Interesting publication, the phenomenon to which you refer is very common in family groups. Each person brings his or her culture and eating habits, what we could define as eating style. When a family is structured, different styles are combined and mixed.
A priori we could consider that there is enough similarity between the styles, but most of the time they are only appearances, in reality, there are differences in the preference of the food to consume, ways of preparation, hours of consumption, quantity of portions, etc.
I believe that when a family is structured, a style of feeding that family is born, which should be the product of negotiation and agreement, where everyone should feel satiated and pleased. Feeding is an act of self-love and at the same time of their own. The North will always be the promotion and practice of healthy eating styles.
However, there are conditions in which it is necessary to introduce particularities. For example, when a family member has a health condition, which justifies variations in their diet. Likewise, children have unique nutritional requirements that need to be considered in the family's eating style.
They should talk as a family, share tastes and preferences, and as soon as possible give rise to a family eating style, with schedules, calculation of portions, foods to be consumed, etc. Perhaps a specialist in the nutritional area can be of help and guidance, where, as a family, they can express their interests. Exercise and the physical activity it implies is life and should always be present and be part of a healthy lifestyle in every family group.
