Coach Renee Eastman’s Top Weight Loss Mistakes for Cyclists

As athletes work toward fitness and performance goals, many focus on losing weight as well. Over 20-plus years of coaching, I’ve found some common things that trip people up. Below, I’ll share common mistakes I see athletes make when pursuing weight loss goals.

But first…

Before I dive into those topics, a few clarifications. I am a Certified Sports Nutritionist through the National Academy of Sports Medicine (NASM) and I’ve been coaching and consulting athletes about nutrition for decades. That said, articles like this one contain generalized advice that may or may not apply directly to you. Nutrition is not a one-size-fits-all subject and I encourage you to work directly with a nutrition professional for personalized guidance.

I have tailored the advice to an audience I’d expect to be reading a CTS blog post. That means an amateur endurance athlete who might train on average 4-6 days a week. Your daily exercise sessions are usually 2 hours or shorter, with occasional longer sessions.

Also, it is important to understand you don’t need to lose weight. Weight loss is not a mandatory part of progressing as an athlete. Philosophically, my CTS colleagues and I think “fitness first”, meaning we prioritize training and activities that improve power output, time-to-exhaustion, durability, sport-specific skills, and mental skills. Weight loss often happens as a natural result of a fitness first process, but sometimes body weight doesn’t change at all. And that’s fine.

But, if losing weight is a goal you’re pursuing, here are some of the mistakes you should try to avoid.

Mistake: Underfueling your training

See if this scenario sounds familiar: After following a calorie-restricted plan all week long, you go for a big ride on Saturday. When you arrive back at home you eat everything in sight. You then spend the afternoon raiding the fridge and never seem to overcome that empty feeling.

That rebound effect commonly occurs when you create a significant and unsustainable calorie deficit. And it happens despite your best intentions to sticking to your plans. High levels of fatigue and hunger exhaust an individual’s willpower and decision-making processes.

Even without a big ride, the same thing often happens as people move through their day. People stick to a plan through the day (while they are the most active) but then go off the rails in the evening.

Finding it hard to stick to your nutrition strategy after rides or in the evenings may indicate you’re being too aggressive with your calorie deficit. Compromised training performance is an equally significant negative outcome to this pattern. This occurs because you’re going into training with low energy availability. It’s a lose-lose situation. You can end up with a net-zero on weight loss because caloric overcompensation wipes away the big calorie deficits that already ruined your training.

Mistake: Caloric overcompensation

Caloric overcompensation as an intentional reward for hard training session is another problematic scenario I see. The thinking goes, “Hey, I just rode 4 hours, so I earned this burrito the size of my head.” Sure, recovery nutrition is important, but it’s more important to be well fueled before your training session. When you’re well fueled, you can use that energy to go harder, faster, and create a greater training stimulus. In many circumstances, eating normally after training is sufficient to refuel to recover for the next hard session. Rapid post-training replenishment is of more concern for athletes training multiple sessions a day or back-to-back days with high volume or intensity.

Another caloric overcompensation pattern I see relates to misunderstanding exercise’s role in fat loss. You can’t outrun a bad diet, and that leads into the next mistake I’ll mention.

Mistake: Overemphasizing exercise calories burned

The idea of calories in vs. calories out for fat loss is a true but overly simplistic concept. Cardiovascular exercise expends a lot of energy and helps contribute to a caloric deficit. However, two often-overlooked factors are that most fat is burned outside of exercise, and during exercise endurance athletes obtain a lot of energy from carbohydrate.

Reality: You burn more fat outside of exercise

Individual athletes are more or less metabolically efficient, which alters how heavily they rely on fats for fuel at low to moderate intensity. As exercise intensity increases, so does the reliance on carbohydrate to provide energy. For most athletes riding in Zone 2 (Aerobic Endurance intensity), carbohydrate contributes about half of the energy burned. By the time intensity rises into Zone 3 (Tempo intensity), most energy is supplied by carbohydrate because energy is required faster than it can be supplied by breaking down fat. At Functional Threshold Power (FTP, lactate threshold intensity) or higher, the energy balance shifts even further to predominantly carbohydrate and very little fat.

Cardiovascular exercise is great for burning calories. Low-intensity aerobic exercise tips the balance toward more fat than carbohydrate being used for energy. And large volumes of lower intensity exercise are important for aerobic development. However, in a 24-hour period you burn the greatest amount of fat at rest or during activities of daily living.

Reality: Exercise may not increase total daily energy expenditure

Exercise often impacts activity levels for the remainder of the day, which affects total daily energy expenditure. When I complete a big 4-hour ride, I’m less active the rest of that day and probably the next day, too. Often the days I burn the most total calories are when exercise is more moderate, but my non-exercise activity is the greatest.

Weight Loss Mistake: Training to just burn calories

I also see athletes misusing training sessions with the goal to burn off weight. Athletes add extra exercise time, which creates junk training or, even worse, impaired recovery. In more extreme cases, athletes refuse to take days off or refuse to go easy in recovery sessions because they worry they’re burning too few calories for the day.

Here’s the dangerous mismatch of training goals: exercising just to burn calories for weight loss vs training effectively to improve fitness. Most athletes in this scenario miss the mark on both. Athletes who focus on excessive exercise to lose weight are also the ones most likely to under-fuel training. As mentioned, this often leads to caloric overcompensation later. Instead, I recommend focusing on training to improve fitness first. Sometimes that will be high-volume, low-intensity sessions. Other times that it will mean short, high-intensity work. And, of course, effective training always requires rest for maximal adaptation.

