Power Of Food Scale

Background Greater sensitivity to food rewards and higher levels of impulsivity (and an interaction between these variables, termed “reinforcement pathology”) have been associated with obesity in cross-sectional studies. Less is known regarding how these constructs may impact attempts at weight loss or longer-term weight loss maintenance. Methods We provided 75 adults (69%Female, 84%White, age = 50.8y, BMI = 31.2kg/m2) with a 3-month Internet-based weight loss program and assessed weight, food reward sensitivity (via the Power of Food Scale [PFS]), and impulsivity (via Go No-Go [GNG] and Delay Discounting [DD] computer tasks) at baseline and at Months 3, 6, 9, and 12. No additional intervention was provided Months 3–12. Multi-level mixed-effect models were used to examine changes in PFS, GNG, and DD over time and associations between these measures and weight loss/regain. Results Participants lost 6.0±1.1kg Months 0–3 and regained 2.4±1.1kg Months 3–12. Across time points, higher PFS scores were associated with higher weight, p = .007; however, there were no significant associations between GNG or DD and weight nor between the interactions of PFS and GNG or DD and weight, ps>.05. There were significant decreases from Months 0–3 in PFS, GNG, and DD, ps < .05; however, neither baseline values nor changes were significantly associated with weight change and there were no significant associations between the interactions of PFS and GNG or DD and weight change, ps>.05. Conclusion Results demonstrated an association between food reward sensitivity and weight. Further, decreases in both food reward sensitivity and impulsivity were observed during an initial weight loss program, but neither baseline levels nor improvements were associated with weight change. Taken together, results suggest that the constructs of food reward sensitivity, impulsivity, and reinforcement pathology may have limited clinical utility within behavioral weight management interventions. Future intervention studies should examine whether food-related impulsivity tasks lead to a similar pattern of results.

Type Of Surgery

Changes in food preferences after bariatric surgery may alter its effectiveness as a treatment for obesity. We aimed to compare food reward for a comprehensive variety of food categories between patients who received a sleeve gastrectomy (SG) or a Roux-en-Y gastric bypass (RYGB) and to explore whether food reward differs according to weight loss. In this cross-sectional exploratory study, food reward was assessed using the Leeds Food Preference Questionnaire (LFPQ). We assessed liking and wanting of eleven food categories. Comparisons were done regarding type of surgery and Total Weight Loss (TWL; based on tercile distribution). Fifty-six patients (30 SG and 26 RYGB) were included (women: 70%; age: 44.0 (11.1) y). Regarding the type of surgery, scores were not significantly different between SG and RYGB, except for &lsquo;non-dairy products &ndash; without color&rsquo; explicit liking (p = 0.04). Regarding TWL outcomes, explicit liking, explicit wanting and implicit wanting, scores were significantly higher for Good responders than Low responders for &lsquo;No meat &ndash; High fat&rsquo; (post-hoc corrected p-value: 0.04, 0.03 and 0.04, respectively). Together, our results failed to identify major differences in liking and wanting regarding the type of surgery and tended to indicate that higher weight loss might be related to a higher reward for high protein-content food. Rather to focus only on palatable foods, future studies should also consider a broader range of food items, including protein reward.

Weight Loss Program

163 Background: Obesity is associated with higher breast cancer recurrence and death, and poorer health and quality of life. African-American (AA) women have the highest prevalence of obesity, obesity-related comorbidities, and breast cancer mortality compared with other racial/ethnic groups. Weight loss after breast cancer diagnosis may lower rates of recurrence and improve fitness, fatigue, and quality of life. Methods: This 6-month randomized controlled trial pilot-tests the use of a Fitbit activity tracker (Fitbit only group) versus Fitbit plus SparkPeople, a free web-based weight loss program (combined group) among 70 AA breast cancer survivors. Paired t-tests assess changes from baseline to 6-months among each participant in primary (weight, body mass index [BMI], percent body fat) and secondary (24-hour caloric intake, daily number of steps, quality of life, self-monitoring strategies, self-efficacy) outcomes. Two-group t-tests assess differences in outcomes between the two groups. Results: Currently, 36 of 46 (78.3%) eligible participants have enrolled and completed baseline assessments. Mean age of participants is 61.7 years (SD 8.7) and mean BMI is 36.9 (SD 7.0). Analyses of the first 25 participants who completed 3-month assessments (Fitbit only N = 12; combined group N = 13) show significant weight loss in both groups; Fitbit only: mean weight change -6.73 pounds, SD 4.61, p < 0.001; mean BMI change -0.96 kg/m2, SD 0.84, p = 0.002; combined group: mean weight change -5.95 pounds, SD 5.84, p = 0.003; mean BMI change -1.03 kg/m2, SD 0.77, p < 0.001. All participants significantly increased tracking of diet (Fitbit only p = 0.016; combined group p < 0.001) and physical activity (Fitbit only p < 0.001; combined group p = 0.001). Though not significant, combined group participants showed greater increases in self-efficacy for eating healthy and reducing fat and calories, and increases in daily steps (+1308 vs. +285 for Fitbit only group). Preliminary analyses show no statistically significant difference in changes in outcomes from baseline to 3 months between the two groups. Conclusions: Both programs show potential as convenient and efficient weight loss methods for African-American breast cancer survivors. Clinical trial information: NCT02699983.

