I have felt really tired and always hungry starting just before I donated blood two weeks ago. I was afraid I was overtraining, so I halved my total workout times from (3+ hours to about 1.5 hours) and took two days completely off. I ate about the same, which is generally when I'm hungry. So why have I been losing weight? I went from 160 to 156 in the past week (the first week I remained at 160). That isn't normal for me when I don't do as much exercise. I come from a family of fat people, and we generally gain lots of weight. The strange thing is that lately I have not been eating very healthy. A chicken burger, french fries, another chicken burger, fruit + yogurt, strawberry 2% milk, and a candy bar. Bad food I know, but that is relatively typical - if anything I usually ate a little healthier but about 33% more. Then why did I still lose weight?
