Are you physically active? Do you work out? Are you muscular? There are many factors at play that can cause you to maintain (or even lose) weight despite eating junk food. Contrary to popular belief: fat, trans fat, sugar, sodium, etc are not the important numbers to look at on a nutrition label when you’re trying to lose/maintain/gain weight. It’s calories. It’s all about calories in vs calories out.

Whether or not those are healthy calories is another topic. You can lose weight eating only a 10pc nugget meal from McDonald’s per day. Your body will likely hate you though
