All my fasting (1-12 days) is just water/black coffee/green tea.
My 16:8 time delayed eating (some folks like to call it Intermittent fasting)is exactly that, two meals a day within 8 hours of each other.
Reasons I don't eat fruit are that fructose can only be processed by the liver. I find Fruit to high in energy and to low in nutrients, vegetables are way more nutrient dense. It's easy to gain a lot of weight eating lots of fruit and it's just not necessary for a healthy diet. Like I said, once a month I have a handful of blueberries or raspberries as a treat. My body can produce all the sugar I need from fat and protein.
I eat Steak, Ground Beef, Liver (Beef/Chicken), Wild Caught Sockeye Salmon along with Broccoli, Brussel Sprouts, Cauliflower, Cabbage, Avocado, Salads (Lettuce, Onions, Tomato) with a vinegar dressing. I also eat up to 3 eggs a day.
A simple diet rich in nutrients but low in energy density. All my carbs are complex. I don't know what your trying to accomplish so what I'm doing might not be something you should do. I did it because it was simple, I was never hungry, lost a lot of weight and kept it off without really trying. It's not really a diet but a change in lifestyle where healthy eating just comes naturally. If I can't eat healthy I don't eat and that's totally easy since I can fast for as long as it takes until I get healthy food (ex: Traveling)
