While they are great for your body (and weight loss),
flaxseeds are full of fiber, which could impede your workout efforts by causing gas and/or bloating, says
Stella Metsovas, a clinical nutritionist and diet expert in Los Angeles, Calif.
"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."
