A Low-Fat Vegan Plant-Based Diet: Good for Your Wallet and Your Health
Nutrition | Home Economics
With grocery prices remaining stubbornly high, many people are seeking ways to cut costs while maintaining a healthy diet. According to new research published in JAMA Network Open by the Physicians Committee for Responsible Medicine, switching to a low-fat vegan diet could be the answer. Not only does it offer significant cost savings, but it also provides numerous health benefits that could improve quality of life.
Switching to a low-fat vegan diet can save over $650 annually compared to a standard American diet and $870 compared to a Mediterranean diet. It improves health, reduces grocery bills, and supports sustainability—a win for your wallet, your well-being, and the planet!
Substantial Cost Savings
The study found that a low-fat vegan diet, based on fruits, vegetables, grains, and beans, can cut daily food costs by 19 percent, or $1.80, compared to a standard American diet that includes meat, dairy, and other animal products. Over the course of a year, this adds up to more than $650 in savings. When compared to the popular Mediterranean diet, which is often touted as both healthy and cost-effective, the vegan diet shines even brighter—saving $2.40 per day or more than $870 annually.
The researchers attribute these savings primarily to eliminating costly items like meat, dairy, and added fats, which accounted for reductions of $2.90, $0.50, and $0.50 per day, respectively. While vegan diets may increase spending slightly on vegetables, grains, and plant-based meat alternatives, these costs are significantly outweighed by the overall reduction in grocery bills.
Health Benefits That Save Lives
Beyond financial savings, the research highlights the health benefits of a low-fat vegan diet. According to Dr. Hana Kahleova, the study’s lead author and director of clinical research at the Physicians Committee for Responsible Medicine, a vegan diet could help prevent or improve chronic conditions such as obesity, type 2 diabetes, and heart disease. These conditions are not only costly to treat but also diminish quality of life.
The study compared a low-fat vegan diet to a Mediterranean diet, which includes fish, low-fat dairy, legumes, and extra-virgin olive oil. Participants who followed the vegan diet for 16 weeks experienced better outcomes in weight loss, body composition, insulin sensitivity, and cholesterol levels than those on the Mediterranean diet.
Study Methodology
This groundbreaking research is a secondary analysis of a previous Physicians Committee study. The study randomly assigned participants to follow either a low-fat vegan diet or a Mediterranean diet for 16 weeks. After a four-week washout period, participants switched to the opposite diet for another 16 weeks. Both diets were unrestricted in calories, allowing participants to eat until they felt satisfied.
To calculate food costs, dietary records from the participants were linked to the U.S. Department of Agriculture Thrifty Food Plan, 2021—a comprehensive database of national food prices. The findings showed that plant-based eating isn’t just healthy and sustainable; it’s also budget-friendly.
A Sustainable Solution
Switching to a low-fat vegan diet has benefits that go beyond individual savings and health. Plant-based diets have a lower environmental impact, requiring fewer resources like water and land compared to animal agriculture. By adopting a vegan lifestyle, individuals can contribute to a more sustainable food system while reducing their grocery bills.
Takeaways for Consumers
For those considering a dietary change, the financial and health incentives of a low-fat vegan diet are hard to ignore. By replacing meat and dairy products with fruits, vegetables, grains, and beans, families can save hundreds of dollars annually while improving their health.
Dr. Kahleova emphasizes the long-term benefits: “A vegan diet won’t just save money; it could save lives.”
Whether you are motivated by the potential cost savings, the promise of better health, or the desire to reduce your environmental footprint, a low-fat vegan diet offers a practical and impactful solution.
