Snack Smarter: Choosing the Right Fuel for Your Activity

By Clint Cullins, RDN, LDN and Diabetes Educator

So, there you are…standing in the kitchen, staring into the fridge and cupboards after crushing your workout and making healthier choices. You’re on a roll—until the highly processed, convenient snacks start staring back at you like puppies at a pet store. Suddenly, choosing a snack feels harder than it should. You’ve learned that food is fuel, but with social media, the internet, friends, family, and even healthcare professionals all offering different advice, how do you know what’s actually “healthy”?
Here’s the kicker: there is no one right answer. You get to decide how to fuel your body.
The best snack is one that fits your health goals, preferences, activity level, and specific needs. You do not have to eat raw broccoli and hummus just because someone on the internet said so. Nutrition is personal. Your age, height, medical needs, activity level, access to food, and culture all influence what works for you.
In general, it’s important to focus on nutrient density when making snack choices. Nutrient dense foods are lower in calories per serving, are often less processed and contain higher levels of nutrients per serving vs a highly processed snack which tends to be high in calories but low in valuable nutrients. The goal here is to supply the body with the materials it needs to sustain our activity, help us recover, and replenish nutrients that may have been used during our activity.
So before grabbing a snack, ask yourself two questions:
1. What level of activity am I about to do?
2. Why am I eating this snack?
Then use these general guidelines to help point you in the right direction.
Low-Intensity Activity
Think household chores, gardening, yoga, or a short walk. You generally don’t need extra fuel for these activities because your body has plenty of stored energy available. But if your next meal is still a few hours away, a small snack can certainly fit the bill.
Focus on fiber, healthy fats, and a little protein.
Try:
• Low-fat Greek yogurt with berries
• A small handful of nuts
• Raw vegetables with hummus
Moderate-Intensity Activity
Swimming, dancing, sports, or brisk walking may benefit from a pre- or post-workout snack, especially if your last meal was a while ago.
For pre-workout, focus on easily digested carbohydrates with a little protein. Keep protein and fiber moderate to avoid turning your workout into an unfortunate stomach adventure.
Try:
• A small apple with 1 tablespoon peanut butter
• Two rice cakes with a thin layer of almond butter and honey
For post-workout, pair carbohydrates with more protein to help replenish energy and support recovery.
Try:
• Oatmeal made with low-fat milk and ½–1 scoop of protein powder
• A cup of chocolate milk
• A hard-boiled egg with a piece of fruit
High-Intensity or Endurance Activity
Activities lasting longer than 60 minutes—think long trail hikes, endurance events, or trekking through rugged terrain—require more intentional fueling and usually aren’t relevant to the average person.
These activities often require quick-digesting carbohydrates before and during exercise. Afterward, aim to refuel within about 45 minutes with a carbohydrate-rich snack that also includes protein, often using a 4:1 carbohydrate-to-protein ratio as a general guideline.
The Bottom Line
Healthy snacking doesn’t have to be complicated, perfect, or involve a vegetable you secretly hate.
Think about what your body is doing, what it needs, and what you actually enjoy eating. Choose foods that support your goals, keep you fueled, and fit into your overall eating pattern.
Because the best snack isn’t the one with the healthiest reputation—it’s the one that works for you.
