Are you saying that a diet from higher carbs will produce more fat gain than an equicaloric low carb diet?

Yes, I am saying just that. The body uses 100 calories of corn chips and Coke differently than 100 calories of bacon eaten by itself.

Read Taubes for references to the scientific literature.

The first law of thermodynamics takes issue with this. A calorie is a unit of measure for energy.

Excess calories can be stored as fat. Carbs that drive high insulin levels end up being converted to fat, and the subsequent low blood sugar level promotes more carb consumption.

This does not happen with protein and fat consumption. If you force yourself to overeat those foods in the absence of carbs, which is not easy, they will be simply eliminated.

You're saying that eating excess calories in the form of fat won't be stored as fat? That's the most efficient pathway and was critical to our survival.

What you're referring to (excess carbohydrates converted to fat) is denovo lipogenesis which is exceedingly inefficient and rare in humans.

My personal experience over several decades aligns with what Taubes explains in the first book I cited. If you want the technical details, you could read it.

You can't get fat on a diet that is strongly deficient in carbs, while it's easy to get fat on a diet containing high proportions of fat and carbs.

The Eskimo subsist on meat and blubber alone. Roald Amundsen ran the experiment on himself and confirmed it.

The group of people you're referencing (Inuit people btw, Eskimo is a slur) have some of the highest obesity rates in the world! The Nunavuts have an obesity rate of 48%!

The ethiopians have a diet of mostly carbohydrates (>70%), and are extremely lean.

Taubes is a bullshit artist who cherry picks data to sell books.

Modern Inuits. Fast food. And stuff your 'slur'. !w Eskimo.

Ethiopians are hungry.

Not the person you addressed, but people are not lab rats whose daily caloric amount is controlled by a lab technician.

We humans in rich countries eat ad libitum. Any dietary intervention that helps us feel less hungry will lead to a reduction in the calories we consume.

I never said they didn't. I said that a diet, when controlled for calorie levels, will yield identical fat gain/loss.

Of course not. The type of foods you eat affects how many calories you eat so the diets won't be equicaloric.

Well the person I responded to is claiming equicaloric diets lead to different levels of fat gain.
