No. Diet is very important. Yeah, you can lose lots of weight by not eating much especially if you are on Lipo 6 Black UC. But those losses would be muscles loss and that's not a good thing.

Well, I might said that unless you get your diet fixed, just forget about your fat burner. If you cannot create a calorie deficit in your diet, you won't achieve your needed result and then will putting the blame on the fat burner. Trust me, I was experimenting with my diet when I consume my fat burner. Without proper diet, it is either you still gaining weight (which is sux), maintain your weight (still sux) or end up losing a lot of weight within first few weeks (this is the suckiest). Why? Because...

p.s: read my link about bmr and fat loss

The diet can only be structured only if you know your macro nutrition breakdown and you calorie intake. If you need 150g of protein per day, you need to consume 150g of protein regarding the sources but whole food is recommended.
