my current plan doesn't actually count calories but the do figures it is between 1000 and 1100 per day

I shoot for 1800 calories and I’m trying to add more water and protein to my diet

1200 is for me and each weekend if I want a little more I may have a treat. Only on the weekend.

I am not sure, I have been back and forth. Some days eat more than 1600 and some days less than 1200. I think it depends upon you.
