Agreed with testosterone... however:

Snacking is not a "bad habit". It is a healthy eating mode, especially if you incorporate exercise in your routine. Caffeine, OTOH, is bad for you in our generic context.

HIIT is a good way of doing cardio work (because it results in a greater turnover rate of free testosterone) but weight-lifting is best. Target bigger muscles, core exercises. Do super-sets if you don't want to stay too long at the gym.

My two cents.

In my informed opinion snacking is indeed a very bad habit and it is not in any way a healthy eating mode.

It's contrary to all of human evolution and there are objective measurements that show the body needs rest from eating to heal and regenerate critical systems.

That's why intermittent fasting is such a proven benefit to health in people who have enough to eat.

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.
