What's with the conversation with herself she's having in that caption? "I'm so sorry I let you down Kirsty"
she's so weird. Also it's not the method of losing weight that's the issue, if she can't stick to a calorie deficit in order to lose weight what makes her think she'll stick to SW?? The amount of calories she'll be able to have and still be in a deficit, at her size, should be more than enough for her to make a good go of it and she hasn't, so what changes just because you give foods imaginary labels and values? If you're overeating, you're overeating
