Nutrition
Nutrition is very important for any sort of active lifestyle, including running.
Nutrition needs will vary widely based on your running goals and training status, but generally it’s recommended to remove as many processed sugars and “bad fats” as possible. I’ve had success with a consistent sustainable diet high in vegetables, proteins, good fats, and plenty of water.
Runners World suggests these things to fuel your miles.
Nutrition and diets change significantly for the “carbo load” leading into a long race (such as a marathon or half marathon). Refer to the training plans regarding the change in diet (increase in volume of carbs and fluids / water).
Generally, if some “get healthy (or lose weight or get fit) quickly” magic pill or powder or substance or program sounds too good to be true, it most likely is too good to be true. I tend to just ignore these, and instead rely on good natural nutrition options from high nutrition, non-processed foods, as part of a diet one can sustain over extended periods of time.
