It can be hard to keep up with the barrage of diet trends and bold claims that promise to help you reach that feel-great weight, and if you’re struggling to drop pounds and improve your race times, it is even more difficult to wade through the tidal waves of advice. What’s more, nutrition guidance for runners often contradicts even the most conventional dieting advice.

In Heres Exactly What to Eat Before a Half Marathon: A Complete Guide to Weight Loss for Runners, you will find all the details you need on what foods to eat, how much to eat, and how to tailor your training in order to make the weight-loss and running breakthroughs you’re seeking. To get you started on a path to weight-loss success through running, ask yourself these key questions about your running and diet goals before you dive in head first. 

Does this training program fit my lifestyle?

Some people try to follow off-the-shelf training approaches, or follow a coach's training advice to the letter of the law. Most of the time, generic training advice will only work if it is adapted to fit the rhythms of your everyday life—and your unique needs, goals, and time constraints.

If you’re following a training program that requires three or four uninterrupted hours for a long run or demands two workouts on a single day, you need to know if you can reasonably do that. If not, be willing to adapt that program to fit your schedule so you don’t get discouraged and go off track. 

What are my unique eating challenges?

Some people can only shed weight if they keep sugary foods out of sight, while others can only drop unwanted weight by making small, incremental changes. Do some critical thinking about where your trouble spots are—like eating before bed or indulging on the weekend—so you can map out your own personal plan for improvement.  (Heres Exactly What to Eat Before a Half Marathon helps you determine what your unique weight-loss and training obstacles are so you can customize your diet and exercise routine to get over them.)

Do I hold myself hostage to high standards?

Whether it’s logging 100-mile months or glimpsing that dream pace, it is powerful and confidence boosting to see what we can do with intense focus. But if you hold your training hostage to the fastest or farthest you’ve ever run—or what your younger body could do—you’re setting yourself up for chronic disappointment.

Think instead: How many miles and what kinds of training loads are sustainable before my body, schedule, relationships, and work performance start breaking down? Pace your training the same way you would an easy run, and ease into a rhythm that feels sustainable enough that you could maintain it for a very long time.

Can I sustain this particular diet?

If an approach to eating feels like a sacrifice, ultimately it’s going to backfire. If your daily diet is too expensive, inconvenient, lacks a balance of the right nutrients, leaves you feeling depleted, or feels like you’re punishing yourself, it’s not going to last.

When trying different eating approaches ask, “Can I maintain this for the rest of my life if I had to?” Nutrition - Weight Loss.

What are the main “priorities" with my running?

In your running life, the one thing that should not change over time is the enjoyment and good health you get from running.

Keep “happiness” as the one non-negotiable of your running and be flexible enough to let all other factors—PR goals, weekly mileage, terrain, and racing schedule—evolve. If you handcuff your running “identity” to a single type of training, race distance, or a specific number of miles logged, burnout and injury are all but guaranteed.

Can I adapt my diet as my running changes?

As a runner, you will always want to make sure you’re getting a balance of wholesome carbs, protein, and healthy fats that your nutrition needs. But your cravings are going to change as your training changes, and so will your appetite, schedule, time, and interest in cooking.

Many runners get tripped up because they continue to eat marathon-sized daily calorie loads long after they cross the finish line, or they reward themselves for workouts with sweet and savory treats. Adjust the calories you consume to the training that you’re doing and pay close attention to why you are eating, customizing your meals and snacks to fuel your workouts and recover from them.

How will I brush off setbacks?

Progress typically involves one step forward, two steps back. When Olympian and 2015 USATF Marathon Champ Blake Russell was shedding the 40 pounds she gained with each pregnancy, she clung to her coach’s insistence that talent never goes away. “Some days the workouts were terrible because I was exhausted. Other days, I saw a glimmer of my old self....I wanted that feeling again,” she said.

Decide what you will focus on when the chips seem down. Russell got back to her old self again when she won the 2015 Los Angeles Marathon and the USATF Marathon Championship. If she had given up at the sight of exasperating numbers on her training watch or the bathroom scale, she would have missed out on that.

Can I learn from my small mistakes?

Success is not about 24-hour perfection. It’s about progression. And weight loss is a process of learning what works for you and what doesn’t.

Think of each diet slip up as a lesson. Say you’ve gone cold-turkey on sweets, but then find yourself with a voracious craving for chocolate. Then you’ve learned that cold-turkey approach isn’t for you. If you find that you’re rifling through the refrigerator after your good-old dinner standby, you’re learning that it may be time to mix up your menu options. (In Heres Exactly What to Eat Before a Half Marathon you’ll find full-proof strategies to get back on track after you’ve been derailed by injury, an unplanned break from running, or a particularly indulgent night of eating and drinking.)
