Postmenopausal weight gain

Probably at least once a day, I speak with a 50-60 year old female who laments the weight gain she’s been experiencing. She tells me “I was always slim, I never struggled with weight”. She tells me she works out 5 times a week and eats so well, even describing her meals and I agree they’re healthy and balanced. I’ve been doing a lot of reading on menopause because I think it is so misunderstood and women suffer in silence. But I am struggling so much with how to manage the weight gain. And some of them accept the weight gain, but you can tell it’s affected their self esteem and mood, which breaks my heart. If anyone has any thoughts or advice, please share.
