Serious training requires serious preparation; nail these strategies to take your performance to the next level
The other day, I overheard some of my athletes debriefing each other after an intense conditioning workout. The theme of the conversation was earning their next meal by going hard in the gym. This mindset is flawed. Unfortunately, it’s pervasive in the industry, and it’s even the motto for some nutrition professionals. Stop trying to earn your food by working out! Instead, earn your workout by following these 4 nutrition tips to upgrade your athletic performance, and even recover better.
A common complaint I get from athletes at the gym is that they sometimes feel like their performance has stalled, or they feel hungry all of the time. After assessing their sleep and some other lifestyle basics, I usually ask them to give me a food journal detailing at least a few days of eating. More often than not, they are lacking in at least a couple of the areas listed below and not eating enough. How do we get them back to jump kicking their workouts in the face? By making some basic tweaks to their diet to crank the dial toward enhancing performance.
Basic food portioning for performance
When eating for performance, being consistent with the portion sizes of your protein, carbs, fat, and vegetables is key. We need to keep a regular supply of nutrients coming in to nourish our bodies, regulate energy levels, and prepare us for the rigors of the day. I recommend my athletes consume three meals per day, breakfast, lunch, and dinner, plus one to two snacks.
The macronutrient composition of these meals and snacks can vary, depending on the needs of the person. I rarely have people track macronutrients. They need to show me that they can follow a basic portioning strategy first. Keep in mind, these are estimates. Try not to overthink the portion sizes. Even if we were tracking exact macronutrient numbers, we would still be estimating. Estimation in nutrition plans is inevitable.
Macronutrient portioning for breakfast, lunch, and dinner
PROTEIN: One palm of lean protein for women, two palms for men. Aim for high-quality cuts of meat that are about the thickness of your hand.
CARBOHYDRATES: One cupped handful for women, two cupped handfuls for men. Aim for whole food sources such as fruits, rice, potatoes of any variety, quinoa and similar grains, fruits, and even sprouted or fermented breads like sourdough or rye.
FATS: One thumb for women, two thumbs for men. The thumb-size equates to about one tablespoon of oil or a small handful of most nuts. Keep that in mind when adding dressing to a salad. If you choose to have a fattier cut of meat at a meal. You can likely skip adding portions of fat to that meal.
VEGETABLES: One fist for women, two fists for men. Attempt to eat the rainbow when it comes to vegetables. These will be your main source of phytonutrients, fiber, and antioxidants. If you currently don’t eat a lot of vegetables, start small. Add one or two types per day, following these portion guidelines. After a couple weeks, start adding things that look interesting. Do that every couple of weeks, and you’ll be eating the rainbow in no time.
Snacks should look like mini-meals. Think half-sized versions of the above guidelines. Aim to have a small serving of protein, carbs, fat, and a fruit or veggie. Imagine an “adult lunchable”: a serving of deli meat, sliced apple, and some nuts. Voila! You have a well-balanced snack. They work great for children’s lunches, as well.
For on-the-go, I’m a big fan of Rx Bars. They taste good (they don’t taste like science), they’re satiating, and they’re made with mostly whole-food ingredients. Shakes are another great option because you can blend them at home, chill them at work (assuming there is a refrigerator), and shake it back up when it’s time to eat.
A word on pre/intra/post-workout nutrition
I get a fair amount of questions about when and what to eat around a workout. The reality is, for general fitness, eating three meals, plus a snack or two, will keep you fueled and recovered each day. (assuming you are mostly consistent with your portion sizes and you prioritize eating high-quality food)
For those of you who want a slightly more advanced approach, your post-workout meal should include a portion of protein and a portion of carbohydrates. We want to keep the fat low because fat will blunt the absorption of the protein and carbohydrates. Protein helps repair the damage done to muscles through exercise. Carbohydrates replenish the expended glycogen in our muscles, which the muscles use as fuel while contracting during bouts of exercise.
I encourage you to stick with whole food options for post-workout meals, but I understand that some athletes find it hard to stomach a whole food meal after an intense workout. In that case, a protein powder can be used to quickly get the nutrients your muscles need to start making repairs. You can use any type of protein you like, but try to get the highest quality you can afford.
Make friends with carbohydrates
Over the past few years, carbohydrates have been demonized by overzealous food bloggers and would-be nutrition gurus. The same thing happened in the 1990s with fat. At the time of this writing, fat is the superhero of the nutrition narrative. The fact is, carbohydrates are highly useful, and, in my opinion, essential to human performance.
Carbohydrates come in three varieties:
A big release of insulin post-workout can be very useful because it will help the muscles replenish the glycogen lost during exercise. This is the best time to eat high-quality, simple carbohydrates. However, a big release of insulin before bed or during times of rest/regular activity will be less useful. Outside of your training time, aim to stick to vegetables and whole-grain options for your carbohydrates. They’ll take more time to digest, which will help keep your blood sugar controlled and your energy levels stable.
Adults should be consuming around 130g of carbohydrates per day. That’s just for very basic daily functions. If you follow the portioning guidelines above, you’ll have no problem hitting or exceeding that figure. If you’re very active, have a physical job, or find that you metabolize carbohydrates really well, you’ll definitely want to eat enough to support your activity levels. This will take some experimentation, but the portions outlined in the previous section will be a really good start.
Water is the most important element of our very existence. As athletes, staying on top of hydration is the best thing you can do to set yourself up for success. Compared to the nutrition guidelines above, the guidelines for hydration are fairly simple. Try to drink about ½ of your body weight in fluid ounces each day, as a minimum. Of course, you can drink more, if needed, especially if you are training in high heat or have multiple training sessions per day.
This minimum amount is a great starting place because it should help you avoid the pitfalls of dehydration, such as dizziness, fatigue, lowered mental acuity, irritability, nausea, and cramping.
I prefer this great “morning ritual” cocktail that will help you get a head start on hydration for the day. Here’s the recipe:
Of the three main macronutrients–protein, fat, and carbohydrates-protein is the one that must remain constant for athletes and active individuals. The amino acids in protein are the building blocks for our muscles and organs. If we don’t ingest enough protein, then our bodies will start plundering it from itself, mainly from muscle tissue. The unique thing about the amino acids in protein, when compared to fat and carbohydrates, is that the body will generally either use them for building and repair of tissue, recycle them, or excrete them. Protein also takes more energy and time to digest than carbs and fat, so it will help keep you feeling fuller longer, which is great for fat loss.
How much protein should you eat, and what constitutes a “high protein diet”? Well, there aren’t any well-defined guidelines. The US RDA for protein intake is 0.8g/kg of body weight. That isn’t very much. Right now, I weigh about 88kg, so I would need about 70g of protein to keep my body properly functioning on a normal level. Personally, I get that amount ingested by lunch, so does that mean I’m on a “high protein” diet? Is that even safe?
We’ve been told all kinds of narratives over the years about high amounts of protein is bad for our kidneys, causing liver damage, and causing osteoporosis. Currently, there is no evidence for these claims. In fact, if we want to get stronger and burn more energy through exercise, we need to make sure we eat plenty of protein for our body to repair and rebuild the damage we do in the gym and on the field of play.
There’s an old bodybuilding standard of consuming at least 1g of protein/pound of bodyweight or 1g/2.2kg of bodyweight. Even at these levels, there’s no conclusive evidence to support the claims that protein is harmful. If you follow the guidelines in the section on portioning above, you’ll likely be somewhere between 0.8-1g of protein/2.2kg of bodyweight, and for most of us, that’s plenty to recover and perform.
