Changing lifestyle or persuading someone else to do so is a difficult job.

Problems like obesity are growing with such a pace that it has become a major concern for the health departments to take an immediate action soon. But after practicing various approaches, they have discovered that it is linked to deeply-entrenched lifestyle choices and therefore is not easy to alter.

For giving it a hard punch, tougher policies are required. Soft policy "nudges" in no way can ever succeed to find a solution to it.

According to Lord Krebs, chairman of the House of Lords Science and Technology Committee and incoming president of the British Science Association, it is absolutely wrong to think if incentives and encouragement alone can help in changing the eating and other lifestyle habits of an individual.

There need to be strict regulations for marketing and advertising approaches.

When a child is introduced to sugary snacks in the off supermarket checkouts, he is not at blame to eat it in large quantity and that too regularly, it is the marketing companies who are at a fault for creating such attraction for these products.

It is something ‘totally inappropriate’.

To combat child obesity, the only way is to encourage healthy eating along with a regular exercise regime and this is possible by following strict marketing and advertising techniques.
