Given up pasta, rice, and bread wasn't that big of a deal. Potatoes on the other hand.
It is a lot of work with a fulltime job, and a non-supportive McDonald's eating spouse; but I feel great. Just fixed blackened tilapia and fried eggplant and it filled me right up. Still a challenge to go 12 hours between meals. I don't buy all the fat thing with it (I am still zealous about removing visible fat from steak and no chicken skin), but I am using an incredible amout of olive oil and butter (I actually cut back on recipes). Love the avacodo a day.
One thing about eating well is that it can be expensive (versus my old standby cheese, salsa, and baked potato). The basis for keto is zucchini, summer squash, broccoli, and cauliflower; and that is a whole lot more expensive than potatoes. My wife has said a few things about the cost, but it is not like I eat a McD breakfast sandwich a day with a follow up to Culvers, Pablos, or another fast food place in the evening. My wife must get at least 60% of her nutritional calories from fast food.
