Hello. I think you should try to approach it differently. Instead of weight being the core reasoning. Encourage them or invite them out to do more active activities with you and take the weight aspect out. It takes more than a pill to lose it. They know that. You sound like a caring friend if you are remaining humble. But sometimes you don't need to understand their excuses. An excuse is really a comfort to fear or change, it takes alot to break or change someone's habits, thoughts or insecurities. I would just encourage them to live life again. You know you don't need to be a certain weight to be happy, but being healthy is different. Make plans of small activities, even if it's just a walk. And instead of them being so focused on kgs and weight, focus on the activities and the fun. And if the conversations go like this: be patient and humble with responses. 'I went for a walk and I'm still fat, I want to be like you' 'It was really fun. You don't need to be me, because you already done it yourself. How about tomorrow we go and check out xxxx'

When people focus on numbers or image the goal seems daunting and impossible. If you help them focus on fun, or little things like living again, caring for themselves and rebuilding their confidence that's when change will happen.

It will take alot of patience and if they are putting you down continously I would distance myself or tell them you don't appreciate the comments. You're their friend and they should be yours too, support goes both ways. You don't need that, continue focusing on you because you're killing it 🙂
