5 Foods You Should Never Eat Before a Workout

By now, we all understand the importance of fueling up before an intense sweat session. What you may not know is you could be sabotaging your workout with the wrong foods. Avoid these five at all costs.

Skip the pre-workout hummus or lentil soup. Though both of these options are high in protein, the amount of fiber found in legumes can cause uncomfortable bloating and indigestion during your workout.

Nowadays, guys are choosing lower-carb bars, but before a workout your muscles need energy to burn. And depending on how intense your workout is, you’ll need more or less carbs in your bar. Protein itself is a slower-burning source than carbs so it might not give you the immediate jolt you need to power through a demanding lifting session.

Energy drinks might seem like a good idea, but unfortunately they can have some nasty side effects like bloating and diarrhea because of the excessive sugar—neither of which you want in the middle of a workout. Certified personal trainer Nate Miyaki says, "I either have people eat nothing pre-workout [if they've eaten a mixed meal within the last 2-5 hours or so, there are plenty of circulating nutrients to fuel the workout, or some simple carbs like one or two pieces of fruit.  If the workout is going to be longer than 60-90 minutes, that's where sipping on a sports drink may be applicable."

While carbs are good to fuel up with pre-workout, "simple carbs" like candy or cereal could have a negative effect by causing your blood sugar to drop. "If it's one or two hours before, I'd avoid high-glycemic carbs eaten alone. This can trigger rebound hypoglycemia in some [blood sugar spikes and crashes] which can lead to fatigue, light headedness/dizziness, energy crashes, and poor performance," Miyaki says. 

Opt for oatmeal or quinoa instead.
