Tess is trapped by her brand. No doubt the lard prison of which you speak is already seriously impacting her daily comfort if not health. If you recall she flirted with exercise via "work outs" with that slumming celebrity trainer of hers but couldn't bring herself to say she wanted lose weight only that she wanted to get "stronger" in the vaguest sense. Who knows how long that charade lasted beyond a couple insta posts. She probably realizes this as much as anyone which is why she sank into calorie inhaling depression and comes back worse off than before.
