Researchers at Washington University School of Medicine have found that protein CD36 facilitates the uptake of fatty acids and cholesterol in the proximal part of the intestine. The team believes that targeting this process may provide a useful tool for obesity treatment, as animals without CD36 absorb fat less efficiently and eat less.

The research used data from the Newton Girls Study and found that overweight girls mature earlier, but this does not predispose them to be overweight as adults.
A study of mice found increased body fat despite reduced calorie intake from solid food, suggesting fructose affects metabolic rate and favors fat storage. The research suggests that high-fructose corn syrup in soft drinks may contribute to obesity, with further human studies needed to confirm the findings.

Research suggests that excessive visceral and muscle adipose tissue accumulation is associated with a higher prevalence of metabolic syndrome in older adults, regardless of their body weight. Visceral fat was linked to an increased risk, while subcutaneous thigh fat showed an inverse association in obese individuals.
Researchers have discovered that a compound called HPMC, commonly used as an additive in foods and drugs, may help prevent diabetes in people who frequently consume high-fat fast foods. The compound works by regulating metabolic genes and slowing down the absorption of fats, potentially reducing the risk of developing insulin resistance.
A gene that causes severe fat deficiency is also found to promote obesity in mice, according to new research. The protein affects body weight by altering fat storage and metabolism, with excess levels leading to increased body weight and changes in energy expenditure.

The study also showed that weight loss and regain resulted in changes to the concentration of toxins in adipose tissue and liver.
Research suggests that abdominal fat is more closely associated with disability than overall body fat, even among normal-weight individuals. The study, which followed over 16,000 participants for nine years, found that high levels of abdominal fat increased the risk of difficulty performing daily tasks.
A new study published in the American Journal of Epidemiology found that intra-abdominal fat is a significant predictor of heart attack risk. Researchers discovered that as people age, fat tends to accumulate in the abdomen more than other areas, increasing the risk of heart attacks.
Facial aging is attributed to the loss of facial fat and skin changes, rather than gravitational forces. Plastic surgeons must balance tightening tissue with replacing lost facial fat using wrinkle fillers.
