How many carbs in a sugar free vanilla latte Starbucks?

Starbucks is one of the most popular coffee chains, known for its wide variety of coffee drinks and menu items. Many Starbucks customers enjoy ordering lattes, especially flavored lattes like the sugar free vanilla latte. For people watching their carbohydrate or sugar intake, the sugar free vanilla latte seems like a good low carb option. But exactly how many carbs are in a Starbucks sugar free vanilla latte?

In this comprehensive guide, we will break down the nutritional information and carb content of a Starbucks sugar free vanilla latte. We will look at the different sizes, recipes, and customization options that affect the carb count. Whether you are on a low carb, keto, or diabetic diet, this guide will help you determine if a sugar free vanilla latte fits into your nutritional plan.

Nutrition Information for Starbucks Sugar Free Vanilla Latte

Starbucks provides the complete nutrition facts and ingredients for all of their menu items online. This makes it easy for customers to look up carb counts and other nutrition stats.

Here is the basic nutrition information for a Grande (16 oz) hot sugar free vanilla latte made with nonfat milk from Starbucks:

Calories 100
Fat 2.5g
Carbs 9g
Protein 10g
Sugars 0g

As you can see, a grande sugar free vanilla latte has 100 calories and 9 grams of net carbs. It also contains 10 grams of protein from the nonfat milk. Since it is sugar free, there are 0 grams of sugar.


The 9 net carb grams come from three main components of the drink: the coffee, the nonfat milk, and the sugar free vanilla syrup.

A grande coffee at Starbucks has less than 5 calories and 0g carbs on its own. So the coffee itself does not contribute any significant carbs.

Nonfat milk

The nonfat milk provides some natural sugars in the form of lactose, which contributes to the carb count. For one grande latte, Starbucks uses about 8 ounces of nonfat milk. 8 ounces of nonfat milk contains about 9g of carbs from the lactose.

Sugar free vanilla syrup

The sugar free vanilla syrup is proprietary to Starbucks, so the exact carb count is unknown. However, most sugar free syrups contain less than 1g of carbs per serving. So the syrup likely adds only a negligible amount of carbs to the drink.

How Size Affects Carb Count

The carb count listed above is specifically for a grande (16 oz) sugar free vanilla latte. But Starbucks offers this drink in several sizes:

Size Carb Grams
Tall (12 oz) 7g
Grande (16 oz) 9g
Venti (20 oz) 11g

As you can see, the carb count scales up slightly with the larger sizes since they contain more milk. But even a large venti still only has 11g net carbs, which is quite low.

Customizations That Affect Carbs

When ordering a sugar free vanilla latte from Starbucks, there are some customization options that can alter the carb count:

Milk Type

The milk provides most of the carbs, so switching the type of milk will change the numbers:

– Nonfat milk: 9g carbs (grande)
– 2% reduced fat: 12g carbs (grande)
– Soy milk: 14g carbs (grande)
– Coconut milk: 5g carbs (grande)
– Almond milk: 7g carbs (grande)

Soy and 2% milk increase carbs, while coconut and almond milk reduce carbs. Sticking with nonfat is your best bet for lowest carbs.


Adding any additional flavored syrups will raise the carb count slightly. Most sugar free syrups have <1g carbs per pump. So adding 2-3 extra pumps would increase carbs by 2-3g.

Whipped Cream

Whipped cream tops off the latte nicely but does add about 3g net carbs per serving. Skip the whipped cream if limiting carbs.


Since the vanilla latte is already sugar free, any added sweeteners are unnecessary. Stick to the standard recipe without adding sugar, honey, or other high-carb sweeteners.

Is it Keto-Friendly?

One of the most common questions about Starbucks sugar free vanilla lattes is whether they can be part of a ketogenic or very low carb diet. To stay in ketosis, keto dieters must restrict net carbs to 20-50g per day.

An unmodified grande sugar free vanilla latte comes in at just 9g net carbs. This fits easily into a daily keto limit, leaving plenty of carbs leftover for other foods. A venti latte would utilize 11g carbs, also reasonable for keto.

