Abstract Background/objectives Numerous hepatokines are involved in inter-organ cross talk regulating tissue-specific insulin sensitivity. Adipose tissue lipolysis represents a crucial element of adipose insulin sensitivity and is substantially involved in long-term body weight regulation after dietary weight loss. Thus, we aimed to analyze the impact of the hepatokine Fetuin-B in the context of weight loss induced short- and long-term modulation of adipose insulin sensitivity. Subjects/methods 143 subjects (age > 18; BMI ≥ 27 kg/m2) were analyzed before (T-3) and after (T0) a standardized 12-week dietary weight reduction program. Afterward, subjects were randomized to a 12-month lifestyle intervention or a control group. After 12 months (T12) no further intervention was performed until 6 months later (T18) (Maintain-Adults trial). Tissue-specific insulin sensitivity was estimated by HOMA-IR (predominantly liver), ISIClamp (predominantly skeletal muscle), and free fatty acid suppression during hyperinsulinemic-euglycemic clamp (FFASupp) (predominantly adipose tissue). Fetuin-B was measured at all concomitant time points. Results Circulating Fetuin-B levels correlated significantly with estimates of obesity, hepatic steatosis as well as HOMA-IR, ISIClamp, FFASupp at baseline. Fetuin-B decreased during dietary weight loss (4.2 (3.5–4.9) vs. 3.8 (3.2–4.6) µg/ml; p = 2.1 × 10−5). This change was associated with concomitant improvement of HOMA-IR (r = 0.222; p = 0.008) and FFASupp (r = −0.210; p = 0.013), suggesting a particular relationship to hepatic and adipose tissue insulin sensitivity. Weight loss induced improvements of insulin resistance were almost completely preserved until months 12 and 18 and most interestingly, the short and long-term improvement of FFASupp was partially predicted by baseline level of Fetuin-B. Conclusions Our data suggest that Fetuin-B might be a potential mediator of liver-adipose cross talk involved in short- and long-term regulation of adipose insulin sensitivity, especially in the context of diet-induced weight changes.

Abstract Background Certain eating behaviors are common among women with obesity. Whether these behaviors influence outcomes in weight loss programs, and whether such programs affect eating behaviors, is unclear. Methods Our aim was to examine the effect of baseline eating behaviors on intervention adherence and weight among postmenopausal women with overweight or obesity, and to assess intervention effects on eating behaviors. Four hundred and 39 women (BMI ≥25 kg/m2) were randomized to 12 months of: i) dietary weight loss with a 10% weight loss goal (‘diet’; n = 118); ii) moderate-to-vigorous intensity aerobic exercise for 225 mins/week (‘exercise’; n = 117); iii) combined dietary weight loss and exercise (‘diet + exercise’; n = 117); or iv) no-lifestyle change control (n = 87). At baseline and 12 months, restrained eating, uncontrolled eating, emotional eating and binge eating were measured by questionnaire; weight and body composition were assessed. The mean change in eating behavior scores and weight between baseline and 12 months in the diet, exercise, and diet + exercise arms were each compared to controls using the generalized estimating equation (GEE) modification of linear regression adjusted for age, baseline BMI, and race/ethnicity. Results Baseline restrained eating was positively associated with change in total calories and calories from fat during the dietary intervention but not with other measures of adherence. Higher baseline restrained eating was associated with greater 12-month reductions in weight, waist circumference, body fat and lean mass. Women randomized to dietary intervention had significant reductions in binge eating (− 23.7%, p = 0.005 vs. control), uncontrolled eating (− 24.3%, p < 0.001 vs. control), and emotional eating (− 31.7%, p < 0.001 vs. control) scores, and a significant increase in restrained eating (+ 60.6%, p < 0.001 vs. control); women randomized to diet + exercise reported less uncontrolled eating (− 26.0%, p < 0.001 vs. control) and emotional eating (− 22.0%, p = 0.004 vs. control), and increased restrained eating (+ 41.4%, p < 0.001 vs. control). Women randomized to exercise alone had no significant change in eating behavior scores compared to controls. Conclusions A dietary weight loss intervention helped women modify eating behaviors. Future research should investigate optimal behavioral weight loss interventions for women with both disordered eating and obesity. Trial registration NCT00470119 (https://clinicaltrials.gov).

Background: As the epidemic of obesity in the United States steadily worsens, black women are disproportionately affected. Diminished insulin sensitivity has been linked with obesity and heightened risk of subsequent type 2 diabetes (T2D) and cardiovascular disease (CVD). Hypothesis: We propose that a decrease in fat mass achievable by weight loss intervention at the worksite improves insulin sensitivity in overweight black women. Methods: Fifty-four overweight black women [age 45±10 years (mean±SD), BMI range 25.9 to 54.7 kg/m 2 ] completed a 6-month program that included web-based nutrition information and/or dietitian counseling and access to exercise rooms near their work areas. All participants were advised to reduce daily caloric intake by 500 kcal and instructed to increase daily activity by 5,000 steps, measured by pedometer, above baseline readings. The following measurements were performed: weight, total fat mass by dual-energy X-ray absorptiometry, and insulin sensitivity index (S I ) calculated from the minimal model. Repeat of all measurements was performed at 6 months. Results: Baseline S I (median 3.0 liter/mU -1 •min -1 , range 0.74 to 7.58 liter/mU -1 •min -1 , with lower values signifying insulin resistance) was negatively associated with fat mass (r= -0.584, P<0.001) independent of age. Significant reductions in weight (92.6±18.1 to 91.1±18.9 kg, P<0.01) and fat mass (40.8±12.4 to 39.4±12.6 kg, P<0.01) were determined for subjects completing the program. Reduction in fat mass following completion of the program was associated with an increase in S I (r= -0.293, P=0.032). When analyzed by tertiles of fat mass change (Figure), compared to the tertile with net fat mass gain (far left bar), the two tertiles with net fat mass loss had significantly improved insulin sensitivity (higher S I ). Conclusions: Even modest fat mass reduction in overweight non-diabetic black women with a combination of diet and exercise can improve insulin sensitivity, which has the potential to reduce or delay the onset of T2D and CVD.
