On this post, let’s break down food labels in a way that makes sense for your low-carb journey. It’s easy to get tripped up by hidden carbs in packaged foods, and that can slow your progress.
But don’t worry—understanding nutrition labels isn’t as complicated as it seems. With the right approach, you’ll learn to spot misleading claims, identify important numbers, and choose the best options for your goals.
Regardless of the context, a quick guide for better decision-making will encourage you.
Understand Serving Sizes First
Food labels list nutrition facts based on a specific serving size, which may not match what you actually eat. If a product says 10 grams of carbs per serving but contains multiple servings per package, those carbs add up fast. Always check the number of servings per container.
Multiply the carbs in one serving by how many servings you eat to get the real total. Misreading serving sizes leads to eating more carbs than planned, so be mindful of portion sizes.
Even seemingly small differences in serving sizes can add up over time, making it crucial to double-check before assuming a product fits your low-carb diet.
Focus On Total Carbs, Not Just Net Carbs
Many low-carb eaters look at net carbs, which subtract fiber and sugar alcohols from total carbs. While this method can work, it’s not always reliable.
Some sugar alcohols like maltitol still raise blood sugar. Instead of relying only on net carbs, check the total carbs listed on the label. If a product claims to be low in net carbs but has a high total carb count, be cautious.
This is especially important for packaged snacks and keto-friendly products. Remember, different people process sugar alcohols differently, so tracking total carbs gives a clearer picture of what you’re eating.
Identify Hidden Sugars
Sugar comes in many forms, and manufacturers often use tricky names to disguise it. Look for ingredients like dextrose, fructose, maltodextrin, and corn syrup.
Even “healthy” sugars like honey, agave, and coconut sugar impact blood sugar levels. The lower an ingredient appears on the list, the less of it is in the product.
However, companies sometimes use multiple types of sugar to avoid listing one at the top. Always scan the ingredients list carefully to catch these hidden sources of carbs.
If you see multiple types of sugar in the ingredients, the product likely contains more sugar than it appears at first glance.
Check The Fiber Content
Fiber helps slow digestion and has little impact on blood sugar. Foods high in fiber are often good choices for low-carb eaters.
However, some products inflate their fiber numbers to make net carbs look lower. If you see unusually high fiber in a processed product, check the ingredients. Some added fibers, like chicory root or tapioca fiber, can still cause blood sugar spikes.
Whole foods like vegetables, nuts, and seeds provide better sources of fiber without unexpected effects.
Additionally, insoluble fiber passes through the body undigested, while soluble fiber may still have some effect on blood sugar.
Watch Out For Sugar Alcohols And Artificial Sweeteners
Sugar alcohols like erythritol and xylitol are popular in low-carb products, but not all work the same way. Some, like maltitol, raise blood sugar almost as much as regular sugar.
If a product contains sugar alcohols, check the type used. Erythritol and allulose are better options since they don’t significantly affect blood sugar.
Artificial sweeteners like aspartame and sucralose don’t have carbs, but they may cause cravings and digestive issues.
Choose natural options like stevia or monk fruit when possible. Keep in mind that individual responses vary, so monitoring how your body reacts is key.
Avoid Unnecessary Additives
Many packaged foods contain fillers, preservatives, and artificial ingredients that don’t support a healthy low-carb lifestyle.
Common additives like modified food starch, maltodextrin, and hydrogenated oils can increase carb counts or cause inflammation. Stick to foods with simple ingredient lists.
If you can’t pronounce an ingredient or don’t know what it is, it’s best to skip that product. Whole, minimally processed foods are always a safer choice.
Also, some preservatives may not directly add carbs but can still impact gut health and digestion.
Compare Similar Products
Two products that seem identical can have very different nutrition profiles. Always compare labels before choosing. One brand of almond butter might have added sugar, while another contains only almonds and salt. Salad dressings, sauces, and condiments often hide sugar and extra carbs.
Don’t assume that all versions of a product are equally low-carb. Read the labels side by side and pick the one with fewer carbs and cleaner ingredients.
Even the same product from different brands can have huge differences in sugar content, making label comparison a must.
Be Skeptical Of “Healthy” Marketing Claims
Terms like “low-carb,” “keto-friendly,” and “no added sugar” don’t always mean a product is truly low in carbs. Some brands use these labels to attract buyers while still containing hidden carbs.
Always verify the actual nutrition facts and ingredient list instead of trusting front-of-package claims. If a product seems too good to be true, it probably is.
Rely on facts, not marketing, when making food choices. Marketing buzzwords often distract from real nutritional facts, so always flip the package and read the details yourself.
Spot The Hidden Carbs In Common Foods
Even foods that seem low in carbs can have unexpected sugar or starch. Flavored yogurt, protein bars, and even some deli meats contain added sugars.
Pre-shredded cheese often includes potato starch to prevent clumping. Sauces and condiments like ketchup and BBQ sauce are loaded with sugar unless you buy a no-sugar-added version.
Always check the label, even on foods you assume are safe. Even “healthy” foods like granola and nut butters can have hidden sugars that add up over time.
Plan Ahead And Choose Wisely
Reading labels gets easier with practice. Once you identify the best low-carb products, grocery shopping becomes faster.
Keep a list of trusted brands to make decisions easier. When in doubt, choose whole foods like fresh meats, vegetables, and healthy fats, which don’t require labels.
The more whole foods you eat, the less time you’ll spend decoding nutrition facts. Learning your go-to safe options makes meal planning much smoother and helps you stick to your low-carb goals.
Final Thoughts
