Hello James!
I thought slimming centre are more concern about weight loss too but for mine, the consultants told me not to worry if I put on weight cos it might be muscle gain.. true enough, when I go for review everytime, my body fats and inches will reduced but I gain muscles instead their intention is to let me gain muscles, get rid of body fats and the most impt thing is I look healthier and more energetic now.. so now I do believe not all slimming centres are bogus
