Why Ultra-Processed Foods Cause Weight Gain

Dr. Zachary Knight and Dr. Andrew Huberman discuss why ultra-processed foods cause weight gain.

Dr. Zachary Knight is a professor of physiology at the University of California, San Francisco (UCSF), and Howard Hughes Medical Institute (HHMI) investigator. Dr. Andrew Huberman is a tenured professor of neurobiology and ophthalmology at Stanford University School of Medicine and host of the Huberman Lab podcast.

So interesting how he explains sensory specific satiety . Such a great interview .

[NewMateo]

It doesn't have to get this complicated. Processed carbs increase grhelin while high protein foods increase leptin and make you feel full longer. We've known this in nutritional science for a long time.

Weight loss and weight gain are both the easiest and the hardest things in my life.

Every time I gained lots of weight was when I was too stressed and anxious that led me to (consciously and unconsciously) consume copious of fat + carbs; e.g. multiple plates of spaghetti in one sitting (which has plenty veg oil and beef fat in it) or I ate jam + butter toast / bread to a point that I was physically uncomfortable and not because I felt satiated.
UPF definitely makes the situation worse, but it's not even close to stress and anxiety. Sleep is another big factor to fight against.

And every time I lost lots of weight, was due to help of ketosis / fasting, some endurance physical activity like long distance cycling, more sleep and having very little anxiety.

The diet Huberman illustrates is a basic version of the Atkins diet - limited carbohydrate higher protein. Then, adding CHO foods back into diet.

[jacobbradsher]

I don’t believe this is correct. The study he is referencing didn’t standardize for palatability but for calories and macros.

The UPF had the higher palatability and therefore is hypothesized led to overconsumption of calories daily, approximately 500 calories per day.

I quit drinking diet soda completely and within a month (my only source of artificial sweetners) I lost 10 lbs without changing anything else and it has stayed off. This is the first time since I was probably 22 years old that I've gone this long without any diet soda and the weight has not come back still (after several months). I did not start exercising. I did not stop other sweets.

There are economic incentives to process food. Simple healthy food from the farm is too simple, doesn’t create enough jobs etc. but our health is more important!

Can you talk about auto immune disorders?

I've cut out chocolate bars (and tried to reduce most other forms of sugar) recently. I had a kit kat (small one) the other day and it tasted so different I couldn't finish it.

[DrJuliusG]

Don’t consume anything in concentrated form. No refined powders. No extracted liquids. You’re welcome.

[saimon]

We literally give children blended whole foods, I don't any way why that should be disgusting.

[Hypnotic]

OMG - it's all about how much artificially increased glucose you have in your circulatory system ( veins and arteries ) this people love to prolong unnecessary the facts :)

[Tony-mpv]

Seed oils

High fructose corn syrup

refined sugar or too much

Wheat gluten gliadin lectins
