Definition: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: Increased consumption of a high-fat (HF) diet is a salient contributor to obesity; however, how diminished satiation signaling contributes to overconsumption and obesity development remains poorly understood.', 'Using obese-prone (OP) and obese-resistant (OR) rats, we tested feeding responses to intragastric liquid meal replacement, prior and after HF feeding. Next, chow- and HF-fed OP and OR rats were tested for sensitivity to intraduodenal glucose, intralipid, and meal replacement loads. To examine the role of glucagon-like peptide-1 (GLP-1) and vagal signaling, animals were treated with exendin-9, GLP-1 receptor antagonist, prior to meal replacement infusion, and Fos-like immunoreactivity (Fos-Li) in the dorsal hindbrain was examined after infusion.', 'OP and OR rats reduced chow intake equally following gastric liquid meal; however, after 2 weeks of HF feeding, intragastric meal replacement reduced food intake less in OP than OR. Similarly, HF feeding, but not chow, diminished the suppressive effects of intraduodenal meal replacement, glucose, and intralipid in OP compared to OR. This effect was associated with lower Fos-Li expression in the dorsal hindbrain of OP rats. Finally, exendin-9 failed to attenuate reduction of food intake by meal replacement in OP rats during HF feeding.
Output:
Does impaired GLP-1 signaling contribute to reduced sensitivity to duodenal nutrients in obesity-prone rats during high-fat feeding?
