Background Dietary habits are critical determinants of health and especially of cardiometabolic risk status. Previous studies have examined the relationship between breakfast consumption and indices of obesity, with conflicting findings. Such discrepancy may be owed to the use of surrogate measures of adiposity such as body mass index. Furthermore, it is unknown whether frequency of breakfast consumption is associated with different patterns of regional body fat distribution. Objective In this study, we aimed at investigating the association between frequency of breakfast consumption and body fat distribution. Methods We compiled data from 184 individuals (64% males, mean age 35.8±12.6 years, ranging from 18 to 63 years old) who participated in research studies performed in the Mayo Clinic Cardiovascular/Sleep Laboratory from 2005 to 2019 and underwent whole body dual‐energy X‐ray absorptiometry (DXA) for body composition. Breakfast eating habits were assessed by questionnaire and frequency of consumption was determined as number of times per week (range 0 to 7). Responses were recoded as low frequency (0 to 2 times/week), middle frequency (3 to 4 times/week), and high frequency (5 to 7 times/week). Measures of height and weight were collected to compute body mass index (BMI, kg/m 2 ). Total body fat percentage, fat mass, and lean mass were obtained from DXA. Regions of interest were manually adjusted with the DXA software to quantify abdominal fat and lower body fat. Abdominal fat/total body fat and lower body fat/total body fat ratios were calculated. Results Low frequency of breakfast consumption was reported by 14% of the subjects (n=26), while 18% (n=34) reported middle‐frequency of consumption. The proportion of men/women (p=0.1) and BMI values (p=0.78) were similar across breakfast eating categories. Compared to those who had breakfast with high‐frequency, those who ate it less frequently were younger (p=0.038). In age, sex, and BMI‐adjusted analysis, low‐frequency of breakfast consumption was significantly associated with greater abdominal fat mass (standardized beta=0.11, 95% CI 0.09‐ 1.29, p=0.024) and higher abdominal fat/total body fat ratio (standardized beta=0.16, 95% CI 0.003–0.024, p=0.013). Total body fat percentage (p=0.26), fat mass (p=0.26), and lean mass (p=0.22) were not associated with frequency of breakfast consumption. Similarly, no relations were seen with lower body fat (p=0.85) or lower body fat/total body fat ratio (p=0.51). Conclusion Our study showed that infrequent breakfast consumption is selectively associated with greater abdominal fat mass. As accumulation of fat in the abdominal depot is a more robust predictor of adverse outcomes than total adiposity, these findings suggest that abdominal fat may mediate the increased cardiometabolic risk previously observed in conjunction with infrequent breakfast consumption.
