Brief Summary

Excessive eating of energy-dense foods and obesity are risk factors for a range of cancers. There are programs to reduce intake of these foods and weight loss, but the effects of the programs rarely last. This project tests whether altering the value of cancer-risk foods can create lasting change, and uses neuroimaging to compare the efficacy of two programs to engage the valuation system on a neural level. Results will establish the pathways through which the programs work and suggest specific treatments for individuals based on a personalized profile.

Detailed Description

Obesity and intake of certain foods increase cancer risk, but the most common treatment (behavioral weight loss programs) rarely produces lasting weight loss and eating behavior change, apparently because caloric restriction increases the reward value of food and prompts energy-sparing adaptations. Interventions that reduce the implicit valuation of cancer-risk foods (e.g., red meats, refined sugar) may be more effective. Emerging data suggest that behavioral response training and cognitive reappraisal training reduce valuation of such foods, which leads to decrease intake of these foods and weight loss. Internalized incentive value is reflected in a ventromedial prefrontal cortex (vmPFC) / orbitofrontal cortex valuation system, which encodes the implicit reward value of food and is central to a reinforcement cycle that perpetuates unhealthy eating. Thus, the vmPFC valuation system is a promising target for intervention because changes to the system might disrupt the unhealthy reinforcement cycle. Interestingly, various interventions influence the vmPFC through distinct pathways. Behavioral training alters motor input to valuation regions, whereas cognitive training relies on lateral prefrontal "top-down" regions. The proposed translational neuroscience experiment will compare the efficacy with which two novel treatments cause lasting change in food valuation, and whether a composite of theory-based baseline individual differences in relevant processes (such as response tendencies and cognitive styles) moderate treatment effects. We will randomize 300 overweight/obese adults who are at risk for eating- and obesity-related cancers to behavioral response training toward healthy foods and away from cancer-risk foods, a cognitive reappraisal intervention focused on cancer-risk foods, or non-food inhibitory control training. Aim 1 compares the efficacy and mechanisms of action of these two interventions to reduce valuation of cancer-risk foods relative to the active control condition, using neural, behavioral, self-report, and physiological measures of the process and outcomes. Aim 2 is to establish the temporal pattern and durability of the effects across time; food intake and habits, body fat, BMI, and waist-to-hip ratio will be measured pre, post, and at 3-, 6-, and 12-month follow-up. Aim 3 uses machine learning to build and validate a low-cost, easy-to-administer composite that predicts whether and for how long an individual is likely to respond to intervention, and to which treatment. We hypothesize that self-report measures specifically related to valuation (e.g., willingness-to-pay) and to intervention-specific pathways to valuation (e.g., behavioral response tendencies, cognitive style) will predict differential response. Discovering these individual differences will provide a practical, low-cost tool to help interventionists "match" a given person to an effective treatment for that person. This project is very innovative because no study has directly compared the distinct and common effects of these treatments on valuation, used brain imaging to study the mechanism of effects, tested whether these interventions produce a lasting change in food valuation and body fat, or built and validated a composite that moderates response.

Study Groups

Behavioral Response Training

In Arm 1 of Devaluing energy-dense foods for cancer-control, participants will complete computer delivered versions of the stop-signal, go/no-go, and dot-probe training tasks in 8 30-min biweekly visits to the lab, with breaks between training blocks in which participants sit with their eyes closed to allow consolidation of learning. Participants will also complete a weekly 15-min training task online from home. Total training time = 345 min. Training will involve 100 images of cancer risk foods that participants regularly eat, including red and processed meats; high-sugar foods; heavily salted, smoked, and pickled foods; fries, chips, and snacks with trans-fats, and 100 images of healthy foods that participants rate as palatable, including vegetables, fruits, nuts, and whole grains.

Group Type: EXPERIMENTAL

Devaluing energy-dense foods for cancer-control

Intervention Type: BEHAVIORAL

A 3-arm randomized controlled trial experiment study over 12 months. At baseline, participants will complete behavioral, neural, and self-report measures related to food, specifically measures of food valuation and of the proximal neural systems hypothesized to be linked to each of the 2 experimental arms. We will also measure food intake and body composition at baseline. Then participants will be randomized to one of 3 arms (2 experimental + 1 active control) for 8 30-min sessions to occur twice weekly at the University of Oregon for 30 days. At endpoint (\~1 month following baseline), all behavioral, neural, and self-report measures will be reassessed, as will eating, habit, and body composition measures. Follow-ups at 3, 6, and 12 months will assess all measures except neuroimaging.

Cognitive Reappraisal Training

Arm 2 of the Devaluing energy-dense foods for cancer-control intervention will be delivered via computer-assisted in-person training. Between baseline and endpoint sessions, participants will practice reappraisal on a computer, under close supervision of a facilitator, in 8 30-min twice-weekly individual sessions. During sessions, participants will practice cognitive reappraisal to reduce the value of cancer risk foods. Participants will also practice reappraisal of cancer risk foods on a computer at home, twice weekly for 15 minutes, for a total intervention time of contact of 345 minutes. The facilitator will review homework completed by participants and offer corrective feedback. The home practice is intended to promote generalization of use of this skill in the natural environment.

Generic Response Training

In Arm 3 (active control) of the Devaluing energy-dense foods for cancer-control intervention will be identical in duration and contact time to the behavioral response training described above (345 min total), but will involve nonfood images (birds and flowers), as described in the pilot trial. Participants will be informed that this intervention is designed to improve response inhibition, which should lead to eating change and weight loss given that impulsivity increases the risk for overeating, ensuring the credibility of the control arm.
