1. What is this Q&A?
This is a collection of Questions and Answers. Each top level header forms a category, within which are lower level headers answering questions. If a question has layers and depth, sub-headers will ask new questions and answer them.
2. Health and Nutrition
2.1. Q: What is the Mass Balance Model?
A: The Mass Balance Model (MBM) is a theory for explaining weight gain and loss, particularly that of fat mass. It is a replacement for the Energy Balance Theory (EBT), sometimes known by the acronym CICO—which stands for Calories In, Calories Out.
The MBM posits that bodyweight is managed by the Law of Conservation of Mass, not the Law of Conservation of Energy. It has been shown to better represent expected weight gain/loss calculations as compared with real clinical data.

2.2. Q: Do we need fiber for digestive health?
A: No. In fact, fiber may be deleterious to digestive health. There is little to no evidence that it helps with the things that people like to say it helps with. It may also be detrimental to female reproductive functions. If you are having trouble with motility, fat is the answer.

2.3. Q: How does satiety work?
A: In short, Reactive Oxygen Species (ROS) function as signals which cells emit when they produce energy. The more energy produced, the more ROS are emitted. The brain determines satiety from multiple factors but the most important one seems to be how much energy, and thus ROS is being produced.

2.3.1. TODO Q: Why do people eat too much? How does satiety break?
A:
2.4. Q: Do carbs help my workout?
A: They certainly can, if you are reaching exhaustion. Even for those in ketosis, a small amount of supplemented glucose can reduce exhaustion. If you are an endurance athlete, as little as 10 g of glucose taken once every two hours can be beneficial. This is because the symptom of exhaustion is not due to muscle fatigue but due to the muscle sucking up too much glucose from the bloodstream and starving the brain.

2.5. Q: What is the Cube Rule of Food?
A: The Cube Rule of Food actually has nothing to do with nutrition. It is a way of determining what category a food falls into, finally solving the debate over whether or not a hotdog is a sandwich.
