When you don't eat according to what you need, so when you restrict your intake below maintenance levels,

then you're going to be less active. So not eating according to what you need and uses a reduction of your physical activity level.

And this is an effect you only see in a negative energy balance.

So when you, after weight loss, may get to a stable weight, you get in a weight maintenance situation again.

Then this reduction is not visible anymore,

so then you get to your normal activity level.

But during a negative energy balance, you tend to get less active. Hello and welcome to another episode of Sigma Nutrition Radio.

And as always, I am your host, Danny Lennon. Thank you so much for listening

into the podcast. We are here at episode 175. And in a moment, I'm going to be talking to a researcher

who truly is a legend of human metabolism research, Professor Class Vesterverb.

Professor Vesteverp is a professor of human energetics at Maastricht University in the Netherlands,

and his field of expertise is energy metabolism, physical activity, food intake and body composition,

and then how energy balance under controlled

conditions plays out in daily life.

Like I said, a true kind of legend of this field, he started doing research way, way back

in like the 1970s on animal energetics originally before moving into human energy metabolism and activity in the

1980s. And he's been churning out research ever since, like I say, a truly eminent researcher.

So I cannot wait to get him on and talk about some of the research that he's been doing.

But just before we start the interview, let me just very quickly

mention something that will be of interest to those you interested in powerlifting and are

based in Europe. So the European powerlifting conference is being held in Ireland this July.

And over two days, you can experience world-class information presented by Mike
