How should people who are prone to catch a cold make a fitness plan?

I don't eat very well. My three meals are often casual in the morning, working at noon and eating a big meal at night. And usually greasy, fried, with pigments, chemical additives, food and sugar are not allowed to eat, irritants intake. All these will lead to the imbalance of adrenaline secretion, insomnia, inability to sleep in the morning or special fatigue after waking up, facial edema and fat loss at the waist, so what I do is to eat less sugar, eat less fried food and drink mineral water. Supplementing B vitamins, vitamin C, zinc, magnesium and other minerals requires these things to convert sugar in carbohydrates into energy, not fat. Usually eat carbohydrates that release energy slowly for three meals, such as most fruits, and eat fruits before meals every time.

The total amount of fruits and vegetables accounts for 50-70% of the total food. Most seed foods contain zinc and magnesium, and most fruits contain B vitamins and vitamin C.
