I see this is an advertisement. You can makee all the claims you want, but it has been demonstrated time and time again that weight lose that you are tauting is not safe. The people following such diets will have unwanted effects over time and especially in their old age. You won’t be around for them then I imagine.
Any quick money player can take advantage of people. Organizations like ACSM, ACE, etc. can’t play it fast and loose. They will be around to face the backlash. You can tell yourself it is all good and sleep tight at night. But this is wrong.
