Foods can Sabotage Your Workout

Flaxseeds: 
You definitely want to limit the amount of fiber you take in 2 hours before and after exercising. In addition to flaxseeds, stay away from fiber supplements, bran, and high-fiber breads and opt for a mixture of protein and carbohydrates instead right before your workout.

Hummus: 
Bean-based foods (such as hummus) are high in indigestible carbohydrates that may cause uncomfortable gas and bloating.

Green bananas: 

While bananas are a great pre-workout snack, make sure you grab a ripe one! Unripe fruit isn't a good idea before you work out, as it could cause uncomfortable gas and bloating. Choose a banana that's completely free of any green at the stem. Brown spots on the skin indicate it's in the ripe stage. At this stage the sugar content will be absorbed easily, otherwise, the unripe banana is in the starch stage and more difficult to digest.

Thai or Mexican food: 

Spicy foods may help you burn up more calories overall, but they won't help you burn more during your workout if you eat them right beforehand. Even if they are 'healthy' dishes, spicy leftovers can cause heartburn if they backwash into the esophagus.

Hard-boiled eggs: 

Hard-boiled eggs are a great source of lean protein, but they don't provide carbohydrates for energy. Plus, their protein stays in the stomach and takes a long time to digest, which could weigh you down at the gym.
