Every diet is individual. No one diet works for everyone, and there is no specific diet that works for every runner. If someone is starting a running plan, they may want to make some tweaks to their existing diet. They can focus on consuming an adequate amount of carbohydrates, eating enough before and after workouts, and filling their plate with various fruits and vegetables. A person’s caloric needs will vary depending on their weight, height, and energy expenditure. Runners should be aware that they will need to increase their calories to recover and perform properly when they increase their mileage. Micronutrients are vitamins and minerals, and the body uses them in many crucial life-sustaining biological processes. Eating a balanced diet full of fruits and vegetables will usually provide a person with a healthy level of micronutrients. They may be particularly important for athletes. Doing a lot of training can put the body in an inflammatory, sometimes immunocompromised, state. This makes it easier to get sick and feel run down. A 2000 article points out that in addition to eating enough calories, consuming adequate micronutrients can minimize source inflammatory effects of training. While most people can get their micronutrients from food, some people with restricted diets may be lacking. Research from 2019 suggested that people who follow vegetarian or vegan diets may need to supplement with vitamin B12, vitamin D, and iron to replenish the nutrients lost through sweating while running. Eating enough protein, carbohydrates, and fats will keep runners fueled and healthy. While individual needs will vary, many runners can follow some basic guidelines when planning their diet. Carbohydrates are a fundamental component of a runners’ diet. They are the body’s most accessible form of energy, as they break down easily during exercise. A 2008 study of elite runners showed that most participants consumed 50–70%Trusted Source of their daily calories from carbs. Those who trained at higher intensities and ran longer distances needed more carbs. While most amateur runners are not running the 100 miles or more per week that elites do, they should still focus on eating enough carbs. Eating too few can cause sluggish runs, poor recovery, injury, and overtraining. Nutritious sources of carbohydrates contain fiber, vitamins, and minerals. Some popular carbohydrate sources among runners. Protein builds and repairs bones, tissues, and hardworking muscles. This means eating enough protein is essential for muscle recovery after workouts. One small 2017 study of elite runners found that participants experienced fewer injuries and had better endurance when they supplemented their diets with whey protein. However, people who run recreationally may get all the protein they need from their diet. It might be helpful to prioritize consuming a protein-rich snack or meal after a run. Research from 2008 suggests that consuming a source of carbs and protein after a workout promotes glycogen storage, which can aid muscle recovery. Fats are an essential part of a balanced diet and are particularly important for nerve function. A 2018 review noted that athletes, including those who run or swim, tend not to consume enough fat in their diets. Additionally, endurance athletes may notice their performance improves when they include more healthy fats in their diet.
