Eat Nuts to Prevent Weight Gain Over the Years

Remember…peanuts aren’t nuts, they’re legumes

Nuts are a staple of most paleo diets, including mine.

From NPR:

Eating a handful of almonds, walnuts, peanuts or any type of nut on a regular basis may help prevent excessive weight gain and even lower the risk of obesity, new research suggests.

It may be that substituting healthy nuts for unhealthy snacks is a simple strategy to ward off the gradual weight gain that often accompanies aging, according to the researchers. Nuts also help us feel full longer, which might offset cravings for junk food.Researchers looked at the diet and weight of more than 280,000 adults taking part in three long-term research studies. Over more than 20 years of monitoring, participants were asked every four years about their weight and, among other things, how often, over the preceding year, they had eaten a serving (about one ounce) of nuts.

A “New” Theory of Obesity From Kevin Hall

paleo diet, paleolithic diet, caveman diet

Not Kevin Hall

At Scientific American:

Nutrition researcher Kevin Hall strives to project a Zen-like state of equanimity. In his often contentious field, he says he is more bemused than frustrated by the tendency of other scientists to “cling to pet theories despite overwhelming evidence that they are mistaken.” Some of these experts, he tells me with a sly smile, “have a fascinating ability to rationalize away studies that don’t support their views.”

Among those views is the idea that particular nutrients such as fats, carbs or sugars are to blame for our alarming obesity pandemic. (Globally the prevalence of obesity nearly tripled between 1975 and 2016, according to the World Health Organization. The rise accompanies related health threats that include heart disease and diabetes.) But Hall, who works at the National Institute of Diabetes and Digestive and Kidney Diseases, where he runs the Integrative Physiology section, has run experiments that point fingers at a different culprit. His studies suggest that a dramatic shift in how we make the food we eat—pulling ingredients apart and then reconstituting them into things like frosted snack cakes and ready-to-eat meals from the supermarket freezer—bears the brunt of the blame. This “ultraprocessed” food, he and a growing number of other scientists think, disrupts gut-brain signals that normally tell us that we have had enough, and this failed signaling leads to overeating.

*  *  *

At the end of the 19th century, most Americans lived in rural areas, and nearly half made their living on farms, where fresh or only lightly processed food was the norm. Today most Americans live in cities and buy rather than grow their food, increasingly in ready-to-eat form. An estimated 58 percent of the calories we consume and nearly 90 percent of all added sugars come from industrial food formulations made up mostly or entirely of ingredients—whether nutrients, fiber or chemical additives—that are not found in a similar form and combination in nature. These are the ultraprocessed foods, and they range from junk food such as chips, sugary breakfast cereals, candy, soda and mass-manufactured pastries to what might seem like benign or even healthful products such as commercial breads, processed meats, flavored yogurts and energy bars.

Wasn’t David Kessler, M.D., saying the same things ten years ago?

Here’s another new theory from me: If you had to kill and butcher your own animals, you’d eat less.

Half of U.S. Adults Trying to Lose Weight

No wonder we’re so fat:

“Exercise, eating less, consuming more fruits and vegetables and drinking more water were the most common strategies. The least common were skipping meals and cutting down on fatty foods.”

Drinking more water? Come on, America, get serious. And it’s the rare person indeed who can lose with with exercise. You don’t have to cut down on fatty foods.

Which Foods Cause Obesity?

At my Advanced Mediterranean Diet website a few years ago I asked visitors to answer a poll question. 2,367 responded thusly:

What single food category makes you gain the most fat weight?

Fatty foods like bacon, butter, oils, nuts:
5%
Protein-rich foods: meat, eggs, fish:
0%
Sugary sweet items:
23%
Starches: bread, potatoes, peas, corn:
16%
Carbohydrates:
30%
Pastries, cake, pie, cookies:
25%
Other:
1%

Total Votes: 2367

Yes, I know it’s not a scientific poll, but it’s something. I’m not surprised at the results. I’m wishing I’d offered nuts as a choice since there are at least a few folks who gain weight on nuts, perhaps not realizing that nut calories are mostly from fat.

Why Are We in the U.S. Fat?

