do you know the percentages of fat:protein:carbs you've tried for 'more ketogenic'?
not that i'm encouraging you to make a science out of your meals ... just curious if you have an idea.
I used to weigh everything to the gram, mostly from curiosity, but I never aimed at a particular percentage.
When I want to be "more ketogenic" I just eat extremely low carbs (maybe two pieces of celery the whole day) and make sure there's a lot of fat mixed in with my protein. Sometimes I eat saturated fat by itself, e.g. a piece of tallow.
I guess I never bothered to calculate because whenever I eat this way, my body pretty quickly shifts gears. I can feel when it happens because the feeling of hunger changes and there's a sort of pleasant buzz to the body.
Let me tell you about a friend, since her story is more interesting and sheds more light on this. Her gall bladder was removed so she can't eat very much fat. If she does, she gets sick.
She's been obese since infancy, and she's 5' 5".
Last year she weighed 270 pounds. I convinced her to try an ultra-low carb diet. I was worried that it wouldn't work because she can't eat very much fat. Her diet would have to be mostly protein, and the body can turn protein into glucose.
But within a few weeks her appetite plummeted, an indication that her body had started to rely largely on its stored supplies.
She's been doing this for almost 14 months now. She eats as much as she wants, and that's very little, usually a single small meal or maybe two. On a typical day she'll eat five chicken livers sauteed in two tablespoons of butter and some spinach. That's her upper limit for fat; that amount sometimes makes her a little sick, but she puts up with it. I'm picking this meal because it's probably the most fat she ever eats in one day.
I don't know if she's in ketosis physiologically but pretty clearly she's burning mostly fat since she's lost a lot of weight and she feels stronger and healthier and more energetic than ever, indicating that she isn't sacrificing very much lean tissue. (She's replaced her clothes about five times too!)
Here's how her intake breaks down on that day (again, that's a high-fat day for her):
Total kcal: 716 (she's eating as much as she wants!)
Protein: 79 grams = 44% of kcal
Fat: 42 grams = 53% of kcal
Carb: 22 grams = 3% of kcal
I conclude from this that it's possible (for her, at least) to be in ketosis (or at least burn lots of body fat) when eating as little as 53% of calories as fat.
