Garlic (Allium sativum) is a staple seasoning in cuisines worldwide, celebrated for its pungent flavor and potential health benefits. When considering the nutritional content of garlic, it's important to differentiate between its high concentration of flavor and its very modest macronutrient load. The macros of garlic consist mainly of carbohydrates, with only trace amounts of protein and virtually no fat, especially when eaten in typical portion sizes like a single clove.
The Macronutrient Profile of a Single Clove
For most home cooks and health enthusiasts, the nutrient information for a single clove is the most practical. According to USDA data, a standard raw clove of garlic, weighing around 3 grams, provides a very small number of calories and macros.
- Carbohydrates: A single clove contains about 1 gram of carbohydrates. A portion of this is dietary fiber, which aids in digestion and does not raise blood sugar levels.
- Protein: The protein content is minimal, with a typical clove offering only about 0.2 grams.
- Fat: Fat content is virtually non-existent, at approximately 0.05 grams per clove.
Because a clove is such a small portion, garlic is considered an excellent low-carb, low-calorie way to boost the flavor of meals without affecting dietary goals.
A Detailed Look at 100 Grams of Garlic
While rarely consumed in such large quantities, examining the macros for 100 grams provides a clearer picture of garlic's overall composition. This larger serving size allows for a more detailed comparison of macronutrient densities across different foods. Per 100 grams, raw garlic contains approximately:
- Calories: 149 kcal
- Carbohydrates: 33 grams
- Protein: 6.4 grams
- Fat: 0.5 grams
This breakdown further reinforces that garlic's macronutrient profile is dominated by carbohydrates. The minimal fat and moderate protein content only become apparent in very large serving sizes.
Raw vs. Cooked Garlic Macros
Cooking garlic alters its chemical composition, most notably by reducing the concentration of allicin, the sulfur compound responsible for its pungent odor and many of its reported health benefits. However, the effect on macronutrients is more subtle. The primary change comes from water loss during cooking, which concentrates the macros per unit of weight. For instance, sautéed garlic will have a slightly higher calorie and carb count per gram than raw garlic, not because new macros are added (unless cooked in oil), but because moisture has evaporated.
Below is a comparison of the macronutrient content per 100g of raw versus sautéed garlic, based on average values:
| Nutrient | Raw Garlic (per 100g) | Sautéed Garlic (per 100g) |
|---|---|---|
| Energy | 149 kcal | ~130 kcal |
| Carbohydrates | 33 g | ~22 g |
| Protein | 6.4 g | ~6 g |
| Total Fat | 0.5 g | ~0.4 g |
Note: Sautéed garlic macros may vary significantly based on cooking method and added fats.
The Impact of Allicin
While macronutrients are important, garlic's unique health properties come from its active compounds. Allicin is an unstable compound that forms when garlic is crushed, chopped, or chewed, and it has been studied for its potential to support heart health and immune function. To maximize allicin content, some experts suggest letting chopped garlic sit for a few minutes before cooking to allow the compound to form. High heat can destroy allicin, but cooked garlic still retains many other nutrients, including vitamins and minerals.

Conclusion
In summary, the macros of garlic are modest, primarily consisting of carbohydrates, with a small amount of protein and minimal fat. Whether consumed raw or cooked, it provides a concentrated source of flavor and nutrients for very few calories. This makes garlic a powerful ingredient for those on a variety of diets, including low-carb and ketogenic plans. The key to leveraging garlic's full nutritional potential, including its bioactive compounds like allicin, lies in mindful preparation and not relying on it as a primary source of macronutrients.
