Ghrelin News and Research

RSS

Ghrelin is a hormone produced mainly by P/D1 cells lining the fundus of the human stomach and epsilon cells of the pancreas that stimulates appetite. Ghrelin levels increase before meals and decrease after meals. It is considered the counterpart of the hormone leptin, produced by adipose tissue, which induces satiation when present at higher levels. Ghrelin is also produced in the hypothalamic arcuate nucleus where it stimulates the secretion of growth hormone from the anterior pituitary gland.

One-day keto diet boosts energy expenditure, exogenous ketones have little effect

Research aims to compare the effects of a one-day isocaloric ketogenic diet, fasting, and supplementation with ketone salts on energy expenditure and appetite perception. The study found that a 24-hour ketogenic diet may contribute to maintaining a neutral energy balance by increasing energy expenditure.

What is the association between obesity and insulin resistance in youth and its production of colon-derived acetate, gut-derived hormone secretion, and adipose tissue lipolysis?

Researchers assessed whether insulin resistance and adiposity in youth were linked to the fermentation of dietary fibers.

Ingestible capsule uses electricity to boost production of hunger-regulating hormone

Hormones released by the stomach, such as ghrelin, play a key role in stimulating appetite. These hormones are produced by endocrine cells that are part of the enteric nervous system, which controls hunger, nausea, and feelings of fullness.

Obese children who recently lost weight more likely to show hunger-related brain activity after a meal

Children with obesity, who have recently lost weight, are more likely to show hunger-related activity in their brains after a meal, according to research presented today at the 60th Annual European Society for Paediatric Endocrinology Meeting.

Is there a right time for eating?

In a recent study published in the journal Cell Metabolism, researchers assessed how calorie or energy intake (EI) time influences calorie distribution and all energy expenditure (EE) components, which, in turn, impact energy balance and weight loss in healthy obese people.

'Hunger Hormone' may play key role in impulsive choices and behaviors

Higher levels of the stomach-derived hormone ghrelin, which stimulates appetite, predict a greater preference for smaller immediate monetary rewards over larger delayed financial rewards, a new study finds. The study results will be presented at ENDO 2021, the Endocrine Society's annual meeting.

Gut hormone found to be key regulator of new nerve cells in the adult brain

A gut hormone, ghrelin, is a key regulator of new nerve cells in the adult brain, a Swansea-led research team has discovered. It could help pave the way for new drugs to treat dementia in patients with Parkinson's Disease.

Adolescents with “elevated" hunger hormone are more likely to develop post-traumatic stress disorder

Chronic stress increases a blood-based hormone called acyl-ghrelin for years after the initial traumatic stressor exposure in some adolescents, and those with elevated levels of the hormone are more likely to develop post-traumatic stress disorder (PTSD) and to experience more severe cases of the condition, according to a study conducted by researchers at the Icahn School of Medicine at Mount Sinai and published August 20 in JAMA Network Open.
