When I am exercising sometimes I get real weak all of a sudden, almost faint:w00t:. I am trying to lose alot of weight of course (150 lbs) or more. Right now I weigh about 357. I just bought a bike and want to ride ALOT. But, I am afraid of having an "episode":scared2: while I am far from home. I wonder if the problem is a lack of calories. I am eating about 1000 calories per day, per doctors orders. Isn't that too little. Or am I just that out of shape or what. Maybe I just need to continue and it will get better. But I just wanted to get others feedback.

Thanks

Do you eat right before you exercise? Feeling faint can be from low blood sugar but it also can be from pushing yourself too hard and getting your heart rate up too high. Do you have a sense for which it is?

I assume you had an EKG and maybe a cardiac stress test right before surgery so it's not something wrong with your heart, but that's also a possibility. But the others are more likely.

Should I be eating just before I exercise? I usually wait about an hour or so. But, I will look into the blood suger. That is EXACTLY the feeling that I get. Thanks

I try to do it about half an hour before. Too soon and I am bloated. But I just go by how I feel, not by any expert recommendation.
