Is there really a shortcut to Ketosis?

Hey everyone. So I've been meaning to ask this for a while.

I've seen a bunch of supplements that claim to induce ketosis, and I was wondering if any of them were true? I've tried the diet before and loved the way I looked when I was on it, but since I got off, I now have trouble swinging back in.

So yeah, that's why I was wondering if any of these actually work. I found this supplement reviewed on supplementreviews.com and not a lot of people have actually tried it so there's like three reviews on it

Is anybody here doing the same diet? Has anyone tried supplements like this, or anything that might really work?

Thanks in advance guys.
