There are a couple ways to kickstart ketone production, if that’s what you’re after. You can increase your intake of medium chain triglycerides, as found in coconut products. Since MCTs don’t show up in cell membranes and never really appear in adipose tissue, they go directly to the liver to be converted into acetyl-CoA for energy. Remember how the acetyl-CoA-ATP pathway can be overwhelmed, thus spurring the creation of ketones? That’s what eating MCTs can do – increase ketone production. Use more coconut oil and fewer long-chain saturated fats (which do go into cell membranes, can show up in adipose tissue, and are less likely to overwhelm the liver’s ability to make ATP), like animals fats, while you get adjusted.
You could also incorporate ketogenic amino acids. Huh? Well, a bit like how certain amino acids are more likely to participate in glucogenesis, certain amino acids are more likely to participate in ketogenesis. Both lysine and leucine are readily converted into ketone bodies. As Paul Jaminet points out, high-leucine ketogenic diets have allowed researchers to treat epileptic patients without having to resort to the overly restrictive traditional ketogenic diets. Doing it this way gives you a little more leeway with your vegetable intake.
