Normally I wouldn't promote a show like this on a blog like this, but a recent client shared that last season a woman was diagnosed with PCOS after competing. She happens to be someone who really struggled with weight loss during the competition. My client shared with me, that she remembered thinking when hearing about the PCOS diagnosis,"Wow, if a show of experts can't even help someone like me, I don't have much hope."
Until that conversation, I'd kept my thoughts about this show primarily to myself, but realizing it may be important to provide hope to a segment of the population for whom this show may not be entirely productive…I've decided to make it a regular blog entry throughout this season of Biggest Loser.
And, I have a team of experts to help! The contributors to this blog will be taking turns sharing their thoughts, expertise, and insights. We'll be so much better at this with all of these viewpoints than if it was just me. I hope you enjoy our little series.
Now, about Episode One.
I'm going to use my turn to talk about something that has bothered me since the show's inception--how"progress" is described. Weight loss is the only measurement used in this competition. And it is never mentioned, anywhere, anytime, that weight consists of several things: fat, muscle, water, glycogen (how carbohydrate is stored) and bone, primarily.
At one point in the show, Jillian was showing how the Body Bugg works. She stated that the calories burned in a typical day are about 3,000. One pound of fat equals 3,500 calories. So if we use her statement and calculate out a week, the average Biggest Loser contestant burns 21,000 calories in one week. That works out to about 6 pounds. Any loss over that is coming primarily from water and possibly even muscle.
In my exercise physiology program, we learned that different fuels are burned at different intensities. The more intense the exercise, the more likely it is that fat is not being burned. At high exercise intensities, the body switches to burning carbohydrate, which it gets from breaking down glycogen. Each gram of glycogen is stored with 3 grams of water. So at the intensities I saw in this episode (which involved working so hard that some people literally fell off of treadmills while others retreated to corners to vomit), my guess is that fat is not what was burned.
Remember, this is a commercial television show that depends on ratings. Higher weight losses draw in bigger audiences and more advertising dollars, so what are you going to do to get there if time only permits a"measly" 6 pounds a week of weight loss? You're going to do what it takes to purge as much water and glycogen out of the body as you possibly can. I realize purging is a bad pun given the fact that people were throwing up, but it leaves me wondering if the trainers are truly aiming for health, or if they are focused on goals outside of the welfare of the contestants.
It seems to me, especially since two contestants this season aren't even cleared to fully exercise because of medical risk, that there would be some sort of attention paid to calculating target heart rates and staying in the AEROBIC range in order to maximize loss of body FAT. But then my goal would be the long term health of the person I'm working with, not my professional reputation in a televised weight loss competition.
When working with women with PCOS, I always have to keep in mind that they hit the top of their aerobic range at lower levels of exercise intensity than other women. They tend to be those clients who exercise harder and longer than anyone else…only to gain weight. It is one of the hardest things I do in this kind of work, to convince my clients to trust that if they drop the intensity, it will help to facilitate the right kind of weight loss. Especially when competitions like this one push for the exact opposite mentality.
But the wall these contestants always hit a few weeks into the season? It's about having completely run out of glycogen to purge, muscle weight gain that is occurring at the same time fat is lost, and more rapidly if target exercise heart rates are not respected.
If the measurements used to calculate progress were a combination of weight AND a body fat measurement from which total muscle gained and total fat lost were factored in, you'd see very different results. You'd probably also see a lot higher self-esteem in the contestants and fewer contestants trying to throw the weigh-ins with water loading when they start to panic about whether or not their hard work will show up on the scale.
If you're one of those people who tends to lose weight slowly or even gain weight when you feel like you've really worked hard, try this.
1. Calculate your target heart rate as follows.
-Subtract your current age from 220. This is your maximum heart rate.
-Multiply your maximum heart rate by.6, and then by.8.
-The numbers you get when you do that are the lower and upper heart rates
you need to be in, in order to be most efficiently burning fat.
2. The next time you exercise, stop a few times and take your pulse. If your heart rate is exceeding the upper limit of your target heart range, you need to drop your exercise intensity.
Many women I've challenged to do this are very surprised at how less intensely they need to exercise. And how much more pleasant exercising can be when it doesn't have to entail losing your lunch in front of a crowd of people.
