Depending on your situation you may have a greater or lesser need to keep people
from finding out your behaviors.
Don't raise suspicions. Once people realize what you're doing, you'll be watched
and monitored and suspected. Start hiding your habits and practices before
anyone even sees them. It's much easier to keep people clueless than it is to
fool people who know something's going on.
Check the fridge when nobody else is around. Find foods that you would have
eaten and get rid of them, for example, three eggs and a piece of butter. Then
if someone asks, you can say you had scrambled eggs and are really full. And if
they check, the ingredients are gone, which reinforces your story. Consider
dishes and silverware as well.
Don't bring up the subject of food around other people. Have your excuses for
not eating ready in case they should bring the subject up. Some excuses I use :
"My stomach's a little upset", "I'm too (tired, excited, nervous, busy, etc) to
eat", "I don't feel like (whatever food it is), I'll get something later", "I
did eat, didn't you see?", and "I stopped by (Arby's, Burger King, Subway, etc)
If you plan to say you stopped by a fast-food place or restaurant, be sure to
take out several dollars from your wallet (or wherever you keep it) and hide
them someplace they won't be discovered. Be sure also to stop and wait for about
the amount of time it would have taken to eat the food before going home, and
know what you supposedly ordered. The money you hide can be saved up as a
Spend different meals with different groups of people, tell them all that you
had a big meal earlier or will be eating something later on. Make sure the
different people will not be comparing notes. Or plan your schedule so you're
too busy at mealtimes to eat then.
Trash. Watch where you dispose of uneaten food or other "evidence", make sure
that it isn't going to be seen or found by anyone. Wrap food up and throw it
away outside the house. If you live alone, always take the trash out before
anyone else comes over.
Buy food. People are fairly predictable. If they see you buy food and come home
with food, then they just naturally assume that you eat it as well. Get things
like crackers and cookies and dried fruits, keep them in your room, and
carefully pack them out again later to throw away. Careful, this can be a little
dangerous if you're prone to binging and have trouble keeping food around, or if
you feel guilty about throwing food away. If the food's something you don't like
and won't binge on this may be easier to do.
Don't get angry. Don't deny everything if confronted. People will believe a
little truth with a big lie much easier than a huge lie. Act as if it's no big
deal instead of reacting emotionally and people will tend to believe you.
Tell people you're on a diet, you became a vegetarian, your doctor has you
eating only certain things, whatever. Often people will be very helpful in
keeping you from eating if they think there's a socially acceptable reason for
Don't show off your weight loss until you've reached the weight you want to
remain at. People will start to watch you more carefully and maybe ask
questions, and you want to avoid calling attention to yourself.
