Fuel 01 · The old way
Glucose
Quick to burn, quick to crash. Constant sugar keeps insulin high, stores fat, and leaves your brain foggy between meals.

Your body runs on two fuels. Learn to switch from sugar to fat, measure the change, and make it stick — one ketone at a time.
The cellular engine
Two fuels. One switch.
Feed your cells sugar and they burn glucose. Take the sugar away and — within days — your liver makes ketones, a cleaner fuel your mitochondria prefer.
Fuel 02 · The fix
Ketones
A cleaner, longer-burning fuel made from fat. Lower insulin, steadier energy, less inflammation, and a brain that comes back online.
-
Flip the switch
Cut the sugar and starch so your body turns to fat and your liver starts making ketones.
-
Measure your ratio
Track blood glucose and ketones, then divide them for your Dr. Boz Ratio. Watch it fall.
-
Make it consistent
Build the habits — and lean on the community — that keep you in ketosis for life.
Common beginner hurdles
Will I get the “keto flu”?
As your body switches from burning sugar to burning fat, some people feel a few days of fatigue, headache, or irritability — often tied to shifting fluids and electrolytes. Staying hydrated while replenishing sodium, potassium, and magnesium helps many people. This is general education, not medical advice — talk with your own clinician if symptoms persist or you have a health condition.
How do I know I'm actually in ketosis?
Measure it. Track your blood glucose and blood ketones, then divide glucose by ketones for your GKI (Glucose-Ketone Index). A GKI under 100 signals early ketosis; lower ratios mean you're deeper in.
What do I eat to start?
Cut the sugar and starch, raise healthy fats, and keep protein moderate. Dr. Boz's Consistently Keto course gives you the exact ranked food choices — the merely acceptable, the better, and the best — so decisions take two seconds at the store.
