Eat to live, don’t live to eat – that is the watch phrase these days. It’s not the done thing to be out of shape today, not when all and sundry are becoming increasingly health and fitness conscious. Good health is the result of the right mix of exercise and diet. So it follows that there is a demand for fitness trainers and dieticians.

Not everyone loses weight and gains health by following the same diet. In this situation, it is certainly not a case of “what’s good for the goose is good for the gander”. Instead, the dietician has to follow the policy, “one man’s meat is another’s poison”, and fashion diets in an individual manner for all his/her patients. 

You can earn a dietician’s certificate online, even specializing in designing diets for various categories of people, from the very ill to those who just need to change their eating habits.
