So I am using the same weight loss regime I successfully used 5 years ago to try to lose 15kg. Its only been 2 weeks but I have lose almost 3kg but my body fat has gone from 24.9 to 25.3 (the wrong way). I have not significantly changed what I eat, just how much I eat. In my successful weight loss 5 years ago my body fat decreased progressively with my weight but I am 5 years older now (and approaching 60). My weight loss program is walking and jogging with the aim to get back to comfortably jogging 5k in under 30 minutes 3-4 days a week.
