Was almost 1 month with no weight lost and I am only 7 weeks out. After reading lots of material I tried increasing my calories to around 800-900 and the weight is coming off. Down 5 pounds in 5 days. I think when we are only eating 500-600 calories a day and exercising the body is in starvation mode. I am exercising at least 5 days per week (10,000 steps) and eating 5-6 small meals a day. Mostly protein and vegetables very little carbs.
