If you鈥檙e searching for a pill to get you lean fast or magically improve your mile time without putting in the work, it鈥檚 time to sober up. There is no quick fix. Train smart, work hard, and eat the right way and you鈥檒l get the results you鈥檙e seeking. Here are nine common nutrition mistakes many beginning runners make and how to fix them.
Your Diet Torpedoes Your Training
The fix: Treat your diet like it鈥檚 a part of the training plan. 鈥淵ou have to train a certain way and eat a certain way to get the body to burn fat and lean up,鈥 says Krista Austin, sports nutritionist for several U.S. Olympic teams and founder of聽. That means no more self-sabotage by eating high-glycemic carbs (like waffles with syrup) at every meal or starting all your runs on empty.
Instead of focusing on how much protein or carbs you need before each run or workout, consider your daily needs. Recent research suggests that what you eat throughout the day matters much more than what you eat immediately after exercising.聽
You Give Up When the Going Gets Tough
The fix: Training at threshold鈥攁 faster pace that you can maintain for 50 to 60 minutes, or 10K race pace for beginners鈥攔evs the metabolism and gets you fit fast. But remember to keep upping the pace as you progress.
鈥淎nyone who鈥檚 new to running will naturally end up functioning above their threshold quite a bit because their running mechanics are so inefficient,鈥 says Austin. That鈥檚 why brand-new runners often drop weight and increase fitness quickly. Once these runners start adapting to running consistently, however, that progress slows, and they need to increase their training stimulus to keep seeing results.
If threshold training leaves you feeling fatigued, Austin suggests occasionally sipping G2 or flavored water with electrolytes during your workout to increase performance without overloading on calories. 鈥淭hese high-glycemic carbs impact the brain and taste-bud receptors, and that creates an ergogenic [performance-boosting] effect.鈥
All You Eat Are Carbs
The fix: Runners whose number one goal is to lose weight can cut the pasta, bread, and cereals and have enough energy to complete many of the easy runs in 30 to 60 minutes. Most healthy diets will still provide enough incidental carbs鈥攂y-products of fruit and beans鈥攖o fuel you, says Greg McMillan, founder and head coach of McMillan Running.
When it comes to your more intense training days,聽increase your carb uptake,聽just don鈥檛 think it all has to come from pasta. “You can do it with more natural, less-refined carbs like rice or quinoa as part of your meal,” says McMillan.
Vegetables Are Only the Side Dish
The fix: Eat whole foods that are as close to their natural state as possible. This will steer you to the most nutritious, fiber-filled foods that promote overall health.
鈥淗igher-quality foods鈥攙eggies, fruits, nuts, seeds, healthy oils, lean meats and fish, dairy, and whole grains鈥攖end to have a higher satiety index,鈥 says Matt Fitzgerald, a certified sports nutritionist and author of the Racing Weight series. 鈥淚f you have a high-quality diet and eat enough to satisfy your appetite versus if you have a low-quality diet and eat enough to satisfy your appetite, you鈥檙e going to eat a lot more calories on the low-quality diet.鈥
If you focus on food quality, the quantity question will sort itself out (even the most monstrous appetites can stomach only so much fiber in one sitting). Combine a high-quality diet with consistent, progressive training, and you鈥檒l achieve both weight and performance goals.聽
You Think You Can Get Skinny and Fast Simultaneously聽
The fix: Focus on weight-loss efforts during quick-start periods, or the four to eight weeks that immediately precede the base-building phase of a training cycle, Fitzgerald suggests. Create a manageable calorie deficit during this time, and adjust based on how your body reacts.
When you start your training program, shift your focus to fueling your body to meet the increased performance demands, not on counting calories. 鈥淚f you use more energy, you have to take in more energy. If you perform poorly in workouts or are lethargic between workouts, you might not be taking in enough calories,鈥 says Fitzgerald. 鈥淵ou can run the numbers and see a calorie deficit, but when you exercise a lot and don鈥檛 get enough calories, metabolism slows to a crawl. You get the opposite of what you鈥檙e looking for.鈥
You Think Being a Runner Means You Can Eat Whatever You Want
The fix: 鈥淭he average person eats three additional calories for every 10 extra calories they burn through exercise,鈥 says Fitzgerald. 鈥淵ou have to manage it with high-quality foods, pay more attention to nutrient timing, and become aware of satiety signals so you don鈥檛 overeat by plate cleaning.鈥
This doesn鈥檛 mean you can鈥檛 treat yourself every now and then. Just keep in mind that your post-run reward counts as a part of your total daily intake.
鈥淲e only burn around 100 calories per mile, no matter how fast you run that mile,鈥 says McMillan. 鈥淵ou can look at any food鈥攁 doughnut or a Coke鈥攁nd you can realize, 鈥楬oly crap, I can drink this much faster than I can run the miles to burn it.鈥欌
Don鈥檛 make the mistake of rewarding every long run and race.
You Train and Live by the Spreadsheet
The fix: To progress and improve as a runner, sometimes you need to look beyond the numbers (miles and times) to learn what works best for you during training. Pay attention to how your body responds to the food you give it before, during, and after running. Write down what works and what doesn鈥檛, and adapt.
鈥淕ood coaches ask how athletes feel versus focusing only on the numbers that are pushed out on a heart-rate monitor or the splits run on the track,鈥 says Austin. 鈥淚t鈥檚 the same thing with nutrition. You ask athletes how it feels rather than just saying, 鈥榊ou have to eat this.鈥欌
You Live on Sports Nutrition
The fix: If you ran as hard as you could, you would empty your glycogen stores in 90 minutes to two hours, but how often do you do that? Sipping Gatorade throughout the day isn鈥檛 much different than drinking soda鈥攜ou鈥檙e just downing a bunch of sugar with some added electrolytes.
Use sports nutrition products, such as聽gels, gummies, energy bars, and sports drinks,聽sparingly, says McMillan. Stick to real food. Eat the high-quality foods mentioned above, drink plenty of water, and avoid processed foods with added sugars, salt, and fats.
You Overdose on Caffeine
The fix: 驰别补丑,听caffeine can boost performance, but it can also aid in glycogen restoration鈥攖he process of restocking energy supplies to your muscles鈥攆or those dreaded two-a-days.
But beginning runners should know that we all metabolize caffeine differently. Regularly taking the ergogenic aid can make its effects less potent on race day. 鈥淚 tell my athletes to see how little caffeine they can take prior to a training session to still get the effect we鈥檙e going for, and to only use caffeine on hard days,鈥 says Austin.
Experiment with your caffeine intake while you鈥檙e training. There鈥檚 only so much caffeine the intestinal system can handle at one time, so loading up on caffeine before a workout or race can put you in the bathroom鈥攆requently.
The bottom line: Dial in the amount of caffeine you can tolerate prior to intense workouts, and then hold off until race day.
