From an abundance of weight loss supplements and ancient fat-burning herbs to fad diets and celebrity-approved exercise classes, it’s no secret that the world is very interested in losing weight—and keeping it off. While there is no replacement for good ol’ fashioned exercise and a healthy, balanced diet, scientists may have found a way to facilitate shedding those few extra pounds.
Chubby mice slim down with a little help from a skin patch
Researchers recently developed a small patch to test whether a special “browning agent” could convert white fat into brown fat and speed fat loss in mice. The patch, composed of numerous microneedles that allowed them to deliver small particles of browning agent under the skin, was applied to just one side of the bodies of obese test mice.
Over time, mice who wore the patch with the browning agent had 20% less fat on that side of their bodies. They also had lower blood sugar levels compared to control mice who did not wear the skin patch.
What is the difference between brown and white fat?
If you found yourself scratching your head in confusion reading the above, you’re not alone—most people have no idea that there are different types of stored body fat. Let’s break it down.
Along with carbohydrates and protein, fat is one of the three main macronutrients and a necessary component in a healthy diet. Despite negative connotations around the word fat, the human body requires a certain amount of it to properly function. It provides energy, helps you absorb fat-soluble vitamins, protects your organs, and insulates the body. Dietary fat comes in many varieties, such as saturated or trans fat.
The fat that is stored in your body comes in just two types: brown fat and white fat—and like cholesterol, there’s a clear “good” and “bad” variety.
- Brown fat, the good fat, is made up of several small, oily fat droplets plus iron-containing mitochondria and has a brownish appearance. It is most often found in the upper back and surrounding the neck. This fat has an important role: it helps to burn calories and generate heat. Brown fat is largely found in younger children and infants—it is most often what people are referring to when they say “baby fat.” As you age, your natural levels of brown fat decrease, making it easier to put on and retain excess weight. Brown fat levels can be increased by exercise, a great sleep routine, and exposing yourself to chillier temperatures.
- White fat, on the other hand, is the most predominant in adult bodies. It is made up of just one fat droplet and far fewer blood vessels and mitochondria than its brown counterpart. Just because this fat doesn’t fall into the “good” category doesn’t mean it does not have its uses—white fat is what insulates and cushions your organs and produces hormones that regulate hunger. Problems occur when too much white fat exists, which happens when more calories are consumed than burned.
In sum, brown fat, which burns calories, can help regulate the abundance of white fat in the body—which is what the study accomplished in test mice.

We’re not quite there yet, but there are tried & true ways to reduce unwanted fat
Shedding excess pounds by simply wearing a special patch sounds incredible, but don’t rejoice just yet—this study is in its beginning stages, and there’s no guarantee that human beings would experience the same promising results as mice.
