I am gaining weight. It is 69kg now. How can I lose it?

Lose it Health Wise. I just participated in the wellness challenge in the hamptons, a free program that promotes healthy and wise choices, based on the books, eat to lilve (dr. Fuhrman) and the engine 2 diet (rip esselstyn). Unprocessed fruits and vegetables and walking allowed up to feel happy, energetic, and drop our weights, cholesterol/triglyceride levels and also our blood sugars. I lost over 15 lbs. In 7 weeks.
Weight Loss. The best treatment for weight loss is diet, exercise and attitude. The most important is attitude. You need to have the desire to alter your current diet and exercise pattern. Basically, move more and eat less!
