Keep up electrolytes. The major electrolytes in our bodies are sodium, potassium and magnesium. Because a low carb diet (especially a keto diet!) reduces the amount of water you store, this can flush out electrolytes and make you feel sick (called “keto flu”). This is temporary, but you can avoid or eliminate it by salting your food liberally, drinking broth (especially bone broth), and eating pickled vegetables. Some people also choose to take supplements for electrolytes, but it’s best to first consult a doctor that understands and supports keto/low carb lifestyles.
Healthy fats & oils are back in too: Eating fat does not automatically clog the blood vessels in the way that poring oil down the drain will eventually block the drain. You make your own cholesterol and lipids and are more likely to increase your levels of the more damaging Very Low Density Lipoprotein (VLD), which is made in the liver when you eat a high carbohydrate diet.
my children regularly make themselves smoothies, bacon (2 minutes in the microwave covered with kitchen paper), scrambled eggs with cheese in the microwave (mix 2 eggs, cheese, milk – 1 minute, stir, 30 seconds, stir, 30 seconds, stir). They used to moan and complain there are no cereals in the house, but they have learned to cook their own breakfasts and look for what ingredients we have rather than reach for a box of cornflakes
