High-Protein Diets Impair Insulin Sensitivity

High-Protein Diets Impair Insulin Sensitivity

Dr. Michelle McMacken: This is an incredibly
illustrative and landmark study because it shows that losing weight is not…All plans
for weight loss are not created equal when it comes to metabolic benefit. So you can do all the work of losing weight
on a high protein diet and not eat any of the carbohydrate-rich foods that you love
and still be just as insulin resistant as when you started. That’s what this study shows. Robby: You just heard Dr. Michelle McMacken
right there talk about a very important study. So we’re going to go over that in this video
today. I’ve talked about this many times. It’s our mission here. We’re going to go into individual studies
in detail, explain them, and find the takeaway message. At the end of the day, once we’ve done hundreds
of these we’ll be able to compile a clear view of what the peer-reviewed research says
about what reverses insulin resistance. So, this is an important study. I’ve been emailing Dr. Michelle about this
for a while, and I got Tara involved to really summarize the study, bring it all home so
we can learn from it and see exactly what happened in this study. So, I’m going to turn it over to Tara and
let’s all learn and see what’s going on here. Tara: So this study looked at weight loss
in two different low calorie diets. One was a high protein diet and the other
one was still a calorie-restricted diet but really along the lines of a Standard American
Diet. And this study asked the question, “What happens
to insulin sensitivity when someone loses weight?” Insulin sensitivity is the body’s ability
to utilize insulin. In a healthy body, when insulin is secreted
— it’s a hormone that tells the muscle cells to open up and let glucose into the cell — but
if someone is experiencing insulin resistance, then the cells never get that message. And so the glucose is just left circulating
through the blood, which leaves to high blood glucose or maybe you’ve heard it called high
blood sugars or hyperglycemia. So usually weight loss is associated with
an increase in insulin sensitivity. If someone with prediabetes, let’s say, were
to lose weight, then you would see an improvement in the way that their body utilizes insulin. And in this study that is what you did see
in the Standard American Diet weight loss group. When they lose weight, their insulin sensitivity
increased. But the group that was losing weight on a
high protein diet did not see this effect. In fact, not only did their body not have
an increase in insulin sensitivity, it actually had a decrease and they became more insulin
resistant. Let me just say this again because it’s really
important. The group that ate a high protein diet — even
though it was a calorie restriction diet and they lost 10% of their body weight — they
became more insulin resistant. So this is really important because a low
carbohydrate high protein diet is the standard dietary recommendation given to people who
have some form of diabetes. But this study shows that that way of eating
actually worsens the condition that those people are dealing with. There were another of other ways in which
the high protein diet fell short. The Standard American Diet protein group saw
an increase in glucose metabolism and they also saw a decrease in oxidative stress. Whereas, the high protein group did not see
any increase in glucose metabolism and they actually saw their oxidative stress get worse. And if you don’t know what oxidative stress
is, think cancer and inflammation. So the main take home point that was made
by this study and that we’re trying to emphasize here in this video is that we need to re-think
recommending a high protein diet to people dealing with some form of diabetes. Because even if they lose weight, if they’re
eating a high protein diet they’re going to worsen the disease process within their bodies. Robby: Yes, that is exactly the case, Tara. So there’s a bigger discussion here. And this is just one study. So we’re not trying to draw conclusions from
one study. We’re just going to over time we’re going
to build and show you what is in the peer-reviewed research. This study is very simply, very objectively
showing the objective numbers what happened when a group had a lot of protein and the
other group — the Standard American approach was still too much protein than what we’re
teaching here — but it was less than the higher protein group. So that’s what happened in this particular
study. No study is perfect. The more you look at these studies, the more
you see the flaws. But there are still aspects that we can pull
from. There are still factual information that happened
in these studies and when you look at tens of thousands of them as you’ll see people
like Colin Campbell and the whole the experts that we’re sorta standing on the shoulders
of and Caldwell Esselstein and Dean Ornish and all these people. You’ll see that they have spent their career
looking at hundreds and hundreds and hundreds — thousands of studies — and then they sorta
pull them all together and say “Wait a minute. This is what the research is showing.” So bottom line, this study showed that people
who ate the excess protein — even though they lost weight — they still were experiencing
insulin resistance. And that’s the bottom line. That’s what you need to know. If you want to learn how to reverse insulin
resistance, you’ve got to subscribe to this You Tube channel. We’re going to have a lot more information
on this topic, a lot more science, a lot more peer-reviewed research, testimonials from
our clients, testimonials from other physicians practicing this way. We will show you how to truly reverse insulin
resistance. Tara: And if you guys want to look more into
this study, we’re going to put some notes below and we’re going to put a link to the
actual study so that you can read it and you can take a look for yourself and make your
own conclusions. We’re just giving you guys a spark and a tear
so that you can understand what we’re shown. Robby: Absolutely. Let’s have a discussion about this. We totally geeked out on this. We went deep. I mean I could talk about this study for like
an hour. Tara. Yeah. Robby: We’re just pulling out the important
points and important conclusions. Check it out for yourself. Tara: Please ask some questions below. We’d love to make this a longer discussion. Yeah, please. Robby. Absolutely. We’ll see you in the next video.
