Creatine Calories: Does Creatine Affect Weight Loss?
Pure creatine monohydrate has essentially zero calories. Learn how creatine affects body weight, muscle mass, and fat loss — and what the science says.
Frequently Asked Questions
Does creatine have calories?
Pure creatine monohydrate contains essentially zero calories. A standard 5g serving provides fewer than 20 calories, and most of those come from processing additives rather than creatine itself. For practical purposes, creatine does not meaningfully contribute to your daily calorie intake.
Does creatine make you fat?
No. Research consistently shows that creatine does not increase body fat or fat mass. Any weight gain from creatine is due to water being drawn into muscle cells — not fat accumulation. Studies actually show a small reduction in body fat percentage with creatine plus resistance training.
Can I take creatine while trying to lose weight?
Yes. Creatine does not add meaningful calories and may support fat loss indirectly by preserving lean muscle mass during a calorie deficit. More muscle mass means a higher resting metabolic rate, which supports long-term fat loss.
Does creatine break intermittent fasting?
Pure creatine monohydrate does not break a fast. It contains no calories, does not spike insulin, and has no carbohydrates or sugars. Some flavored or premixed creatine products contain added sweeteners — always check the label if fasting is important to your routine.
How much weight do you gain from creatine?
Most people gain 2–5 pounds in the first one to two weeks of creatine supplementation. This is almost entirely water weight — creatine pulls fluid into muscle cells, causing a temporary increase on the scale. This is not fat gain, and the scale increase typically stabilizes after the initial loading period.
