So the answer to the question is yes - it's safe to lose more than two pounds per week... but only if the weight is all fat or at least mostly fat with minimal lean mass losses. If you take example one - with thirty percent lean tissue loss and compound that over a few months, you're talking about a massive muscle tissue loss which can dramatically slow down your metabolism and turn you into nothing more than a "skinny fat person" (a person with low body weight because they lost all their muscle, but still holding stubborn body fat because they slowed down their metabolism). https://fitose.com/vexgen-keto/
