There is a recent trend where the minute you mention yoga people connect the practice to weight loss. Losing the kilograms of fat, muscle and whatever else is lost when one loses weight- seems to be the prime concern :)
All I can say is, it is a fringe benefit and deserves the importance it should be given and no more.
Of course asana, dhyana, praanayama and all else that comprises the completeness that is yoga work on the body- the annamaya kosha, apart from all other koshas.In the diagram below the five sheaths or koshas surround the being.
Kosha is a sanskrit word for Sheath. Here each kosha refers to a more refined layer of existence and the five layers or koshas are like a map with which we can navigate our inner journey.
1 Annamaya the external physical sheath 2. Pranamaya kosha the vital air sheath
3. Manomaya or the mind sheath 4. Vigyanamaya or the intellect sheath
5. Anandamaya- the Bliss sheath :)
Thus Yoga takes us on a fun journey. A journey from the external to the internal. From the Annamaya Kosha to the Anandamaya Kosha.
While journeying we may and will tighten, lengthen and strengthen muscle tone, align our joints in a better manner, get a sheeny-shiny skin and twinkling eyes, flab may fall away or stay put. One thing we certainly will be doing is getting closer to the Bliss sheath.
Once in the Anandamaya kosha, for a minute, seconds, hours or all the time, our cravings will decrease and so will the need to fill out dents and holes in our psyche with needless amounts and types of food. So all in all there may be a loss of physical weight too apart from the loss of weight from the bundle of stresses, grudges, ego, excessive self-love/loathing that we carry around unbeknownst to us.
