What Are the Pros and Cons of Protein? | Dr. Robert Lustig

Levels Advisor Robert Lustig, MD, explains why protein and exercise are crucial for metabolic health.

Sarcopenia is age-related muscle loss. Sarcopenia leads to metabolic syndrome, declining health, and early death.

Protein is a macronutrient that, in conjunction with exercise (e.g., resistance training), helps build and preserve muscle to prevent sarcopenia.

Protein in meals helps mitigate glucose spikes because it slows the absorption of glucose into the bloodstream.

Twenty amino acids make up the different types of proteins we consume. Nine are essential proteins, meaning the body can’t make them, and we must get them from food.

Leucine, one of the essential amino acids, stimulates muscle protein synthesis, so it’s necessary for preserving and building muscle.

However, without exercise, leucine stimulates insulin release and contributes to high insulin levels, which can drive fat gain.

Leucine is found in high amounts in milk and corn-fed animal products.

I am so thankful for people speaking out about how to keep our bodies healthy!!! They don't have to do it. ❤

[Pramono]

Yes sir I understand better now so I will take more execise well thanks a lot from Indonesia

[anitaelghandor]

Thank you so much, we appreciate you.😁👋🌟🌟🌟🌟

[TroyBurnett-jkwr]

Doctor Robert is one of the smartest people out theyes.His book was outstanding.What a rock star

[ardnfast]

I'm glad you left out carbs, but protein, exercise, and fat are crucial for metabolic health 🙏

[crzyu]

I like to eat that protein, sure. Now I know to take exercise more seriously. Thank you Dr Robert.

[juhungshao]

Love all you have shared and thank you ❤

[oldpoet]

Expand on Leucine and the pathways of proteins and amino acids😊

[SPDATA]

Even more important as you getting older.

[ccmkoho]

Well, you only have two other choices. Carbs and fats. All proteins aren’t the same, you want a complete amino acid profile, usually satisfied by meat or fish

Insulin isn’t always a bad thing ! In factinsulin can help the body synthesize more muscle protein, which is essential for building and repairing muscle tissue.
Enhanced Nutrient Uptake:
Insulin facilitates the transport of glucose and amino acids into muscle cells, providing the building blocks for muscle growth.
Reduced Muscle Breakdown:
Insulin can help prevent the breakdown of muscle protein, creating a more favorable environment for muscle growth.
Increased Blood Flow:
Insulin can improve blood flow to muscles, delivering more nutrients and oxygen. But on the contrary insuline spike due to excess sugar and carbohydrates can lead to long term health problems like diabetes .

How much protein do you need to prevent sarcopenia? What are the consequences of too much protein?

[kelsryosun]

Leucine over consumption blunts autophagy if you fast 16:8.

[PrinceLorenzGabonada]

Great, together with the right nutrient timing. Protein is the organ of longevity💪🏻🔥

What if I have a neurodegenerative disease (which I do: Bulbar-onset ALS) that results in muscle atrophy, from neurons not communicating with my muscles? I can stretch, but hardly what you'd consider muscle-building exercise.

[NosinaDevajeevamani]

Good morning sir I am from India please help me how to reduce my sugar sugar level is 6.4 food I have to take please mention it which tablet I have to take

[lendvainorbert]

It's protein and training. With exercise you don't build muscles, except you're coming out of coma, or something.

[WendyWertz-qv]

Why is the good Doctor got a lot of belly fat that’s very apparent ❤

[Faitful]

For hypothyroidism people can they eat proteins some they said proteins are not good some they said the apposite please what’s the right thing to do because without protein u can’t loose weight
God bless all
