Whatever has been covered till now -- we have done over four parts of therapeutic sets in yoga -- all invariably also affect the metabolism. Though the poses have been picked for each set for their primary impact on the problem under discussion, they also aid weight loss. So, I suggest you start with those for starters, extending time in each pose, so you can either do several sets or hold each pose for a minute or more. This has to be built up over a four weeks or so. And if you don't lose flab by then, with the 24 poses we have covered so far, then I would be very very surprised! So start now...
