Fundamental Flaw in the Calorie Concept: The narrative begins by challenging the food industry's claim that managing weight is simply about balancing calories - calories in versus calories out. This idea leads to a chain of assumptions: obesity is due to gluttony and sloth; it's the individual's fault; diet and exercise are the sole solutions; and any calorie can fit into a balanced diet. Lustig criticizes this viewpoint as overly simplistic and misleading, arguing that it shifts responsibility onto the consumer while absolving the food industry.
The Big Lie in Medicine: Lustig, with a background from Brooklyn, New York, vehemently argues that the equivalence of all calories is the biggest lie in medicine. This lie, he says, benefits the food industry as it diverts attention from the quality of calories to their quantity.
Evidence Against the Calorie Myth: Lustig offers evidence to debunk this myth by examining four different food items - almonds, protein, fats, and sugars (fructose and glucose).
Almonds: When one consumes 160 calories of almonds, only 130 are absorbed due to the fiber content. The fiber in almonds forms a barrier in the intestines, preventing the absorption of certain calories and sugars, thereby protecting the liver and reducing insulin response. The unabsorbed calories benefit the gut microbiome rather than the individual.
Protein: Protein, when not needed for muscle building, is metabolized by the liver. This process of converting protein to energy is inefficient compared to carbohydrates, resulting in fewer ATPs (energy molecules) produced per calorie.
Fats: The speaker contrasts omega-3 fatty acids (beneficial) with trans fats (harmful), both containing nine calories per gram. This stark difference in their health impacts illustrates that not all calories have the same effect on the body.
Fructose and Glucose: These two sugars, both with four calories per gram, have vastly different effects on the body. Glucose is described as essential, while fructose is labeled a toxin.
Implications for the Food Industry: Lustig suggests that acknowledging the truth about calories - that their source and nature matter - would significantly impact the food industry. It would challenge the industry's narrative and potentially lead to legal consequences.
Impact of Fiber on Sugar Absorption: The fiber in almonds, both soluble and insoluble, creates a barrier in the duodenum, which is the first part of the small intestine. This barrier inhibits the absorption of simple sugars like glucose, fructose, and sucrose. This process helps in maintaining liver health and preventing the liver from turning excess sugar into fat.
Gut Microbiome and Calorie Utilization: The unabsorbed calories from almonds, owing to their fiber content, pass further down the intestine to the jejunum, where they become available to the gut microbiome. The gut bacteria then utilize these calories for their own purposes. Lustig emphasizes that the human gut is home to a vast number of bacteria, which play a crucial role in overall health.
Fiber's Role in Metabolic Health: By influencing the absorption of calories and sugars, fiber plays a significant role in maintaining metabolic health. It prevents excessive insulin response by reducing serum glucose response, thus keeping insulin, which can drive chronic metabolic diseases, at lower levels.
The Misleading Nature of Calorie Counting: Lustig argues that the focus on calorie counting is misleading because it ignores the critical aspect of how different foods and their components, like fiber, are processed by the body. He emphasizes that it’s not just about the number of calories consumed but also about what the body does with these calories.

All I know is that my body and my gut respond to fatty grass-fed beef.
ow does a steer get fatty by eating grass?

You surely can't be as ignorant as your troll post, can you?
Calories in minus calories out still holds true,none of the above is contradicting this. It just means some foods have lesser net calories than others, similar to net carbs, depending on the absorption/work needed to absorb. Still you can intake glucose and fructose mainly all day and lose weight as long as you burn more calories than you took in. It's basic math and thermodynamics
The error people make is why they are hungry. You can eat ice cream and drink soda all day, do this for a few days, and you'll find yourself starving for food. You know why? Because you don't have any nutrition. People are hungry because they aren't eating food, they are eating junkfood.
Golf simulator mind you but I just did a 5 over at Quintero
