What is weight cycling and why do so many people experience it?
Wow, wow, wow. So it's weird. It is true. It is true that weight cycling can mess up your metabolism. Not so fast. Hi, I'm Wendy Zuckerman and this is Science Versus.
Science Versus
Today on the show, why is it so hard to lose weight and keep it off? Plus, what happens to your body when you lose a bunch of weight and put it back on and lose a bunch of weight and put it back on? Because the internet is saying that this cycle, which is very common, is actually really, really bad for your health. But is it true? And just quickly before we get started, I do want to say that if this is a sensitive topic for you, please take care while you're listening to the show and we're going to put some resources in our show notes. Okay, to get into the science here, we have senior producer Rose Rimla. Hello, Rose.
Hi, Wendy. Where do we begin? The first thing I want to do is I want to introduce you to someone I recently talked about this quite a bit with. His name is John Rossi. He's a musician. He's actually a drummer. I called him up because he is someone who has struggled a lot with his weight.
I have been weight cycling most of my adult life, and it's not fun.
Weight cycling. So this is the term for when folks lose a bunch of weight, put it back on, lose a bunch of weight, put it back on, right? This is the new internet term that I guess in the 90s we were calling yo-yo dieting.
Yeah, I think so. I think weight cycling is like a little bit more—sounds a little more scientific or something. And so John's story is that he initially lost a lot of weight in his 20s. That was like the first time he ever lost weight. He lost quite a bit of weight, and his appearance really changed. People, he said, were complimenting him a lot. He was getting a lot of positive attention. And it changed a lot of things for him. He said it changed the way that he dressed, right? So he said that before this happened, he was wearing like dark T-shirts and baggy jeans.
And now I was wearing the most like funky pink cool stuff and skinny jeans. And I was in it to win it.
What was your wackiest outfit from that time?
I had a pink t-shirt that I like to wear with a pink flannel over shirt, like a button down over it, unbuttoned, with matching pink sunglasses. That's not pretty rad. It was so bright, and it was so good, and I miss it.
Mm-hmm.
Mm-hmm.
He eventually gained back a lot of the weight that he had lost. And so he put his pink outfit in the basement. So that was the first time. But he's since then gone through a bunch of these cycles, losing weight, gaining back weight, losing weight, gaining back weight. And he's not alone. Studies find that up to half of adults in the U.S. have gone through at least one weight cycle.
Half of all adults in the U.S. have experienced this.
Yeah, it's very common. And it's also very common for it to happen repeatedly. So another survey found that of people who do weight cycle, they go through on average eight cycles by the time they're middle-aged. And, you know, he's right on track for that average cycle.
I am currently on my ninth time trying to lose weight.
Wow. And how many pounds do you think that is over the course of your life?
I mean, if I had lost all of this together, I'd be in the negatives.
Yeah, you'd have lost your entire self.
Yeah, yeah, yeah. Like, I have lost multiple people, you know, over this time period.
In fact, he says he's lost and put on hundreds of pounds over the last couple of decades.
Mm-hmm.
Yeah. You know, John has worked so hard so many times that when this happens, it just feels awful for him.
Terrible. Like, truly, like, I was failing myself. And I was... You know, I had succeeded at something and then failed at it, which I think is probably worse than just never succeeding at something.
Why is it so hard to lose weight and keep it off?
And it's really hard. It is... I would take every other challenge in my life and double them if I could get rid of this one.
Yeah, and I heard similar things from other people who I spoke to for this episode. Listeners called in and just seemed like there was a really common theme of frustration, sadness, and then also a lot of self-blame.
