Cck Release

Both load and duration of small intestinal lipid infusion affect antropyloroduodenal motility and CCK and peptide YY (PYY) release at loads comparable to and higher than the normal gastric emptying rate. We determined 1) the effects of intraduodenal lipid loads well below the mean rate of gastric emptying on, and 2) the relationships between antropyloroduodenal motility, CCK, PYY, appetite, and energy intake. Sixteen healthy males were studied on four occasions in double-blind, randomized fashion. Antropyloroduodenal motility, plasma CCK and PYY, and appetite perceptions were measured during 50-min IL (Intralipid) infusions at: 0.25 (IL0.25), 1.5 (IL1.5), and 4 (IL4) kcal/min or saline (control), after which energy intake at a buffet meal was quantified. IL0.25 stimulated isolated pyloric pressure waves (PWs) and CCK release, albeit transiently, and suppressed antral PWs, PW sequences, and hunger ( P < 0.05) but had no effect on basal pyloric pressure or PYY when compared with control. Loads ≥ 1.5 kcal/min were required for the stimulation of basal pyloric pressures and PYY and suppression of duodenal PWs ( P < 0.05). All of these effects were related to the lipid load ( R > 0.5 or < −0.5, P < 0.05). Only IL4 reduced energy intake (in kcal: control, 1,289 ± 62; IL0.25, 1,282 ± 44; IL1.5, 1,235 ± 71; and IL4, 1,139 ± 65 compared with control and IL0.25, P < 0.05). In conclusion, in healthy males the effects of intraduodenal lipid on antropyloroduodenal motility, plasma CCK and PYY, appetite, and energy intake are load dependent, and the threshold loads required to elicit responses vary for these parameters.

Experimental Trials

Previous investigations have suggested that exercise at intensities greater than 70% maximal oxygen uptake (VO2max) reduces gastric emptying rate during exercise, but little is known about the effect of exercise intensity on gastric emptying in the postexercise period. To examine this, 8 healthy participants completed 3 experimental trials that included 30 min of rest (R), low-intensity (L; 33% of peak power output) exercise, or high-intensity (H; 10 × 1 min at peak power output followed by 2 min rest) exercise. Thirty minutes after completion of exercise, participants ingested 595 ml of a 5% glucose solution, and gastric emptying rate was assessed via the double-sampling gastric aspiration method for 60 min. No differences (p > .05) were observed in emptying characteristics for total stomach volume or test meal volume between the trials, and the quantity of glucose delivered to the intestine did not differ between trials (p > .05). Half-emptying times did not differ (p = .902) between trials and amounted to 22 ± 9, 22 ± 9, and 22 ± 7 min (M ± SD) during the R, L, and H trials, respectively. These results suggest that exercise has little effect on postexercise gastric emptying rate of a glucose solution.

Scintigraphic Gastric Emptying

In order to establish the efficacy of labelling a solid meal and a semi-solid meal with either 111ln-labelled polymer beads or 99mTc-tin colloid beagle dogs were fed variously labelled meals of different consistencies and then monitored by scintigraphy for gastric motility patterns. The labelling with each tracer was either performed by thoroughly mixing it into the food before cooking, or alternatively by surface labelling after the food had been cooked. For the 99mTc-Sn- colloid tracer no difference was found in the measured gastric emptying times resulting from either pre-cooking labelling or surface labelling of the meals. Cooking the tracer together with the ingredients does however seem to promote a firm entrapment of the 111ln-polymer beads into a solid protein, and in this manner the111In-labelled resin appears to be a reliable solid food tracer. Surface labelling with 111ln-polymer beads of a solid meal with a smooth texture fails totally and the tracer empties with the liquid phase.

Specific Food

The aim of this study was to determine the extent to which gastric layering and retention of a meal could be used to reduce appetite using the same caloric load. Liquid (control) and semi-solid (active) meals were produced with the same protein, fat, carbohydrate, and mass. These were fed to 10 volunteers on separate days in a crossover study, and subjective appetite ratings, gastric contents, and plasma cholecystokinin (CCK) were assessed over a period of 3 h. The active meal showed food boluses in the stomach persisting for ∼45 min, slower emptying rates, and lower plasma CCK levels over the first hour. After the first hour, both gastric emptying rates and plasma CCK levels were similar for both systems and slightly increased compared with the unfed situation. Despite the lower plasma CCK levels for the active meal over the first hour, this meal reduced appetite more than the control meal over the 3 h of the study. For a moderately increased plasma CCK level in the fed state, appetite was correlated with the volume of gastric contents rather than gastric emptying rates or plasma CCK. This suggests that enhanced gastric retention was the key factor in decreasing appetite and was probably mediated by a combination of intestinal nutrient sensing and increased viscosity in the stomach.
