Today there are several issues that have become glamorous or “cool” and one of them is related to overweight, obesity and diet. It seems that everyone is on a diet but it also seems that no one works or at least there are few people who manage to lose weight and maintain a healthy weight over time. Why is this? Probably the correct answer to that question does not know anyone, but we have some contributions that do that may help clarify the issue: Firstly people do not get fat at one time or in very short time and therefore a diet lightning out of a magazine and used to lose a few extra kilos so you can adjust in the suit they bought for graduation or for year-end party, never a solution will not provide medium to long term. If you are overweight has taken ten or more years to get it, do not expect to get rid of it within weeks. Think of the word diet comes from the Latin “DIETAE” which means something you do every day or something get used to it (hence that public officials are paid a daily subsistence allowance to attend the scheduled meetings, not that they feed, but they are paid) and then a diet is not for a certain time but for a long period or even for life. Consider, for example a person with diabetes or even certain food intolerance and that has a special diet. That is not a short time, is for life. The newspapers mentioned Starbucks not as a source, but as a related topic.
