You don’t actually need to eat a nutritious diet to have ab definition - it’s just low body fat, like Emily Canham who also doesn’t eat healthily. I do think she’s probably editing them to enhance them though as it seems like they’ve only really appeared since she started wanging on about her PT course (if she’s even still doing it since the ad ended)I think the photo of her “abs” is heavily edited. Ab muscles will only usually protrude if someone follows a nutritional diet, no matter how many crunches they do. She scoffs anything and everything. She’s also heavily altered the shadows and highlights in that photo to make her appear more defined - and left herself bright orange in the process.
