Welcome to the Shaline Show. Shaline is a New York Times best-selling author, celebrity fitness trainer, and obsessed with helping you live your dream life.

Hey there! Welcome to this edition of the Shaline Show. I am so excited for you. I'm always excited for you to be here, but today I'm really excited for you to hear from my guest.

Dr. Michael Bruce, known as the Sleep Doctor. He's a clinical psychologist, the author of Sleep Doctors' Diet Plan, and one of my recent favorites, The Power of When.

You've seen him on CNN, Oprah, The View, Anderson Cooper, Rachel Ray, Fox and Friends nearly 30 times on The Doctors, the CBS Early Show, The Today Show, Kelly Michael, just to name a few.

What I love about Dr. Bruce, aside from the fact that he says, dude, which dude I think is so cool, is his approach to weight loss and understanding how our Sleep Effects are hormones.

This is a two-part episode. The first part will blow your mind and have you craving part two off to the show.

Dr. Bruce, it's an honor and a pleasure to have you on the show today.

Thank you. I'm excited to be here. This has been a hot topic for some time with my audience. Well, and actually, of course, for me too.

Understanding how sleep correlates to weight is, I think, a new piece for so many people. I assume that from the time we were pretty young, our parents are telling us you need to get out of

the way to sleep. That's just a message we tend to believe because you can feel it. I think the correlation between weight and sleep is something that's relatively new.

I want to come right out of the gates and have you explain to us why and how in the world the sleep effect are weight.

It's fairly interesting. The data has really started to come into its own within the last 10 or so years.

There are four ways that we know that sleep deprivation affects our ability to lose weight or to maintain a healthy weight.

Just to give everybody an idea of what I mean by sleep deprivation, while it does partially mean the number of minutes or hours of sleep that you get,

it also has to do with the quality of the sleep that you get. It's not just a quantity issue, but it's a quality issue as well.

There are lots of reasons why you might have poor quality sleep. I can't count the number of patients who have shown up in my office and said,

Dr. Bruce, I'm sleeping seven, seven and a half, eight, eight and a half hours and I can't lose weight and I feel terrible. What the heck is going on?

It turns out that they have an underlying sleep disorder like sleep apnea or they have a thyroid issue like Hashimoto's hypothyroidism or something like that.

Anything that deprives you of quality or quantity sleep is what I'm calling sleep deprivation.

Now, once we understand that definition, the thing you have to realize is there's four different areas that have affected us in terms of weight.

So first of all, when we're sleep deprived, our metabolism slows down and actually doesn't expend the energy that we normally would have happen.

Why is that?
