A recent animal study found that trans fat consumption can lead to weight gain despite controlled calorie intake. The study, led by Kylie Kavanagh and Lawrence L. Rudel, discovered that male monkeys fed a western-style diet rich in trans fat gained 7.2% more body weight compared to those on a monounsaturated fat diet.
Obesity disrupts hormone signaling pathways and leads to metabolic changes that worsen liver disease. Researchers recommend weight loss, insulin-sensitizing drugs, or increased dosages of combination therapy to improve treatment outcomes for hepatitis C patients.

Fat cells surrounding coronary arteries release pro-inflammatory proteins and hormones that regulate inflammation, blood pressure, and insulin activity. These epicardial adipocytes also induce angiogenesis, a process that contributes to the development of atherosclerosis.
A study found that vitamin C depletion is associated with lower body fat, but not with weight loss in a short-term low-fat diet. Participants who took a vitamin C supplement had increased blood levels of vitamin C and improved ability to oxidize fat.
Research found a significant association between high leptin levels and asthma risk in women, but not men. The study suggests leptin may play an independent role in increasing asthma risk, rather than being linked to obesity.
A midriff bulge roughly doubles a woman's chances of needing gallstone surgery, according to a comprehensive study. The study, which monitored over 42,000 women for two years, found that women with larger waist sizes were more likely to develop gallstones.

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.
