Is consuming 920 calories a day ok? I'm trying to lose weight by exercising & counting calories. I'm 140 lbs, ideal weight is my prebaby weight of 122

Many more ?s. It is possible to eat around 1, 000 cal per day to loose weight. The trick is getting the proper nutrition and vitamins into that constrained calorie count. I would also say that exercise at that calorie level would need to be temporarily halved or stopped, depending on what you are doing and how intense the workout is. A better approach may be a few more calories with moderate exercise.
