Ice Bath Calorie Paradox: new Study Reveals Unexpected Appetite Surge
coventry, Uk (Ap) – Ice baths, ofen embraced for thier purported ability to torch calories, may come with an unexpected twist. A recent study conducted by researchers at Coventry University indicates that while cold-water plunges do increase energy expenditure, they might simultaneously trigger an increase in appetite, potentially undermining weight loss efforts.
The After-Drop Effect: Why You Might Crave More Food
Researchers posit that the phenomenon driving this increased appetite is the “after-drop.” This refers to the continued decline in core body temperature even after an individual exits the cold water. The brain regions responsible for monitoring both body temperature and energy levels may interpret this temperature drop as a signal for increased food intake, initiating a natural survival response. This finding challenges the assumption that ice baths are a straightforward path to weight loss.
Study Details: Cold Water vs. Warm water
Professor David Broom and Phd Student Marie Grigg, from Coventry University’s Research Center for Physical activity, Sport and exercise Sciences (Pases), spearheaded the research. They investigated the effects of cold-water immersion on appetite and food consumption. Fifteen active and healthy adults participated in the study, each undergoing three separate conditions: immersion in cold water (16°C), immersion in warm water (35°C), and sitting in a room at normal temperature (26°C). Each condition lasted 30 minutes.
The results revealed that participants consumed approximately 240 more calories following the cold-water immersion compared to the other two conditions. Interestingly, participants didn’t consciously perceive an increase in hunger; they simply ate more.
Ice baths and cold dips have become really popular; with many people hoping they’ll help with weight loss. But our findings show that while cold water does make your body work harder and burn more energy, it also leads to eating more afterward – possibly undoing the potential weight loss benefits.
Interestingly, people didn’t say they felt hungrier during or after the cold water – they just ate more.

Navigating Post-Dip Cravings
While cold-water immersion offers various health benefits, including reducing exercise-induced muscle damage and improving overall well-being, awareness of potential post-dip cravings is crucial, especially for those managing their weight. One strategy might be to anticipate the increased appetite and have healthy snacks readily available after the ice bath.
Our findings show it is important to put strategies in place to avoid over-eating after cold water immersion. More research is needed on the after-drop phenomenon and its role in appetite regulation and whether repeated bouts of cold-water immersion can lead to weight gain in the longer-term which has not yet been tested.

The Bigger Picture: Long-Term Effects and Further Research
The study underscores the importance of understanding the complex interplay between cold-water immersion, energy expenditure, and appetite regulation. Further research is necessary to fully elucidate the long-term effects of repeated cold-water immersion on weight management. Specifically, scientists are keen to understand if consistent exposure could lead to weight gain due to sustained increases in post-immersion food intake.
Do you think the mental benefits of ice baths outweigh the potential for increased appetite? How do you manage your diet around intense activities like cold-water immersion?
The Science Beyond the Chill: Understanding Calorie Burn
It’s essential to recognize that individual responses to cold-water immersion can vary significantly. Factors such as body composition, metabolic rate, and acclimatization to cold can influence both calorie expenditure and appetite. While ice baths do expend energy, a comprehensive approach to weight management should incorporate balanced nutrition, regular exercise, and personalized strategies for appetite control.
The Role of Brown Fat
Recent research highlights the role of brown adipose tissue (Bat), or brown fat, in cold-induced thermogenesis. Brown fat burns calories to generate heat, and exposure to cold can activate this process. However, the amount of brown fat varies among individuals, impacting the overall calorie-burning effect.
Comparing calorie Burn Methods
| Method | Estimated Calorie Burn (per 30 minutes) | Considerations |
|---|---|---|
| Ice Bath | 50-150 calories (estimated, varies greatly) | may stimulate appetite; individual differences |
| Moderate Exercise (e.g., brisk walking) | 100-200 calories | Enduring, promotes overall health |
| High-Intensity Interval Training (Hiit) | 200-400 calories | Effective, but may not be suitable for everyone |
it’s important to note that these are estimates, and actual calorie expenditure depends on a variety of factors.
Frequently Asked Questions About Ice Baths and Calorie Intake
- Do Ice Baths Actually Help Burn Calories?
- Why Might I Feel Hungry After an Ice Bath?
- How Many Extra Calories Do People Eat After Cold Water Immersion?
- How Can I Avoid Overeating After Ice Baths?
- What Type of Research is Being Done On Cold Water Immersion and appetite?
- What are Other Benefits of Cold Exposure Besides Calorie Burning?
Yes, ice baths increase your body’s energy expenditure as it works to maintain its core temperature. However, recent studies suggest that they may also stimulate your appetite.
The “after-drop” effect occurs when your body temperature continues to fall after you get out of the cold water. this triggers hunger signals in the brain.
A study showed that participants ate roughly 240 extra calories after 30 minutes of cold-water immersion when compared to those in warm water or at room temperature.
Being mindful of potential post-dip cravings and planning healthy snacks can help manage your calorie intake.
Researchers are investigating the ‘after-drop’ phenomenon and its impact on appetite regulation, as well as longer-term effects of cold-water immersion on weight gain.
Cold exposure, which includes ice baths, reduces exercise-induced muscle damage and improves overall well-being.
