A study published in Pediatrics found that children who underwent surgery for obstructive sleep-disordered breathing (OSDB) due to enlarged adenoids experienced a significant increase in excess weight, averaging 13% over 12.6 months. This weight gain may be linked to reduced motor activity and poor sleep quality after the surgery.
A Rutgers University study found that college students experience average weight gain of seven pounds during their first year, primarily resulting from consuming excess calories. The researchers recommend adopting a balanced diet and increasing exercise to prevent weight gain and associated health risks.
Scientists studied mice lacking POMC gene to understand obesity and fat distribution. The research shows that cortisol levels are not the sole factor, but rather part of a chain of hormonal signals associated with obesity. Glucocorticoids were found to accelerate weight gain and diabetes in treated mice.
Researchers dispelled the myth that eating late at night causes weight gain. Female rhesus monkeys on a high-fat diet gained 5% more weight after having their ovaries removed, showing ovarian hormones play a role in weight balance. The study found no correlation between late-night eating and weight gain.
In a study published in Biology Letters, researchers found that male monkeys of two species experience a 10% weight gain when their mates are pregnant. This gain is likely due to hormonal changes, including increased prolactin and estrogen levels. The study's findings could provide insights into human fathering behavior and motivate me...
Researchers have discovered a new key area in the brain that responds to the fat hormone leptin, which plays a crucial role in resisting high-fat-diet-induced obesity. The ventromedial hypothalamus (VMH) region, previously thought to only be involved in appetite regulation, was found to also respond to leptin and is essential for maint...
