If you are dieters, you will probably hear of Dr Robert Atkins? low-carb diet, Dr Peter D'Adamo's blood-type diet, Dr Barry Sears? Zone Diet, and Dr Arthur Agatston's South Beach Diet.

Dr Rami Cohen is less well-known but his weight-loss plan has been helping people reduced kilos in countries like South Africa, Australia, Britain, the Netherlands and the United States for more than 20 years.

Anyone who intends to go on diet will need to go for a blood test. Dr Cohen will personally analyze the blood test results and he will then come up with a specific eating plan which balances proteins and carbohydrates. The diet is not based solely on counting calories, but on food types, quantities and combinations. The aim of the plan is to correct the hormonal imbalance that is believed to prevent weight loss.

The three hormones linked to obesity, as identified by Dr Cohen, are insulin, serotonin, and the human growth hormone. According to him, obesity is a disease and has little or nothing to do with a lack of self-discipline. His idea is that most people with weight problems do not have the right balance of these hormones, so no matter how hard they diet or exercise, they will find it hard to lose the kilo. The program can help most people lose weight from 7 kg to 15 kg in the first month of the program.

Some health-care professionals tend to disagree on this method of losing weight. Some do not approve the rapid weight loss. Medically, it is better to lose weight gradually, about 2 kg per month, as dramatic weight loss is not sustainable and the weight tends to go back on soon after. Others remain skeptical of the overall approach. Though there are hormonal imbalances such as deficiencies in growth and thyroid hormones that predispose one to gaining excessive weight, these conditions would rather need medical intervention.

Nonetheless, the Cohen program perhaps would offer help for those weak-willed. Monthly blood tests will show if they have deviated from the plan, and counseling is available whenever needed.

Personally, I still believe that a healthy and balance diet coupled with moderate exercise and certain degree of self discipline is still the key to keep you a healthy weight with a happy heart.
