A mum is looking for advice, after she put both of her twin daughters on a diet, even though only one is considered overweight.

The mum has 14-year-old identical twins, Meagan and Alana, who are both five feet tall, or 153 cms. Megan weighs more than 68kg while Alana tips the scales at 43kgs.

“They used to be the same weight until they were around seven, when Megan started getting chubby, but still healthy weight,” the mum explained.

“When she was 11, Megan was considered medically overweight. I went to a doctor for advice, and he said that I shouldn’t worry too much since a lot of kids gain weight right before puberty, and then ‘balance out’ after their growth spurt.

“The twins had their growth spurt last year, and Megan’s weight has only increased since then, to the point where she’s actually obese.”

The mum said she did go to multiple doctors, who have all said that neither of the twins have any medical conditions that would impact their weight.

“So I decided to implement a healthy diet for the entire family.”

“I slowly started to cut back on sugar, junk food, and unhealthy snacks. I cook them high volume, low calorie meals full of vegetables and protein so that they still feel full after eating. Neither of the twins are very athletic, so I’ve also tried encouraging them to engage in physical activities, like swimming, bike riding, trampolining, etc.

“I tried putting emphasis on staying healthy instead of losing weight.”

But eventually one of the twins realised what was happening, and now she feels like she’s being ‘punished’ for her sister being overweight.

“Alana guessed that the real reason for this new diet is because I want Megan to lose weight. She started complaining that it’s not fair that she also has to diet because her sister’s fat. I told her that I didn’t want Megan to feel singled out and feel as though she’s the only one being punished for her weight. Am I the a**hole?”
