A New Approach to Weight Loss: Emphasizing Fat Loss Over Total Weight

Not all fats are created equal. While many individuals concentrate on weight loss as a means to achieve better health, research indicates that the location and proportion of fat storage in the body significantly influence overall well-being. It appears that merely losing weight is not the sole concern; comprehending the distribution of fat within the body is equally crucial.

A study published in BMC Medicine by researchers from Ben-Gurion University of the Negev, in collaboration with international partners, has unveiled intriguing findings regarding visceral fat, which is the fat that encases internal organs. The research demonstrated that the health implications of visceral fat differ based on whether it is assessed by its absolute area or in relation to other fat deposits.

Why fat distribution matters more than just BMI

For many years, the medical community has recognized that visceral fat poses greater health risks than subcutaneous fat. This recent study offers fresh perspectives on the dangers associated with obesity, highlighting the significance of fat distribution rather than merely the overall reduction of fat. According to Iris Shai, the author of the study, "These findings present a novel approach to assessing weight loss, concentrating on the type of fat that is lost and its effects on metabolic health."

Research on 572 participants reveals visceral fat area impacts inflammation and insulin resistance.

Analyzing 572 participants over 18 months, researchers found that while the visceral fat area was linked to inflammation and insulin resistance, its proportion was associated with high triglycerides. Notably, participants lost 22.5% of their visceral fat area but only saw a slight 1.3 percentage point drop in its proportion. While reducing visceral fat area improved insulin resistance and inflammation, lowering its proportion benefited liver function and blood fat levels.

“Two people with the same BMI can have different metabolic risks based on visceral fat distribution,” says co-lead author Hadar Klein. Co-lead author Hila Zelicha adds, “Understanding visceral fat dynamics can help tailor diet and exercise plans for better health outcomes.”

Rethinking weight loss and health strategies

Many evaluations of obesity primarily depend on Body Mass Index (BMI) or waist circumference measurements, which fail to consider the distribution of body fat. This oversight may neglect individuals who possess a "normal" BMI yet have unhealthy levels of body fat, a condition referred to as normal weight obesity.

A study highlights that fat distribution, particularly visceral fat, plays a crucial role in health.

Enhanced analysis of fat distribution could significantly refine health risk evaluations and tailor treatments to individual needs. For instance, individuals exhibiting insulin resistance may find it beneficial to decrease their visceral fat area, whereas those facing cholesterol-related concerns might prioritize reducing their visceral fat proportion.

The research established models utilizing standard clinical indicators such as waist circumference, age, and blood tests to estimate both visceral fat area and proportion, thereby facilitating assessments without the need for expensive MRI scans. Furthermore, the findings indicated that not all types of fat exhibit the same characteristics; superficial subcutaneous fat is associated with improved cholesterol levels, while deep subcutaneous fat correlates with increased insulin resistance and heightened diabetes risk. Historically, BMI and weight loss have served as the main health indicators, but this study highlights the critical role of fat distribution in the prevention of diabetes, cardiovascular diseases, and metabolic disorders.
