Leptin Sensitivity

In rats selectively bred to develop diet-induced obesity (DIO) 3 wk of postweaning exercise reduces weight and adipose regain for 10 wk after exercise cessation, despite intake of 31% fat high-energy (HE) diet. To test the hypothesis that this effect is due to increased central leptin sensitivity, 4-wk-old DIO rats were fed the HE diet and left sedentary (Sed), exercised for 3 wk, and then remained sedentary for 10 additional weeks (Ex/Sed) or continued exercise for a full 13 wk (Ex). After 3 wk, leptin (5 mg/kg ip) induced a 36% decrease in 24-h food intake in Ex rats, while Sed rats had no change in 24-h intake. Ex rats also had 23% more leptin-induced phospho-STAT3 (pSTAT3)-expressing neurons in the arcuate nucleus (ARC) and 95% and 68% higher 125I-labeled leptin receptor binding in the ventromedial and dorsomedial nuclei than did Sed rats, respectively. At 7 wk after onset, leptin decreased 24-h intake by 20% in Ex and 24% in Ex/Sed rats without altering Sed intake. After a total of 13 wk, compared with Sed rats, Ex and Ex/Sed rats had 58% and 38% less fat, respectively, but leptin failed to decrease food intake in any group. Nevertheless, Ex, but not Ex/Sed rats, still had 32% more ARC leptin-induced pSTAT3-expressing neurons than Sed rats. These data suggest that brief postweaning exercise in DIO rats that are inherently leptin resistant causes a sustained resistance to obesity on HE diet, which is, in part, due to increased central leptin sensitivity.

Friedman. “Hepatic portal glucose infusions decrease food intake and increase food preference.” Page R195: first paragraph, the first four sentences should read In addition to the theoretical implications of these results, several practical implications are apparent. The data suggest that repeated tests of the same subject must be interpreted with caution, because the response during later tests may well be determined by previous infusions. It is interesting to note in this regard that several previous studies finding no change in feeding after hepatic portal glucose infusion have used daily tests according to counterbalanced designs (Refs. 2, 13, and 17–20 and perhaps Refs. 26, 27, and 29).

Abstract Objectives The objective of this study was to a) determine the feasibility of eating in virtual reality (VR) environment while wearing a head mounted display (HMD) and b) determine the effect of eating in a virtual restaurant on food intake, sensory evaluation of the test food and masticatory parameters. Methods Fifteen adults were asked to report to the laboratory on two occasions, separated by at least one week, at their usual lunchtime. On reporting to the laboratory, surface electrodes were attached to the left and right masseter muscles to measure masticatory activity and a wristband placed on the non-dominant wrist to collect physiological data. The participant sat quietly for 5 minutes before a VR (HMD) was placed on their head. The HMD displayed either a virtual restaurant (pizzeria) or a blank scene (consisting of a white background and a table). The participant's hand movements were captured using an infrared camera mounted on the HMD so when the participant moved their hands this was represented by computer generated model hands in the VR scene. The test foods (pizza bites) were represented in VR using a 3D model of pizza bites. The test foods were arranged so that when the participant touched the test food model in the VR scene they touched the test food in real life allowing them to locate and pick up the test food. The participant was instructed to eat the test food until they felt comfortably full.  When the participant finished eating the equipment was removed and they completed questionnaires regarding their feelings of presence and experiences in the VR environment and their ratings of the test food attributes. Results Participants were able to successfully locate and eat the pizza rolls while in the VR environment. The participants feeling of presence was higher in the restaurant scene compared to the blank scene (P < 0.05). Heart rate and skin temperature were higher in the restaurant scene (P < 0.05). Differences in masticatory parameters were found with participants using fewer masticatory cycles before swallowing in the restaurant scene (P < 0.05). There were no differences between scenes regarding the sensory evaluation of the test foods. There was no difference in food intake between the treatments. Conclusions Eating in VR is feasible and may provide a new method to understand eating behavior in different contexts. Funding Sources None.
