A recent study conducted by researchers from Southern Danish University in Denmark suggests that activating healthy ‘brown fat’ in the body may help protect against obesity. With more than 1 billion people globally suffering from obesity and the number projected to hit 4 billion by 2050, finding ways to combat the condition is crucial for overall health and disease prevention. The study, published in the journal Nature Metabolism, focused on a protein called AC3-AT, which is responsible for “switching off” brown fat activation. Removing AC3-AT from the genome of mice led to protection against obesity, as their bodies were better at burning calories and their metabolism sped up due to increased brown fat activation.
Humans and other mammals have two main types of fat in the body – white fat and brown fat. While white fat stores calories from foods and expands in obesity, causing medical problems, brown fat converts calories into heat, which can help in weight management and metabolic health. Despite having the most brown fat as babies to help stay warm, the amount decreases as we age, with adults having small amounts mainly in the shoulders, neck, spinal cord, kidneys, and heart. Studies have shown that activating brown fat can improve metabolism, providing potential targets for obesity and diabetes treatments.
Researchers are exploring various ways to increase brown fat levels in adults, such as through exercise or the use of certain drugs. However, as brown fat is primarily developed during fetal stages and doesn’t increase with age, the focus is on stimulating existing brown fat cells to grow and work more efficiently. While it may be challenging to grow more brown fat, stimulating the brown fat cells through methods like ice application or cold water baths can be beneficial.
Studies are ongoing to find safe ways to bring back brown fat activity in adults, particularly in obesity and older age. Pharmacological and environmental approaches, including cold exposure and specific drugs, are being explored to delay the decline in brown fat amount and activity. While research is promising, bariatric surgeon Dr. Mir Ali emphasizes the importance of making healthy food choices in weight management, as stimulating brown fat alone may not be sufficient without proper diet and lifestyle changes.
In conclusion, the activation of brown fat may play a significant role in protecting against obesity and improving metabolic health. While more research is needed to explore ways to increase brown fat levels in adults, current findings suggest that targeting brown fat activation through various methods could have beneficial effects on weight management and overall well-being. Incorporating healthy lifestyle choices, including exercise and proper nutrition, remains essential in effectively managing obesity and reducing the risk of associated diseases.
