That is basically my point. That is probably about 800 calories of food right there. 2 heads of cauliflower is about 400 calories. Now if that meal fills you up, there is no chance you are going to not be full after eating 1 head of cauliflower. SO there is no chance someone is going to be eating 4 of them throughout the day, before he reaches dinner. So someone having trouble losing weight, upped their veggie intake. They would most likely start losing more weight since nothing is more satiating than those types of foods. However, all just an exercise in showing how satiating different foods are. Your current diet is far healthier than just eating 2 heads of cauliflower all day, sure you would lose more weight, but you would also be ridiculously malnourished lol.
The whole point of this discussion was to show. Lets say you were an individual who didn't get full off 2 eggs, 2 bacon, and a big pat of butter. Lets say you are someone with a larger appetite. maybe he needs 4 eggs to feel satiated, but in order to maintain his weight(like you are doing) he needs to only eat 2 eggs, 2 bacon, a big pat of butter, and a handful of nuts. What can he do? He can add 2 eggs, but that would mean he is eating 140extra calories per day multiply that by 7 and you have 980 extra calories per day. Most likely that guy is going to put on about a qaurter pound of weight per week until his TDEE increases 140 calories. Which may take him gaining 26lbs of weight to do so(This is not an exageration your TDEE goes up very slowly with your weight. I just pumped the numbers into a few TDEE calcs and that is what I came up with).
So what can he do instead? He could cut the pat of butter in half and eat 1 head of cauliflower along with his meal. He is still getting the optimal .4 grams of fat per lb of bodyweight per day. Still getting his needed protein. He won't gain a single pound(he may actually lose a bit since he is going to be getting a lot more fiber) And he is going to be a **** of a lot more full eating 2 eggs, small pat of butter, 2 bacon, and handful of nuts, with a head of cualiflower. When compared to 2 eggs, big pat of butter, 2 bacon, and handful of nuts.
