Not in my opinion. If you have no choice, you are forced to have two meals a day, I can understand that but it's not healthy.
The healthiest to have five meals a day, three main meals (breakfast, lunch and dinner) and two snacks. It's better for your stomach to eat less and more often.
It helps to plan ahead, buy healthy ingredients and prepare your food yourself, that way you know what and how much you eat. Deciding on the go can lead to unhealthy decisions which can have consequences.
However, Max Lowery a former stockbroker, who later became a personal trainer, says having two meals a day is healthy, "you can retrain your body to become "fat adapted," meaning you burn stored body fat for energy, rather than being dependent on sugars from food. " (source: https://www.businessinsider.com/the-2-meal-day-diet-plan-max-2017-7). According to his theory, you can have more energy and also lose weight.
I'm used to having at least three meals a day but I prefer five. I don't like that "full" sensation in my stomach that occurs when I'm eating too much. Eating too much can make me sleepy, loose energy. My preference is light meals more often, spaced out. Five it works for me.
If nutrition is sufficient, it is not a problem. every food we consume has certain nutritional value. if you eat as much as possible but do not have nutritional content. I think being unwell.
