Keto is a lifestyle, not a diet. It isn't for everyone but it is for me and supported by my GP and my Oncologist. Any lifestyle change should be medically supported for that individual.
It sure has helped me in many many ways. I will never change the way I eat as it is good for me and I feel fabulous because of it. I use to eat this way up until i turned 40. I didn't know that they way I was eating was known as keto or Paleo or Atkins. Then I got lazy and boom weight gain. Now if I went back to old habits of course I would gain weight again. I wasn't eating right for me or the health issues I have and now I am.
I have received many wonderful comments about my body changes and also some comments like 'oh will you stop loosing weight' or ' if you change you will gain weight' or ' my dr doesn't agree with keto' .
Of course most dr won't agree unless they are more progressive and as for other comments, I just see they have a little envy. Yes it requires discipline and dedication but everything worthwhile requires effort.
The point is doing nothing is not an option if you want to change your weight but what you do must be right for you and as we know we are all different.
