I'd say tough guys usually. Very disciplined and tough to break kind of people will big will and commitment.
I'm not a huge fan of eating many meals, I'm more into intermittent fasting, though. However, I do think that people are to blame for their little knowledge of basically anything they do. Now with corona you just see that people would like a Matrix pill that solves everything without them doing anything. Same goes for losing weight as you see people swallow pills but keep eating fast food and all shit there is. Majority fills themselves with tons of carbs, they lack protein and general knowledge what they do with their body with the crap they eat. They stuff themselves with food and then wonder why they have lack of will or why they feel sleepy. Duh. I'm not saying it'd solve corona but it surely helps if you keep your body fit and eat healthy. Those who count calories and do that are usually those who know what they eat even by being obsessed by it. But no, people have horrible diet and once they get sick they stuff themselves with medicine eventhough body is fragile. I think people are really bad when it comes to helping themselves.
