Overeating Doesn't Cause Obesity? | Educational Video | Biolayne | Layne Norton

This paper was a narrative review (ie opinion piece) regarding the Carb-Insulin Model (CIM) of obesity and it's many criticisms. While this opinion piece received a lot of press, it STILL did not address the core criticisms of the CIM, nor does it change the overwhelming evidence against the CIM.

Briefly: The CIM argues that overeating is NOT what makes people fat. Rather that high glycemic carbohydrate consumption, leading to elevated insulin levels, traps fat in adipose tissue. This trapping of fat causes fuel to be less available to the rest of the body, and people overeat in response. In other words, we don't get fat because we overeat, we overeat because we get fat.

Intriguing theory (read: CONVOLUTED) but it is NOT supported by a plethora of data.

In this video I directly address Ludwig & colleagues claims regarding energy balance and their claims regarding the CIM

Dietary carb & sugar intake has DECREASED over the last 2 decades while obesity has continued to rise:

Our caloric intake has increased by ~25% over the last half century and oil intake alone accounts for over half of the increased calorie intake

Sugar does NOT cause fat gain unless also accompanied by an increase in calories:

Low Carb Diets do not cause more weight loss than low fat diets when calories and protein are equated:

Insulin secretion explains between 1-10% of future weight gain (though this has not been supported by other mendelian randomization studies):

Other critiques of of the CIM
Inhibiting fatty acid release from fat cells does NOT impede weight loss:

Semaglutide increases postprandial insulin secretion by 2-3 fold but DECREASES fat mass:

Overfeeding carbohydrate or fats are both equally fattening in humans:

@3:13 - "as if we don't have hundreds of controlled trials"

Layne reminded me of the time Taubes and Attia went through 13 (or was it 17?) met ward studies and found reason to reject every one.

When Hall's study (which addressed many of their "genuinely[1] held concerns"), proved Taubes wrong as usual of course Taubes moved the goal posts.

[1] nothing about Taubes is genuine.

You posted on IG a while back about how you are not sure how you make a difference, this is how you make a difference. As a previous follower of Taubes and Ludwig and Fung and them all, including reading many of their books. When I stumbled across you and started watching your content, it helped me go with what my gut was telling me. I'm someone who loves oatmeal and sweet potatoes and just like the guy you referenced I believed that it was my insulin and carbs that made me fat and yet I kept gaining weight eating only 25g of total carbs a day. So thank you. And it is amazing how when I buy into an idea how delusional and prejudiced I become.

Watching this while I eat my protein oatmeal with a side of cookies :). I used to be so afraid of carbs and always struggled with food (and used to be overweight). Once I educated myself and followed people like you, I am now able to eat all foods I want in moderation while hitting my body composition goals and strength goals at the gym 💪

[filosofodemierda]

I did low carb for about 3 years and it helped. I did however realized that the main reason why it did was because of an overall reduction of calories not so much because of the low carb itself. Now I am, based on what I have learned and personal experience, being more conscious on food quantities and of course quality as well as my level of activity on a particular day.

Another gorgeous evisceration. I’ll be having a cookie after my turkey chili dinner tonight. 💖

What a breath of fresh air!
This explains why Asian cultures stay slim as traditionally, they eat less. The social etiquette of stopping to eat before your plate is empty.. I saw a wonderful Korean documentary where overweight people who admittedly were obsessed with eating large quantities of food, a tiny minority, submitted to the sparse and thoughtful monks' diet. Of course they lost weight.
Consumption of noodles and rice as a staple does not result in obesity without over eating. Portions are smaller. The satiety of many of Asian foods is based on an appreciation of delicate preparation and 'umami', satiation by great flavor instead of great volume. 
You are a gift, Layne.

This should be a series. Call it: Layne roasts stupid papers.

[Truckngirl]

It took me seven months to figure this out. I stalled so bad on the keto, I didn't lose a pound for over 30 days, even going to the gym four days a week. WTF? As soon as I went CICO and added some carbs, my weight loss is back on track. Thanks for reinforcing physics! (I know this is anecdotal, but I'm not special!)

[Ms.AnnThropic]

This is awesome! I saw this paper all over google news and was laughing as soon as I read the headlines. I was hoping Layne would do this video.

[Cymricus]

been consistently losing 8-10 lbs a month ever since i started lifting and eating 1g protein per pound lbm spread out. glad i started watching you and similar videos. lotta bull out there to get through but this is one of my favorite series to remind me it’s really just about weighing/tracking that food deficit and getting that protein. rest falls into place pretty easily.

[ExerciseCheatMeals]

Lmao the sarcasm in this is great. 😂😂😂 It’s been a while since we’ve gotten a 30 minute debunking. Thank you Layne.

[yoijoe]

To me that's all comes down to people don't want to be responsible for themselves and they want to come up with any any excuse to not take responsibility for overeating and not taking care of themselves

[NemMak]

This is the gold standard of research critiquing. If only academic institutions taught us how to interpret and analyze research the way Layne does it.

[JoseGraoFitness]

Potatoes have been a key food for me to continue my calorie deficit ling enough. Potatoes allow to add low calories volume while enjoying my food.

Compared with other high carb foods, potatoes are very filling. They scored nearly 7 times higher than croissants.

A scale called the satiety Index measures this effect. It was developed in a 1995 study that tested 240-calorie servings of 38 foods. In fact, boiled potatoes scored a 323 on the satiety index, which is the highest number of all 38 foods tested.

The best channel on YouTube. Despite not having millions of followers. They're on their way, Layne!

[thibautmuzart]

Very well done review (and debunking) of this paper! Methodological, researched, thorough, and easy to understand. Hats off! And thank you.

Lustig had me hook, line and sinker for a while. I think some of his concepts about eating real food and staying around the exterior of the grocery store are enlightening to some extent, but, I have had so much more success on my current cut by equating my calories. I have switched to a protein focused diet (180-200g per day) and filled in my remaining calories with food that is satiating. I have dropped from 205-195 over the last 5 weeks, finally breaking through a plateau I've been stuck at for quite a while.

The best thing that Lanye preaches is to have something you can adhere to and stick with long term. Right now I can sneak a keto style ice cream which has high protein or snack on popcorn and cheese when I build it into my day. I am looking forward to the next 5 weeks on my cut and trying to break into the 180's.

[Persto]

I’m so glad I found this channel. My journey started with MPMD and Greg Doucette, and now I landed up here! Thank you for the well put together presentation

[thejonathandoan]

Great stuff, Doc! I can attest to the fact that if you’ve never actually tracked your calorie intake, & live a sedentary lifestyle, it is definitely super easy to take in FAR TOO MANY calories. I think a lot of people simply aren’t aware of just how easy it is to take in a crap-ton of calories in our world today. Once you become knowledgeable of what you’re taking in, it becomes easier to cut back & thus begin to lose weight. Add in resistance training using progressive overload, & continue the process over time, you’ll be on the right track.

YouTube needs to add a new icon for a 2nd thumbs up or a “super” thumbs up. Norton’s info is not only educational but entertaining. Even my wife, who was within earshot, was cracking up. Love your stuff Layne. You should have 50 million subscribers
