I lost weight years ago - 80 pounds to be exact. I went to see a sports nutritionist that said with me burning on average 800-1000 calories a day (I was a workout queen) that I should eat only 1200 calories. Looking back, I realize I was only giving my body 200 to 400 calories a day to live on. I slowly increased my calories to about 1500 a day, still way too little. I went through a stressful time and cut back on my exercise and my diet didn't change much but the weight crept up. Add an underactive thyroid that has been undiagnosed for years and you come up with a very bad math problem.
I realized I destroyed my metabolism and the "sports nutritionist" had absolutely no idea what she was talking about having me eat so few calories. After much research and trial and error...hard work and finally getting the underactive thyroid diagnosed - the weight is finally coming off again. And this time I'm not focusing on the scale. The jeans I have on today are quite baggy on me now. I'm feeling great - oh and by the way I'm eating 1900 - 2100 calories a day doing it!
