Message: <blockquote data-quote="Oldvatr" data-source="post: 2508148" data-attributes="member: 196898">I think you will find it has the opposite effect.  The hunger hormone is Grehlin, which is produced mainly in the stomach but also small amounts from the small intestine and pancreas (but by somatostatin, not by insulin).  It is triggered when the stomach is empty or sugar levels are low, and reduces shortly after eating a meal.  It is the insulin release due to the meal that lowers grehlin.Patients who have had gastric bypass do not have the pre meal hunger pangs which aids the weight loss associated with that intervention and this is due to the loss of grehlin release.There are studies that show that aerobic exercise and HIIT can lead to hunger pangs, but circuit training and gentle exercises do not.  This seems to be correlated with the reports on this site that intense exercise seems to increase blood sugar levels, and I postulate that the culprit is adrenaline  (epinephrine) which supresses glucose and lipid storage so the sugar remains in the blood unless burnt off by the exercise.One interesting 'fact' I encountered in my research is that grehlin is increased by cannabis, but only when taken orally but not when smoked.  Pity that Hash Brownies are not LCHF.</blockquote>
