to loose about 2 more pounds. As someone else already mentioned, the real key is to take less insulin. You can definitely do this without letting your sugars go high. The way I did it, was by exercising A LOT throughout the day and using the exercise in place of part of my meal boluses. I run for 30 minutes in the morning (before my boys wake up), then I go for a power walk/stair climb after lunch at work, and then I do wii-fit yoga and strength training everynight after dinner. All together, it’s about 90-120 minutes of exercise. I also had to reduce my carb intake, from 45 to 25 g/meal (but you’re already low on carbs, I see). And, importantly, with all this exercise, I was able to reduce all my basal levels throughout the day, too. My total daily dose of insulin went from 35 units/day to 20-24 units/day. I learned how to substitute exercise for insulin from the Walsh “Pumping Insulin” book chapter on ExCarbs. The main thing I was doing wrong before was eating carbs to cover the exercise (to prevent lows), whereas now I exercise to cover the carbs I eat. I have been able to loose about 2 pounds per week by doing this.
Anyway, I feel great (lots of energy) and my endocrinologist is really happy because my A1C went down. My sugars are a lot better now, even with a lot less insulin. I told my endo what I was doing (after the fact) and I said, “I found that it’s really really hard to loose weight on a pump”, and he agreed with me completely and emphatically. He said this is the only way.
