TRA is safe for all above 12 years of age. Don't worry about the process as the consultant will come by and visit you to keep track of what you eat and monitor your weight. At the same time, you can ask questions and give some feedback to how you feel throughout that session. It is always better to start early so you can get your metabolism working for you =) I am glad my consultant constantly came by to monitor my weight. Although i was slightly annoyed by the fact that I had to meet him so often, I am elated to see the improvements. Overall, my skin got better, I no longer have a problem clearing my system daily, and most importantly, I kept the weight off. My dad who took it under the same monitor of my consultant also managed to lose 8kg in three months (He had a beer belly). Now, not only does he feel more energized, he is also off the medications that he had been taking for eight years - high blood, high cholesterol, diabetic. In fact, my main objective for me to let my dad meet my consultant wasn't so much on making him lose weight, but to get him to be healthy again. I thank all great things around me to have my dad in the pink of health, and I hope you can give this a try as I have convinced myself. (I have never really believed in this until what they did to my dad) - his latest medical report proved it.
