Hello everyone. I'm a newbie here, just purchased a Trek 7100(haven't had it out because its snowing again in Michigan). I need to get fit, lose weight(40#) - 50 yrs old and have a permanent knee injury. I just started Weight Watchers on my own. My questions how many of you eat the so called energy bars/protein bars and which ones are good? And do you eat them as a meal replacement or a snack in between meals. Its been so long since I've been doing any kind of serious training/work out(back in the 80s/90s I was a jogger and cyclist - but not much the last 10 yrs). Thanks.
