Nick's 24-hour ketone experiment.

4.4 mmol/L in a day: the ketone level a water fast takes about a week to reach.

Nick Norwitz

Nick Norwitz, MD, PhD, combined a ketogenic diet, a 24-hour fast and two servings of Kenetik. Individual results vary.

I used Kenetik. From a formulation standpoint, they use bioidentical D-beta-hydroxybutyrate, which results in higher ketone levels than a ketone salt or something like 1,3-butanediol, and is a heck of a lot tastier and cheaper than a ketone monoester.

Nick Norwitz, MD, PhDStay Curious Metabolism

How Nick ran it.

Pair a ketogenic base with timed Kenetik servings. This is Nick's own protocol, shared for education.

  1. Set your base

    A ketogenic day, around 60 to 80% fat, weighted toward unsaturated fats like olive oil.

  2. Time your servings

    One to two Kenetik Shots, 10 grams of D-BHB each, late in a 24-hour fasting window. Nick took his near the 19- and 23-hour marks.

  3. Hold the habit

    Between protocol days, a daily Kenetik Can keeps ketones in a light range.

Not medical advice. Talk to your doctor before starting a fast.

Not all exogenous ketones are created equal
