Sorry, no lentils.
And yes, no need to eat any meal if you're not hungry.
We were fed a pack of lies about the importance of "3 meals a day", eating multiple mini meals, etc.
Breakfast is whatever first meal you eat during the day, whether it's at 9am or 2 in the afternoon.
More or less I settle into eating 2 meals a day (just like my grandmother did all her life) and maybe in the evening a glass of unsweetened coconut milk with some cream mixed in, with some monkfruit sweetner and vanilla extract. Or strawberry extract.
See, that's the problem. Keto is a fad right now, and food manufacturers have jumped on the band wagon.
Basically they are taking an extremely simple way of eating and over complicating it.
While the biochemistry behind it is facinating, the actual living it day to day is stupidly simple.
I do well on 25 to 28 net carbs a day, which is total grams of carbs minus grams of fiber.
Typical first meal is 3 eggs, bacon or sausage, butter, cheese, avocado, tomato, mushroom, a little onion
Later, steak, fish, poultry, sausage, whatever strikes my fancy, and some more veg.
Snack if I want can be salami, olives and cheese.
Or, nachos made with pork rinds, cheese, sour cream and salsa.
