Visual food cues decrease postprandial glucose concentrations in lean and obese men without affecting food intake and related endocrine parameters.

- 01 Oct 2017

- Vol. 117, pp 255-262

TL;DR: Testing the hypothesis that watching high-calorie food cues increases food intake and modifies anticipatory blood parameters in lean and especially in obese men indicates that exposure to food cues does not acutely trigger calorie overconsumption but rather improves the glucoregulatory response to food intake.

1. What are the contributions in this paper?

In this paper, the authors investigated the effect of watching pictures of high-calorie food items versus neutral contents on food intake measured during a standardized test buffet and subsequent snacking.

Figure 2: Parameters of glucose homeostasis. Mean ± SEM plasma or serum concentrations of 315 glucose (A, B), insulin (C, D) and C-peptide (E, F) during baseline and after watching food pictures 316 (black squares) or neutral items (white circles). Baseline concentrations of glucose, insulin and C-317 peptide were comparable between conditions and groups (all p > 0.1). Blood samples were drawn at 318 0950h (-20min), 1010h (0min), 1025h (15min), 1105h (55min), 1130h (80min), 1145 (95min), and 319 1205h (115min). 320

Figure 1: Total calorie intake in the test buffet and snack test. Mean ± SEM total intake of 261 kilocalories in the test buffet (A) and snack test (B) after watching pictures of palatable food (black 262 bars) or neutral items (white bars) in lean and obese men. 263 264 In the additional experiment, where lean men were presented with pictures of 265 high-calorie food items that were offered for consumption later on or with control 266 pictures, we did not find differences in total calorie intake between conditions (1781 ± 267 109 kcal vs. 1711 ± 105 kcal, t(9) = 0.66, p > 0.3). In the subsequent snack test, 268 participants ingested comparable amounts of total calories in both conditions (183 ± 269 40 kcal vs. 191 ± 52 kcal; t(8) = 0.78, p > 0.7). 270

TL;DR: Modulating the release of the endogenous stores of GLP1 and other gut hormones is thought to be a promising strategy to mimic bariatric surgery with its multifaceted beneficial effects on food intake, body weight and blood glucose levels.

TL;DR: Ghrelin appears to modulate the response to food cues via a neural network involved in the regulation of feeding and in the appetitive response toFood cues, and it increases the response of brain areas involved in visual processing, attention, and memory to food pictures.

TL;DR: Röder et al. as discussed by the authors found that the initial cephalic phase of insulin secretion is mediated through the vagus nerve and is not due to glycemic stimulation of pancreatic β cells.

TL;DR: In this paper, the authors summarized the evidence from animal and human research on cephalic responses and found that the majority of studies demonstrated that hormonal levels are changed in response to cues previously associated with food intake, such as feeding time, smell and sight of food.