Your average Americans

There’s no shortage of speculation as to why 70% of us in the U.S. are overweight or obese. A few possibilities include:

  • we’re too sedentary
  • we eat too many carbohydrates
  • we eat too much fat
  • our foods are over-processed
  • we eat away from home too often
  • we eat too many industrial seed oils
  • our water and food are contaminated with persistent organic pollutants that disrupt our endocrine systems

I was reading an article at Nutrition Today and came across this graph of calorie consumption change from 1971 to 2004 (or 2000?):

A verbal summary is from this article cited by the the Nutrition Today authors: “During 1971—2000, a statistically significant increase in average energy intake occurred. For men, average energy intake increased from 2,450 kcals to 2,618 kcals, and for women, from 1,542 kcals to 1,877 kcals.”

So men’s daily calorie intake went up by 168, and women’s by 335.

The original article I read states, alternatively, that men’s daily caloric consumption rose from 2450 to 2693, a gain of 243. I can’t explain the discrepancy between 243 and 168, nor why 2004 is in the graph instead of 2000.

Maybe you don’t think an extra 168 calories a day is much. If you believe in the validity of the Energy Balance Equation, those 168 daily calories will turn into  17.5 pounds of fat in a year unless you “burn them off” somehow. If you weigh 150 lb (68 kg), you can burn those 168 calories by doing a daily 15-minute jog at 5.5 mph (8.9 km/hr). But you ain’t gonna do that. (I’m not getting into a debate about validity of the equation now; for another perspective, read Lyle McDonald.)

But year 2000 was a long time ago. How much are Americans eating now? According to a 2016 report from Pew Research Center:

Broadly speaking, we eat a lot more than we used to: The average American consumed 2,481 calories a day in 2010, about 23% more than in 1970. That’s more than most adults need to maintain their current weight, according to the Mayo Clinic’s calorie calculator. (A 40-year-old man of average height and weight who’s moderately active, for instance, needs 2,400 calories; a 40-year-old woman with corresponding characteristics needs 1,850 calories.)

Bottom line? We’re eating more than we did in 1970. Which could explain why we’re fat. Unless we’re burning more calories than we did in 1970, which I doubt.

PPS: Why we’re over-eating is a whole ‘nuther can o’ worms.

NASEM: Don’t Trust U.S. Dietary Guidelines

Back to the drawing board

NASEM is the National Academies of Sciences, Engineering, and Medicine. Dr. Andy Harris writes that:

The nation’s senior scientific body recently released a new report raising serious questions about the “scientific rigor” of the Dietary Guidelines for Americans. This report confirms what many in government have suspected for years and is the reason why Congress mandated this report in the first place: our nation’s top nutrition policy is not based on sound science.

Dr. Harris notes that since 1980, when the guidelines were first published, rates of obesity have doubled and diabetes has quadrupled.

Current recommendations to reduce saturated fat consumption and to eat health whole grains do not, after all, reduce rates of cardiovascular disease. That was my conclusion about saturated fat in 2009.

For a mere $68 you can read the NASEM report yourself. Better yet, read Tom Naughton’s thoughts for free.

Modern U.S. Women Weigh as Much as the Average Man of 1960

 

Way over 166 lb

Way over 166 lb

But women now are also about a half inch (2.2 cm) taller, so that explains it, right? Not by a long shot. The author of the article below blames unhealthy food, too much of it, plus physical inactivity. Since 1960, women’s average weight is up 18.5%, and men’s up 17.6%.

Click the link below for details. I quote:

The average American woman weighs 166.2 pounds, according to the Centers for Disease Control and Prevention. As reddit recently pointed out, that’s almost exactly as much as the average American man weighed in the early 1960s.

Men, you’re not looking too hot in this scenario either. Over the same time period you gained nearly 30 pounds, from 166.3 in the 60s to 195.5 today.

Excessive Loose Skin After Massive Weight Loss Is a Problem 

None of my patients has ever lost 650 lb (295 kg), but I’ve no doubt that skin that has been stretched out for decades doesn’t spring back into place.

NYT has an interesting article on it:

“It has been more than six years since Paul Mason, who once weighed 980 pounds and could not move from his bed, pulled himself back to life with gastric bypass surgery and his own strength of will. But he still carries his past with him.

On Wednesday, Mr. Mason, who is 55 and now lives in rural Athol, Mass., took another important step in a process that has been long and uneven, marked by small triumphs and unexpected setbacks. He had the second of two surgeries to eliminate the excess skin that enveloped his body like a shroud. Fifty pounds of it was removed from his abdomen last year; this time, about 10 pounds’ worth was excised from his arms and hip in a multihour operation in Manhattan.”
