Studies suggest that women who have undergone weight loss surgery need to eat less fat after surgery in order to fully enjoy the benefits of surgery and protect liver function.The study is published before printing American Journal of Physiology-Endocrinology and Metabolism..

Over 42% of adults living in the United States are considered obese and are at increased risk of developing chronic health conditions such as type 2 diabetes. Heart disease Or cancer. According to the American Society for Metabolic and Bariatric Surgery, an estimated 256,000 people in the United States Weight loss 2019 (weight loss) surgery.

However, studies have shown that men and women do not respond equally to weight loss interventions. “There are signs of that [biological] Gender affects the degree of weight loss and improvement of comorbidities, “writes a new mouse study researcher.

The researchers studied a mouse model of vertical sleeve gastrectomy. Weight loss surgery The stomach has been reduced to about 15% of its original size. After treatment, some mice maintained a high-fat diet given prior to surgery, and others were fed a low-calorie diet. The researchers found that both male and female mice had better glucose tolerance and lost weight and body fat after surgery, even if they continued on a high-fat diet. However, men had a greater reduction in liver fat storage (liver triglycerides) than women. Male mice showed improvement in hepatic triglycerides regardless of diet, but only females on a low-calorie diet showed a significant improvement. According to the Fatty Liver Foundation, high levels of liver triglycerides are markers of fatty liver disease, affecting up to 100 million people in the United States. Fatty liver disease can cause liver cancer and liver failure in some cases.
