For a low-carb Belgian diet, focus on lean proteins like poultry and fish, incorporate non-starchy vegetables, and enjoy moderate amounts of high-quality cheese. Choose unsweetened chocolates and coffee, and replace traditional waffles with a low-carb alternative using almond or coconut flour. Additionally, prioritize foods rich in healthy fats, like avocados and olive oil, while minimizing intake of high-carb items like potatoes and sugary treats.
