Baclofen reduces intake of some foods but stimulates intake or has no effect on others.
We sought to explore whether meal variety stimulates intake by influencing pre-meal planning.
For example, cattle neuropeptide Y (NPY) stimulates food intake, oxytocin stimulates smooth muscle contraction, vasopressin stimulates water re-absorption in the kidney, and ghrelin stimulates appetite and feeding activity through interactions with NPY and other peptides [ 3].
Evidence suggests that fat-free mass plays a major role in appetite regulation, stimulating food intake, and our data contribute to this evidence base [43, 44].
Results suggest that finely ground barley grain is no different than dry-rolled and steam-rolled barley grains in stimulating feed intake and productivity of midlactation cows, when 256 g of dietary DM/kg is barley grain.
We hypothesized that finely ground barley grain is as effective in stimulating feed intake and milk production as are dry- and steam-rolled barley grain, and so the objective was to determine effects of feeding either (1) finely ground, (2) steam-rolled, (3) finely dry-rolled, or (4) coarsely dry-rolled barley grain on rumen fermentation, digestibility and milk yield and composition.
On the other hand, ghrelin is synthesized and secreted both in the stomach and the intestine, stimulating food intake.
It has been shown that endocannabinoids can affect energy metabolism both by stimulating food intake and by affecting energy processing in the adipose tissue, liver, pancreas, and skeletal muscle [ 147, 149, 150].
Meanwhile, as a GH-independent mechanism, ghrelin induces a positive energy balance by decreasing fat utilization [ 11], stimulating food intake and adiposity [ 12], increasing cardiac output in healthy humans [ 13], and inhibiting sympathetic nerve activity [ 13, 14].
Of course, if increased expenditure stimulates food intake then, theoretically, excess intake might stimulate expenditure.
