Now consider this situation:

A person has a particular body weight, lets say 'x' kg. now if he takes in food weighing exactly 1 kg, then would his body weight increase to "x+1" kg ? or would some of the weight be lost as heat ?

    E = mC^2
    Even one gram loss would lead to enormous energy release.
    If the person does not visit the bathroom before weighing the increase in weight will be 1 KG.
    Actually the carbon dioxide exhaled and the water lost in respiration and perspiration will ultimately lower the weight. However, this is not immediate.
