2020: What are the Best Diets?

Well, the results are in, and you may not like what they have to say about your favorite diet.

U.S. News & World Report loves to provide “Best” rankings for a slew of categories, such as doctors in every specialty and colleges. Now their panel of experts has weighed in (no pun intended) on what they have whittled down to the top 35 diets overall. You might be surprised to learn where your particular diet lands on their favorite list. I’ll cover the top 5 only, and then tell you how the popular Keto ranks and why, but you can go to the link at the bottom of this post to see all 35 diets.

How the top 5 diets rank and why?

Okay, here’s number 1.

Drum roll, please. Brrrrrrrr….

 

  1. Mediterranean Diet

No real surprise here. This diet has been studied and emulated for years. But which country bordering the Mediterranean are they following the recipes and food of? They all tend to eat slightly different foods.

I think by now most people know that people that live in this part of the world consume good oils—like olive oil and good fats that primarily come from fish, but other key take-aways to any Mediterranean diet are that these people:

  • Have active lifestyles
  • Eat in a way that helps control weight
  • Consume low amounts of meat, sugar and saturated fat
  • Eat a lot of produce, nuts and other healthful foods
  • Eat primarily organically-grown fruits and veggies (that come from smaller or personal farms)

If you’d like more information on what foods to eat in what amounts, see the consumer-friendly Mediterranean diet pyramid developed by experts in a Boston food think tank.

(Who knew there was such a group!)

This diet was also awarded kudos for being nutritionally sound and having diverse foods and flavors.

 

  1. DASH Diet

Okay, I must admit I’d never heard about this diet, which stands for Dietary Approaches to Stop Hypertension. But evidently it’s known for fighting high blood pressure and its nutritional completeness, safety, ability to prevent or control diabetes, and its role in supporting heart health.

It emphasizes:

  • fruits
  • veggies
  • whole grains
  • lean protein
  • low-fat dairy

It turns its thumbs down on:

  • fatty meats
  • full-fat dairy foods
  • tropical oils
  • sugar-sweetened beverages and sweets

Under the pro category, this diet was noted for being heart healthy and nutritionally sound.

 

  1. The Flexitarian Diet

Here’s another one I’d never heard of, which came about in 2009 when dietitian Dawn Jackson Blatner published her book The Flexitarian Diet: The Mostly Vegetarian Way to Lose Weight, Be Healthier, Prevent Disease and Add Year sot Your Life.

This diet—which is the marriage of flexible and vegetarian—emphasizes fruits, veggies, whole grains and plant-based protein. But Ms. Blatner says you can be a vegetarian most of the time but still enjoy an occasional fatty burger or steak when the urge strikes.

It was noted for its flexibility and abundance of tasty recipes.

 

  1. WW (Weight Watchers) Diet

Weight Watchers has done a good job evolving with the times and bringing their diet up to the modern research. It scored highest for overall weight loss and fast weight loss. But WW is also focusing on healthy living and overall well-being.

A big plus to the WW diet is the support system, via in-person accountability and support workshops and on-line or phone chats. The support people are trained in behavior weight management techniques.

With no foods being listed as off-limits, this diet scored big for being able to eat what you want, and for the flexibility in shaping your own diet.

 

  1. Mayo Clinic Diet

I did this diet as a high school junior. Way back then, it focused on very high protein meals, with eggs and meat being the centerpieces. I lost a heap of weight in two weeks, in time to be a bit more svelte for the National Gymnastics Championship.

Now it focuses on making healthful eating a lifelong habit. It also earned high marks for its nutrition and safety.

Mayo’s diet is focused on helping you get your eating habits straightened out and breaking bad habits and replacing them with good ones. They also have their own unique food pyramid, which emphasizes fruits, veggies, and whole grains, which allows you to eat more while taking in fewer calories.

According to Mayo, someone on the diet can expect to lose 6 to 10 pounds the first two weeks (!), a lot of which I would expect to be water, and then 1 to 2 pounds weekly until you’ve hit your goal weight. I’m not sure what you do when you hit it, but that is probably in the book.

The 6 to 10 pounds seems like a lot to me. I’ve read a lot of information cautioning people against losing that much weigh that rapidly—for heart reasons, and also for the inclination your body has to reset your calorie point to a lower per-day need before kicking into starvation and fat-storing mode with such drastic weight loss.

But they’re Mayo, and they’ve undoubtedly done their research and checked it twice.

It got additional marks for being nutritionally sound and allowing you to shape your diet.

 

  1. MIND Diet (Tied with Mayo and Volumetrics below)

The Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) is another new one to me, but it’s definitely keeping up with the current concerns on maintaining mental health, as it aims to prevent mental deterioration.

One expert found it to be a healthy, sensible plan backed up by science. (I always love how they throw that in, and then we learn a decade later that “new” science has deleted the old facts.)

