> What specifically are you saying needs to be avoided btw?
Carbs, all of them, as much as you can.
Gotta think on the lines of what did human bodies evolve to process and use. Since sugar sources weren't always available, our bodies make all the glucose we need to live. We don't need sugar or carbs at all. Sure our body's do like them because it's easier for our bodies to process carbs to glucose than to make it from fats and other amino acids. This means our brain signals to eat more of the sugary stuff because its "free" energy.
> Are you suggesting people eat pure meat and lettuce and eggs for 6-8 weeks?
Kinda. It's scary yes, but as your body switches over to eating less carbs, it has to work harder to convert non carbs into things it can use. This levels out your blood sugar levels which in turn makes you less hungry.
> It would be so much more helpful to give some examples of sample diets people could actually follow.
My diet when I'm in the zone so to speak (Keto + intermittent fasting), looks like the following.
First meal around 1pm. Salad - a store bought green mix, might have a little carrot with it, various lettuce (not iceberg or just romaine), I might throw in an egg, a serving of a protein (anything from steak, lunch meat, tuna or salmon), some cheese, maybe something salty (olives or peppers) and some kind of non-sugary dressing (ranch, blue cheese, oil and vinegar), water or unsweet tea.
About 3pm - 5pm is a mixed bag and might be a snack or meal, and depends on hunger levels. This can be some nuts (almonds typically), cheese, lunch meat, protein shake, or just left overs.
7-8pm I'll have dinner. Bunless burgers are common, or just some source of protein and a veggie side. I like chicken, beef, pork, fish. You can make all kinds of stuff with them. Bake it, grill it, fry it (without breading). Meatloaf is good. Lots of good recipe sites, maybe you like tacos, so you can have them with low carb tortillas. Asian dishes work out too, as long as you modify them. Cauliflower can be subbed for rice.
8-9pm I'm likely to have another snack.
9pm-1pm - Water. I'll eat if my blood sugar levels demand it. But on a typical day, I avoid anything that needs to be digested.
