An icy swim may cut ‘bad’ body fat, but further health benefits unclear

Exercise in general – and cold-water immersion in particular – seems to be good for brown fat, the “good” kind of body fat that actually helps burn calories.

But it’s not clear if this benefit extends to other types of fat, or if it has any meaningful impact on health, according to a new review of the evidence.

Brown fat, or brown adipose tissue, is a type of body fat that’s packed with mitochondria, the powerhouses of the cell.

These mitochondria are very active, burning calories to generate heat. That’s why brown fat is sometimes referred to as “body fat” or “good” body fat.

In contrast, white fat stores calories and has very few mitochondria.

People tend to have more brown fat when they’re young, but it declines with age.

Exercise is one way to increase brown fat, and cold water immersion is thought to be especially effective.

In one small study, for example, people who took an icy bath for two minutes burned an extra 200 calories over the next 24 hours.

The new review, published in the journal Frontiers in Physiology, looked at all the available evidence on the impact of cold water immersion on brown fat.

The researchers found that, in general, cold water immersion does increase brown fat activity.

But they also found that the evidence is mixed on whether this has any other benefits.

For example, some studies have found that cold water immersion can increase metabolism and help people burn more calories.

But other studies have found no such effects.

The researchers say the effects of cold water immersion on other types of body fat are even less clear.

And the evidence on whether cold water immersion has any meaningful impact on health is also mixed.

So, while cold water immersion may have some benefits for brown fat, it’s not clear if these benefits extend to other types of fat or if they have any real-world impact on health.

According to a new study, taking a dip in icy water may help reduce unhealthy belly fat. The findings, published in the journal Obesity, suggest that cold water immersion may be a simple and easily accessible way to help reduce visceral fat, which is a type of body fat that is stored within the abdominal cavity and is linked to an increased risk of heart disease and type 2 diabetes.

Previous studies have shown that cold water immersion can help boost metabolism and burn calories, but the new study is the first to specifically look at its effects on visceral fat. For the study, researchers recruited 16 healthy men and women who were of normal weight or slightly overweight. The participants were asked to sit in a 60-degree Fahrenheit (15.6-degree Celsius) room for two hours, followed by sitting in a 54-degree Fahrenheit (12.2-degree Celsius) room for another two hours.

After four hours, the participants underwent an MRI scan to measure their visceral fat. The results showed that those who had been in the colder room had a significant reduction in their visceral fat, compared to those who had been in the warmer room.

Although the findings are promising, the authors note that more research is needed to determine the long-term effects of cold water immersion on visceral fat. Additionally, it is not clear whether the reduction in visceral fat would lead to any improvements in health. Nevertheless, the authors say that their findings suggest that cold water immersion may be a simple and safe way to help reduce visceral fat.
