The One Superfood Worth Eating Every Day to Boost Metabolism, Top Nutritionist Reveals

Do you want to eat your way to weight loss? According to Dr. Steven Gundry, MD, medical director at The International Heart and Lung Institute Center for Restorative Medicine and the New York Times best-seller The Plant Paradox and The Plant Paradox Cookbook, losing weight isn’t just about eating less, but about eating the right kind of superfoods. In one of his viral YouTube videos, he reveals the “top three foods for weight loss.”

Dr. Gundry Struggled to Love 70 Pounds, But These 3 Foods Helped

“Still struggling to lose weight, I get it. I was 70 pounds overweight for years, and no amount of exercise or healthy eating helped until I discovered that weight loss comes down to what you eat and what you don't eat,” Dr. Gundry reveals. “So today I'm sharing my top three foods you should be eating to help you shed the pounds and live your happiest, healthiest life.”

1. Prebiotic Rich Foods

“Number one, and I can't say this enough: Prebiotic rich foods,” Gundry reveals. “Now there's always some confusion about a probiotic, a prebiotic, and now a post-biotic.”

Probiotics Eat Prebiotics

“So real quick, probiotics are friendly bacteria, and probiotics have to eat something, and the foods that they have to eat are called prebiotics,” he says.

Polyphenols Are Great Prebiotics

“Now, most of us associate prebiotics with fiber, but a lot of prebiotics really aren't fibers. For instance, in my new book, unlocking the Keto Code, I introduced you to the fact that polyphenols, which are plant compounds that give plants their color, are actually prebiotics for the bacteria in our gut. And with each passing year, evidence is accumulating that these polyphenols may, in fact, be the most important part of prebiotics that we've neglected over fiber per se,” he says.

Gut Bacteria Then Makes Postbiotics

“Now, don't get me wrong, fiber that is edible by our gut bacteria is equally important because gut bacteria use fiber, use prebiotic fiber, and use prebiotics to make chemicals called postbiotics. And this is where it gets really confusing. Postbiotics simplistically are the byproducts of bacteria, probiotics, eating prebiotics, and these postbiotics are signaling compounds,” he continues.

A Calorie In Does Not Equal a Calorie Out, He Says

“Signaling compounds tell our mitochondria what to do, tell our genes what to do, tell our cells what to do. The exciting thing about these signaling molecules in terms of weight loss is they actually promote weight loss by having your mitochondria literally waste calories to do a caloric bypass on the food you eat. And that's actually exciting news because it means that a calorie in equals a calorie out is not true,” he says.

Prebiotics Will Help You Lose Weight

“Many of the calories that you eat, which are prebiotics, whether they're fiber, whether they're polyphenols, will actually make you lose weight more than the amount of food that you are eating, which is really, really exciting,” he says.

He Says to Use More Spices

“The more fiber-rich foods you get in your diet, the more polyphenols you get in your diet by eating brightly dark colored vegetables by using spices. Spices are dense in polyphenols, and so anytime you can add fiber and polyphenols, you are going to have a weight loss benefit. You can use spices in everything,” he says.

Make Smoothies

“One of the easy ways to get these compounds into your diet is to make a smoothie. It's really easy to get fiber in smoothies, and it's tasty. Now, there are a lot of fiber supplements out there, but beware, a number of fiber supplements like Metamucil, for instance, are loaded with sugar or if they're low calorie or no sugar added, they use sucralose, which is Splenda or any of the other artificial sweeteners, which believe it or not, kill off your friendly bacteria,” he says.

Or Get Inulin Powder

“It's much easier to add fiber to your diet. One of the easiest fibers to add to your diet is inulin. And inulin is present as a powder. It has a slightly sweet taste. You can put it in your smoothies, or you can add it to your vegetables. There are inulin-rich vegetables, asparagus, Jerusalem artichokes, sometimes called sunchokes, and the chicory family, like radicchio and Belgian endive,” he says. “So the more of these sorts of vegetables you get in your diet, the easier it is to do this.”

2. Avocados

The second best food to add to your diet is avocados. “I can't say this enough. Do not be afraid of fat. Contrary to popular belief, eating an avocado a day does not make you fat. In fact, avocados do exactly the opposite,” Dr. Gundry says.

Avocados Help You Absorb Nutrients in Food

“Avocados help you absorb the nutrients in food. In fact, there's a very famous study of having people eat salads with and without avocado, and it was found that the addition of the avocado made people absorb the nutrients, vitamins, and minerals in that salad much better than if the avocado wasn't there in the first place,” he says.

They Are Also a Great Source of Monounsaturated Fat

“Avocados have great monounsaturated fat. It's called oleic acid. It's the same fat in olive oil. And avocados are rich in prebiotic fiber. And so these compounds actually help you lose weight,” he says.

Eat One a Day

How many should you eat a day? “Well, there is a human study that shows the addition of one avocado a day actually improved weight loss over not having the avocado a day. So what the heck? Have an avocado a day, have some guacamole,” he says.

His go-to recipe? “Half an avocado. Take the pit out, put an egg yolk in each hole, and put it in the broiler. It's a phenomenal breakfast. It's a phenomenal snack,” he explains.

Or, Another Source of Fiber

“What can you substitute if you're sensitive to avocado? Well, we have a few people who do react to avocados. It's unusual, but it does happen. In that case, don't have an avocado. Instead, use other sources of fiber rather than an avocado,” he says.

3. MCT Rich Foods

“The number three thing that you should add to your diet to help you lose weight is MCT-rich foods,” he says. “Now, most people have heard of MCT oil, medium chain triglycerides. It's becoming easy to find Costco, even as MCT oil.”

Coconut Oil Does Not Have the Same Benefits

“Coconut oil does not have the same benefits as MCT oil,” he says. “Studies that I talk about in unlocking the Keto code Show that people who are asked to have MCT oil as part of their diet versus people who did not have MCT oil as part of their diet lost three to five kilograms of weight in six weeks just by adding MCT oil to their diet. And we're not talking about a lot. Probably three tablespoons a day will do it for most people.”

Goat and Sheep Products Also Have MCT Oil

“Now, the other great news is that MCT oil is present in goat and sheep products. So goat yogurt, sheep yogurt, goat kefir, sheep kefir, goat cheese, sheep cheese. 30% of the fats in these products are medium chain triglycerides,” he says.

If You Eat the Right Fats and Avoid Refined Carbs, You Will Lose Weight

The bottom line? “If you eat the right kinds of fat and if you eat them during the right times and you don't eat fats with refined carbohydrates, fats can actually help you lose weight,” he reveals. And if you enjoyed this article, take advantage of these 20 Superfoods for People Over 50.
