I want to get rid of 20 kilograms. At this moment I weight 102 kilograms and I am 183 centimeters tall. As you can see, my weight is a bit overwhelming. It indeed overwhelms me and I do not want that. I want to lose this weight because it bothers me a lot. I do not care what other people think about me. I do not care when they call me names. All I care about is how I feel and I want to feel better. I want to feel alive all over again. I was not always that huge. Quite frankly, I used to be lean and rather well-built. However, after my father passed away I got depressed. I found my solace in food, which obviously was not the best choice. Now I have to struggle with it. Therefore, I seek information on how can i lose weight. It does not matter what I have to do because I will do it anyway. Nevertheless, at this moment I do not know how can i lose weight and it bothers me a lot. Losing weight is not that simple at all. You need to have certain knowledge to get it done the right way. I do not want to starve myself to death because it makes no sense whatsoever.
