Parenthood as an Endurance Sport: How to Fuel for Daily Life, Family, and Performance

Last Updated: July 14, 2025

As a new mom, I have a great appreciation for the endurance event that is parenthood! Whether you are a breastfeeding mom, a stay-at-home primary caregiver, or a full-time working dad, the demands parenthood places on your brain and body are nutritionally demanding.

When I recently became a new mom, I was shocked by how physically and mentally demanding motherhood is. Between breastfeeding my baby every 2-3 hours (and burning somewhere around 500 extra calories per day in the process!), running around all day tending to his needs, juggling new appointments with various healthcare providers, caring for our dog, and tending to household tasks and my marriage – I found myself utterly exhausted at the end of each day. And this was before I returned to my full-time job! 

As a functional nutritionist, I started to realize that parenting isn’t just an emotional journey—it’s a full-on endurance event. Much like training, parenthood places significant nutritional demands on the body due to the combination of physical and psychological demands it entails. (Source, Source, Source

Parenthood is the ultimate endurance event because it doesn’t end after a couple of hours, days, or weeks – it continues for years!

Many of my clients are parents who want to PR their next trail half-marathon, finish the Leadville Trail 100 MTB, or complete multiple climbing projects. This takes the endurance event that is parenthood up a notch, to say the least! They want nutrition care that supports their energy and health so they can show up fully for their families and in their professional and sporting lives.

In this blog, I’ll discuss the nutritional demands of parenthood, how these demands are increased when parents are also athletes, and how a comprehensive performance nutrition approach can help active parents thrive. 

The Nutritional Demands of Parenthood

We don’t often think of parenthood as “physical activity,” but for many parents, it is! Whether you are a stay-at-home mom caring for your baby all day, a parent constantly chasing after your active toddler, or working parents juggling car pools and all the household tasks involved with caring for kids and teenagers, parenthood is an active time for many!

The cognitive load of juggling work, a household, and children places significant demands on your brain. Your brain is a major consumer of calories, gobbling up about 20% of your daily energy (calorie) requirement! (Source

In addition, the sleep deprivation that often accompanies parenthood, at least in the early days, necessitates more food intake to keep you awake. (Source) And then, of course, the mental and emotional stress associated with caring for children may deplete B vitamins and magnesium, among other nutrients. (Source)

If you are a breastfeeding mother, your body is already burning about 500 calories more per day than it does at baseline. (Source) This calorie burn is basically equivalent to running five-6 miles a day!

Fueling Properly When Parents Are Also Athletes

I work with many active parents ranging from a high-level climber who has a young child and works full-time to a day training for long-distance mountain bike races. These individuals are ambitious athletes AND don’t want to compromise their personal or professional lives. 

When parents are also outdoor athletes, their fueling needs are increased further! Training, recovery, and racing expend a lot of calories. Individual calorie burn varies from one athlete to the next. If you’re curious, you can estimate the amount of calories you burn during physical activity with the total daily energy expenditure equation.

Total energy expenditure is calculated as follows:

TEE = BMR + TEF + SPA + TEA

  • TEE = total energy expenditure
  • BMR = basal metabolic rate (such as the Harris-Benedict equation)
  • TEF = thermic effect of food (can use a TEF online calculator)
  • SPA = spontaneous physical activity (% of RMR)
  • TEA = thermic effect of activity

To calculate TEA and SPA, you’ll need to look up energy expenditure tables online. Alternatively, a functional nutritionist can use activity tables to calculate your estimated TEA and SPA. 

While the TEE calculation isn’t perfect because people’s individual calorie burn varies based on other factors, including their hormone status, it is a good starting point for ascertaining your unique calorie needs. 

Here’s the problem many active parents face – they don’t know how to properly fuel their bodies to meet the dual demands of life and training. They’re doing things like fasted training, cutting calories, and skipping meals, which can lead to fatigue, irritability, brain fog, non-restorative sleep, and compromised athletic performance and recovery, among other symptoms.

A few quick nutrition tips for active parents:

  • Don’t skip breakfast! Breakfast may be the most important meal of the day for athletes and parents, although lunch, dinner, and thoughtful snacks are also vital. Eating a balanced breakfast sets the tone for healthy blood sugar control, energy, and stamina throughout the day.
  • Remember that quantity AND quality matter. As an active parent, you must eat enough to support the demands of daily life and training. Avoiding low energy availability, which can significantly impact your health, performance, and recovery, is essential. However, we simultaneously want to prioritize high-quality, nutrient-dense foods that will nourish our bodies and brains – think: high-quality protein (pastured, organic, and/or wild-caught, if possible), starchy tubers like potatoes and sweet potatoes, root vegetables, legumes, whole grains, nuts and seeds, organic dairy products, and olive oil, to name some example foods. 
  • Plan your meals. Always winging it with your meals is a recipe for inconsistent blood sugar and energy levels, leading to fluctuating motivation, performance, and recovery. A little bit of meal planning can go a long way towards reaching your health and performance goals. 

I delve into these strategies and many more with my clients who are active parents.

It can be downright challenging to train for a climb, marathon, or mountaineering trip while parenting. However, as many of my clients have discovered, with dedication, a solid training plan, and a comprehensive nutrition plan, you can not only complete that climb, race, or expedition, but do so with flying colors!

Performance and parenting are not mutually exclusive. With the proper support, you can achieve your performance goals and be fully present in all aspects of your life, including parenting.
