As a sports dietitian, I spend a good amount of time dispelling myths created by the media, movie stars or the like. Whether it is some supplement that promises toned abs and gigantic muscles or some method of eating that is SURE to result in 20 pounds of weight loss in a week, the media is never short of ways to play to the emotions of those desperate for a solution. But of all of the practices I despise, hare are a few that top the list.
1. Detoxing
By far the one of the most irritating practices that continues to be encouraged is detoxing. By detoxing, I mean using a product (shakes, pills, powders, etc.) or elixir (think lemon juice and chili powder, for example) to "clean out" the gut from months or even years of food byproduct build-up or toxins spread throughout the body. This entire practice is based on a fallacy, as digestive by-product does not build up in the gut, so there is no need to clean out anything. Plus, the body rids itself of toxins very well on its own using the liver without the need for additional help. What most of these products do is irritate the lining of the intestines, resulting in diarrhea...which makes the user feel like he/she has achieved something. Want to detox? Regularly focus on eating whole grains, fruits and vegetables and drinking plenty of water to keep the body and intestines working properly - no products required.
Many athletes that walk through my door report difficulty tolerating food or even fluids during workouts. But, fueling during exercise lasting longer than 60 minutes is hugely important to overall performance and body composition goals. So, training the stomach like athletes train muscles needs to happen. The question is, how exactly does one DO that? Well, I'm glad you asked....
1. Start with your easiest workout
By easiest, I mean the workout that is either lowest intensity or during which you seem to tolerate fuel best. It may mean a cycling workout instead of running, a lifting day instead of speed or a long swim day instead of dry land.
When I was in high school, I often suffered "GI (gastrointestinal) consequences" after hard workouts or races. However, I just assumed that was part of running hard and there was nothing I could do about it. I wish I had known back then what I know now: GI distress is not something you have to grin and bear; GI distress can be avoided and prevented. Whether it is diarrhea, stomach cramping or nausea, these symptoms can be controlled with proper sports nutrition techniques.
1. Hydrate
Poor hydration is the most common cause of GI issues both during and after activity. This is because during activity, the body shunts water to the muscles to fuel exercise, leaving the gut with whatever is leftover. In times of dehydration, what fluid is left is often minimal. Athletes should take in about 2 cups of fluid 2 hours before a workout and 1 cup of fluid 1 hour before a workout. Once the workout has started, drink 8-12 ounces of fluid per hour of workout. This is obviously a huge range that can be perfected with practice and assessment. Not even close to where you should be? Start with small increases of perhaps only 25% more fluid per hour than you are drinking now. Training the gut to absorb more water is possible. Also realize that electrolyte supplementation may be necessary to help the body hold on to water and stay better hydrated overall.
