Keto Diet Basics: Why Labels Matter
The keto diet is a high-fat, moderate-protein, and low-carbohydrate eating plan designed to shift your body into a state of ketosis. To maintain ketosis, you typically need to consume fewer than 20 to 50 grams of net carbohydrates per day.
However, not all carbohydrates are easily detectable; some can be hidden in unexpected places, such as sauces, dressings, and even snacks that are marketed as "healthy." This is why it is important to read labels carefully.
Key Things to Check on Nutrition Labels
Food packaging is designed to sell, not inform. Words like "keto-friendly" or "low-carb" can be misleading. To stay truly on track, you need to understand the nutrition facts panel and ingredient list.
Net Carbs vs Total Carbs
One of the biggest misconceptions about the keto diet is confusing net carbs with total carbs.
Net carbs= Total Carbs-Fiber-Sugar Alcohol
Things to carefully consider:
Hidden Ingredients That Can Kick You Out of Ketosis
Even foods labeled “low carb” may contain non-keto ingredients. Watch out for:
Some studies suggest that sucralose and similar non-nutritive sweeteners may change the gut microbiome in some individuals, but effects vary based on dosage, frequency, and personal biology. While some may experience digestive changes, others may not notice any impact. More research is needed to understand the long-term implications.
Tip: If you can’t pronounce it or it sounds like a chemical, look it up before eating it.
Keto-Friendly Nutrients to Look For
You should look for the following things on a keto label:
Go for nutrient-dense, whole-food-based products with a short ingredient list and recognizable ingredients.
Sample Food Label Walkthrough
You can put your label-reading skills into practice with a real-world example: a popular keto protein bar.
Example Label:
At first glance, this product appears appealing with only 2g of net carbs. However, the nutrition label doesn't provide the full picture. It's important to check the ingredient list as well. Despite the low net carb count, ingredients like maltodextrin, soluble corn fiber, or sucralose could still cause increased blood sugar levels.
Additionally, be aware of the serving size; some packages may contain two servings, which means consuming the entire product could double your intake.
Final Thoughts
Understanding how to read nutrition labels is a valuable skill that can help you maintain ketosis and make informed food choices. Avoid relying solely on marketing phrases like “keto-friendly”; instead, always check the ingredient list and calculate net carbs yourself.
Be cautious of hidden sugars and high-glycemic fillers, such as maltodextrin or corn syrup solids, as these can disrupt your ketosis. Instead, choose products rich in healthy fats, electrolytes, and clean protein, with simple and recognizable ingredients.
Many tracking apps can simplify this process by allowing you to scan barcodes and effectively track your macros. With practice, interpreting labels will become easier, giving you greater control, reducing unexpected outcomes, and leading to better results.
