She is almost 6ft tall if not 6ft, she has to be carrying a lot of excess weight to be looking as big as she does and to get to a size 26, a 5ft 4 size 26 and a 6ft size 26 are very different weight wise. Wouldn’t surprise me at all if she has bariatric surgery because at this point I can’t see anything else working for her to shed the amount of weight she needs to lose in a time period where she doesn’t lose motivation. She could easily lose 2-3 stone just by a small calorie deduct at her size, but clearly she can’t stick to that. She also has a morbidly obese partner so maybe they can get his and hers bypasses. Incidentally I can’t see any weightloss method working if she is living with someone who is determined to stay fat.
