Despite previous suggestions, daily avocado consumption for six months did not decrease visceral adipose tissue volume in individuals with elevated waist circumference.
Randomised Controlled Trial Avocado
The HAT Trial was a multicenter, randomized, controlled study designed to observe the effects of consuming one large avocado per day for six months on free-living individuals with an increased waist circumference. The primary measure of effect was the change in visceral adipose tissue volume, which was measured through magnetic resonance imaging. Other conditions related risk factors associated with cardiometabolic disorders were surveyed as secondary and additional endpoints.
In results analysis, there was no significant alteration in visceral adipose tissue volume between the Avocado Supplemented and Habitual Diet Groups. No noteworthy differences were noticed in the secondary outcomes including hepatic fat fraction and certain components of the metabolic syndrome. Of the extra outcome measures, small but significant reductions were seen in total and low-density lipoprotein cholesterol in the Avocado Supplemented compared to the Habitual Diet Group. Changes in body weight, body mass index, insulin concentration and other measured factors were very similar between both groups, showing no considerable change due to avocado consumption.

Consumption of one avocado per day can potentially reduce visceral adiposity and subsequently decrease the risk of diabetes and cardiovascular disease.
Randomised Controlled Trial Avocado Cardiometabolic Disease Cardiovascular Disease
The Habitual Diet and Avocado Trial was a multicenter, randomized, controlled study that evaluated the impact of daily avocado consumption over a period of six months. The experiment involved a large and diverse cohort. Participants were required to incorporate a daily avocado into their diet as a substitute for their regular dietary intake, notably those devoid of avocado consumption. Their progress was measured using magnetic resonance imaging (MRI) to ascertain the potential decrease in visceral adiposity, with individuals with increased waist circumference being the primary focus of the study. Additional measures such as hepatic lipid content, plasma lipid profiles, blood pressure and high sensitivity C-reactive protein were also part of the evaluation.
The study showed promising results in terms of weight control and reduction of visceral adiposity among participants. Initial results suggest that the sense of satiety post avocado consumption may subsequently lead to an overall decrease in energy intake. Moreover, the daily consumption of avocados was observed to not only reduce visceral fat but also display potential benefits impacting cardiometabolic disease risk. The benefits of avocado consumption were notably apparent among a cohort with an increased waist circumference, thus confirming the potential health benefits of avocados in weight management and risk reduction of obesity-related diseases.

Adzuki bean paste consumption can reduce fat accumulation in rats by lowering energy intake and altering gut microbiota composition.
Animal Study Gut Microbiota Obesity
The study evaluated the impact of adzuki bean paste (ABP) on visceral fat accumulation in rats by administering different doses of ABP - 30% and 58.9% in their diets for a period of 28 days. ABP, being a good source of indigestible carbohydrates with fiber and resistant starch, forms an influential part of the rats' diet. The daily dietary energy intake was observed during this period, with particular attention to fecal lipid and fecal acidic sterol excretions, which were found to be increased in a dose-dependent manner. Certain observations within the body of the rats, including the condition of cecal content and fecal moisture, were also monitored.
In discussing the results of administrating ABP in the diet, it was observed that visceral fat accumulation and serum lipid levels were reduced. Both groups of rats - those given a diet with 30% ABP and those with 58.9% ABP - showed significantly higher cecal acetic, propionic, and n-butyric acids and lowered cecal pH, regardless of the ABP dose. The ABP diet also reflected altered microbial community data, with higher alpha-diversities than a control group. The study further revealed through cecal bacterial 16S rRNA gene sequencing that the ABP supplemented diets also impacted the ratio of two types of bacteria, Firmicutes, and Bacteroidetes. The findings hence suggest that the cecal fermentation of fiber and resistant starch in ABP was instrumental in reducing fat accumulation.