With smart customizations like coconut milk or avoiding whipped cream, you could get the carb count even lower. Overall, a Starbucks sugar free vanilla latte can definitely fit into a keto diet when consumed in moderation. It’s one of the lowest carb selections at Starbucks.

Diabetes Considerations

For people with diabetes monitoring their blood sugar levels, a sugar free vanilla latte is a better choice than a full-sugar version. However, it still contains carbs that can impact blood glucose. The American Diabetes Association recommends spacing carb intake evenly throughout the day, and limiting carb-heavy drinks.

Have your latte with a lower carb breakfast or snack to help control your blood sugar response. Aim to consume lattes only occasionally as a special treat, not daily. And monitor your blood sugar after drinking to learn how your body responds. Be sure to take any insulin that is needed to cover the carbs.

Low Carb Diet Tips

If you are limiting carbs for weight loss, diabetes, or ketosis, here are some helpful tips for enjoying Starbucks lattes on your diet:

– Choose sugar free syrups only
– Opt for the smallest size that satisfies you
– Pick nonfat or coconut milk to reduce carbs
– Skip whipped cream, sugary toppings, and extra syrup pumps
– Balance carb intake at other meals when you have a latte
– Limit yourself to an occasional latte, not daily
– Monitor blood sugar and ketone levels when drinking lattes
– Supplement with fat, protein, and fiber to help manage hunger and blood sugar

Other Low Carb Starbucks Drinks

The sugar free vanilla latte is one of the best low carb options at Starbucks, but not the only one. Here are a few other drinks under 10g net carbs:

Brewed coffee 0g carbs
Cold brew with nonfat milk 3g carbs (grande)
Sugar free cinnamon dolce latte 9g carbs (grande)
Americano 0g carbs
Tea, unsweetened 0g carbs
Sugar free mocha 13g carbs (grande)

Stick to simple coffee, tea, and sugar free lattes to keep your Starbucks orders low in carbs. Avoid frappuccinos, macchiatos, and creamy blended coffee drinks that are much higher in carbs.

Low Carb Starbucks Breakfast

Starbucks also offers some convenient low carb breakfast options:

– Bacon, Gouda, and egg breakfast sandwich (no muffin or bread)
– Sous vide egg bites with bacon or sausage
– Greek yogurt with nuts and cinnamon
– Hardboiled eggs
– Turkey bacon or sausage breakfast sandwich (no muffin)

Pairing a sugar free latte with a low carb breakfast sandwich or eggs is a great way to stay satisfied while limiting carbs.

Should You Drink Sugar Free Lattes?

Sugar free vanilla lattes can be enjoyed in moderation on a low carb diet. But there are some drawbacks to consider:

Blood Sugar Impact

Even without sugar, the carbohydrates in milk can impact blood sugar and require insulin. Frequent consumption may contribute to insulin resistance.

Artificial Sweeteners

Sugar free syrups contain artificial sweeteners like sucralose or aspartame. These may negatively impact gut bacteria and promote cravings.

Caffeine Content

Lattes provide a large dose of caffeine, which can cause jitters and anxiety in caffeine-sensitive individuals.

Non-Dairy Alternatives

While non-dairy milks like coconut and almond milk are lower in carbs, they are highly processed and may contain unwanted additives.


Purchasing lattes daily can get very expensive compared to making your own coffee.

For maximal health benefits, limit sugar free lattes to an occasional treat in moderation. Focus on getting nutrients from whole, unprocessed foods as often as possible. But the right sugar free latte now and then can be part of an overall balanced low carb diet.


A Starbucks sugar free vanilla latte containing 9-11 grams of net carbs (depending on size) can fit into a keto, low carb, or diabetic diet when consumed occasionally. Size down, opt for nonfat milk, skip whipped cream, and avoid added syrups to minimize carbs. Balance the latte with low carb foods for the rest of your meals. While not an everyday drink, treating yourself to a sugar free vanilla latte is certainly possible without sabotaging your nutritional goals. Just be mindful of your portion size, additions, and frequency of consumption.
