The researchers also noted an increase in exercise adherence among the rehabilitation group compared to the control group.
The USPSTF has lowered the recommended starting age of screening for type 2 diabetes from 40 to 35. Screening is now recommended for adults with prediabetes or type 2 diabetes, particularly those aged 35-70 who are overweight or obese. This recommendation aims to detect and treat these conditions earlier.
A new study from the University of Georgia found that college students who were physically active before starting university remained so, while those with low motivation to exercise gained significant weight. The researchers recommend teaching children the importance of exercise and healthy eating habits.
Research of over 18,000 mother and child pairs found that maternal obesity was associated with a heightened risk of bowel cancer in adulthood. Conditions in the womb may be key risk factors for the disease, which is expected to increase globally due to rising rates among younger adults.
A new study led by UT Southwestern researchers found that fat cells release extracellular vesicles containing dying mitochondria, which trigger oxidative stress in the heart. However, this stress triggers a strong protective response from antioxidant molecules, reducing cardiac damage.
Researchers uncover a neuro-immune process by which brain signals instruct immune function in visceral fat stores, providing new approaches for fighting obesity and related illness. The study identifies a critical mediator of neuro-immune communication, mesenchymal cells, and reveals the molecular messages exchanged across all steps.
A preclinical study found that high-fructose diets alter villi in the small intestine, leading to increased nutrient absorption and weight gain. Fructose's primary metabolite promotes elongation of villi and supports intestinal tumor growth.
Research suggests that dieting is a consequence of an unhealthy food environment, rather than the cause of weight loss problems. Experts recommend refocusing concerns on changing the food environment to curb dieting and related issues.
The University of Maryland associate professor will use genetics, cell biology, and pharmacology to examine the mechanisms of copper transport and its connection to thermogenesis and fat burning. The research aims to improve human health by understanding how copper relates to hypothermia, obesity, and diabetes.
A high-fat diet causes inflammation and damages intestinal epithelial cells, leading to the growth of harmful microbes and increased production of trimethylamine-N-oxide, a metabolite associated with cardiovascular disease. Researchers found that restoring intestinal function with a drug can blunt this effect.
