Keto made easy

Keto for MMA, Kickboxing and Combat Sports

Quick answer: You can train combat sports on keto, and plenty of people do. Steady technical work and an hour of kickboxing class are manageable. Explosive, all-out work is where keto is weakest, because those efforts run on stored carbohydrate. KetoDick trains MMA and kickboxing on keto, says he'd add carbs back for a fight camp, and describes small carb doses around hard sessions (videos cTGYIFOTPl8, XhEJ9x5sP0g).

Why explosive work is different

Your body has two main fuel tanks. Fat is huge but slow to tap. Glycogen, stored carbohydrate in muscle and liver, is small but fast. Low-intensity work can run mostly on fat. A flurry of punches, a scramble on the mat, or a sprint at the end of a round leans on the fast tank.

On keto your glycogen stores run lower. So the steady parts of training feel fine, and the hardest 30 seconds can feel flat. KetoDick says explosive sports simply aren't keto's strength (video -dHjt_Bpruk).

What KetoDick found in his own training

This is one of the topics where he talks from his own gym time.

He trains MMA and has done kickboxing on keto. In one video he says he's kept his energy up through an hour or more of kickboxing without adding carbs (video XhEJ9x5sP0g). In his long beginner Q&A he's more candid: he does gas out in class sometimes, and he treats it as practice. He uses footwork and range, throws fewer punches, and tries not to let his partner see he's tired (video cTGYIFOTPl8).

He's also clear about the line. If he were in fight-camp week, he says, he'd put some carbs back, and he thinks he'd need them for optimal performance; right now he's just keeping his skills up (video cTGYIFOTPl8). He uses MMA as an example elsewhere too: there's a risk of head injury, but there's also a risk of being fat, so every choice is a trade-off (video 1m1hPgaRIg4).

One more thing from his own story: he says the scale was a poor metric for him partly because of MMA training (video cTGYIFOTPl8). If you train hard, use the tape and photos alongside the scale.

First question: does it matter for you?

KetoDick's first move is to ask whether the lost punch actually matters to your goals (video XhEJ9x5sP0g).

He lists wrestlers, track athletes, sport camps and frequent basketball players as the cases where he'd try it (video XhEJ9x5sP0g). For weight-loss keto with walking, jogging, the elliptical or light resistance work, he says it's not needed.

How he'd dose carbs around training

The amounts he describes are small. That's the point: enough to top up the fast tank, not enough to undo the diet.

So what you do, if you're in the "it matters" group, is test it in training, never for the first time on fight night (video XhEJ9x5sP0g):

  1. One to two hours before: slower carbs, like starches or crackers.
  2. About 30 minutes before: fast carbs, like a sports drink or honey.
  3. After: some carbs in the 30 to 90 minutes after training, up to two hours, for recovery.
  4. Amounts: about 10 to 20 g before and 10 to 20 g after. Start near 10 and adjust.

In another video he gives a bigger range for weekend competitors: about 20 to 50 g of carbs two hours before and about 20 g after (video f119qGyJ7AY). Treat the smaller numbers as a starting point and the larger as an upper bound you work up to.

He also says only people carrying far more muscle than usual are likely to need carbs around training at all (video uXzscHudgt0).

Tired in class? Check electrolytes first

Before you blame low carbs, check salt. KetoDick says tiredness from walking or chores on keto is probably electrolytes, not glucose, and that sports drinks and flavour drops contain far less than people think (video -dHjt_Bpruk). Sweaty training makes this worse.

His own routine was a chicken bouillon cube with a quarter teaspoon of potassium-chloride salt, three times a day (video -dHjt_Bpruk). See Electrolytes and Sports drinks on keto.

One firm caution from him: talk to your doctor before taking supplements, because sodium and potassium imbalances can land you in hospital (video 9r2Y74AnjUQ). If you have kidney disease or take blood pressure medication, talk to your doctor before adding potassium salt.

What the research says

The evidence pages on this site don't include trials on keto and combat-sport performance, so they can't settle the carb question for fighters. What they do cover is protein for people who train, which matters more than most people think on keto:

KetoDick's own rule of thumb is about 80 g of protein for women and 100 g for men, plus 20 if you're tall and 20 more for heavy training (video UygKGoP_BtA). For a 70 kg (154 lb) fighter, the ISSN range works out to roughly 98 to 140 g, so his training-day number sits at the low end of it. If you're training hard, the literature points higher.
