Higher fasting plasma FGF21 concentration is associated with lower ad libitum soda consumption in humans.

ABSTRACT:

Background

The hepatokine fibroblast growth factor 21 (FGF21) influences eating behavior and sugar consumption in rodent models. However, whether circulating FGF21 concentration is associated with food and soda intake in humans is still unclear.

Objective

We investigated whether fasting plasma FGF21 concentration is associated with objective measures of ad libitum food intake and soda consumption.

Methods

Healthy individuals [n = 109; 69 men, aged 34 ± 10 y; BMI (kg/m2): 30.4 ± 7.7; body fat by DXA: 30.5% ± 8.9%] with available plasma for hormonal measurements participated in an inpatient cohort study to objectively quantify ad libitum food and soda intake for 3 d using an automated and reproducible vending machine paradigm. Fasting plasma FGF21 concentration was measured by ELISA prior to ad libitum feeding.

Results

Fasting FGF21 concentration was inversely associated with daily soda intake (R = -0.22, P = 0.02 adjusted for demographics and anthropometrics), such that an interindividual difference of 200 pg/mL was associated with an average lower soda consumption by 68 kcal/d. Conversely, no associations were observed with total daily energy intake or macronutrient intake (all P > 0.17).

Conclusions

Higher plasma fasting FGF21 concentration is associated with lower ad libitum soda intake. Although this inverse correlation does not imply causation, the present results support the putative role of FGF21 in the reward pathways regulating sugar consumption in humans. This trial was registered at www.clinicaltrials.gov as NCT00342732.

Project description:PurposeA thrifty energy metabolism has been suggested in intrauterine growth restricted (IUGR) offspring. We characterized energy metabolism and substrate oxidation patterns in IUGR pigs in response to food restriction (FR) and refeeding (RFD).MethodsFemale pigs with low (L; 1.1 kg; n = 20) or normal birth weight (N; 1.5 kg; n = 24) were fed ad libitum after weaning. Half of L and N pigs were food restricted (R; LR, NR) from days 80 to 100 (57% of ad libitum) and refeed from days 101 to 131, while the remaining pigs were fed ad libitum (control, C). Using indirect calorimetry, carbohydrate and fat oxidation (COX, FOX), energy expenditure (EE) and balance (EB), resting metabolic rate (RMR) [all related to kg body weight(0.62) (BW)] and RQ were determined at 4 days before (day 76) and after (day 83) beginning of FR, 4 days before (day 97) and after (day 104) end of FR and 25 days after beginning of RFD (day 125). Body fat and muscle weights were determined at day 131.ResultsIn spite of higher relative food intake (FI), BW was lower in L pigs. In L pigs, physical activity was lower at age 76 and 83 days compared to N pigs. IUGR did not affect EE or RMR, but resulted in higher COX and lower FOX, causing greater and earlier onset of fat deposition. During FR, EE and RMR of R pigs dropped below that of C pigs, and BW gain was delayed by 30% irrespective of birth weight. In response to FR, COX decreased and FOX increased. During FR, in LR pigs FOX was ~50% of that in NR pigs. After 4 days, but not 25 days of RFD, EB and fat synthesis were higher in pigs previously subjected to FR, indicating early catch-up fat. In R pigs, BW and the abdominal fat proportion were lower at 131 days.ConclusionsDifferences in food intake and substrate oxidation pattern, but not in EE and RMR, between L and N pigs were reflected in higher body fat proportions but lower body and muscle weights in L pigs. Refeeding following FR was initially associated with increased FI, a more positive EB and a more intense stimulation of fat synthesis which did not persist after 25 days of refeeding.
