Last summer, I did 20-25 miles per week on the elliptical trainer. I gave up all drinks except green tea and water, and my daily caloric intake was 2000 calories per week. Guess how much I lost that summer? 3 lbs in 2 mos. Is it because I'm too skinny to lose a lot of weight? No. I'm actually 20 lbs over the weight I should be for my height. Is it due to the metabolism I have because of my age? Well, I'm only 25. Is it because I have hypothyroidism? Went to the doctor. EVERYTHING was normal. People tell me there has to be other factors to my problem. I try and I try to figure out what "other" factors theyre talking about, but in most cases I dont agree with them. I once read about a lady that decided to get liposuction because even though she's done 3 triathlons, she still didnt "look" like she was that fit. Could I be one of them??? Is anyone else working hard but barely losing any weight?? I'm really trying to lose weight this summer but last summer was a bad experience for me and not really a motivation for me at all.
