I haven't ever experimented with IF. What is the basic gist of it? My plan was mainly just to cut saturated fats way back, (for the heart benefits, as well as caloric restriction) and just slowly cut down on a lowfat diet. But IF might be perfect for me, if I implement it well enough. Any thoughts on how to do it?
Oh yeah, for training, I plan on doing what I did this last cycle, 2 weeks of 10s, 2 weeks of 8s, then 2 weeks of 5s. Slightly heavier than vanilla, great for cutting.
Sounds like a good plan.
IF as per how most people run it is really just condensing your eating window to ~8-9 hours. Why would you do that?
1) The amount of meals per day doesn't really seem to matter, all else constant, i.e. if the carbs/fat/protein/total calories end up the same either way
2) There are probably satiety benefits to IF
For #2, a typical IF setup would be like this, assuming a 9-5 type work day. Last meal of the night at ~8-9 pm. Don't eat again until lunch the next day (12 pm). You can have coffee and even stuff like sugar free gum, but you don't start eating until ~12, and continue that for ~8-9 hours. Obviously the specific hours don't really matter, and I actually prefer a ~9 hour eating window personally, but that's the gist. 3 meals in that time works well, and given that you're dividing your entire day's calories into 3 meals, they wind up much larger meals than what you'd get on the typical 5-6 meals a day plan. The logic is that once you start eating for the day, you have effectively primed your brain/body to "expect" food. By delaying the first meal, you surprisingly don't wind up very hungry, and can retrain yourself to get hungry later in the day. Then by the time you start eating, you get to have large, satisfying meals instead of a bunch of little lame meals.
E.g. on a 2100 calories per day type diet, I'd eat 3, 700 calorie meals. That could be something like 8 oz of lean meat, an astronomical amount of vegetables, and then a ****load of fruit. If you divided that into 6 meals like bodybuilding conventional wisdom, you'd wind up with little lame 350 calorie meals. As you might infer, the former is a lot more fun, and despite dieting, you still get to have the feeling of fullness with your meals.
You can add additional logic to that (i.e. having a slightly disproportionate amount of your calories in the post-workout meal, higher carbs on training days and lower on non-training days), but it's really just about shortening the feeding window to give you some appetite advantages, imo. Which, in that sense, it works rather well. For reasons unclear the fasts also seem very useful for purging excess water weight, i.e. you walk around looking/feeling leaner than usual, at least in my experience.