What to do instead

Fuel your training first

A more effective plan utilizes fueling strategies to maximize performance. This means pre-loading training sessions for maximum effectiveness and consuming more energy before and during big training sessions. Properly fueling your training improves workout quality and makes it easier to avoid post-workout caloric overcompensation. When an athlete increases intake on harder training days they are also less likely to feel famished during the following recovery day.

Creating massive caloric deficits from under-fueling big training days makes it difficult to stay on track the long term. You’re better off creating long-term habits that support high-quality training.  Short-term solutions lead to short-term results. Sure, following a trendy diet will likely result in some weight loss. But, if you can’t thrive on those dietary practices you’ll stop. Then, you’ll return to old habits that encourage weight gain.

Be patient and iterative

It’s appropriate to use a period of focused time to practice with dietary changes. You want to see what effectively supports your activity, allows you to feel good day to day, and doesn’t trigger caloric overcompensation due to persistent hunger.

Mistake: Following unqualified influencers

The ‘diet industry’ is big business. Beware of people trying to sell the latest and greatest diet hack that promises to melt pounds away. If someone guarantees a quick fix through following their rigid rules, or eliminating whole food groups, or having to buy a bunch of specific supplements – I’d encourage you to run fast in the other direction.

There are many good sources of information out there, including advice grounded in evidence-based research and delivered by a qualified professional. The gold standard is working one-on-one with a Registered Dietician (RD). More specifically, an RD familiar with your individual needs as an athlete, your specific preferences, health history, and activity level.

However, even advice that is scientifically correct might not apply to you and your needs. What works for a sedentary individual might not be appropriate for an endurance athlete who trains 5-6 times a week. Similarly, the needs of a professional endurance athlete training 20 or 30+ hours a week would differ from an amateur training only an hour a day. And nutrition guidance changes when fueling endurance sports as opposed to strength, power, and combat sports.

The most effective advice is usually quite practical and very boring: creating long-terms habits you can sustain leads to permanent change.

Weight Loss Mistake: Treating ‘a diet’ as a short-term solution.

‘Diet’ is a 4-letter word as far as I’m concerned. I often hear athletes say they need to “go on a diet to lose weight”. That indicates someone is going to follow a special nutrition routine for a designated period, then stop doing those things once the weight loss goal is achieved.

Many of the named and branded diets (Keto, Low-Carb, Low-Fat, Atkins, Zone, Intermittent Fasting, etc.) work for weight loss, as long as you stick with them. They work because they help create a caloric deficit. As a result, they may result in rapid weight loss, but they are rarely sustainable for athletes. They create unsustainable calorie deficits or are deficient in macronutrients (carbohydrates specifically) needed to perform as an athlete. When athletes stop the diets, they increase calorie consumption to support their activity level, and often overcompensate, and the weight changes reverse.

Instead, I encourage people to create long-term habits that allow their weight to stabilize. Then, think of “dieting” as a focused period when they make minor adjustments to those habits. Your basic everyday habits need to be sustainable and stable, and then if you decide to temporarily lose a small amount of weight for a competition, you can do so within your known habits.

Weight Loss Mistake: An all-or-nothing approach.

Too many get trapped in an all-or-nothing approach to diet and exercise. When they are training consistently, they are committed to good nutrition habits and fueling strategies. During periods when they are busier with work or other life commitments, training consistency declines. So do those good nutrition habits. Of course, good nutrition is important to performance in sport, but eating wholesome and nutritious food is good for overall health and wellness all the time.

That all-or-nothing approach often contributes to caloric imbalances. That can mean a caloric surplus during times of lower activity, which could lead to weight gain. Or, it can mean an unsustainably large caloric deficit at times of higher activity, which could lead to impaired performance or adaptation to training.

The latter is a common occurrence when athletes are starting a new program or a new season. To avoid this trap, please do not completely change what you eat, slash your calories in half, and double your training volume.

  1. This article makes sense about how and when to fuel your body to maximize performance and clarifies some myth about how fat burning works, but it doesn’t say much about quality of nutrition which plays a big part on losing weight or maintaining weight.

  4. Thanks for this great article Renee. I’m fortunate to have had you as my coach for so long and this article is a great example of the practical advice you continuously provide with no sugar coating, that is simple enough for anyone to follow. I will certainly be adding it to my list of the many nuggets of wisdom I have from you – it is one of the key areas that continues to be a struggle for me.

  5. Thanks, Renee. This article explains a lot of what I’ve experienced the last few years as an endurance cyclist. The push for more miles/less calories for weight loss. Then the ‘falling off the wagon’ as my miles drop and calories increase.

  6. Excellent article with the mistakes explained (guilty as charged!)
    Cutting out my nocturnal munching should help and eating smaller more wholesome meals. I also added weight training to build muscle bulk for that off the cycle fat burning. I will see how it works going forward.

  7. I need to print this column and read it periodically to remind myself. I fall into all of these traps and I should know better.

  8. I find much easier to drop weight when I cut the processed sugars and high glycemic index foods except during training. Ice cream is one of my favorite deserts but an apple definitely helps drop weight more than ice cream regardless of my activity.

    1. I agree. When I see that I’m carrying a bit more fat than I want, I increase my focus on eliminating these kinds of carbs. It’s a simple enough strategy that I can do it, which is key. But I will also say that the emotion attached to weight, shape, fat on the body, etc. makes rational decision-making hard. I think I’ve fallen into each of these traps. (I will consume no carbs and go on 75-mile rides, yeah, that’s the ticket!) We live in such an all-or-nothing, magic bullet culture. If I can look at it as moving myself in the direction I prefer, vs. fixing something that’s “wrong”, I’m more consistent and thus more successful.
