How-To: Training Your Stomach to Tolerate Fuel During Exercise


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.

Nutritional To-do's in Preparation for Next Season


With the holidays over, the off-season continues for many endurance athletes. Others are starting the building phase of their training. Regardless of which category you fall into, there are things you need to do now to prepare you for racing season this spring, summer and/or fall:

1. Review
Review your race nutrition for your top 3 races last year. What went well? What went poorly? Did your nutrition limit your performance? Did you feel like you had enough energy for the entire race? Did you cramp or have digestive problems during the race? Next, review the season as a whole. How did your body and pace hold up? Were you sick often or nursing a recurrent injury? Did you lose or gain a substantial amount of weight? Answering these questions will help you set goals for next season as well as identify the problems you then need to take to a sports dietitian.

Why Detox & Cleansing Hurts

Search for "detox products" online and you'll get over 35,000 hits. Detox diet books number in the hundreds. Surprising? Unfortunately, no. Ridiculous? Absolutely. It's continually shocking to me the amount that some people will pay for products that have absolutely no scientific evidence that they do...anything. The theory behind detoxing is that our body becomes overloaded with "toxins" from the food we eat, mainly coming from additives, caffeine, preservatives, and alcohol. Supposedly these toxins stay in the body, wreaking all kinds of havoc, from weight gain to belly bloat to fatigue. The truth is that this entire premise is faulty.

Talk to any GI specialist and he/she will tell you the same thing: our bodies don't get "backed up with toxins" that come from the foods we eat. The body is perfectly capable of cleansing itself using its own special device: your liver. Ever heard the phrase, "You live-r you die"? You need your liver - can't live without it! It is your body's natural way of filtering out the "bad stuff" and keeping the good.

So why do people keep buying detox and cleansing products, claiming to see results? Many of these products are filled with intestinal irritants, designed to upset the lining of your gastro-intestinal (GI) system so that you go to the bathroom (and therefore think the products is effective). The products claim that this is your body ridding itself of "toxins and years of build-up", when all you have done is irritate your intestines.
 
 
Unfortunately, the consequences can go beyond mere irritation of your GI system. Many detox products or detox diets are downright dangerous. Some products require extreme fasting for days or weeks at a time, in which participants only drink liquids or eat only one or two foods. Taking in so few calories leads to severe muscle wasting (not fat loss). Still other detox products contain laxatives or colonics; these can be dangerously dehydrating and cause electrolyte imbalances in the body. Use the products enough and you will start decreasing how effectively your intestines absorb the vitamins and minerals in the food you eat. Some people become dependent on these "colon cleanses" to go to the bathroom because they have overused them and upset the natural regularity of their bodies.

Looking for a healthy way to "cleanse" your body? Try this:
1. Drink plenty of water
2. Eat whole foods rich in fiber, such as fruits, vegetables, and whole grain.
3. Fuel your muscles with low-fat dairy products and other lean sources of protein.
4. Eat consistently throughout the day: every 3-4 hours is ideal.
5. With the okay from your doctor, be physically active every day.
6. Avoid laxatives and detox supplements.
 
 
So whether it's a pill, liquid, diet, or foot pad (yes, those are out there too), stay far away.
 
Be Extraordinary,
