Dr. Pitts, I am a 5'6" female who weighed on Monday morning at my home scale and weighed 90 lbs. On Wednesday morning, I weighed on a different scale and weighed 95 pounds. On Friday morning, I weighed 97 pounds. I am very confused by this, and don't know what to do about calorie management. I count calories because I feel as though I have no internal hunger sensors anymore. If I don't plan meals and snacks, I will skip them. Please give advice.
