Why Sugar Is Problematic for Metabolic Health | Dr. Robert Lustig Ultimate Guide

Levels Advisor Robert Lustig, MD, explains why added sugar, especially fructose, is harmful.

There are 262 names for sugar, and the food industry uses all of them, which makes eliminating added sugar from your diet tricky.

What you need to know about fructose:

- Fructose stimulates the reward center in the brain, making it highly addictive.
- Fructose and alcohol are metabolized in the same way.
- Fructose and alcohol both may lead to Alzheimer’s disease.
- Fructose inhibits mitochondria, the powerhouse of cells, from doing their work well.
- Fructose does not show up via continuous glucose monitoring (CGM).
- There is no biological reaction in any vertebrate organism that requires dietary fructose.

✅ What you can do:

- Avoid added sugars as much as possible.
- The occasional dessert is not harmful, nor is fruit.
- However, many people are consuming too much added fructose meal after meal.

I love you Dr Robert Lustig!! Thank you for helping us understand the trap that we are in and for showing us the way out. Thank you for standing up against the “processed foods giants “ for a better future for mankind!!

This should be illegal. People need to be held accountable and go to jail for literally killing people if they’re hiding it in other names and it’s not visible that is pretty messed up for health conscious people that read labels, but they don’t know what the heck they’re reading that’s why we shouldn’t eat things in boxes and packages. Thank you for this information.❤

Twenty-seven months ago, I jettisoned ALL forms of sugar, including fruit, from my life. I eat zero carbs, zero plant matter, zero seed oils (canola, soy, corn, & etc.), zero fiber. I eat the Carnivore way, 100 percent animal products. I'm 76 and am now experiencing excellent health for the first time in my life. I've reversed T2 diabetes, high blood pressure, brain fog, lost 45-pounds, and on and on. Even my 45-year multiple chemical sensitivity issue has completely gone away. I attribute all of this to healing my leaky gut caused by inflammatory foods. I'll never go back to eating ANY form of highly addictive sugars.

While I agree with much of what is said here, there is a lot of deeper information on sugars freely and easily available. There are essential fatty acids and amino acids. There are NO essential carbohydrates. Side note: Please don't fall into the "net carb" trap. Thank you for the info you shared, Dr Lustig.

Hilarious summary right at the end 😂
"Bottom line, if you want dessert, have dessert. Just don't have dessert for breakfast, lunch, dinner and snacks. 😂

Can we eat fruits as apples, pears, cherries as desert?

[susanareid]

So how much fructose in one large banana, some papaya and a handful of berries? …. I ❤️ fruit
I don’t consume any sugar and I have high cholesterol …..

[janetmcg]

When the ‘nutrition information’ on the side of a package states the amount of sugar added, or states ‘no added sugar’, does the word ‘sugar’ refer to any of the 262 forms of sugars or does it only refer to what is commonly known as ‘table sugar’?

I Cook everything, Nevermind the type of sugar.

[robhutter]

So fructose is in fruit . Should we cut out fruit ?

[bradleycampbell]

What about fructose in fruit, like apple's, is fruit ok to consume

[DonCE]

is the reason cgm does not measure fructose because the body uses glucose as the most preferred source of energy?

[Alabastergirl]

Why does he not say fruit if fructose?

[ClassicJukeboxBand]

Lustig and Richard Johnson should both try carnivore...

[bungkusi]

What about the "fake sugar"
The sugar for diabetics patient

[ricmrodrigues]

If you want dessert, eat another steak, you're not done with your email 😂
