#1.) ANYTHING HIGH IN SUGAR. When you’re tired half way through the day, don’t eat a candy bar. Sugar gives you a quick jolt of energy, but your body metabolizes it instantly. And once it does, you feel even MORE tired.

#2.) ANYTHING HIGH IN FAT.
It’s kind of the opposite of sugar. Eating a steak DOES give you energy, but it doesn’t give you much of an energy BOOST because it takes your body a long time to metabolize all the fat in red meat.
–Fish and chicken are better if you’re feeling tired.
#3.) ANYTHING WITH TRYPTOPHAN.
When you hear the word tryptophan, the first thing you think of is Thanksgiving turkey. But a lot of people forget that even a turkey SANDWICH has tryptophan in it.
–And so do a lot of other foods. The most common are: milk, corn, and brown rice.
#4.) TOO MUCH CAFFEINE.
It makes you tired because it interferes with your sleep. Caffeine can make it tough to fall asleep even if you drink a cup of coffee 12 HOURS before bed.
–And even when you DO fall asleep, too much caffeine makes you tired the next day because it screws with your REM sleep.
#5.) BOOZE.
Alcohol slows down your central nervous system and acts like a sedative. And if you’re running low on sleep already, even ONE BEER can make your energy level nose-dive.
