Given up on losing weight?

The number of overweight and obese Americans has climbed steadily in recent decades, from 53% of adults in 1988 to 65% in 2014. At the same time, fewer overweight Americans are trying to lose weight--just 47%, down from 55% back in 1988.

The authors of the study, which was published in JAMA this month, wondered whether we've simply made our peace with being fat.

"As more people around us are getting heavier, we simply believe we are fine, and no need to do anything with it," lead author Liang Zhang told the AP News Service.

That may be part of it.

What’s the optimal timing for meals and exercise?

Every week, there seems to be a new study or analysis on these questions, such as the one I reviewed in last week’s Nutrition Diva podcast, and others that I’ve tackled in countless other posts and podcasts over the years.

Having spent so much time reviewing all this evidence, I thought I’d share with you my typical eating/exercise schedule. Continue reading “What’s the optimal timing for meals and exercise?” >

Should our toddlers really be eating this much fake sugar?

Would you let your two year old drink diet soda?

Would you let your 7-year-old drink diet soda?

How about your 2 year-old?

A disturbing new study finds that 27% of elementary-school kids and 20% of our preschoolers are consuming artificial sweeteners on a daily or near daily basis.  This represents a 300% increase since 1999.

[bctt tweet=”20% of preschoolers consume artificial sweeteners on a daily basis.”]

With all the scary news about sugar these days, many parents may imagine that they’re doing their kids a favor by offering them sugar-free pudding or low-calorie fruit “juice.”  And the fact that artificially sweetened foods are “sugar-free” might make them seem safe for every day consumption. I suspect they are anything but. Continue reading “Should our toddlers really be eating this much fake sugar?” >

NYT protein piece generates more heat than light

imagesThere’s been a lot of buzz this week about a column in the New York Times on the potential consequences of eating “too much” protein.

Well columnist Roni Rabin worries that the popularity of protein powders, drinks, and bars are “making it possible to effortlessly consume protein in amounts that far exceed dietary recommendations.”

She goes on to write that “the vast majority of Americans already get more than the recommended daily amounts of protein.”

But are they really? The Institutes of Medicine–a relatively conservative bunch–recommends that we get between 10 and 35% of our calories from protein. For a 150 pound adult, that translates into a range of 55 to 180 grams of protein per day. Continue reading “NYT protein piece generates more heat than light” >

This year, give thanks by reducing food waste

thanksgiving-1801986_640

Those of us in the U.S. are celebrating Thanksgiving tomorrow and I just read a disturbing statistic: Of the 700 million pounds of turkey that will be purchased for tomorrow’s holiday feasts, about 235 million pounds will end up in the trash.

Food waste is a problem year round, of course. But on a day when we gather to give thanks for abundance, let’s honor the harvest  by pledging to reduce the amount of food that goes into the trash this weekend.

The food advocacy group Foodtank has compiled an excellent list of tips for a food waste-free Thanksgiving. Tops on my list will be making sure that leftovers are put away promptly. Anything that won’t be eaten within a few days will go into the freezer for future use.

Using smaller plates and letting guests serve themselves not only reduces the amount of food that gets scraped off plates and into the trash but it may actually help you from over-eating. (Here are some other tips on how to avoid overeating on Thanksgiving.)

What are your plans for reducing food waste this holiday season?

Calcium Supplements: Safe or Not?

heart-care-1040250_960_720

The National Osteoporosis Foundation published a new report this week, insisting that calcium supplements are safe for your heart. Two weeks ago, Johns Hopkins cardiologist Erin Michos published a paper saying the opposite.

She notes that the NOF review (which was funded by a pharmaceutical company that makes calcium supplements) omitted certain studies (such as the ones she included in her own review) that might have changed the conclusion.

These are just the latest two volleys in a five-year-long tennis match between experts on whether you should or shouldn’t take calcium supplements.  And you thought politics was divisive.  Continue reading “Calcium Supplements: Safe or Not?” >

How to Slow Age-Related Muscle Loss

By the time we’re in our 30s, most of us have already reached our peak in terms of lean muscle mass. From that point on, most of us are gradually losing muscle. It’s not obvious at first, but by the time you’re in your 60s or 70s, the difference in body composition is really dramatic. At that age, you usually see a lot less firm muscle tone and a lot more soft flesh and loose skin.

