Other people will try to sabotage you Some people, who often sincerely want to be helpful, will tell you that "it's simple: calories in - calories out", that you "just need to eat less, move more" and eat "everything in moderation", or that "it's just a matter of willpower." Once you've successfully lost some weight, people who feel threatened by your progress may start enticing you to eat more: "Why aren't you eating a full serving?", "Don't you like my cooking?", "You are so skinny now, I'm sure you can have a large piece of chocolate cake." Often times, your dedication and results make them feel challenged and uncomfortable. They may also love to follow your path but it's sometimes much easier to sabotage you so you can go back to your old habits (and gain some weight back) so they don't have to question themselves too much. It can be really hard to stay consistent with your healthy eating plan when people around you are not supportive, so be prepared to handle their reactions.
