Childhood obesity and obesity in adults - the difference

Is their a difference in obesity beginning in childhood and adulthood.

Nowadays with multiple foods easily available, children and also adults hardly like to eat home food. The dietary habits have shifted from eating fruits, vegetables, whole grain preparation, milk and products to caloric dense (either loaded with fat or sugar) highly processed foods and drinks which just have calories and very less nutrition in proportion to the same.

The fat cell theory is one of the mechanisms that explain obesity in children due to overfeeding in early years of life. The fat cells are distributed throughout the body. The depot expands either by increasing the size of fat cell or by increasing their number. According to the theory the percentage of body fat is determined by the number of fat cells which is either influenced by genetic inheritance or eating habits.

The size of fat cells gradually increases if the energy balance is positive. If the energy or caloric intake continues to be high, cell number begins to increase. Once fat cells increase their number seems to be fixed and they cannot be lost even if weight is lost. In general, cells proliferate most rapidly from birth to 2 years of age and during the late childhood and puberty.

During childhood, chronic overfeeding leads to increased number of these fat cells. Fat cells once formed cannot be decreased. In the long run if positive energy balance (you take in more calories than you expend)continues, fat cells would keep increasing in size further leading to obesity in adulthood as well. Thus, good eating habits during childhood are of great importance.

This is the difference in  from obesity beginning in adulthood and childhood.  In adulthood, obesity begins due to increase in the fat cell size and in childhood the number of fat cells also increase.

So please pay attention to what your kids eat, they may not understand now but  will definitely thank you in future for developing healthy eating habits.
