Ever eat a meal and feel like you could run through a brick wall … only to crash like a toddler missing nap time 30 minutes later?
Yeah, I'm right there with you.
That rollercoaster of energy we're talking about? In many cases, it can come down to what kind of carbs you just ate.
...and no, carbs aren't the enemy. But the type of carb? That's where the magic (or the mayhem) can happen.
Enter: low glycemic foods.
The underrated MVPs of sustained energy, balanced blood sugar, and keeping your cravings in check without living off of just air and ice cubes.

What Is Glycemic Index (GI)?
The glycemic index is a ranking of how quickly your body turns carbs into glucose (aka sugar in the blood).
The scale runs from 0 to 100. It holds pure glucose (the simplest form of carbs), scoring a straight-up 100.
The lower the score, the slower your blood sugar rises, which is what you want in most cases when choosing low glycemic foods.
Here's the quick breakdown:
• Low GI: 55 or less (slow + steady)
• Medium GI: 56–69 (middle of the road)
• High GI: 70+ (fast-acting carbs)
Before moving on, I want to call out something that needs to be said: Is all sugar bad? Absolutely not.
Fructose, glucose, and sucrose are three different types of sugar.
• Fructose has a GI of 23.
• Glucose is 100.
• Sucrose is 65.
Same category, but very different effect when it comes to low glycemic foods.
What Impacts a Food's Glycemic Score?
It's not just the carbs … Sometimes it's how they're packaged.
Here's what affects GI the most...
Type of Carbohydrate: Simple vs Complex
Fiber Content: More fiber = slower absorption
Fat & Protein Content: Slows digestion and sugar release
Processing: More processing = typically higher GI
Ripeness & Cooking Method: Ripe fruit and overcooked pasta? Faster blood sugar spike.
This is why understanding low glycemic foods is so important for maintaining stable energy levels throughout the day.
Why You Should Care About Low-GI Foods
Here's what eating low glycemic foods can do for you:
• Steady energy instead of crashes
• Fewer cravings
• Better blood sugar control (think insulin resistance, PCOS, or diabetes)
• More sustainable fat loss, especially when paired with protein
The beauty of low GI foods is that they work with your body's natural processes instead of against them.
A List of Low-Glycemic Foods To Try
These low glycemic foods digest slowly and won't leave you hangry an hour later:
Carbs
• Oatmeal (not instant)
• Brown rice, barley, quinoa
• Whole grain pasta or tortillas
Fruits
• Berries
• Apple
• Oranges
• Avocados
Legumes
• Lentils
• Black beans
• Chickpeas
Veggies
• Broccoli
• Bell peppers
• Spinach
• Asparagus
Protein
• Eggs
• Chicken
• Turkey
• Lean beef
• Fish
• Greek yogurt
• Cottage cheese
Pro Tip: Pair carbs with a fat or protein (like toast + eggs or rice + chicken) for an even better blood sugar response. This is one of the best strategies for maximizing the benefits of low glycemic foods.
But Wait … Are High-GI Foods Always Bad?
Nope. In fact, they can be a game changer after your workouts.
After intense training, your muscles need to refuel, and they need to refuel fast.
This is the one time that I recommend that you have a quick sugar spike. Pairing a high-glycemic carb with a fast-digesting protein can help support quicker recovery and glycogen replenishment.
So if you're looking to improve your recovery and manage your soreness, then they can be very useful.
In fact, I use a post-workout glucose and a whey protein isolate after every single resistance training session that I do!
But for the other 90% of your meals? Stick with low glycemic foods for sustained energy and better results.
Comprehensive Low-Glycemic Foods FAQ
Q: What Are the Best Low-Glycemic Foods for Diabetics?
A: The best low glycemic foods for diabetics include non-starchy vegetables (broccoli, spinach, bell peppers), lean proteins (chicken, fish, eggs), legumes (lentils, black beans), and whole grains (oats, quinoa, brown rice). These low GI foods help maintain stable blood sugar levels and reduce insulin spikes.