But age-related muscle loss isn’t just a cosmetic issue. So much of the loss of function and vitality that commonly accompanies aging actually begins with this gradual loss of muscle tissue starting in mid-life. As we lose muscle, we lose strength and stamina and this means we can’t do as much as we used to. We aren’t as strong and we tire more easily.

As you lose muscle, you also tend to lose bone tissue. Thinning bones eventually lead to the frailty, falls, and fractures that we typically associate with people in their 80s—but the seeds for this are sown way back in middle life when we start losing muscle mass.

OK enough with the bad news. How about some good news? If you can hang on to more muscle as you age, you can turn this entire ship around and age more successfully. And I have some strategies that can help you do just that.

How to Slow Age-Related Muscle Loss

I recently got an email from David, who wrote: “I’m a 54-year-old man with an excellent diet, plenty of exercise, and no medical issues. Like many men my age, I’m experiencing gradual muscle loss. I supplement with protein powder, and I’m wondering what other things I might take that might help with muscle loss, or any other tips you might have.”

Of course, there are no shortage of supplements that claim to help you build muscle. But these supplements have a dubious record of safety and efficacy. So, David, before you start taking any other supplements, let’s be sure that you’re getting the maximum benefit out of the nutrients that you’re already taking in—including your protein powder.

Timing Your Protein Intake

As you may have suspected, dietary protein is key to building and maintaining muscle mass. But it’s not necessarily a matter of taking in more protein. The typical 50-year-old guy gets about 90 grams of protein, which enough to maximize muscle protein synthesis. However, he may be eating the lion’s share of that protein at dinner time. In the US, we get about 42% of our daily protein at dinner and only 16% at breakfast.

In terms of maximizing muscle synthesis, this is a missed opportunity.

Research shows that for guys in their twenties, muscle synthesis peaks at an intake of about 20 grams of protein. As we get older it takes a little more protein to hit that peak—about 30 grams at a single meal. That’s about what you’d get from four ounces of cooked chicken, lean beef, pork, or about six ounces of tofu. Protein intakes above that amount don’t really provide any extra muscle-building benefit.

Now, consider our typical eating patterns: If we’re only eating 10 or 15 grams of protein at breakfast, we’re not consuming enough maximize muscle protein synthesis. Meanwhile, if we’re eating 50 grams of protein at dinner time, some of that protein is being wasted in terms of its muscle-building benefits.

You can build and maintain more muscle by dividing up your protein intake more evenly over the day.

So, even without increasing your total protein intake at all, you can build and maintain more muscle by dividing up your protein intake more evenly over the day. Instead of hitting that muscle-building peak dose of protein only once a day, you could be reaching it three times a day. In terms of hanging on to muscle mass as we age, this could make a big difference.

How to Increase Protein at Breakfast

Protein powder can be an easy way to increase the protein content of breakfast without adding an excessive number of calories or having to eat a huge meal. For example, you can add a scoop of whey protein to a smoothie, stir it into your oatmeal or yogurt, or even blend it into your peanut or almond butter and spread it on toast.  If you’re a breakfast baker, you can replace 1/3 of the flour in your muffin or pancake recipe with whey protein powder. Any one of these strategies can boost the protein in your breakfast from the typical 10-15 grams to the optimal 30 grams.

Try to include a similar amount of protein at lunch and dinner, too. (You can look up the amount of protein in common foods using a diet tracker like My Fitness Pal) or on my Protein Cheat Sheet.

Unintended consequences of the clean eating movement

Is this chemical in your food?
Is this chemical in your food?

Eating “clean” has been a buzzword for a couple of years now, even though the term is so vague that it’s hard to know whether you’re doing it or not.

There is no concrete definition for “clean” food but for most people it suggests eating foods that are closer to their natural state and less processed. Although it’s pretty easy to identify a green bean as “clean” and a jelly bean as not, foods like cheese or bread or orange juice occupy a gray area somewhere in between.

“Don’t eat anything you can’t pronounce” is another common refrain, and this has led food manufacturers to “clean up” their labels by removing preservatives and other additives. But our mistrust of multi-syllabic words is having an unintended consequenceContinue reading “Unintended consequences of the clean eating movement” >
