Does Eating Meat, Poultry, and Fish Ruin Your Mood?

Cow's in a good mood. What a great place to live!

Your mood might improve if you restrict meat, poultry, and fish, according to a pilot study in Nutrition Journal.  I don’t have time to read it anytime soon.  Why don’t you, and comment below?

173 Years of US Sugar Consumption

US Sugar Consumption: 1822-2005

 Thanks to Dr. Stephan Guyenet and Jeremy Landen for this sugar consumption graph.  I’d never seen one going this far back in time. 
 
Dr. Guyenet writes:
It’s a remarkably straight line, increasing steadily from 6.3 pounds per person per year in 1822 to a maximum of 107.7 lb/person/year in 1999.  Wrap your brain around this: in 1822, we ate the amount of added sugar in one 12 ounce can of soda every five days, while today we eat that much sugar every seven hours.
The U.S. Department of Agriculture estimates that added sugars provide 17% of the total calories in the average American diet.  A typical carbonated soda contain the equivalent of 10 tsp (50 ml) of sugar.  The average U.S. adult eats 30 tsp  (150 ml) daily of added sweeteners and sugars.
 
Note that added sugars overwhelmingly supply only one nutrient: pure carbohdyrate without vitamins, minerals, protein, fat, antioxidants, etc.
 
Do you think sugar consumption has anything to do with diseases of affluence, also known as diseases of modern civilization?  I do.
 
Was our pancreas designed to handle this much sugar?  Apparently not, judging from skyrocketing rates of diabetes and prediabetes.

What Happened to Lard?

Lard? Wut choo talkin' 'bout, Willis?

Lard may be making a come-back.  An NPR article reviews its fall from grace, with mention of Upton Sinclair, Procter and Gamble, and Crisco.

Book Review: Choose to Lose: The 7-Day Carb Cycle Solution

I saw the author of Choose to Lose on a rerun of Dr. Oz in early January.  Then I checked the book’s sales rank at Amazon.com (22nd overall—a blockbuster in my view).  (Don’t get me wrong; I’m not in the habit of watching Dr. Oz.)  Here’s my review of 2012’s Choose to Lose: The 7-Day Carb Cycle Solution, by Chris Powell.  The book is for the general public, not people with diabetes.  I give it three stars per Amazon.com’s five-star system.

♦   ♦   ♦

Will it work?  Certainly for some, quite possibly a majority.  Like most published programs, it’ll work for for you if you work the program.  Question is, can you do it?

The underlying idea is to alternate high-carb and low-carb eating days, which supposedly revs up your metabolism and tricks your body into thinking it’s not on a diet so it won’t go into self-preservation starvation mode.  Mr. Powell calls this carb cycling.

The high-carb days are also low-fat, and the low-carb days are low-calorie.  Actually, both days are reduced-calorie if your goal is the most dramatic results.  A moderate calorie deficit is built into the program.  Women get about 1350 calories; men around 1700.  Those levels are lower than necessary. Other than that, it appears you’ll get all the other nutrients you need, which is good.

I can see how the diet would work for some because it drastically reduces consumption of our most fattening carboydrates.  Loser Choosers aren’t supposed to eat baked goods, white flour, refined sugar, beer, candy, chips (crisps, for those in the UK), conventional breads, cookies, crackers, ice cream, sugar-sweetened beverages, corn syrup, and milk.  I suspect if we all stopped eating those right now, the overweight rate in the U.S. would drop by at least 10% in the next 12 months.

The author allows no wheat or white rice except for whole wheat bread and pasta.  Potatoes, peas, and corn made it to the “approved” list.  You eat mostly natural, minimally processed foods (yay!).

I don’t know Mr. Powell, but he comes off as earnest, honest, compassionate, experienced, and intelligent.  He’s not a scammer.  Mr. Powell has more faith than I do in the benefits of exercise for weight loss.  He notes that nutrition is more important.  We agree that exercise is often critical for prevention of weight regain.  He barely, if at all, mentions the benefits of exercise in prevention of disease and prolongation of longevity.  His well-illustrated exercise recommendations are  a good start for fitness beginners.  He wants you to exercise for 10-30 minutes on six days a week, doing a combo of cardio intervals and body weight resistance training.  No expensive equipment to buy.

