The plant-based diet focuses on 90% fruits, vegetables, whole grains, healthy fats, and clean protein, and reduced intake of animal by-products. You can go full vegetarian/vegan, but ensure you're getting the good amounts of vitamins, minerals, and protein. The result is a nutrient-dense and protein-rich diet that fuels peak performance. I personally have found that it has helps my mood, energy, and athletic performance. Three rules that I typically follow:
Consume lots of fruits and vegetables. You want to focus on having a colourful variety so you can consume vitamins and minerals essential for health. Go organic if you can to avoid consuming pesticides.
Protein sources could include whole grains, eggs, tofu, and legumes. Legumes can include things like beans, chickpeas, and lentils. Try to stay away from red meat, poultry, and pork.
Focus on whole, natural foods. Limit your intake of refined sugar, processed foods, and fried foods.
Also try to reduce your intake of alcohol (beer, wine, and hard liqueurs), but it is definitely okay to treat yourself every once in a while! If you want more details about specific foods to buy on a plant-based diet, check out my plant-based grocery list.
