Hi, I have only just joined the forum and have a bit of a problem. I have been doing swimming for 3 weeks and running once a week. This week, I started watching my diet, not starving but eating healthily and not snacking. I bought a scale on Tuesday and I have weighed myself for 2 days...first day I had lost 700 grams and second day 500 grams. I got a bit startled by it because it seems too much, yet, I am not starving and swimming only 45 minutes a day and also doing some walking. Has anyone else had that in the beginning? I weighed 76,2 this morning, I am 168cm tall.
