    print("This macro calculator allows you to calculate the next things: \n * Basal metabolism \n   * How much exercise you do \n * Macros on deficit/surplus")
    print("Also, \n 1. What are macros: the term “macros” is short for MACRONUTRIENTS in the context of nutrition. Macronutrients are the energy-giving components of food that fuels our body. They include carbohydrates, protein, and fat; this is where your dietary calories come from. \n 2. Why is important to count them: whether you want to lose weight, or gain muscles, counting macros helps you to track if your diet suits your needs. \n 3. Is this calculator precise?: nope! any of the calculators out there are not precise either. This are just aproximations to what macros you should eat. \n 4. FINAL ADVICE, tracking macros can be a nightmare, I recommend the use of \"Fitatu\" to track them!")
