If you want to reduce the time you spend in low-carb adaptation, crank up the fat. If you go on a high-protein, moderate-fat diet (Schwatka’s reindeer diet), your body will convert the protein to glucose via gluconeogenesis, so you’ll still have glucose to keep the glucose worker enzymes busy and will prolong the conversion to fat and ketones as your primary energy source.
So Rule Number One to reduce the time spent in low-carb adaptation purgatory is: Don’t be a wuss when you start your low-carb way of eating. Keep the carbs cut to the minimum and load up on the fat. Eat fatty cuts of meat, cooked in butter or lard if you want, and force your body over to using the fats and ketones for energy as nature intended. I mean, don’t try to be noble by eating boneless, skinless chicken breasts – instead insert some pats of butter under the skin of a chicken leg and thigh before cooking, and wolf them with your fingers while the fat drips down your arms. Do not trim the fat from your steaks – eat them from the fat side in.
If you leave anything on your plate, make sure it’s the meat and not the fat. If you don’t already, learn to love bacon, and don’t cook it ‘til the fat is all gone: eat it wobbly.

And whatever you do, for God’s sake, don’t listen to your body during this adaptation period or you’ll never cross the chasm between fat and miserable on your high-carb diet and slim, happy, energetic and low-carb adapted on the other side.
