Do you feel hungry when you see someone else eating ?
I will be honest , I do .. usually during lunch break at work , i keep sitting at my desk and dont eat .. but the minute I smell good food and see colleagues eating , my stomach starts to go mad and grumbles and grumbles
I'm used to not eating as much as others but I have to in order to keep shape.... I also have a terrible level of endurance and the dicipline of a guardsman.
That said I admit if the other folk are overdoing it and happen to be going on an all you can eat buffet than I will avoid the temptation and go for a stroll...
CB when your stomach starts to grumble...why not eat? If you are avoiding to eat too much then just snack on carton of cherry tomatoes or cut up some cucumbers....or munch on baby carrots.....these will keep you full but will not let you overload on calories.
