At what point do I worry about calorie deficit?

[QueenOfTheTamazons 634]

I started working out by taking aqua aerobics classes. At what point do I change my diet due to the additional caloric expenditure? My typical intake is 900-1100 calories and 80-90g Protein a day. I have lost 100lbs in 5 months with no exercise other than daily life activities.

Yesterday I did a 60 min class and 15 mins of "swimming" laps. My ability to actually swim is a step above doggy paddle. Acording to sparkpeople that was 700cals burned. My intake yesterday was 1025cals and 77g protein. I know, in general, you are not supposed to eat back the cals burned while exercising but most people don't eat as few calories as a post op does. 300 net cals doesn't seem like enough but I have frequent stalls.

At what point should I try to increase my intake? The plan is to try and take one of these aqua classes at least 5x a week.

on days you workout you should plan to up your calorie intake. And days you don't, eat the calories you need to maintain or need a slight loss (if you still need to lose weight) your calorie intake now isn't meant for long term unless you're 4'2 and 80lbs. Check out these calculators:
