At the @MetFixByBSI Foundations Course we teach fitness, health, and nutrition coaches the mechanism of this phenomenon.

As Japan-USA relationships are reaching a new all-time high, I'm loving every minute of it. As a metabolic scientist, I've loved the opportunities to speak at events in Japan. Why would an American metabolic scientist be invited? Because the metabolic problem in Japan isn't that far off from the USA. To understand this, you need to appreciate the nuanced relationship between obesity and diabetes. We often assume that fat mass matters most. However, the size of our fat cells matters more when it comes to metabolic health. Caucasians (the dominant ethnicity in the USA) have the ability to make new fat cells as they gain weight. This means their fat mass can expand while the size of the fat cells remains fairly normal. However, in East Asians, the ability to generate new fat cells is limited; thus, any fat gain pushes the fewer fat cells to be larger. And large fat cells promote metabolic dysfunction. This explains why the USA can be significantly fatter than Japan, yet have diabetes rates that are only a point or so higher.

@BizNasty2point0 I agree. I always enjoying playing the game and the tradition of baseball, but the pitch clock made me enjoy watching baseball. I am now a hardcore fan.
English
What baseball has done with pitch clock and ABS is unbelievable. One of the most traditional games making adjustments and it rewarding the fans. Just smart stuff and the online interaction from ABS can’t be denied. Bravo Baseball.

@realDaveFeldman @ChrisMasterjohn Are you familiar with Peter Dobromylskyj? If so, what is your take on his ROS hypothesis of obesity by way of PUFA intake?
English
Today I'll be interviewing @ChrisMasterjohn for the #FeldmanProtocol.
If you have any last minute questions to add to my list -- speak now or forever hold your peace.

@Lea_Christina4 As a father, thank you for sticking up for women and girls. Keep it up. Cheering you on.

This is me at the Powerlifting Worlds in 2023 lifting 507lbs. It took me years of training to achieve that and I still didn't medal, I got 4th place. Little did I know one month later I would be suspended for 2 years by my federation for speaking up about men competing in the womens category and that a man would walk in and pull a 578lb deadlift and crush womens records. He still holds records in Alberta to this day
I can only hope that with the Olympics announcement today that the Canadian government will follow suit and demand federations to protect the female category
Alberta has already started.
Sports are separated by sex
Sports are about integrity, fairness and safety. It is time we do the right thing and stop punishing those who speak up.

Seed oils increase appetite via effects on insulin sensitivity depriving the body of energy while making adipocytes lipophilic.
The double bonds in the fatty acid increase the NADH:FADH2 ratio preventing the natural reactive oxygen signal in the mitochondria from triggering satiety.
There are other data showing why they could be bad, but this is primary.
Max Lugavere@maxlugavere
Seed oils have made a lot of people very fat, but not because there’s anything special about the oil. It’s just oil, and a major source of invisible calories in modern diets. You could swap seed oils with any other oil and Americans would be just as fat.

Depends on what kind of performance. I agree with @SBakerMD 's sentiment.
Your definition of "high-output" seems more closely related to low-power endurance efforts than high-power strength efforts.
I qualified for the @CrossFitGames 2x using fasting and a low-carb diet as part of my training strategy. The crossfit effort is defined by high output – work/time.
Training @CrossFit athletes daily for 15 years, I have seen the best long-term performance benefits correlate with reducing carbs. This benefit becomes more prominent with aging athletes.
Zach Bitter@zbitter
If you are okay with a low output lifestyle, gluconeogensis works fine. When I broke the 100 mile and 12 hour WRs (high output lifestyle) following a low carbohydrate diet I was asked by some why I fueled with ~40g of carbs per hour and didn't rely on gluconeogenesis. My response, go and try to burn 12,000 calories in 12 hours relying on gluconeogenesis and let me know how it goes. Survive and performance are not the same, but often get confused.

Really cool study by @TyBealPhD
The pattern of eating optimal for the human organism seems more and more obvious the longer you study this subject.
Eat meat and vegetables, nuts and seeds, some starch, little fruit, no sugar or seed oils.
This is naturally a diet higher in fat, moderate in protein, and lower in carbohydrate density.
From what I've seen this type of diet enhances metabolic health and performance in athletes willing to be patient with adaptation.

I agree with Darius. Anabolic hormones tend to get up-regulated on moderate fasting protocols.
The other thing I think about is autophagy. It is possible that you broke down fat and got stronger at the same time. It's likely the body will rid itself of useless resources and it would make sense your energy would be allocated more efficiently thereafter! (a hypothesis)
English
@alexklint A 7-15 mile hike, especially if you were rucking or carrying any weight is still a damned good workout. And if you were fasted, HGH would be upregulated, which would help retain muscle. I suspect you were still focused on protein too. Which helps with muscle protein synthesis.
Roseville, CA 🇺🇸 English
Weight loss naturally or with GLP1 assistance, without resistance training, includes muscle loss. But I’ve had a different experience.
I spent two years hiking 7-15 miles nearly daily, typically fasted, with effectively 0 resistance training. I went from ~155lb to 140lb and was easily the leanest I’ve ever been. My strength hardly budged, and with one week of gym access I set PRs in bench and deadlift.
Theory: why would the body break down muscle unless absolutely necessary? If I’m fat adapted, my body still has energy stores even at the <8% body fat I was likely at. But most people try to lose weight without first healing their metabolism. In that metabolic state, might the body have no choice but to break down proteins to maintain glucose levels?
Thoughts @CaseyRuff @SBakerMD @MurseDarius @PeterMShaw @AKoutnik @ProfTimNoakes ?

@BenBikmanPhD @ProfTimNoakes What do you see as fructose’s major role in this pathology?
English
Fatty liver disease is the most common liver problem worldwide. But do you know where that fat comes from? The mistaken view is that this fat originates from within the liver itself (i.e., the liver creates it). While this accounts for some of the liver fat, the majority comes from fat tissue itself. But! The conditions need to be right--there are two parts of this. The first is the fat cells releasing a high amount of free fatty acids. The second is equally important: insulin levels need to be elevated.
The combination of high insulin and high free fatty acids is a metabolic anomaly--this shouldn't happen. But, it does happen when fat cells becomes insulin resistant with excess growth. In this state, the body has high insulin (always present in insulin resistance), but the too-fat fat cells don't respond to the insulin, and they continue releasing free fatty acids in the midst of the elevated insulin.
So, with fatty liver we shouldn't look at the liver itself as the problem, but rather the misbehaving fat cells.

If you have high blood pressure, it’s very likely insulin resistance is the primary driver. Via at least four distinct mechanisms, insulin resistance disrupts normal blood vessel function and hemodynamics. This is why resolving insulin resistance enables so many people to reduce or eliminate blood pressure medications.

This has been well known for decades but it isn’t because writing makes you use your brain.
It’s because writing is SLOWER than typing and efficiency and speed are the enemy of understanding.
Slowness forces the student to reword what they are writing because they have no time to write down everything and rewording requires thinking about meaning.
Typing is fast enough to write down direct quotes so it doesn’t require thinking about meaning.
Use efficiency and speed for rote things that free up time to slow down for what you want to derive meaning from.

Students who took notes by hand scored ~28% higher on conceptual questions than laptop note-takers. Writing forces your brain to process and compress ideas instead of copying them.

In my efforts to increase awareness of the relevance and prevalence of insulin resistance, I’ve justifiably called out the consumption of refined carbohydrates.
To summarize this sentiment succinctly: if the carbs come in a bag or a box with a barcode, be careful.
