hea vijay,
other than motivation, profession advice would also have various other benefit , like for eg.. you can lose weight in the first one or two months following the same pattern but after that no matter how religiously u follow that same pattern, much benefits will not be seen as the body gets use to it , n by then it becomes just a regular thing .. hence diet needs to be changed at various level which can be done well under a professional ..
the lipid profile changes around evry 3- months .. so its best to get it redone .. specially if hyper-lipidemia or diabetes is a hereditary problem. and what about the thyroid ? did you get the test done?
my suggestion to you is , whether ayurvedic or alopathic, its best to try first in a natural way .. coz generally when we firmly decide to lose weight , we try to imply every thing possible and every thing we know in that one attempt .. and as a result the entire scedule becomes so hectic tht you would not be able to sustain it for more days .. hence use one tric at a time. whn that tric doesnt seemto work , then introduce a new one .. i think just diet and exercise will work wonders ...
all the best !!
