Researchers linked dietary cholesterol to exacerbation of viral infections in mice, showing that high levels of cholesterol made mice sicker when infected with influenza. The study found that dietary cholesterol increased the number of cytokine-producing immune cells in the lungs, contributing to excessive inflammation.
A new weight-loss intervention has been developed to target the instinctive desire to eat, particularly in individuals who struggle with resisting food cues. The Regulation of Cues program trains individuals to use natural hunger cues, reinforces tolerance of cravings, and inhibits urges to eat palatable foods when not physically hungry.
A recent study published in Obesity Reviews found that resistance training, in conjunction with a reduced calorie diet, can lead to significant fat mass and muscle loss. This breakthrough highlights the importance of considering non-aerobic exercise options for individuals struggling with obesity.
