Answer:

Eating is one of the most social events in our society. It is for precisely this reason that many people are overweight.

People tend to eat more when they eat with other people than when they eat alone. They are also more likely to eat dessert when with friends.

• Try not eat like friends who aren't watching what they eat. Everyone seems to know somebody who can eat like a horse and never gain an ounce.
• They may be indulging in foods that won't help you towards your goals if you join in. There will be pressure to copy their eating habits.
  
• This is not to say you should always eat alone or never eat with friends, just be aware of what you are putting into your mouth.
• Remember, only YOU have the final say over what you put into your mouth. Nobody is putting a gun to your head saying "eat that cheesecake." If they are, then you probably need new friends.
• Another thing to watch out for is that "occasional" nibble off somebody else's plate. It is "regular" if you take an "occasional" nibble every time you eat and can be a source of many hidden calories.
