Intervention in socialization

Eating has become more of a social activity nowadays. We see that in everyday life, occasions, parties, and meetings involve food in one way or the other. Business matters are discussed over lunch or dinner between two parties, families get together over meals, friends meet in a restaurant, students are taught caring and sharing via making them share their lunch.

In such situations, people eat anything without considering its impact on health. Yes, you can consume a lot of calories but that does not mean eating unhealthy junk food and destroying the entire purpose of intermittent fasting.

Digestion Problems

If your medical condition is not very serious then you can consult your doctor and only start intermittent fasting if he/she allows.

In addition to this, problems related to menstruation, early menopause, and metabolism disruptions may occur.
