  1. Understanding the Complexity of Calories in, Calories Out: The concept of calories in, calories out is often seen as simplistic, but it is actually quite complicated. A calorie is a unit of energy, specifically heat, related to the potential chemical energy in the bonds of the macronutrients in food. Digesting, assimilating, and metabolizing nutrients allows the creation of energy.

  2. Fiber (Prebiotics) Is Better Than Probiotics: More diversity in the gut, consumption of fiber, and supplemented prebiotics are shown to be better for a healthier gut than probiotics. Probiotics are typically not concentrated enough to colonize the gut, and even if they do, without proper fiber, they starve. Research suggests that consuming fiber, a prebiotic, is a more effective method for promoting gut health.