What this diet does is take both the DASH and the Mediterranean diets and focus on the foods in each one that specifically affect brain health.

I’m always a little concerned when diets focus too much on one aspect of health, but evidently this diet has been found to reduce Alzheimer’s risk by 35% for people who followed it moderately well and 53% for people who really adhered to it. So I think it deserves a closer look.

It does focus on fewer carbs than is currently recommended by our government guidelines and is known to bring on quick weight loss.

The pro category had marks for its blending of two proven healthy diets and its brain-power boosting focus. The cons were that the diet details were not “fleshed out” and the recipes and resources were slim.

 

  1. Volumetrics (Tied with Mayo and MIND, above)

Penn State University professor Barbara Rolls pioneered this diet, which experts say is really more of an eating approach than a focused diet. It’s designed around:

  • learning how to decipher a food’s energy density
  • learning how to cut that energy density in meal planning and eating
  • making choices that fight hunger

Food is divided into four groups: very low-density, low-density, medium-density, and high-density. You might already guess that non-starchy fruits and veggies would fall into the very-low density category, while crackers, chips, chocolate candies, cookies, nuts, butter and oil fall into the very-high level.

The pro checkmarks for this diet were that it is filling and no food is off-limits. The negatives included lengthy meal prep, and if you don’t like fruits, veggies or soups, sticking with it could be tough.

 

The list continues with a total of 35 rankings, including Jenny Craig, Nutrisystem, Dr. Weil’s Anti-inflammatory Diet, Dr. Dean Ornish’s Diet, Vegetarian, Vegan The Engine 2 and Paleo.

 

But where did the Keto diet fall?

In spite of its increasing popularity and the medical attention it’s receiving, experts rated this popular diet near the bottom, at #34, behind Paleo (at 29), and Atkins (32). And even though more research is being done on the effects of this diet, a July 2019 Journal of the American Medical Association Internal Medicine (JAMA Internal Medicine) stated that “enthusiasm outpaces evidence” when it comes to a keto diet having a dramatic effect on diabetes or obesity.

A friend of mine from high school is a keto-type diet aficionado and it has helped her tremendously with her diabetes control and weight maintenance. She said it was such a relief to no longer have to count carbs for her daily glycemic intake measurements. The last time I saw her, she looked healthy and had a ton of energy.

Granted, that’s anecdotal evidence, but it’s important to her and her health. Since it takes a long time to do research, it may be that the evidence is just taking time to catch up.

 

To see the entire list, read the overviews, and get more information on each of these diets, see the report.

 

And until next week, (when I’ll tell you about the new diet geared toward people suffering from acid reflux that my husband and I have embarked on),

Happy Dieting!

Is Exercising More or Reducing Calories the Answer to Successful Weight Management? What You Need to Know About the Science of Weight Loss

Which of these statements have you heard?

“To lose weight, all you need to do is eat less and exercise more!”

“Losing weight is all about calories in and calories out.”

“All calories are the same—a calorie is a calorie is a calorie.”

 

For years this is what we were taught in nutrition and exercise physiology classes, and it’s what we told our patients.

Recent research is showing that these statements don’t paint the whole, complex weight loss picture. But before we dig deeper into what we’re learning now, let’s get an overview of the ugly reality of weight and fatness in the United States.

 

The discouraging facts—

  • In 1990, 15% of adults were classified as obese.
  • Now, at least 71% of Americans are considered to be overweight; nearly 40% are clinically obese.
  • Sadder still is that 17% of kids and teens are obese. When I was a kid it was rare to have a fat kid in your class. (I know that blunt statement sounds mean, but we need to start calling it like it is: these kids are in serious danger of having premature health problems and living burdened lives saddled with chronic health issues.)
  • Excess body fat dramatically increases the risk of serious health problems, like:
  1. Type II Diabetes
  2. Heart Disease
  3. Depression
  4. Respiratory problems
  5. Major cancers
  6. Fertility problems
  • Millions and millions and millions of us spend billions on diet pills, special meal plans and group weight loss programs, and gym memberships.
  • The National Institute of Health considers the problem to be so dire that the organization provided 931 million dollars in 2018 to research the problem.

 

What does the recent research show?

So what has all of that money and research shown us? The answer is both complex, and a relief.

Scientists have concluded that a calorie is not always a calorie, and that it’s not as easy as calories in and calories out.

What they have found is: it’s the composition of the food you eat rather than how much of it you can burn off exercising that allows you to sustain, and maintain, weight loss.

And these scientists know something else: the diet that’s best for your friend is probably NOT the best one for you!

Evidently people’s individual responses to diets vary enormously. But what they’re not absolutely sure about is why that’s true.

 

So what’s a dieter to do?

Apply yourself to finding out what works for you! And that may require some trial-and-error time.

