I agree with Diving Biker. Those people that are telling you to stop eating while exercising don't have a clue. Ignore them.

As alot of people here know, I've been very successful on WW. I always eat my activity points, and I eat them on the day I earn them. If you do not fuel your body, you will not be successful at sustaining exercise for any long/intense period at one time.

That said, energy bars can be quite high cal. Don't OVERindulge on them. Make sure you calculate the points in the bar, and be sure to factor them in to the day's training plan. I usually have a good idea of how many points I will earn on my ride. I plan out the food I will eat on the ride and bring it along, so I ensure that my blood sugar stays relatively constant. If I still find myself hungry, well then I find something else to eat at a store and add in on to my tracker later. That's what we have the extra 35 weekly points for.

You might try to find a WW group that has a larger proportion of active women in it. Or see if you can get a knowledgeable leader to be willing to start one.

Best of luck,

Susan