Carb cycling like this is supposed to “boost your metabolism to burn fat quickly.”  It does not, to any clinically meaningful extent.  Nor is carb cycling mentioned in this year’s massively referenced The Smart Science of Slim.  Contrary to the author’s opinion, neither eating five meals a day nor eating carboydrates revs up your metabolism.

Mr. Powell provides some helpful mind tricks to prepare you for a lifestyle change.

My favorite sentence: “Success doesn’t just happen.  It’s a result of the 4 Ps of action: Planning, Preparation, Performance, Persevance.”

My least favorite sentence: “Water is imperative for loosing [sic] weight.”  A close second was: “Alcohol is a powerful diuretic (it flushes water out of your system), so it dehydrates you, causing water retention and bloating for one to three days after you drink.”  Huh?

I like his incorporation of cheat meals, although he allows more than I would.  To his credit, the all-important maintenance phase is covered well.

Mr. Powell recommends supplementing with probiotics and digestive enzymes, being unaware of their uselessness for most dieters.

I note that Amazon sells Choose to Lose by Dr. Ron and Nancy Goor, and The Carb Cycling Diet by Dr. Roman Malkov.  Coincidence ? 

In terms of complexity, the program is about average. 

I wonder if you’d do just as well by swearing off the fattening carbohydrates I listed above.  If you’re looking to lose weight, you could do a lot worse than Choose to Lose.  And you could do better.

FDA Approves Exenatide for Once Weekly Use

Once-weekly injection of exenatide, sold in the U.S. as Bydureon, has been approved for use by the U.S. Food and Drug Administration.  It’s main competitors are Byetta (exenatide  injected twice daily) and Victoza  (liraglutide).  Byetta  and Bydureon are made by the same company, Amylin Pharmaceuticals.  Bydureon apparently is a slow-release formulation of exenatide.

Victoza is the one that celebrity chef Paula Deen endorsed about a month ago, around the same time she revealed she’s had type 2 diabetes for three years.  Victoza’s injected once daily.

The New York Times has a January 27, 2012, article on Bydureon, focusing on business and investing.  The new drug is expected to retail for $4,200 (USD) a year. 

Click for complete prescribing information.

David Mendosa is excited about Bydureon.

These drugs are in a class called GLP-1 receptor agonists, which mimic the effect of glucagonlike peptide- 1, a hormone that increases insulin secretion by the pancreas when blood sugar levels are high.  They are prescribed as adjuncts to diet and exercise in adults with type 2 diabetes.

What About Sugar Alcohols?

Dietitian Brenna at Eating Simple recently posted an article on artificial sweeteners exclusive of sugar alcohols.  Now she’s reviewed sugar alcohols.  Many who have a sweet tooth, including myself, use sugar substitutes such as sugar alcohols.  Sometimes they affect blood sugar levels, although not as much as sugar.

Dr. Maria Collazo-Clavell at the Mayo Clinic wrote about use of artificial sweeteners by people with diabetes.  Like Brenna, she notes that sugar alcohols can raise blood sugar levels in people with diabetes.  The Mayo Clinic has another article on sugar substitutes.

UCSF Investigating Paleolithic Diet For Diabetics

  A May, 2010, press release from University of California San Francisco outlines the university’s research into use of the Paleolithic diet (aka Stone Age or caveman diet) for people with type 2 diabetes.  From the press release:

The initial research findings are striking. Without losing weight, participants in a preliminary study improved blood sugar control, blood pressure control and blood vessel elasticity. They lowered levels of blood fats such as cholesterol. And most amazingly, participants achieved these results in less than three weeks — simply by switching to a Paleolithic diet.

The lead researchers are nephrologist Lynda Frassetto and endocrinologist Umesh Masharani.  Frassetto and team had previously looked at metabolic improvements linked to the paleo diet.

We await publication of their current findings in a peer-reviewed scientific journal.  C’mon people, it’s 2012 already.  In the meantime, I prefer the Low-Carb Mediterranean Diet.

Brenna Reviews Sugar Substitutes

Too late now!

Dietitian Brenna at Eating Simple has a recent post on sugar substitutes, which I sometimes refer to as non-caloric sweeteners (not entirely accurate).  She reviewed sucralose, saccharine, aspartame, and acesulfame potassium.  Not sure why she didn’t cover sugar alcohols like xylitol, erythritol, and sorbitol.  Brenna links to a Mayo Clinic article on artificial sweeteners, including sugar alcohols.

I never got excited enough to cover this topic in detail myself.  Thanks, Brenna.

Steve Parker, M.D.
