With keto, intermittent fasting, the GOLO diet and more, you'd think there isn't room for yet another trendy eating style, but alas, there is. Enter the Nutritarian Diet, which emphasizes plant-based meals — and knowing the Nutritarian Diet's pros and cons can help you decide if it's right for you.
Video of the Day
Turns out, there may be a reason for the hype: This program is ranked fifth among the best commercial diet plans for 2022, according to U.S. News & World Report, sitting alongside the likes of WW (Weight Watchers) and Jenny Craig.
But what is this new-ish diet, and what does it entail? And will it actually help you move the number on the scale? Here's our Nutritarian Diet review, including how it works, the pros and cons and whether you should try it.
What Is the Nutritarian Diet?
The eating plan was created by Joel Fuhrman, MD, a family doctor who has published a number of books on diet and health. And according to U.S. News' reporting, the diet itself is based on four core principles:
- Nutrient density: Paying attention to the concentration of nutrients per calorie of food
- Nutrient adequacy: Getting all of the nutrients your body requires
- Toxin avoidance: Limiting chemicals, toxins and other harmful substances that can be found in certain foods
- Hormonal favorability: Opting for low-glycemic-index foods and limiting animal proteins to promote favorable hormone levels
What You Can (and Can’t) Eat on the Nutritarian Diet
- Eat your G-BOMBS (Greens, Beans, Onions, Mushrooms, Berries and Seeds).
- Avoid snacking.
- Just say no to salt, sugar or oil that's added to food.
- Replace one meal a day with a salad.
Foods to Eat
- Vegetables: These make up the base of the food pyramid. Half should be cooked and half should be raw. In total, vegetables should make up 30 to 60 percent of your total calories for the day.
- Fresh fruits: Fruit should make up 10 to 40 percent of your total calories each day.
- Beans and legumes: Legumes should make up 10 to 40 percent of your total calories each day.
- Seeds, nuts, avocados: These foods containing beneficial fat should make up 10 to 40 percent or less of your total calories for the day.
- Whole grains and potatoes: These foods should account for 20 percent or less of your total daily calories.
If there are calories remaining in your day, the website states you can eat the following minimally processed foods (if desired), though they shouldn't account for more than 5 percent of your total daily caloric intake:
- Coarsely-ground or sprouted whole-grain breads or cereals
- Limited amounts of animal products
Foods to Limit
The following foods should be limited to less than 10 percent of your total calories:
- Oil (even olive oil)
- Dairy products
- Wild or naturally raised animal products like meat and fish
Foods to Avoid
The diet recommends steering clear of the following products as much as possible:
- Sugar and other sweeteners
- Commercial and processed meats
- Processed foods
- Added salt
Will You Lose Weight?
Given the diet's focus on eating minimally processed, nutritious foods while also cutting back on added sugars, fats and salt, it's possible that you'll lose weight on the plan, according to January 2020 research in the American Journal of Lifestyle Medicine.
There's also a more restrictive version of the Nutritarian Diet called the 10 in 20: Dr. Fuhrman's Lose 10 Pounds in 20 Days Detox Program.
However, such a fast rate of weight loss typically isn't safe or sustainable, according to the Mayo Clinic, which instead recommends weight loss at a pace of 1 to 2 pounds per week.
Nutritarian Diet Pros
The Nutritarian Diet has its pros and cons. Here are some potential perks of the program:
1. It Encourages Nutritious Eating
The eating style emphasizes plant-based, minimally processed and nutrient-dense foods like fruits and vegetables, all of which support overall wellbeing, according to the Mayo Clinic.
As a bonus, these foods are packed with fiber, an essential nutrient that helps promote good digestion and normalizes bowel movements, according to the Mayo Clinic. Fiber can also be beneficial for your heart health and blood sugar levels (more on those later).
2. It May Support Heart Health
Indeed, an October 2015 study in the American Journal of Lifestyle Medicine found that following the Nutritarian Diet — also referred to as a nutrient-dense, plant-rich diet — helped lower people's blood pressure, cholesterol and triglyceride levels, all of which may decrease risk for cardiovascular disease.
3. It Can Help Regulate Blood Sugar
A high-fiber diet can also help regulate digestion to avoid blood sugar spikes, according to the Mayo Clinic.
The diet has likewise been linked to better glycemic control — in other words, more stable blood sugar levels — in people with diabetes, according to the 2020 American Journal of Lifestyle Medicine research.
4. It Can Support Weight Loss
As mentioned above, the diet's emphasis on whole plant foods and lack of processed goods may all support weight loss, according to the Mayo Clinic.
The 2015 American Journal of Lifestyle Medicine research also found that following an eating program similar to the Nutritarian Diet led to sustained weight loss in people with obesity.
Regular exercise is also an important component of any weight-loss plan, according to the Mayo Clinic, so consider adding physical activity to your nutritarian lifestyle.
5. It May Lower Your Risk for Chronic Disease
Altogether, these potential benefits may help decrease your risk for developing chronic diseases like cancer, heart disease and diabetes, according to the 2020 American Journal of Lifestyle Medicine research.
Nutritarian Diet Cons
As stated, Dr. Fuhrman's diet has its pros and cons. Here are the potential drawbacks:
1. It Limits Certain Nutritious Foods
The diet limits beneficial foods like fish and olive oil. Both foods are staples of the Mediterranean diet, which experts and research have deemed one of the best diets for overall wellbeing due to its non-restrictive guidelines and heart-healthy ingredients, according to the Mayo Clinic.
These foods are also rich in beneficial fats and omega-3s, both of which can support heart health, per the American Heart Association. But instead, the Nutritarian Diet encourages getting these nutrients through supplements, according to the website.
Despite this suggestion, however, it's really best to fulfill your nutritional needs with whole foods, not supplements, per the Mayo Clinic.
Talk to your doctor before trying any supplement, as the FDA doesn't require these products to be proven safe or effective before they're sold, so there’s no guarantee that any supplement you take is safe, contains the ingredients it says it does or produces the effects it claims.
2. It May Not Be Sustainable
Because the diet restricts certain food groups and requires calorie budgeting, it may not be easy to stick to in the long run, per the Mayo Clinic.
3. It May Not Support Long-Term Weight Loss
Similarly, diets that are restrictive, boring or don't include foods you love can be hard to follow in the long term, according to the Mayo Clinic. And if a diet isn't sustainable, it's not likely you'll maintain weight loss.
4. It Can Come at a Cost
The diet's website encourages buying a membership, which gives you access to meal plans, events, a health tracker and more. But it comes at a cost, with monthly subscriptions ranging from about $8 to $60, or the option for a lifetime membership for $4,000.
And that's not to mention the additional cost of any of Dr. Fuhrman's books, supplements or food products, which can further drive up the bill.
Here's a one-day Nutritarian meal plan to help you get started:
- Grilled Veggie Quinoa Salad
The Nutritarian Diet has pros and cons: On one hand, its emphasis on whole plant foods can help support heart health, stable blood sugar levels, weight loss and may even lower your risk for chronic disease.
And while the Nutritarian Diet doesn't have side effects per se, there are certain drawbacks. It limits some nutritious food groups, which can be restrictive and hard to maintain, and potentially lead to weight regain. What's more, certain elements of the program can get pricey.
Your best bet? Talk to your doctor about the right eating plan for you and your health needs. You can also explore other, less-restrictive eating styles that are backed by scientific research, like the Mediterranean diet.
