Even Keel

If you're still questioning how much to eat the golden rule is never to let your daily calorie allowance fall below 1,200 if you are a woman and 1,500 if you are a man. Falling below these daily allowances can do real damage to your metabolism and result in excessive loss of lean muscle tissue. Along the same lines as not eating enough and having an energy crash, caffeine, alcohol, sugar, and chocolate are all known for mood-altering effects, ranging from waking you up to calming you down, but they can also trigger mood swings, irritability, and feelings of anxiety and stress.
