Your body's normal state (homeostasis) is changed by stress. The hormones, adrenaline and cortisol, are secreted in response to a stressful situation. The "fight or flight" response to stress is intended to give you the energy to take on or run away from a particular situation. Stressful situations that go on for months or years signals to your body that the normal state includes excessive amounts of adrenaline and cortisol.
As it relates to metabolism, adrenaline makes your fat cells more efficient at turning fat into energy and speeds up your metabolism. On the other hand, cortisol increases the amount of glucose in your blood and creates more energy.
During the holiday months, this excess adrenaline and cortisol builds up in your body. Unused excess energy will be stored as fat.
Chronic stress, extra stress brought on by the holidays or stress with no end in sight has major health implications. Adrenaline will continue to be secreted but your body and your fat cells will build up a tolerance to it.
This means that your fat cells won't be converted to energy and cortisol will continue to increase glucose in your blood. This means the fat gain and weight gain begins to happen if left unchecked.
Life continally has stressful situations and life sometimes brings unavoidable stress, like during holidays. Regular exercise helps you to deal with stress and bring your body back to the true normal state (or as close as possible).
Exercise consistently during the holidays and take care of yourself!