Aims: This study assessed the patterns of weight change in response to surgical treatment for obesity. Methods: Vertical Banded Gastroplication (VBG) was performed during the period 1994–2000. Patients were required to follow a liquid diet (8oo kcals) for 12 weeks before surgery. The same diet plus a multivitamin capsule (Forceval) was followed for 12 weeks postoperatively, after which normal foods were introduced. Data from 23 patients, 16 women and 7 men, aged 33–63 years (mean, SD; 42±8yrs), with BMI from 38 to 69 kg/m2 (52.5 ± 8.1 kg/m2) at the time of the surgery were available for analysis. Follow up was 3 to 7 years (mean 4 years). Results: An initial weight loss of 44.4 ± 24.3 kg (min 11.5, max 110.5 kg) was reached during the first two years (mean BMI decrease 15.8 kg/m2). However a regain in weight (36% of the initial weight loss = 5.6 kg/m2) up to 3 to 7 years after surgery was usual. Average annual regain was 13.6 kg (n=17), 9.45 kg (n=11) and 0.8 kg (n=8) during the 3rd, 4th and 5th year after surgery). Five participants reached a BMI below 30 but only one, BMI<25, has maintained all the weight loss after 5 years. Conclusions: Weight loss following VBG ceased after two years with a subsequent substantial weight regain. Auxiliary therapies to counteract weight regain are necessary after VBG.

Cumulative Change

Overweight and obese children in low-income households have limited access to weight loss programs. Low-cost programs should be evaluated in this population. The objective of the current study is to determine weight change among 7 to 17-year-old participants in Take Off Pounds Sensibly (TOPS), a national, low-cost weight loss program. This nonconcurrent prospective study analyzes the cumulative change in weight z-score for overweight and obese children and adolescents who joined TOPS from 2008 to 2011 and consecutively renewed their annual membership. The study includes 586 individuals. At 1-year, cumulative mean (SD) weight z-score change was −0.13 (31). In general, mean change in weight z-scores was no different in subsequent years. Mean weight z-score of children and adolescent TOPS participants who renew their program membership decreased significantly in the first year. Randomized controlled trials should prospectively evaluate this program in children and adolescents.

29 men and 82 women who had achieved at least a 15-lb. weight loss in a 20-wk. cognitive-behavioral treatment program for obesity were asked 6 to 10 yr. after treatment about their current weights and January 1 weights for the past five years. Four types of weight change indices were then developed to ascertain whether or not the patients had maintained their postprogram weight losses since leaving treatment. Comparisons of pre- and postprogram mean weight differences indicated that the patients had gained an average of 7.15 lb. (3.24 kg) by 1983, but there had not been a mean increase in weight since an earlier follow-up in 1978. Importantly, 32.4% reported 1983 weights below their postprogram weights, and there were no mean differences between the sexes with respect to weight changes for either 1978 or 1983. A weight index based upon percentages of weight gain since leaving treatment indicated that 40.5% had gained back more than 67% of weight that they had lost during treatment. Inspection of 90 patients' weight fluctuations over the past five years above or below their postprogram weights showed 25 distinct patterns. Each of the four weight-change indices gave different perspectives about the patients' abilities to manage their weights over time. The complexity of employing different weight-change indices for evaluating the long-term efficacy of cognitive-behavioral treatment programs for obesity was discussed.

Food reward (i.e., liking and wanting) has been shown to decrease after different types of weight management interventions. However, it is unknown whether specific dietary modalities (continuous (CER) vs. intermittent (IER) energy restriction) have differing effects on liking and implicit wanting after weight loss (WL) and whether these changes are sustained after 1-year of no-contact. Women with overweight or obesity (age 18–55 years) were randomly allocated to controlled-feeding CER (25% daily energy restriction) or IER (alternating ad libitum and 75% energy restriction days). Study visits were conducted at baseline, post-WL (to ≥5% WL within 12 weeks) and 1-year post-WL. The main outcomes were liking and implicit wanting for 4 categories of common food varying in fat and taste assessed by the Leeds Food Preference Questionnaire. Linear mixed models were conducted on the 30 participants achieving ≥5% WL and 15 returners. After an initial WL of −5.1 ± 0.2 kg, after 1-year 2.6 ± 0.5 kg were regained. Liking but not wanting decreased after WL. Food reward after 1-year did not differ from baseline, but the high loss to follow-up prevents generalization. IER and CER did not differ in their effects on food reward during WL or at 1-year follow-up.

Power Of Food Scale

Background: Eating in the absence of hunger (EAH) measures intake of highly palatable, highly processed foods when sated, and may reflect food reward sensitivity. However, it is unknown whether EAH occurs in the presence of low-processed, nutrient-dense foods, and the relationship of self-reported food reward sensitivity with EAH during pregnancy has not been examined.Objective: This study tested whether EAH differs for highly-processed (HP) versus low-processed (LP) foods in pregnant women and examined relationships of EAH with self-reported food reward sensitivity and impulsivity.Design: Women in their 2nd trimester (n=46) enrolled in a counterbalanced crossover study in which they completed two EAH conditions following a standardized meal. Participants completed the Power of Food Scale (PFS), the modified Yale Food Addiction Scale (m-YFAS), and the Barratt Impulsiveness Scale (BIS). EAH energy intake (EAH-kcal) and proportion consumed (EAH-%) was measured overall and separately for sweet and savory test foods. Results: EAH-% was similar across conditions (16.3% ± 1.1% HP versus 17.9% ± 1.2% LP, P = 0.74), resulting in 347.7 ± 49.0 kcal greater energy intake in the HP versus LP condition (P &lt; 0.001). PFS was not significantly associated with EAH; m-YFAS was positively associated with EAH-kcal and EAH-% of savory foods, and BIS was positively associated with EAH-kcal and EAH-% overall, and with EAH-% of sweet foods (p &lt; 0.05). There was little evidence of an interaction of BIS with PFS or m-YFAS.Conclusions: Findings demonstrate that EAH in pregnant women correlates with self-reported food reward sensitivity and occurs for both highly processed and low-processed foods. Self-control did not modify the positive association of food reward sensitivity with eating beyond satiation in this sample.
