Right. So I just googled this, and it says 1900 calories a day. But I do utilize the 'lose it' app to track food. Mainly to count carbs, so I know how much insulin to take. I'm usually around 1700 or less, so I'm not really sure what else.
One difficult thing is that when my blood sugar gets low, I need to correct it, and I usually drink a glass of orange juice.
A grown man eating at 1700 calories for 60 days is not normal though. If you gotta rough it . Rough it. You could go about it slow and do 2000-2200 depending on energy expenditure.
