Yes it's possible.

I lost 110 in 7 months.

Granted I fell off the wagon gained 30 and I'm just now getting back to the 110 mark but it is possible.

But do yourself a favor, don't go by what the scale says, measure too. I've been up and down the same damn numbers for weeks now and yet I'm getting smaller inches wise.

I think it's my skin catching up from the rapid weight loss but nonetheless, inches matter too so keep track of it.

Good luck and welcome aboard.
