Health & Fitness
Exercise, nutrition and rest, without the marketing.
Health information is unusually crowded with confident claims sold by people with something to sell, which makes the well-established basics worth knowing precisely. This category covers what different kinds of exercise do to the body, the roles of the main nutrient groups, and why sleep and recovery matter as much as training. It sticks to broadly settled consensus and is general information rather than personal advice, since individual circumstances vary and a doctor is the right source for those. The explanations describe the mechanism, which also makes the marketing easier to see through.
