What do you mean how's that work??
You eat once a day, if you eat nutritiously dense food you generally don't get hungry that often. If you eat processed garbage then you tend to get hungry all the time as your body is craving nutrition, however if you are feeding it nutrient devoid calories you will be forever hungry and have cravings.
Calories and nutrition are two different things.
You can eat 5000 calories a day and get almost zero nutrition or you could eat 1000 calories a day and get all the nutrition you require. The first person will still be hungry and have cravings while the second will be satisfied till his body requires further nutrition. That's why nutrient dense foods leave you satisfied and full for much longer.
Humans never ate three of five meals a day, or never had snacks, it's a new phenomenon created by food companies who want to sell you all this unnecessary stuff, my daughter is 16 and she naturally eats one meal a day, usually dinner, it's actually how we are meant to eat. It's not set in stone, If I get hungry (I mean hungry, not bored feeling like I could eat something) then I will eat something.
It actually is, but I m not training for strength at my age, I am training for health and well being. The strongest people on the planet are not necessarily healthy, quite the opposite actually they are walking a tight rope of stroke and heart attack.
I don't think Baz can do a lot if he still lives in opposite world. It seems according to him that the best strength programs make him weaker and eating copious amounts of pizza makes him lean AF.
