You have probably seen “net carbs” on food labels or heard the term in low-carb and keto spaces. But what does it actually mean, and does it matter?

In this episode, we break down what carbohydrates are, how net carbs are calculated, where the concept came from, and why it is not formally recognized in nutrition science. We also discuss blood sugar, fiber, sugar alcohols, food marketing, and what matters more than chasing a net carb number.

If you have ever wondered whether net carbs are helpful or just another diet trend, this episode will give you the clarity you need.

Fiber is often oversimplified as something that “keeps you regular.” In reality, it plays a far more complex role in digestive health, blood glucose regulation, cholesterol management, gut microbiome diversity, and long term disease risk.

In this episode, the discussion continues the carbohydrate series by breaking down the different types of fiber, including soluble fiber, insoluble fiber, functional fiber, and resistant starch. The episode also connects fiber recommendations to the Dietary Guidelines and explains why the source of carbohydrate matters.

Carbohydrates are among the most debated nutrients in modern nutrition discussions. In this episode, fiber, starch, and sugar are clearly explained, along with how they function in the body and why they remain misunderstood.

This episode builds on the recent carbohydrate blog series and connects to the ongoing discussion about the 2025 to 2030 Dietary Guidelines. It also sets the stage for upcoming episodes that will explore carbohydrates in greater depth.

If you have ever wondered what carbohydrates actually are and why they matter, this episode provides context without oversimplifying the science.
