“…It has been suggested that 24-h diaries and recalls are a sensitive dietary assessment tool at the group level but not at the individual level, unless multiple recalls are used ( Ma et al., 2009 ). As this was a preliminary study and we wanted to avoid excess burden on participants, we only used two diaries in our pre- and post-intervention week, which may not have provided sufficient sensitivity to detect individual changes that were correlated with weight loss ( Pears et al., 2012; Ma et al., 2009 ). It is also possible that other mechanisms that were not measured, such as changes in exercise, contributed to weight loss.…”

Training response inhibition to food is associated with weight loss and reduced energy intake

The majority of adults in the UK and US are overweight or obese due to multiple factors including excess energy intake. Training people to inhibit simple motor responses (key presses) to high-energy density food pictures reduces intake in laboratory studies. We examined whether online response inhibition training reduced real-world food consumption and weight in a community sample of adults who were predominantly overweight or obese (N = 83). Participants were allocated in a randomised, double-blind design to receive four 10-min sessions of either active or control go/no-go training in which either high-energy density snack foods (active) or non-food stimuli (control) were associated with no-go signals. Participants' weight, energy intake (calculated from 24-h food diaries), daily snacking frequency and subjective food evaluations were measured for one week pre- and post-intervention. Participants also provided self-reported weight and monthly snacking frequency at pre-intervention screening, and one month and six months after completing the study. Participants in the active relative to control condition showed significant weight loss, reductions in daily energy intake and a reduction in rated liking of high-energy density (no-go) foods from the pre-to post-intervention week. There were no changes in self-reported daily snacking frequency. At longer-term follow-up, the active group showed significant reductions in self-reported weight at six months, whilst both groups reported significantly less snacking at one- and six-months. Excellent rates of adherence (97%) and positive feedback about the training suggest that this intervention is acceptable and has the potential to improve public health by reducing energy intake and overweight.

“…In addition, reporting of dietary intake is often problematic [39], and the single-item self-reported measure of snacking may have been unreliable. Additional measures such as a 24 hour food recall diary could have provided a more accurate account of participant’s snack intake [40]. The measure used in both Study 1 and Study 2 also focused on the number of high-calorie snacks consumed, and did not account for the nutritional value or portion size of each snack.…”

Promoting the Avoidance of High-Calorie Snacks: Priming Autonomy Moderates Message Framing Effects

The beneficial effects of gain-framed vs. loss-framed messages promoting health protective behaviors have been found to be inconsistent, and consideration of potential moderating variables is essential if framed health promotion messages are to be effective. This research aimed to determine the influence of highlighting autonomy (choice and freedom) and heteronomy (coercion) on the avoidance of high-calorie snacks following reading gain-framed or loss-framed health messages. In Study 1 (N = 152) participants completed an autonomy, neutral, or heteronomy priming task, and read a gain-framed or loss-framed health message. In Study 2 (N = 242) participants read a gain-framed or loss-framed health message with embedded autonomy or heteronomy primes. In both studies, snacking intentions and behavior were recorded after seven days. In both studies, when autonomy was highlighted, the gain-framed message (compared to the loss-framed message) resulted in stronger intentions to avoid high-calorie snacks, and lower self-reported snack consumption after seven days. Study 2 demonstrated this effect occurred only for participants to whom the information was most relevant (BMI>25). The results suggest that messages promoting healthy dietary behavior may be more persuasive if the autonomy-supportive vs. coercive nature of the health information is matched to the message frame. Further research is needed to examine potential mediating processes.

“…Participants are typically required to record everything they eat over a period of several days, typically including both weekdays and weekend days; sometimes the ‘most representative’ days are selected for analysis. The primary advantages of diet diaries are that they provide a comprehensive assessment of dietary intake and, when completed properly, are less vulnerable to recall biases (35, 36). The primary limitation of these techniques is that they only provide an assessment of dietary intake over a period of a few days and the diet may be affected by the increased awareness of food consumption and may therefore not be representative of regular dietary habits (34).…”

Dietary Factors and Cognitive Decline

Cognitive decline is an increasingly important public health problem, with more than 100 million adults worldwide projected to develop dementia by 2050. Accordingly, there has been an increased interest in preventive strategies that diminish this risk. It has been recognized that lifestyle factors including dietary patterns, may be important in the prevention of cognitive decline and dementia in later life. Several dietary components have been examined, including antioxidants, fatty acids, and B vitamins. In addition, whole dietary eating plans, including the Mediterranean diet (MeDi), and the Dietary Approaches to Stop Hypertension (DASH) diet, with and without weight loss, have become areas of increasing interest. Although prospective epidemiological studies have observed that antioxidants, fatty acids, and B vitamins are associated with better cognitive functioning, randomized clinical trials have generally failed to confirm the value of any specific dietary component in improving neurocognition. Several randomized trials have examined the impact of changing ‘whole’ diets on cognitive outcomes. The MeDi and DASH diets offer promising preliminary results, but data are limited and more research in this area is needed.
