Whiskey Calories

Whiskey is a low calorie alcoholic drink.

A 1-oz serving of whiskey contains about 70 calories.

Drinking several glasses of whiskey each day can increase the number of calories a person consumes, potentially leading to weight gain.

Weight Gain

Weight gain may increase the risk of diabetes complications.

There is evidence that long-term alcohol consumption correlates with a higher risk of diabetes complications.

It can also cause dangerously low blood sugar and harmful acids to build up in the blood.

Alcohol and blood sugar 

Avoid drinking alcohol if your blood sugars are uncontrolled.

Whiskey and other alcohols may increase the risk of dangerously low blood sugar.

The risk of low glucose (alcohol-related) is higher when you:

  • drink on an empty stomach
  • replace a meal with alcohol
  • take diabetes medication or insulin
  • drink to excess

It takes approximately 1 to 1.5 hours for your liver to break down alcohol from one drink. Low blood glucose persists until the body metabolizes the alcohol.

Drinking Tips for Diabetics

The Centers for Disease Control and Prevention (CDC) recommends the following drinking tips for people with diabetes:

  • Avoiding drinking on an empty stomach
  • Eat food with your alcohol
  • Avoiding drinking if blood glucose is not well-controlled
  • Avoid drinking if you have a history of negative reactions to alcohol
  • Stop drinking after 1-2 drinks
  • Don’t exercise while drinking. Exercise lowers blood sugar.

Emergency assistance is required if the person experiences symptoms of low blood glucose, such as fainting.

The Best Alcoholic Drinks for Diabetics

Here are the most appropriate alcoholic drinks for people with diabetes, based on carbohydrate content.

Straight Distilled spirits

Distilled spirits contain few to no carbs.

  • Whiskey, vodka, gin, tequila, or rum: Contain 0 grams of carbs per 1.5-ounce.


There is a potential for hypoglycemia due to your liver not being able to maintain basal blood sugar levels while metabolizing alcohol. This can cause dangerously low blood sugar — especially if you drink on an empty stomach

Avoid mixing with sugary juices, soda, or garnishes. This can cause blood sugar levels to spike and subsequently dip to dangerously low levels.

Champagne & Wine

  • Dry Champagne: Brut and extra-brut champagne have less than 1.7 grams and 0.8 grams of carbs, respectively, per 5 ounce serving.
  • Red wine: Contains only 3.8 grams of carbs per 5 ounce serving.
  • White wine: Provides only 3.8 grams of carbs per 5 ounce serving.

Lite Beer

Low carb beer is a better option for people with diabetes who want to enjoy an occasional cold brew.

  • Miller Lite: Provides only 3.2 grams of carbs in a standard 12 ounce serving.
  • Coors Light: Contains just 5 grams of carbs per 12 ounce serving.
  • Bud Lite: Has fewer than 5 grams of carbs per 12 ounce serving.

Drinks that People with Diabetes Should Avoid

While there are some diabetes-friendly cocktails, most cocktails are mixed with juices, sodas, syrups, and/or garnishes that add sugar.

Diabetics should avoid cocktails with added sugars such as:

  • Margaritas, piña coladas, and daiquiris
  • Dessert wines, such as vermouth, port, and sherry, are high in carbs
  • Cream liqueurs such as Bailey’s Irish Cream and Kahlua

Important tips: Do not drink on an empty stomach. Avoid drinking with low blood sugar. Monitor your blood sugar before, during, and after drinking.
