Thanks for your reply, Steven.

I really think it depends also on the person. I'm young and sporty. There are some people where it won't work to just walk a bit more every day or eating more vegetables. Yet, the majority's metabolism is reacting to that.

Everything I put into my articles is also practiced by myself. I've spent the last years doing lots of self-experiments and if something worked for me, I find it worth sharing, because there's a chance that it works for many others.
