It may seem tedious to eat the same types of food everyday but you are probably already doing it now. Just list the food you eat on a regular basis. If you are like most people, you scarcely have 20 items on this list.
A macronutrient diet does not have to be boring. I consider the meals in my macronutrient diet my core meals that I can embellish with culinary wizardry. I just add homemade sauces or substitute pasta with bread in my diet.
And, I don’t confine myself to the base. If I want to have a mocha and bagel for breakfast, that’s what I will have. Then I’ll eat the rest of my meals as planned. If I prefer to eat a sandwich at a diner for lunch, I do that.
The point is that I am comfortable with my personally designed macronutrient diet and my caloric needs and know what I need to do to maintain my ideal weight. Likewise, I know the consequences of my eating decisions over the long term. So, I have my indulgences while adhering to my macronutrient diet core.
