The Science Behind Holiday Spices: Cloves

/in /by

No one has to tell us that Christmas and the New Year are coming; it’s in the air. You can smell the holiday season this time of year. This week, I’m going to cover three spices used this time of year and talk about some of the potential health benefits of each. I’m not suggesting their use makes foods healthy if they’re also high in sugar and fat—just that there’s some interesting science behind these spices.

Lessons from “The Biggest Loser”

/in /by

The recent study on weight gain by former participants in “The Biggest Loser” reality television show blamed decreases in resting metabolic rate (RMR): the decrease in RMR became worse over time and contributed to most of the participants regaining most of the weight. In other words, they ruined their resting metabolism.

No, they didn’t. In my opinion, there are errors in the measurements for RMR and total energy expenditure (TEE). The errors may be in the equipment, but more than likely, in the assumptions that were made in the calculations.

Here’s where I think researchers went wrong: there . . .

Rate of Change

/in /by

I spent hours looking at the data in “The Biggest Loser” study. I did numerous calculations trying to figure out where the changes in caloric use occurred that could explain the dip in resting metabolic rate that made the headlines. There are several possible explanations.

Today I’ll give you the most probable reason: the subjects lost weight too fast. The average was 4.25 pounds per week and for some, it was double that. While that can win contests, it doesn’t allow the body to adjust to the tremendous changes that should be occurring.

Think about it. There . . .

Does Weight Loss Ruin Metabolism?

/in /by

The health headlines two weeks ago were focused on what we can call “The Biggest Loser Study.” Researchers published the results of a six-year follow-up of contestants in Season 8 of the reality show “The Biggest Loser.” It turns out that most contestants gained back a significant amount of weight. Why? Based on the research, decreased resting metabolism was identified as the most likely suspect. Headlines shouted that weight loss caused metabolic rates to fall more than expected and therefore made it hard, if not impossible, to maintain weight loss.

I believe that all research has merit, even . . .

Raising HDL: Weight Loss

/in /by

Before I finish up this week’s look at HDL cholesterol, I want to wish every mother a Happy Mother’s Day. I hope it’s a great day with your children.

The number one way to increase HDL cholesterol is to lose weight. Losing fat helps increase HDL levels while simultaneously lowering LDL cholesterol. We still don’t know precisely why, but there’s really nothing debatable about it.

I’ll give you my theory of why weight loss helps raise HDL cholesterol. In order to lose weight, you have to eat less and/or move more; more than . . .

The Bottom Line on High-Fat Dairy

/in /by

If you’re a long-time reader, you know that science by headlines makes me crazy because news reports often distort the findings of the research papers to make them seem more important than they are. It doesn’t help that research institutions send out press releases that contribute to the hype of their research findings. Such is the case with the two papers I reviewed this week.

In the first paper, researchers examined blood values of fatty acids found in high-fat dairy products as potentially . . .

Gaining Muscle and Losing Fat with Protein

/in /by

Can you gain muscle while losing weight? Let’s take a look at the final study in this week’s Research Update on protein.

Researchers recruited 40 young overweight men to participate in a four-week diet and exercise weight loss program with an average age of 23 and average BMI of 29.7. The subjects were randomly divided into two groups. The control group had a diet that reduced calories by 40% and provided 1.2 grams of protein per kg of body weight per day. The protein group had their intake reduced by 40% but were given 2 . . .

Protein Intake and Sleep Quality

/in /by

Today we’re going to look at two studies from Purdue University, Paula’s alma mater, on the role of protein intake and sleep during a weight loss program (1). In the first, 14 subjects were given a diet with an increasing percentage of protein intake. After two weeks on their normal diet, subjects were put on a diet that reduced calories by 750; every four weeks, the protein content was increased, beginning with 10%, then 20%, and finally to 30% protein. Their sleep was assessed using the Pittsburg Sleep Quality test before and then after four weeks on each . . .

The Bottom Line on a Probiotic for Weight Loss: Misdirection

/in /by

One of the basic tenets of magic is misdirection. The magician gets you to look at his right hand when it’s actually his left hand that’s hiding something. I’m going to use that analogy as we finish our look at the probiotic Akkermansia muciniphila.

Let’s start with this. The microbiome of people who weigh less is different from the microbiome of those who weigh more. It seems if we could figure out what bacteria are different between those groups, we might be able to help those who weigh more lose weight. It makes sense . . .

A New Probiotic for Weight Loss?

/in /by

Weight is always a hot topic, so I’m telling you about two weight-loss studies this week. The idea is to give you some idea how the next great thing could hit the market—or it may not—but if it does, you read it here first. The potential solution is a good bacterium called Akkermansia muciniphila. This probiotic may be a key to weight loss, or it may not. Let’s take a look at the first study. I’ll only hit the highlights because these were two of the most complicated research papers I’ve . . .
