The Dark-Chocolate Study: The Problems

/in /by

After Thursday’s memo, you’ve got to be wondering what could be worse with the dark-chocolate study than its misleading conclusions. I’m going to examine the process the author explained in his faux study to show how that applies to many research studies from legitimate health research.

Not enough of the right expertise
There was no input from a nutrition expert that I could find. The author used a physician to do the study and collect the data. Even though the purpose of the study was to prove that eventually something will be statistically significant . . .

Problems with the Dark-Chocolate Study

/in /by

The journalist and his colleagues who perpetrated the dark chocolate and weight loss study I talked about Tuesday were out to prove a point: typical journalists, even the ones who specialize in health, don’t really understand the fundamentals of nutrition, weight loss, and fitness. They especially don’t understand statistics and how they’re misapplied even in legitimate studies. Nothing new there.

What I think they did show was that there are many news and information sources on the web that will publish anything provocative. Dark chocolate helping weight loss certainly fit that profile.

The author explained everything he . . .

Dark Chocolate and Weight Loss

/in /by

Late last week, Paula and a couple of readers sent me links about a journalist who managed to get a study on dark chocolate and weight loss published in a scientific journal in March 2015 (1). It made headlines everywhere. Then in late May, he wrote about how he fooled the journalistic world (2). While a lot has been written about his sting and the reasons he said he did it, there are more issues here than have been written about so far, and that’s what I’ll talk about this week. Let’s begin with the study.

The Real Agenda: Refined Carbohydrates

/in /by

Let’s finish up our look at the editorial in a sports medicine journal that says exercise will not help you lose weight.

While the headline certainly gets our attention, the authors really want to talk about the increase in refined carbohydrates as the cause of the obesity epidemic. I don’t disagree, but I disagree with how they’re doing it. They began by talking about an exercise myth and weight loss which was completely unnecessary. Then they ramble on about how the refined-food industry is using advertising tactics similar to the tobacco industry. The public is intentionally . . .

The Exercise Myth

/in /by

I often begin the week’s messages by responding to a health headline gone crazy. The headline generally sensationalizes what’s in the article, usually supported with press releases with similar headlines. Not in this case; every headline I read was spot on.

Here’s the actual title of the editorial published in the British Journal of Sports Medicine.

It Is Time to Bust the Myth of Physical Inactivity and Obesity: You Cannot Outrun a Bad Diet

Before I go further, ask yourself a question: do you believe that if you exercised . . .

Weight Loss Supplement: The Bottom Line

/in /by

Based on Thursday’s memo regarding the lack of any research on the effectiveness of Acacia rigidula and the chemical ingredient β-methylphenylethylamine (BMPEA), why did this get so much press? After all, there’s no evidence people are dropping in the streets because they’ve used this chemical. I think it’s directly due to the passion of a single science writer and the lack of follow-up by the FDA. I can’t be sure, of course, but let me lay it out for you.

Let’s start with the FDA. When they found supplements tainted with BMPEA a . . .

Weight Loss Supplement: The Research

/in /by

Purported experts say one thing about the amphetamine-like weight loss supplement that’s in the news. Manufacturers say another. The FDA basically says nothing. “What the heck is going on around here?” is one of my favorite Vince Lombardi quotes. I’ll break things down into three questions.

Is there any evidence that Acacia rigidula contains amphetamine-like chemicals?
Yes. The research was based on analyses of the edible parts of the plants that were eaten by animals in times of drought. Everything from caffeine to nicotine to many forms of amphetamine alkaloids were identified in the . . .

Weight Loss Supplement: The Acacia Rigidula Headline

/in /by

Science by headline is becoming more and more common; case in point, the headlines said things such as “New Study Reports Untested Amphetamine-like Substance in Weight Loss Supplement!” I just can’t let that one go, so that’s the subject of this week’s messages.

Let’s begin with the study. Researchers tested 21 weight loss supplements that contained an ingredient called Acacia rigidula. Never heard of it? Neither did I. It’s a type of bush commonly known as blackbrush acacia that grows in Texas and Mexico and purportedly has similar properties to the banned herb ephedra . . .

Weight Loss: A Better Solution

/in /by

Wrapping up our look at the research paper that examined the effectiveness of commercial weight loss programs, I think the authors dropped the ball. Yes, they did what they intended to do: review the research on weight loss programs with the purpose of being able to point physicians to effective programs based on the evidence. But that ends up being lame. All they did was provide an outside source the physicians could recommend; they completely ignored the idea of physicians providing weight loss programs within the medical practice.

Although the authors were all physicians or physicians in training, they think . . .

Weight Loss: The Problem with the Study

/in /by

Continuing our look at the recently published study “Efficacy of Commercial Weight-Loss Programs: An Updated Systematic Review,” there was a significant problem with the study and most likely, not in the way you might think. I saw no problem with the statistics or measurement variables as sometimes happens. It wasn’t a meta-analysis, so there were no issues in study selection. In my opinion, it goes back to the intent of the study.

In an editorial in the same edition of the journal, the author reported that the U.S. Preventive Services Task Force, the American Heart Association . . .