Q: How Do Low-Glycemic Foods Help with Weight Loss?
A: Low glycemic foods help with weight loss in several ways. They can help you feel full for longer, reduce cravings, prevent energy crashes, and help your body burn fat more efficiently. When your blood sugar stays stable, your body doesn't store as much fat. You're also less likely to experience the hunger that comes with blood sugar crashes.
Q: What’s the Difference between Low and High Glycemic Foods?
A: Low glycemic foods (GI 55 or less) are digested slowly and cause a gradual rise in blood sugar. High glycemic foods (GI 70+) are digested quickly and cause rapid blood sugar spikes. Low GI foods provide sustained energy, while high GI foods give quick energy followed by crashes. Think oatmeal vs. white bread.
Q: Can I Eat Low-Glycemic Foods If I’m Not Diabetic?
A: Absolutely! Low glycemic foods benefit everyone, not just diabetics. They can help maintain steady energy levels, reduce cravings, support weight management, and may reduce the risk of developing type 2 diabetes. Most people feel better and have more consistent energy when they focus on low GI foods.
Q: What Are Some Easy Low-Glycemic Food Swaps?
A: Here are simple low-glycemic foods swaps:
High GI | Low GI Swap |
---|---|
White rice | Brown rice or quinoa |
White bread | Whole grain bread |
Instant oatmeal | Steel-cut oats |
White pasta | Whole grain pasta |
Sugary cereals | Plain Greek yogurt with berries |
White potatoes | Sweet potatoes |
These swaps can help you enjoy similar foods with better blood sugar control.
Q: Do Low-Glycemic Foods Taste Bland?
A: Not at all! Many delicious foods are naturally low glycemic foods. Think avocados, berries, nuts, lean meats, and vegetables. The key is learning how to season and prepare them well.
Q: How Quickly Do Low-Glycemic Foods Affect Blood Sugar?
A: Low glycemic foods typically cause blood sugar to rise gradually over 1-3 hours, compared to high GI foods that spike blood sugar within 15-30 minutes. This slower response is exactly what makes low GI foods so beneficial for sustained energy and appetite control.
Q: Can I Combine Low and High-Glycemic Foods in the Same Meal?
A: Yes! Adding low glycemic foods like protein, healthy fats, or fiber to a meal with higher GI foods can actually lower the overall glycemic response. For example, adding nuts to fruit or eating protein with rice can help moderate blood sugar spikes.
Q: Are All Fruits High Glycemic?
A: No! Many fruits are actually low glycemic foods. Berries, apples, oranges, pears, and cherries are all low GI. Even some tropical fruits like grapefruit are low glycemic. The key is choosing whole fruits over fruit juices and being mindful of portion sizes.
Q: How Do I Know If a Food Is Low Glycemic?
A: Look for low glycemic foods that are high in fiber, protein, or healthy fats. Generally, whole, unprocessed foods tend to be lower GI. You can also check glycemic index databases online or look for foods labeled as "low GI." When in doubt, pair any carb with protein or fat to lower its glycemic impact.
Q: Should I Only Eat Low-Glycemic Foods?
A: While low glycemic foods should make up the majority of your diet, you don't need to be 100% strict. The key is balance and timing. Focus on low GI foods for most meals, but don't stress about the occasional higher GI food, especially around workouts when your body can use that quick energy.
Q: Do Low-Glycemic Foods Help with Energy Levels?
A: Yes! Low glycemic foods provide more sustained energy compared to high GI foods. Instead of the energy rollercoaster of spikes and crashes, low GI foods give you steady, consistent energy throughout the day. This is why many people report feeling more energetic and focused when they switch to eating more low glycemic foods.
Using Low GI Foods to Reach Your Goals
Low glycemic foods aren't a fad … they're a strategy. They help you stay energized, keep your blood sugar steady, and support your goals without cutting carbs out.
...and when you know how to time your higher-glycemic foods? That's when you start fueling for performance.
The beauty of focusing on low GI foods is that it's not about restriction. It's about making smarter choices that help you feel better and perform better.
