Cryotherapy & Metabolism

Losing weight with Cryotherapy: metabolism, brown fat and energy expenditure

Cold is a powerful metabolic stimulus. Three minutes of whole-body Cryotherapy at -110 °C force the body to produce heat – and that takes energy.

What happens in the body

During the cryo session, the skin's blood vessels constrict and the body concentrates warmth in its core. After stepping out, the vessels widen again, circulation runs at full speed and energy expenditure stays elevated for a while. Brown fat tissue is also activated – a tissue type that converts energy directly into heat instead of storing it.

A realistic expectation

A single session doesn't replace a calorie deficit or training. Anyone wanting to lose weight combines cold with exercise and an adjusted diet. The advantage of the cold lies in the interplay: more drive, better sleep, less muscle soreness – exactly the factors that make a change in diet sustainable.

Recommended rhythm

For a noticeable metabolic impulse, 2 to 3 sessions a week over at least four to six weeks have proven effective. Anyone coming regularly gets the best value with the monthly unlimited pass (€349 per month, maximum one session per day); for getting started, the 5-session card (€150, €30 per session) is a better fit.

Thermogenesis: what happens in the body after cryotherapy

Under a strong cold stimulus the body activates heat production (thermogenesis), mainly via brown adipose tissue and a short-term rise in sympathetic activity with noradrenaline release. In whole-body cryotherapy the cold acts for only three minutes and mainly on the skin surface – core temperature barely drops. The direct energy expenditure of a single session is therefore limited. Smaller studies suggest that regular series of sessions may influence metabolic markers, but large long-term trials are still missing.

Requirements and contraindications

Conditions such as untreated high blood pressure, cardiovascular disease or circulatory disorders should be clarified before your first session. We record your health status with a short questionnaire and recommend medical advice if in doubt. Whole-body cryotherapy is not a recognised weight-loss treatment – it can be a complementary stimulus alongside diet and exercise.

  • Activation of brown fat tissue
  • Increased energy expenditure after the session
  • More motivation for sport and exercise
  • Firmer skin through improved circulation
  • Better sleep – important for any diet

Frequently Asked Questions

How many calories does a cryo session burn?

Reliable figures vary widely and depend on body composition and starting point. More important than the single session is the repeated stimulus over several weeks.

When should I schedule the session – before or after training?

For weight loss, the session fits well after training or on training-free days. Right before a strength session it's less useful, because the muscles cool down.

Is cryotherapy a recognised method for losing weight?

No. It can complement diet and exercise, but reliable long-term data are still lacking.

You'll find detailed articles on individual conditions in our guide section.

Context

What can honestly be said about this topic

Cryotherapy (cryo) is not a replacement for medical treatment but an additional stimulus. Put in context: it may influence accompanying symptoms and support recovery, but it replaces neither diagnosis nor therapy.

What counts is the series, not the single application. We therefore suggest looking at a period of several weeks and simply documenting changes – sleep, pain perception and everyday resilience.

  • Complementary

    Cryotherapy (cryo) complements existing treatment, it does not replace it.

  • Think in series

    Look at several weeks instead of judging a single application.
