Question Time: Professional Help

/in /by

Wrapping up this week on recently asked questions, I saved the most serious question for today. I talked to a number of people who were concerned about themselves, friends, or family members. The simplest way of explaining the questions is to say they or people they knew had medical issues related to nutrition and diet, and the inability to resolve health and eating issues may have contributed to a state of depression and anxiety.

Note that I said “may have.” This is not my area of expertise. I wouldn’t presume that I know enough to be able to say . . .

Question Time: Cracking Knuckles

/in /by

Got an interesting question last weekend from a parent regarding her 13-year-old son: it seems every joint in his body snaps, crackles, and pops when he moves. That ties in with a question I’m asked all the time. Does “cracking” your knuckles harm the joints?

Let’s talk about the teenager first. My question to Mom was, “Does he say it hurts?” She said no. I said don’t worry about; he might make less noise if he worked on flexibility, but it shouldn’t be a problem. There’s always a possibility that one of the . . .

Question Time: The Scoop on Poop

/in /by

Spending the past two weekends on the road, I got asked a lot of questions, and in some cases, I’m asked the same questions several times. This week, I’m selecting the top three questions and answering them for everyone. Let's begin with this question: how many bowel movements per day are normal?

The question came from people who were concerned they’re eliminating too many times or not enough. I know some television doctors and websites talk endlessly about bowel movements; not to be indelicate, they talk on and on about frequency, color, floating or not, and . . .

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 . . .

Physical Activity vs. Exercise

/in /by

The authors of the editorial mentioned in the last memo suggest you’re being sold a bill of goods on the benefits of exercise as it relates to losing weight. In the opening paragraph, they state that a recently published paper claimed that 30 minutes of moderate exercise five days a week is a miracle cure for reducing the risk of and treating chronic disease. They then say that physical activity reduces the risk of developing cardiovascular disease, type 2 diabetes, dementia, and some cancers by at least 30%. Then they say physical activity is not effective to help people . . .

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 . . .
