Healthy cooking simply means low carbs and low fat. So, no deep frying, no skin on your chicken, trim fat off chops and steaks, eat veggies, fruit, seeds and nuts. Have greens every day, drink lots of water and follow the national food pyramid. Not a mystery, just watch what you eat.
Healthy cooking is for people who have serious issues with food and generally tend to be obsessive about body image, sickness and death.
So the name of the game is to be able to separate what is in fact actually unhealthy and what the “we hate good food ” Nazis consider to be unhealthy
