Hi all, starting slimming world (again) on Tuesday. Just curious, why can some people eat what they want and others can't. My neice is 10 months younger than me and she says that she eats cake everyday, if I even look at cake I put on weight! She's about 10 stone and I am 17st and we are the same height (she's even got 3 kids!). Do you think it's just genetics? I think I'm just having a down day but it makes me really unhappy when I see other people eating what they want and not putting on any weight, I just don't get it. Sorry if I sound depressed, maybe I am , just want to hear your thoughts.
