Garlic (Allium sativum) is a staple in cuisines worldwide, celebrated for its pungent flavor and health-boosting properties. Beyond its culinary uses, it offers a distinct, low-impact nutritional profile that is valuable for anyone monitoring their macronutrient intake. While it's easy to assume this vegetable is low in calories, a detailed look at the macros for 15g of garlic provides clear data for meal planning.
The Macro Breakdown of 15g of Raw Garlic
According to nutritional data, a 15-gram serving of raw garlic offers a small but notable amount of each primary macronutrient, though it is predominantly composed of carbohydrates. Here is a precise look at its nutritional composition:
- Calories: 22 kcal
- Total Carbohydrates: Approximately 5 grams
- Protein: Approximately 1 gram
- Total Fat: Approximately 0.1 grams
- Dietary Fiber: Approximately 0.3 grams
The vast majority of the calories in garlic come from its carbohydrate content, with a small contribution from protein and almost no fat. The fiber content is minimal but does contribute to the overall nutritional value.
What 15 Grams of Garlic Looks Like
It can be tricky to visualize a 15-gram serving of garlic without a kitchen scale, as garlic clove sizes vary significantly. An average supermarket garlic clove is often estimated to weigh between 5 and 15 grams. Therefore, 15 grams could be:
- A single, very large clove of garlic (especially common in hardneck or elephant varieties).
- Two to three smaller-to-average sized cloves.
For culinary purposes, recipes often call for a specific number of cloves. If you're using larger, specialty varieties, it's wise to use a scale to measure your serving size accurately if strict macro tracking is your goal.
Raw vs. Cooked: Macronutrient Stability vs. Allicin Content
While cooking dramatically affects some of garlic's most celebrated health compounds, its basic macronutrient composition remains relatively stable. Here's a comparison:
| Feature | Raw Garlic (15g) | Cooked Garlic (15g) |
|---|---|---|
| Calories | ~22 kcal | ~20-22 kcal (negligible change) |
| Carbohydrates | ~5g | ~5g (negligible change) |
| Protein | ~1g | ~1g (negligible change) |
| Fat | ~0.1g | ~0.1g (negligible change) |
| Allicin Content | High | Reduced, especially with high heat |
| Flavor Profile | Pungent, sharp | Mellow, sweet, caramelized |
As the table shows, the macros for 15g of garlic are not significantly altered by cooking. The main difference lies in the potent, sulfur-based compound, allicin. Allicin is created when raw garlic is crushed or chopped and is responsible for many of its strongest health benefits, including antibacterial and immune-boosting effects. Heating garlic denatures the enzyme that creates allicin, reducing its potency.
Beyond the Macros: Health Benefits of Garlic
Despite its minimal macronutrient contribution, incorporating 15 grams of garlic into your diet offers a powerful health boost. Many of its benefits are tied to allicin and other antioxidant compounds:
- Immune System Support: Allicin and other compounds possess antibacterial and antiviral properties that help the body fight off illness.
- Cardiovascular Health: Regular consumption of garlic may help lower blood pressure and cholesterol levels, supporting overall heart health.
- Anti-inflammatory Effects: Garlic has been shown to have anti-inflammatory properties, which can help soothe sore joints and muscles.
- Prebiotic Benefits: Garlic contains prebiotic fiber, which nourishes the beneficial bacteria in your gut, supporting a healthy digestive system.
- Rich in Micronutrients: Garlic contains important micronutrients like manganese, vitamin B6, and vitamin C.
How to Incorporate 15g of Garlic into Your Meals
Getting 15 grams of garlic into your daily diet is simple and can add a burst of flavor to many dishes. Here are a few easy ideas:
- For maximum allicin: Mince 1-3 cloves and add them to a salad dressing, pesto, or a simple vinaigrette. For the most benefit, let the crushed garlic sit for 10-15 minutes before adding to a recipe.
- For a milder flavor: Roast a whole head of garlic until soft and caramelized. Squeeze out the creamy, sweet cloves to spread on toast or mix into dips and sauces.
- For daily seasoning: Sauté finely chopped garlic in olive oil and use it as a base for soups, stir-fries, and sauces.
- In marinades: Use crushed garlic in marinades for meat or tofu to infuse deep flavor before cooking.
- In dips: Add minced garlic to hummus, guacamole, or yogurt-based dips for a zesty kick.
Is Garlic Keto-Friendly?
Given its high carbohydrate content by weight, some on a ketogenic or very low-carb diet may wonder if garlic fits their plan. The answer is a resounding yes. Because only a small amount is used to add significant flavor, the total net carb count is very low. For example, a single clove has less than 1 gram of net carbs, which is easily managed within a daily carb limit. Garlic can be a valuable tool for adding depth to low-carb dishes without compromising macro goals.
Conclusion
While it won't be a primary source of macronutrients, knowing what are the macros for 15g of garlic helps confirm its role as a healthy, low-calorie ingredient. A typical 15-gram serving provides approximately 5g carbs, 1g protein, and negligible fat, along with numerous beneficial compounds like allicin. Whether you prefer it raw for maximum health benefits or cooked for a sweeter, milder flavor, garlic is a nutritionally sound choice that adds robust taste to countless dishes.

How to Store and Prepare Garlic
To get the most out of your garlic, store it in a cool, dry, dark, and well-ventilated area. Before use, separate the cloves and peel the papery outer skin. For the strongest flavor and health benefits, crush or mince the garlic and let it sit for a few minutes before cooking to activate the allicin.
How to Avoid Garlic Breath
Chewing fresh parsley, mint, or an apple after eating can help neutralize garlic breath. Some also find drinking a glass of milk can be effective. Using garlic in cooking tends to produce less potent breath than consuming it raw.
Garlic Supplements vs. Fresh Garlic
Garlic supplements exist, but fresh garlic, especially when crushed or chopped and eaten raw, is the most reliable way to consume allicin. Supplements vary in quality and allicin content, and some may cause side effects in sensitive individuals. Always consult a doctor before starting any supplement.
