The entire world eats 3 meals a day. Even if you eat 6 meals a day you can easily lose weight. It’s about the contents of the meal, not the frequency.
Eating three meals a day is a very very very recent thing if you account for human history, or even modern human history
Yea I can down a familiy pizza if its all I eat for the day.
Also, the rise of zero/light drinks have actually helped.
