Relying on the results of the first week and presenting them as some misleading charts, are not the best way to encourage people to buy these desks. It is obvious this is an advertising article. In next few months your body will consider this as a habit, adapt to the situation, hit a plateau, stop burning extra calories and you start gaining weight despite the fact you are walking everyday (The postman syndrome !!). unless you change the intensity of your exercise, which is not possible at all while you are working. I am sure there are plenty of researches on postman syndrome that you could include.
So why don't you just talk about the actual benefits for body, and skip the weight loss part?
