The misperception that eating fat causes weight gain may lead consumers to avoid nutritious foods like avocados, which are primarily composed of beneficial monounsaturated fats.”

Hass Avocado Inclusion in a Weight Loss Diet Supported Weight Loss and Altered Gut Microbiota: A 12 Week Randomized Parallel-controlled Trial published in Current Developments in Nutrition

This study was a randomized parallel-controlled trial including 51 healthy participants 20-60 years old and of BMI 27-35kg/m2. Each were randomly assigned to a hypocaloric meal plan either with or without one fresh Hass avocado per day for 12 weeks. They also all received biweekly counseling from an RD. The hypocaloric diet was defined as a 500 calorie deficit, consisting of 30-35% calories from fat, 15-20% from protein and 45-55% from carbs. This study was supported by the Hass Avocado Board as part of the Love One Today® education program.

Tune in to this episode to learn key takeaways from this study about:

  • body weight and composition
  • satiety
  • gut microbiome
  • inflammation
  • limitations
  • future research

As in all research, the study has its limitations, so more research is needed to generalize the results to all people, however, these findings support the growing body of evidence connecting eating avocados and a positive impact on body weight and satiety.

This study demonstrated that including one Hass avocado daily in a hypocaloric diet not only supported weight loss efforts, but also offered additional potential metabolic and anti-inflammatory benefits.”

We know avocados are a good source of dietary fiber (3g per one third of a medium avocado), making them a great fresh fruit option to help boost fiber intake.”
