It’s best to start from a baseline and adjust it to your individual needs. For someone new to healthy eating, focus on getting the majority of your calories from whole foods and avoiding processed and ultra-processed foods like fake meat, sugar-sweetened sodas, packaged baked goods, and boxed foods. Eat a variety of colorful fruits and vegetables to vary your micronutrient intake. Always have healthy food on hand, meal prep your own food, and rotate your favorite recipes. Avoid sugar as much as possible, especially added sugars. Learn more about how to go sugar-free. You might also like my post with suggestions for how to eat clean.
