I often wonder if I eat enough. By most standardized calculations, I'm underweight. I'm about 70 inches tall, and 145 lbs. I have a small bone frame and about 7% body fat. I'm 27 yrs. old. On an average day, I eat about 2500 calories, but there are days when I eat only about 1500 calories. These are mostly carbs.
I have sufficient energy, yet there are days when I'm definitely run down. I work 3rd shift, which is part of my energy problem, since I'm always a bit sleep deprived. I often eat at irregular intervals. My appetitie isn't huge, but I have periods of hypoglycemia and severe hunger if I go for too long without eating.
I started cycling this summer, and have been at it now for about 2 months. I feel great when I go out and bike for a few hours, and it definitely improves my appetite. I usually get to go out 3-4 times a week and bike for 1-2 hours. My appetite is improving, but I'm still worried I'm not getting enough food.
I guess I should only be worried if I start losing weight or energy, right?
