20 Surpising Foods that Slow Down Your Workout


“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.”

Gel Packs

Think that energy gel is a great way to prep for your workout? Think again! “Unless you are very athletic (engaging in over 90 minutes of cardiovascular training per day), chances are you don’t need those gel packs, Metsovas says. “Taking in all that sugar will disrupt insulin levels and lead you to a dietary-binge later on in the day.”

Dairy
While low-fat dairy may be part of a healthy diet, consuming it before a workout could slow you down. “Most athletes I work with have issues consuming dairy 2 hours before and after exercise,” Metsovas says. “I’d advise limiting the use of dairy if you feel lethargic, acidic, or experience excessive burping.”
Flavored Water
Even though most flavored waters are touted as great ‘fitness’ drinks, many are full of sugar, or worse, artificial sweeteners that could hinder your workout.”I would not recommend drinking artificially sweetened beverages prior to working out. I’m against artificially sweetened anything. Artificial sweeteners have been shown to disrupt beneficial bacteria in your gut, and optimal digestion and absorption of nutrients begins in a healthy gut,” Metsovas says.

High Sodium Foods (Roasted Nuts)
Even though nuts are a great snack (and can help with weight loss) most roasted nutsare also salted, and salty foods can disrupt the delicate fluid-balance required for optimal workouts, Metsovas says.”I’d avoid [high sodium foods] at all costs. Using a little bit of salt in your meals is OK, but stay away from the following foods: beef jerky, salted and roasted nuts, lunch meats, and processed snack foods like chips (you shouldn’t be consuming these foods anyway).”Read more here
