I agree that it's neither safe nor reasonable to try to lose that much weight in such a short time.
A healthy diet and reasonable exercise routine will help get the weight off in healthy manner that will take longer, but will help insure that you are able to keep it off over the long term.
We can help you accomplish such a goal.
It is not reasonable, nor safe!
Unless you are either joking, or testing members' intelligence.
What's the rush anyway?
It took along time to put this weight on and it will take even longer to shed it.
Sorry, nobody can help you with this and if anybody does, it is simply irresponsible!!!
A more doable, safer and sustainable plan would be to lose this weight in
a month or even longer.
If you need some advice on this, let me know.
Cheers,
Niko
