I'm type 2 and I look forward to my outings because I pretty much can eat anything and as much as I want. Hiking and paddling burns through the calories and keeps my blood sugar levels at normal levels with a little help from Metformin. Through trial and error I have learned how many grams of carbs I can consume at certain times of the day and how physical activity affects my blood sugar levels. In general, my levels want to rise throughout the day. Physical activity has a larger impact early in the day vs. later. Thus, I hit the gym in the mornings and gradually taper my carb consumption throughout the day.
In the real world, I am restrict myself to 45 grams of carbs per meal and may consume two snacks of no more than 30 grams each. On the trail or water, I increase my carbs to 90 grams for breakfast, 60 grams for lunch and 45 grams for dinner. My mid-morning and afternoon snacks are 40 grams each. If it is going to be a cold night and I had dinner early, I may have a pseudo bedtime snack of around 30 grams.
Bottom line, everyone reacts differently. You will need to monitor your levels several times throughout the day to learn how you react and what your trends are. I pretty much have it dialed in and tend to monitor myself closely for the first few days to see if I am still responding as expected. If so, I stop testing myself with every meal and fall back to once a day before and after a meal. I do rotate between breakfast, lunch and dinner. When it gets so cold that I have to wear cap and gloves I have found that my glucometer will not turn on unless I keep it on me.
Obviously, my protein consumption does increase and I hit the fat hard to make up for the calorie deficit.