 

A story of the dreaded calorie and counting it—

Before WWI, scientists throughout Europe had been focusing on and studying the concept of a calorie being a unit of energy. In college, that concept was hammered into my head, and into my nutrition calculations. We studied bomb calorimeters— wonderful devices you put food into and burned so you could determine just how much energy was released during the destruction process. That gave you the calorie count for that particular food item.

But in WWI, in the midst of a global food shortage, the United States wanted a way to prompt people to reduce their food intake. So the government devised its first-ever “scientific diet” for Americans to follow. At its core was the concept and practice of counting calories.

The following decades saw bone-thin bodies as the ideal body structure, so dieting plans were developed along the idea of eating low-calorie meals. One example of this is the still–popular grapefruit diet, where you consume half a grapefruit at every meal. People believed the grapefruit enzymes were natural fat burners. Then the cabbage-soup-every-day diet appeared. I’m not sure what they thought the cabbage might contribute, except to enhance digestion and whisk the fat away.

Then in the 1960s, a woman named Jean Nidetch and her co-founders became insta-millionaires with their Weight Watchers meetings program. She turned a small, weekly encouragement meeting she held in her living room into a billion dollar (today) business.

Her idea promoted that if you ate less fattening food, then the weight would disappear. That helped propel the late 70s idea that if you just eat less fat, you’ll be less fat. I remember promoting that erroneous idea in the 80s. Based on what I’d learned in school, it seemed to make sense—fat gets stored in the body as fat, so if you consume less of it, then you should wear less of it.

How did that work out?

Not well. Not only did people not lose weight, they actually gained weight!

 

The metabolism factor—

Something else scientists have found contributes to what’s been a frustrating mystery.

When you lose weight, your resting metabolism (the energy your body burns while at rest, just to keep the system going) actually slows down. And when you gain back some of the weight, that metabolism doesn’t speed up. It remains stubbornly entrenched in slow mode. And the number of calories a day it doesn’t burn can be startlingly high.

For some contestants on the reality show The Biggest Loser, their metabolisms registered at burning around 700 fewer calories per day than they did prior to their fat burning journey on the show!

But my question is: could that result be due to the fact that contestants lost a huge amount of weight in a very short period of time, something doctors do not encourage, for a variety of reasons, including heart health.

 

Regardless of the answer, the sad truth is that most people replenish their lost weight at two to four pounds per year.

On the surface, this finding seems to support the idea that the body undermines your efforts to take away what it wants to keep.

 

More of the weight loss story—

Some people—and you probably know one—seem to succeed in losing weight with any diet approach.

Yet there is a bright side to the story.

Take a group of people eating a low-carb diet and compare them to a group following a low-fat plan, and you see almost no overall difference in the weight loss results.

What you do see, however, are three types of people: those who lose a lot of weight on the plan they’re following; those that stay stagnant, with no weight loss; and those that actually gain weight.

Do scientists understand why that happens? Unfortunately, not yet, but they are making inroads to cracking the secret.

 

Rena Wong, a Brown University professor of psychiatry and human behavior has been tracking dieters for 23 years through the National Weight Loss Control Registry (NWCR). What she and her colleagues have found is that most of the people on the list have lost significant amounts of weight—a minimum of 30 pounds—and been able to keep it off for several years by varying means.

The significant finding? Most of these people had to try more than one diet before landing one that worked for them.

 

How did these dieters keep their lost weight off?

It turns out that the most successful dieters have some similar characteristics:

  • Most modified their diet in some way.
  • Most reduced how much food they ate in a day.
  • 94% increased their physical activity.
  • The most popular exercise among them was walking.
  • Most ate breakfast on a daily basis.
  • Most weigh themselves weekly, in order to keep an eye on weight creep.
  • Most watch less than 10 hours of television weekly.
  • Most exercise a minimum of an hour every day.

 

And they also have similar attitudes and behaviors:

  • Most do not consider themselves to be hard-charging, super-performer Type A’s.
  • Most are self-described morning people.
  • Most were motivated by a health scare; a desire to live a longer, healthier life; and to be able to spend more time with their loved ones.
  • And they were highly motivated to find what worked for them and to persevere.

 

Take-home lessons for us:

This information can be disheartening and encouraging.

It tells us that we can lose weight, if we diligently try to find the method that works for us, stay determined and positive, and persevere in best diet practices for our body, at any age.

It’s nice to know that there’s more to the story. It gives many of us a sense of relief and re-invigoration of determination and hope.

And I think it’s important for us to always remember that a loving God fearfully and wonderfully makes all of us. He starts knitting us together in our mother’s womb.

 

I know only too well how easy it is to throw up your hands in frustration when the one-size-fits-all plan fails you. But I invite you to rejoice over your uniqueness, knowing that you will find something that gives you success, if you want it badly enough and are willing to stick with it.


NEXT WEEK: How to find what diet and exercise regimen works for you.

Until then, take heart, you can find success if you know the science of weight loss!

Blessings,

Andrea
