I’m the opposite, I have multiple small meals a day, I can’t really sit and eat a large meal. I guess the Meal size for many would be considered a snack by many, but I eat little and often and it seems to work for me.
example.
morning, a couple of hand fulls of dried fruit, prunes, figs, mango, cranberries etc,
lunch, a couple of thin slice of meat, like chicken, beef or ham, with a couple of table spoons of veg or salad,
mid afternoon somethjng similar,
dinner, a small portion of whatever my family is having.
late evening, some more fruit,
prob a 1000-1200 cals a day, and is working for me, my energy is regulated, I have no desire to eat unhealthy food, I have no side effects, like nausea or feeling over full at any time, and everything I eat is low fat/carb really
I didn’t set out to do it, but understand in hindsight it’s recommended and it works for me.
