Like you said in a comment and in the post, big wake up call for your friend. Most friends didn't say anything about my shape, but luckily one friend did. And I finally took action. Daily on my bike and walking at least 7 km a day. Plus healthy food and focus on the calories.
In your example, man, you need to walk like 25-30 km to burn all the snacks, lol.
I hope she loses weight in the near future.
