Weight loss

Ever tried losing weight? It is some serious commitment and work. I am here and want to lose a minimum of 8kg and maximum of 15kg and I do not want to go on any diet. Asides the fact that they are expensive, they are also restrictive. I love my chocolate biscuits, mousses and anything sweet. So confused on what to do and I do not want to gain anymore weight. Considering the fact that I'm also using an implant, the weight won't just budge. Anyone out there with ideas on how to lose weight and wont cost money. I'm open to all suggestions.
