Day 3 is where plenty of people quit

Day one feels fine, even good. By day 3 there's a headache, not much energy, and a bagel on the counter that keeps calling your name. At 3 pm the soda machine down the hall starts talking too.

Week one of keto can feel like wading through fog. Plenty of people stop right there and read it as a verdict on keto, or on themselves, when part of what's going on has a plain, boring fix.

Keto flu is often a mineral problem

When you cut carbs, your body lets go of more sodium for a while, and water goes with it. Keto researcher Stephen Phinney calls it the natriuresis of fasting, a term from a 1975 paper in the New England Journal of Medicine.

His own first ketogenic study, published in 1980, planned for it from the start: every subject got sodium as bouillon each day, plus potassium. The salt advice most of us start keto with points the other way.

  1. Carbs drop, and sodium leaves with the water.
  2. Plain water has no sodium to give back.
  3. Salt water can work, but nobody tells you how much, and it tastes like the ocean.

Questions before day one

Does Fuel put me in ketosis?

We don't claim that. Cutting carbs is what gets you there, and nobody has measured what one packet does to blood ketones. Fuel is there for the sodium your body sheds at first, and it brings ketones along: BHB is a ketone, the fuel your body makes from fat when carbs run low.†

Why not just salt my water?

You can, and salting your food helps too. Fuel puts sodium, potassium and magnesium in one packet, so there's nothing to measure. Many Americans fall short on magnesium. One packet gives you 30% of the Daily Value. See nutrition information for sodium content.

Is there sugar in it?

Zero sugar, and less than 1 g of carbs per packet, so it's keto-friendly. It's Melonberry flavored and sweetened with Glyvia™ and stevia. See nutrition information for sodium content.

Do 3 packets last 14 days?

No. The 3 packets are there so you can feel the difference. After 14 days it turns into your monthly supply, and you can cancel anytime. Not for you? Cancel before day 14, pay nothing.

I'm watching my sodium. Is Fuel OK for me?

Each packet has 600 mg of sodium. If your doctor has you watching your sodium, if you take medication, or if you're pregnant or nursing, ask your doctor before you start.

Make the switch. Then stay on it.

Day one is yours to pick. Put Fuel in the cupboard before it comes, and the first 3 packets are on us.
