Of course the real answer is, “NO” it’s not your friends that make you fat; it’s the decisions you make and execute that lead to the results you realize in your life. However, did you know that your choice of friends may contribute to weight challenges? (Don’t lose sight of the difference between ‘contribute’ and ’cause.’)
If you hang with people who eat at greasy, fast-food, establishments you are obviously more likely to frequent those places, especially when you are in their company. Also, if your friends regularly order things like the mega-burger, jumbo-fries and wash both down with a large milk-shake, it ‘normalizes’ the behavior of making poor nutrition selections and sort of gives you ‘permission’ to do the same.
On the other hand, if you hang with people who generally choose more reasonably sized selections of nutrition-dense foods, and they often leave some of the food uneaten on their plate, you are more likely to behave in a similar fashion.
The lesson here is: Be aware of the behavior patterns of the people with whom you hang. Do their choices support or sabotage you?
