I’d go back and reread @David_Stilley and @Regina posts. They have explained keto very well.
When I started keto (Feb. 2019), I ate three good sized meals a day, even though I never had before prior to that. I did not snack in between meals and only drank water or one cup of coffee per day. Although I wasn’t “hungry” for my next meal, per se, it wasn’t like I was stuffed to the gills and too full to eat. This time around, I believed what people reported and fed my body to heal it.
I thoroughly enjoyed the rich, delicious food, and the versatility of what I could eat - and actually being allowed to eat! I looked forward to every meal. This alleviated any hunger and cravings for eating off plan and kept me satisfied for almost a year now (can’t say that about any other diet I was on - the most I could sustain with that was about 3-4 miserable months). After about 4-6 weeks of this and after my body and metabolism had adjusted, I naturally morphed to eating two meals a day and now one mainly, with 48 hour fasting once a week. I became “fat adapted” in approx. 4.5 months. I lost weight right from the beginning and felt physically better than I had since my youth. I have lost 60 of 80 lbs in 11 months, all the while eating. I stay off the scale except when I go to the doctor’s and never measured ketones or anything else.
My husband, who has always been thin in good shape, has eaten keto now, too, for the past nine months and loves it. Even though he has been committed to weight lifting and working out for over forty years, even he lost approx. 15 lbs. of stubborn belly weight which he couldn’t drop before. We often marvel to each other, “Do you believe we can eat like this?!”
Look at this as a marathon and not a sprint. It is a healthier way of eating, overall. Dietdoctor.com is a great source of scientific information, in layman’s terms, that may take some of the mystery out of it.
