New study discovers 'fat switch' in body that can turn off weight gain, cholesterol, liver issues
Imagine if your body had a hidden switch that told it when to store fat and what if flipping that switch off could help prevent weight gain, lower cholesterol and protect your liver without drastic dieting? That is exactly what a new cutting-edge study published in Science Signaling on December 23, 2025, reveals and it could completely transform how we think about metabolic health.
This is not about another fad diet or an impossible fitness regime. Scientists have identified a novel enzyme that controls fat synthesis in the body, meaning that our cells literally need this enzyme to make fat. By understanding how it works, researchers are now exploring powerful new ways to curb obesity and improve metabolic health.

The science of fat: A new enzyme takes center stage
The study titled 'The protein denitrosylase SCoR2 regulates lipogenesis and fat storage' identified an enzyme, SCoR2, that plays a critical role in the body’s ability to make and store fat. In simple terms, the enzyme acts like a molecular switch that removes nitric oxide from specific proteins involved in fat and cholesterol synthesis.
When SCoR2 is active, it essentially turns on the body’s fat-building machinery but when researchers blocked this enzyme, even animals on high-fat diets didn’t gain as much weight and their cholesterol levels improved. This is huge because it means fat storage is not just about calories in versus calories out but also about biological signalling pathways deep inside our cells that can potentially be tuned for better health.
Why this is a big deal for your health
The study rethinks the root causes of obesity and weight gain. In today’s world, obesity is a global health crisis, tightly linked with heart disease, diabetes and fatty liver disease. Scientists have long suspected that metabolic enzymes play a role but this study pinpoints a specific control point that could be targeted by future therapies.
Instead of just cutting calories or relying on willpower, regulating key enzymes like SCoR2 might allow the body to better manage fat storage at a cellular level, which can be a potential game-changer in metabolic medicine.
Beyond fat, it promises cholesterol and liver protection too. The same study also found that inhibiting SCoR2 lowered bad cholesterol (LDL) and protected against liver damage in animal models. This suggests that therapies based on this science could help multiple aspects of metabolic health, not just weight loss.
That is exciting because it points toward a multi-targeted strategy of tackling weight, cholesterol and liver health simultaneously. It is a new frontier in metabolic research. This discovery adds to a growing body of science showing that metabolic health is not just about diet and exercise, it is also deeply biological, involving complex signalling systems inside our cells.
By understanding how enzymes like SCoR2 work, scientists are laying the foundation for smarter, more effective interventions for metabolic diseases. However, the science is still early and human clinical trials are needed before new drugs hit the market.
Bottom line
Scientists have identified a fat-regulating enzyme (SCoR2) that could become a target for future therapies against obesity, high cholesterol and liver disease. This is a breakthrough insight published in Science Signaling.
This discovery does not replace healthy eating or exercise but it reframes how we understand metabolic health, from willpower to biology. As researchers continue to explore how fat storage is controlled at the molecular level, we may be on the brink of smarter, more precise ways to stay healthy in the years ahead.
