Also, I work out 60 to 70 minutes 6 days a week. Weights on mondays and wed. aerobics on tuesday and thursday. Zumba friday mornings and whenever I can I also go on tuesday evenings and pilates and zumba on saturday mornings.
I went to a dietician and she told me that I needed to eat 1200 calories a day because I was only eating 850 calories a day. I switched my routine. I went to the doctor and got blood work done to check for thyroid problems.
I don't understand what the problem is
I am also a larger, fit person. I finally figured out this past year that I am much poorer at judging portions than I thought! For me, it took finally measuring a few meals by using measuring cups and a scale to see I was grossly underestimating the number of calories I was consuming. The other thing I did was to switch up my exercise routine, using intervals and sometimes, limiting myself to only 30 minutes at the gym every so often so I would really push as hard as possible. It helped me drop about 10 pounds that I hadn't managed to budge in years of countless hours at the gym. Good luck!
