Trying to lose weight.

When i see someone that is thinner then me I get get self-conscious. And that motavates me to lose weight. So here is my plan to loose weight. I have an egg, corn and a cup of soybean milk for breakfast. A Little rice and some meat for lunch. Vegetables and fruits for dinner. I go to gym in the evening to run or walk fast for about one hour and take a yoga class. When I get home I do moxibostion after shower. I have done this for four days and I lost 0.5KG. It is not easy but I will try to keep going and hope can loose the weight.

The last thing I want to ask is how much should a girl who is 162cm weigh?
