A specific gene called protein kinase C beta (PKC beta) plays a crucial role in the weight-gain response to a high-fat diet. Mice genetically engineered to lack PKC beta showed minimal health effects and resisted fat-induced obesity, insulin resistance, and liver damage. The study suggests that blocking this gene could be a therapeutic...
A study by University of Cincinnati researchers found that high-fat diets can cause inflammation in fat tissue surrounding blood vessels, potentially leading to cardiovascular disease. The study suggests a direct link between poor dietary habits and inflammation of blood vessels, independent of weight gain or cholesterol levels.
A gene variant that protects against weight gain and insulin resistance becomes a bad actor on high-fat diets, new research suggests. Mice with the Ala12 variant show improved insulin sensitivity and better plasma lipid profiles on balanced diets but worsen these outcomes when fed a diet high in fat.
A high-fat diet can affect circadian rhythms, leading to hormone imbalance, obesity, psychological disorders, and cancer. Fasting and a low-fat diet regulate adiponectin signaling pathways, while a high-fat diet disrupts these pathways, contributing to metabolic disorders.
Research published in The FASEB Journal found that a mother's high-fat diet during pregnancy can lead to oversized offspring and an increased risk of obesity in children. This is because fat causes the placenta to produce excessive nutrients for the fetus.
A new study found that exposing fetal mice to high saturated fats can cause them and their offspring to develop type 2 diabetes. This unusual form of inheritance, known as metabolic programming, has implications for human health, particularly for children born to malnourished mothers.
