It's not that simple. What the article describes is a very common problem with people who get healthy and lose a lot of weight. Their 'friends' often end up hindering their goals though often not on purpose.
When I talked to a friend of mine about her weight loss the hardest part for her was losing all her other overweight friends. They would constantly ask her why she was getting up at 5am or eating healthy or training for a marathon and then would make comments that it's pointless. They didn't drift apart because their interests changed, she had to cut them out because they were holding her back.
