I mean, we're only talking about Adam here... and not referring to anyone doing proper fasting, who are under the care of a physician, and / or whatever.

Besides, are we to believe that ginormous gut he's been sporting is ONLY from eating one time a day? Like
@VloggerCritic even inferred re: his coffee. If he's at Starbucks in the a.m. and happens to get a loaded coffee with lots of crap in it (e.g., sugars, creams, added flavors, etc.), that could be the equivalent in calories of a meal itself.
Me think he's fibbing here or there in what he does off camera.
