I lost 75 lbs 3 years ago. Although I have increased my exercise from twice-a-week Zumba classes to at least five, 1 hour workouts at the gym, I have gained 5-8 pounds. My diet remains sensible: very low fat, limited bread, rice and seldom a potato, lots of vegetables and fruit. In January of 2010, I weighed in at 190.5. By the end of that year, I weighed in at 115. Since October, 2012, I am weighing 120 to 123. I am a 60 year old woman. Any ideas?
