You cannot eat and absorb all necessary nutrients in 2 or 3 meals. It is much better to divide them in 4-5 meals where your body can digest and use the various nutrients.

Without even talking about vitamins, fiber or healthy fats, let's take protein as an example as testosterone was the topic: Your body's protein absorption has a limit (it isn't not very straightforward and linear, and depends on the type of protein). How much protein can you gulp in 2 or 3 sitting to make a healthy man "keep his muscle mass" and how much of it will be absorbed vs. stored or excreted? What if you're building muscle? What if you're regularly training?

What part of our evolution favors fasting? Snacking doesn't mean you eat every 30 mins. If you're awake 16-17 hours a day, you can easily divide your 4-5 meals with 3-4 hours apart. This keeps your metabolism going. Especially if you're exercising.
