“…*Significant difference (P , 0?01) between conditions consumed and not consumed. Although the mean heart rate in the morning was significantly higher in participants on days when they had consumed breakfast, the average increase was only 5 bpm, which can be accounted for by the thermic effect of food (34) . Studies comparing the daily energy intakes of breakfast eaters and non-breakfast eaters have revealed conflicting results.…”

Objective: To experimentally compare the effects of eating or skipping breakfast on energy expenditure, activity levels and dietary habits. Design: A randomised cross-over trial, lasting 2 weeks. Participants were provided breakfast during one week and were required to fast until mid-day during the other week. Setting: University campus. Subjects: Forty-nine participants (twenty-six female and twenty-three male participants) were recruited. Food intake was monitored using food diaries, and energy expenditure was assessed using pedometers and heart rate monitors. Morningness-eveningness, physical activity and health were assessed using validated questionnaires. Results: Across all participants, daily energy expenditure did not differ between the two experimental conditions. Total energy intake over 24 h did not vary with condition (male participants: 8134 (SD 447) kJ/d and 7514 (SD 368) kJ/d; female participants: 7778 (SD 410) kJ/d and 7531 (SD 535) kJ/d, for the breakfast and no-breakfast conditions, respectively). However, when comparing habitual breakfast eaters with those with irregular or breakfast-skipping habits, it was found that male non-habitual breakfast eaters consumed significantly (P 5 0?029) more energy during the breakfast condition. Furthermore, female participants who were habitual breakfast eaters were found to eat significantly (P 5 0?005) more and later in the day under the no-breakfast condition. Conclusions: Although the suggestion that breakfast is a behavioural marker for appropriate dietary and physical activity patterns is not refuted by the present findings, our data suggest that the effect of breakfast may vary as a function of gender and morning eating habits, and thus there may be other mechanisms that link BMI and breakfast consumption behaviour.

“…This suggests that subjects were more 295 physiologically challenged during exercise on BO, although this was not reflected in RPE, 296 VO 2 or energy expenditure. Digestion and absorption of nutrients from the gut is a process 297 that requires oxygen to be delivered to the splanchnic tissue, typically achieved via a 298 redistribution of blood away from the skeletal muscle or an increase in cardiac output [28]. 299…”

Breakfast omission induces compensatory eating behaviour at lunch, but often reduces daily 21 energy intake. This study investigated the effect of breakfast omission on within-day 22 subjective appetite, energy expenditure, substrate utilisation and appetite hormone profiles, in 23 response to standardised feeding and exercise. Eight male, habitual breakfast eaters 24 completed two randomised trials. Subjects arrived overnight fasted (0 h), and either 25 consumed (BC) or omitted (BO) a standardised breakfast (Mean (SD) (3085 (217) kJ). Lunch 26(4162 (510) kJ) and dinner (4914 (345) kJ) were provided at 4.5 and 10 h, respectively and 27 subjects performed 60 min fixed-intensity cycling (50% VO 2 peak) at 8 h. Blood samples 28 were collected at 0, 4.5, 6 and 8 h, with expired air and subjective appetite sensations 29 (hunger, fullness, desire to eat (DTE) and prospective food consumption (PFC)) collected 30 throughout. Heart rate and perceived exertion were measured during exercise. Hunger, DTE 31 and PFC were greater and fullness lower during BO (P<0.05) between breakfast and lunch, 32 with no differences after lunch (P>0.193). Resting energy expenditure was greater at 2.5 h 33 during BC (P<0.05) with no other differences between trials (P>0.156). GLP-1 7-36 was 34 greater (P<0.05) and acylated ghrelin tended to be greater (P=0.078) at 4.5 h during BC. 35Heart rate was greater on BO (P<0.05) during exercise. The results of this laboratory-36 controlled study suggest that the effects of breakfast omission are transient and do not extend 37 beyond lunch, even when the negative energy balance created by breakfast omission is 38 sustained via standardised feeding and exercise.

Postprandial silent ischaemia following a fatty meal in patients with recently diagnosed coronary artery disease

Silent myocardial ischaemia (SI) is recognised as an important prognostic factor in patients with coronary artery disease (CAD). Postprandial angina is related to severity of CAD. The effect of postprandial metabolic changes in the pathogenesis of SI is unclear. We studied the postprandial changes in glucose, insulin and triglyceride, and non-esterified fatty acids (NEFA) in relation to postprandial SI and exercise capacity, in patients with CAD. Forty elderly volunteers (63 ؎ 1 years) mean age ؎ s.e.m., with a history of angina were selected on the basis of a Rose questionnaire and a positive exercise stress test (modified Bruce protocol). The test meal contained 45% fat. The meal was consumed at 9.00 am and hourly blood samples were taken for glucose, insulin, triglyceride and NEFA. Continuous Holter monitoring for SI was conducted using a Space-
