Will yoga exercise benefit weightloss?

If I want to "kill 2 birds with one stone" (to save money), in trying to promote yoga as well as weightloss to my daughter-in-law, what is the best
thing or program to start off with. I have looked at this double- wammy program and it looks good but I need some advice,Can this help? I shows quite a lot of extra off-takes........[YOGABURN]
