Short-term wellcontrolled clinical trials suggest that regular avocado consumption favorably affects body weight, visceral adiposity, and satiety.\u003Cbr>METHODS AND RESULTS: The HAT Trial (Habitual Diet and Avocado Trial) was a multicenter, randomized, controlled parallel-arm trial designed to test whether consuming 1 large avocado per day for 6months in a diverse group of free-living individuals (N=1008) with an elevated waist circumference compared with a habitual diet would decrease visceral adiposity as measured by magnetic resonance imaging. Secondary and additional end points related to risk factors associated with cardiometabolic disorders were assessed. The primary outcome, change in visceral adipose tissue volume during the intervention period, was not significantly different between the Avocado Supplemented and Habitual Diet Groups (estimated mean difference (0 .017 L [−0 .024L, 0.058L], P=0 .405). No significant group differences were observed for the secondary outcomes of hepatic fat fraction, hsCRP (high-sensitivity C-reactive protein), and components of the metabolic syndrome. Of the additional outcome measures, modest but nominally significant reductions in total and low-density lipoprotein cholesterol were observed in the Avocado Supplemented compared with the Habitual Diet Group. Changes in the other additional and post hoc measures (body weight, body mass index, insulin, very low-density lipoprotein concentrations, and total cholesterol:high-density lipoprotein cholesterol ratio) were similar between the 2 groups.\u003Cbr>CONCLUSIONS: Addition of 1 avocado per day to the habitual diet for 6 months in free-living individuals with elevated waist circumference did not reduce visceral adipose tissue volume and had minimal effect on risk factors associated with cardiometabolic disorders.\u003Cbr>REGISTRATION: URL: [https://clinicaltrials.gov](https://clinicaltrials.gov) ; Unique identifier: NCT03528031.\u003Cbr>Key Words: avocado ■ habitual diet ■ randomized clinical trial ■ risk factors for cardiometabolic disorders ■ visceral fat |  |\n| --- | --- |\n| In the United States, ≈60% of adults have visceral\u003Cbr>adiposity, defined as a waist circumference of ≥40 inches for women and ≥35 inches for men.1,2 Visceral adiposity is associated with elevated risk of type 2 diabetes, insulin resistance, systemic inflammation, cardiovascular disease, and all-cause mortality.3–6 | To reduce the burden of these chronic disorders, strategies are needed to prevent the development of visceral adiposity.\u003Cbr>Independent of total caloric intake, diet quality has been reported to affect visceral adiposity.7–9 One food of recent interest is avocados.
