Well - it might help. I mean, the protein and fats in chicken are different than the protein and fats in fish...so the end result is that your body has to work at it a little differently. Same holds true for say leafy greens vs broccoli all the time. Or quinoa vs oats, or goats milk vs cows milk . It may not be enough of a change to matter, but it certainly can't hurt - and the variety might do your body good. Also, I assume that you are measuring everything? I do know of quite a few women who got 'stuck' and found out through measuring that they'd let their calories/portions creep up.

I assume that your weight routine is predetermined by your trainer, right? Have you asked them their opinion? Honestly, for me, changing up my weight training was the best way to shake plateaus but I figured that wasn't an option with your current routine.

And 'hi' back! I'm glad to see you still here - perhaps we'll get a chance to finally meet and ride together next summer??
