Well firstly you have to remember that eating this way, if you get the balance right brings enormous satiety levels, which in turn means you tend to eat less and eat less often. And for me this personally has to be the biggest benefit of all because if you know my history, you'll know I've experienced what I now know to be a whole range of diet/lifestyle metabolic issues, one of the symptoms for me being constant hunger.
Anyway the point I am making is that it's now not unusual for me to skip the odd meal as I now only eat when properly hungry. Also food has become more clinical, kind of logical, I eat some combinations that some might be aghast at but your relationship with food really starts to change when you eat like this, it's like your brain subconsciously orders you eat certain foods more for the nutritional content rather than their aesthetic appeal. For example I have just had 3 Eggs Fried in Butter, half an Avocado and a handful of Walnuts for brunch.
As for foods, I try to get butter into my diet whenever I can, so I cook in it a lot, I'll eat Eggs and Bacon for breakfast, or an omelet with spinach, cheese, bacon, mushrooms and a small tomato, if I am in a rush then I'll often eat and Avocado and/or nuts. My Step-Daughter and her Husband switched to this way of eating after staying with us, they both work and are out of the house early in the morning (at the rush) so they oftens have Smoothies made with Spinach and Frozen Berries for convenience. Lunch often depends once again on how hungry I am and what I ate or did not eat for breakfast but often I'll eat an Oily Fish something like Smoked Mackerel, often with eggs if I can, sometime I'll eat a whole fresh coconut when I can get them. Dinner is often chicken with the skin on, steak, high meat content sausages or burgers etc served with a mixed green salad, olives, spinach, avocado again. I make my own Coleslaw with homemade Full Fat Mayo. Or something like liver and bacon with Cauliflower or Sweet Potato Mash. Or a Roast Dinner, I rarely eat roast potatoes though instead I'll have 2 roast Parsnips and some sweet potato/carrot mash. Or something like a curry or chilli with Cauliflower rice instead of conventional rice, or a Pasta Dish, with either Carrot or Courgette spaghetti/tagliatelle (we have a machine that makes the shapes but you can do it by hand). Sometimes I'll have some dark chocolate (High cocoa content 85% plus). I drink coffee until midday with double cream in it or Tea after midday with Full Fat Milk in it. Weekends I'll have the occasional whisky, straight and if I am throwing all caution to the wind a couple of pints of Guinness
There are lots of things you can eat, lots of resource and recipes online but It's basically about eating well, unprocessed, real food and keeping an eye on the sugar content, including natural sugar and starches from grains, potatoes, fruit etc in your eye
