 Exeter, United Kingdom. A fifteen minute walk can cut snacking on chocolate at work by half, according to research; even in stressful situations, workers eat only half as much chocolate as they normally would after this short burst of physical activity.The findings suggest that employees may find that short breaks away from their desks can help keen their minds off snacking.  Chocolate consumption can be cut in half after a 30-minute brisk walk, according to research by the University of Exeter. The study showed that, even in stressful situations, workers eat only half as much chocolate as they normally would after this short burst of physical activity.In the study, published in the journal Appetite, 78 regular chocolate-eaters were invited to enter a simulated work environment, after two days abstinence from chocolate snacking. Two groups were asked to take a brisk 15-minute walk on a treadmill and were then given work to complete at a desk.
Chocolate was available in a bowl on the desk for all participants as they carried out their work.
Lead researcher Professor Adrian Taylor of the University of Exeter said: "We know that snacking on high calorie foods, like chocolate, at work can become a mindless habit and can lead to weight gain over time". "We often feel that these snacks give us an energy boost, or help us deal with the stress of our jobs, including boredom," Taylor says. As a result, people often find it difficult to cut down on their daily treats but this study shows that by taking a short walk, they are able to regulate their intake by half." Exercise is known to have significant benefits for mood and energy levels and has potential for managing addictions. Professor Taylor and his colleagues at the University of Exeter have previously shown that exercise can curb cravings for chocolate but this is the first study to show a reduction in consumption.

Highlights ● Exercise almost halved ad libitum chocolate consumption among regular chocolate eaters, while performing a computerised task. ● The level of task demand had little influence on the results. ● Exercise also increased level of affective activation. ● Changes in affective activation did not mediate the effects of exercise on chocolate consumption. Abstract Workplace snacking can contribute to obesity. Exercise reduces chocolate cravings but effects on chocolate consumption are unknown. This study investigated the effect of brief exercise on ad libitum consumption during breaks in a computerised task. Seventy-eight regular chocolate eaters, age: 24.90 ± 8.15 years, BMI: 23.56 ± 3.78 kg/m2 abstained for 2 days. They were randomly assigned to one of four conditions, in a 2 × 2 factorial design, involving either a 15 min brisk walk or quiet rest, and then computerised Stroop tasks with low or high demanding conditions, in three 180 s blocks with a 90 s interval. Throughout, a pre-weighed bowl of chocolates was available for ad libitum eating. A two-way ANOVA revealed no interaction effect of exercise and stress on total chocolate consumption, or main effect of stress, but a main effect of exercise [F(1, 74) = 7.12, p < .01]. Mean (SD) chocolate consumption was less (t(73.5) = 2.69, 95% CI for difference 3.4–22.9, ES = 0.61) for the exercise (15.6 g) than control (28.8 g) group. Exercise also increased affective activation, but there was no mediating effect of change in affect on chocolate consumption. A brief walk may help to reduce ad libitum snacking in regular chocolate eaters. Keywords: stress, exercise, physical activity, snacking, food craving, self-regulation.
