Nuts Don’t Cause Weight Gain?!?

Summary:

  • Flawed Research Studies (0:55 – 2:06): Nelson explains that many studies used to support the claim that nuts are weight-neutral were actually cholesterol studies where participants were strictly monitored and had their food intake reduced if they began to gain weight. Therefore, these studies were engineered to prevent weight gain, not to test if nuts cause it.
  • The “Expected Weight Gain” Fallacy (2:37 – 4:42): When the initial claim was challenged, some nutrition experts shifted the narrative to say nuts don’t cause the “expected” weight gain. Nelson argues that this relies on a flawed mathematical model (the “3,500 calorie rule”) that does not accurately predict human weight changes.
  • Common Marketing Tactics (4:43 – 8:30): The video highlights how the same logic—finding a gap between predicted and actual weight gain—is currently used to market other calorie-dense foods like avocados, full-fat dairy, and chocolate. He points out that this phenomenon is not unique to these foods; adding any 300 calories of food, including broccoli, would show similar results because of how the body naturally compensates.
  • Real-World Impact (9:00 – 10:45): Nelson emphasizes that for many people, including himself, consuming calorie-dense foods like nuts without restriction does lead to weight gain. He advises viewers to be skeptical of nutrition headlines by asking three questions: Was the food added or substituted? Is the “expected” weight gain based on a reliable model? And who paid for the study?

Gut Bacteria May Reveal How a Western Diet Fuels Colon Cancer : ScienceAlert

Aug 5, 2026

Colorectal cancer is one of the most common cancers worldwide, and what we eat can significantly influence our risk of developing it.

Western-style diets, typically high in fat and meat but low in fiber, have long been linked to a higher risk of the disease. But exactly how this pattern of eating may encourage tumors to develop has remained unclear.

A new study published in the journal Gut may have taken us a step closer to understanding the exact mechanism at play.

The study suggests that certain gut bacteria in the depths of our bowels, sustained by Western-style diets, may produce a substance that promotes tumor growth.

[…]

For now, the findings reinforce existing dietary advice rather than establishing a new treatment: Diets rich in fiber, fruit, vegetables, and whole grains, and lower in processed and red meat, are associated with a reduced risk of colorectal cancer.

The study was published in Gut.

Cool Your Starches!

Fascinating! Freezing bread and toasting it from frozen forms resistant starch, which studies show can reduce the blood sugar spike compared to fresh bread (freezing alone cut the spike by about a third).

When starch is cooled, then reheated, it acts more like fiber than sugar, feeding good gut bacteria along the way.

It also works for pasta, rice, potatoes, etc.
