This list of zero calorie foods includes foods that you can eat in unlimited quantities, without derailing your weight loss goals.
1. Water
Calories per serving: 0 calories
The only truly zero calorie food on this list, water is essential for your weight loss. Hydration promotes better sleep which helps curb cravings and keeps your body satiated among other benefits we write in our article about ‘Why (and How) You Should Drink a Gallon of Water a Day.’
When dehydration kicks in, your brain can confuse hunger for thirst. If you’re hungry, but it’s not mealtime, reach for a big glass of water instead.
So how much water should you be drinking a day? Here’s our rule of thumb:
Take half your body weight in pounds and drink that many fluid ounces. For example, a 200-pound person should drink 100 fl. oz. of water a day. Some people need more, while some need less, but it’s a good starting point.
2. Vitamins and Supplements
Calories per serving: 0 calories
Your general multi-vitamins do not contain calories. Supplements, like natural powders such as maca or cacao, are typically also low in calories and are effective caffeine alternatives.
One major exception are chia seeds, which are higher in calories (137 calories per ounce), although don’t let that deter you from taking them. They are loaded with fiber. Just schedule it into your targeted daily calories.
3. Lemon or Lime
Calories per serving: 1 calorie per wedge
Lemon and lime can be used in unlimited quantities to brighten up your meals and beverages. They fall into the bucket of zero calorie foods because they more or less have no calories, with one wedge of lemon producing just 1 calorie worth of juice.
Add lemon and lime to your meals (it’s great on both fish and chicken) and your beverages. Nothing is as refreshing as crisp lemon water, which is a popular zero-calorie drink during intermittent fasting during fasting hours.

4. Herbs
Calories per serving: 1 calorie in a small bunch of fresh herbs
Whether it’s a few springs or leaves of fresh thyme or basil, herbs are nearly zero-calorie foods that pack a lot of punch.
Keeping a small herb garden in the kitchen window is one of our favorite reminders to add herbs like basil, mint, oregano, and rosemary to our meals, drinks, shakes, smoothies, and even to our grill embers to smoke our vegetables.
5. Hot Sauce (Tabasco or Mexican Only)
Calories per serving: 1 calorie per teaspoon
Similar to the chilies below, hot sauce, particularly fresh, Mexican-style hot sauces like Cholula and Valentina, are very low in calories.
Hot sauce is a zero calorie food that you can eat in unlimited amounts without it affecting your weight loss.
6. Coffee and Tea
Calories per serving: 2 calories per cup
Outside of added creamer or milk, coffee and tea count as a zero-calorie food and something that many drink while fasting.
Living in Colombia has taught us a lot about coffee, and for best taste and nutrition, we recommend grinding fresh coffee beans and preparing your coffee in a French press.
7. Chiles
Varieties such as jalapeño, ancho, pasilla, guajilla, habanero, etc.
Calories per serving: 2-4 calories per raw chile
After spending a year living in Mexico, chilies became a powerful way to flavor our food in the fewest amount of calories. While the size of chilies of course varies, raw chilies are very low in calories. Add some to your next meal, if you dare!
8. Mustard
Calories per serving: 3 calories in 1 teaspoon or packet
Healthy food doesn’t mean “bland” food. Finding high-quality mustards at a specialty shop is one of our favorite ways to dress up our breakfast eggs and salads.
We always have a jar of this zero calorie food in our refrigerator. This 4-Pack on Amazon is a go-to.
9. Vinegar
Calories per serving: 3-6 calories in 1 tablespoon
Adding vinegar into your cooking, like apple cider, sherry or red wine vinegar, adds depth of flavor into many meat and vegetable dishes. We categorize vinegar as one of our ‘unlimited foods’ for our clients.
One of our favorite ways to use vinegar is our early morning drinks of water (boiled), lemon (1/4 slice), cinnamon (dash), and apple cider vinegar (1 ounce) to aid in digestion.
10. Garlic
Calories per serving: 4 calories per clove
Packed with anti-inflammatories and immunity-boosting benefits, add garlic to your list of nearly zero-calorie foods. At just 4 calories per wedge, load up your meals and dressings.
To capture all the nutritional benefits of this zero calorie food, you have to buy full cloves and mince or chop them just before cooking or eating them.
11. Ginger
Calories per serving: 9 calories per half-inch chunk
Fresh ginger is one of our mainstays. Present in our Asian stir fry, herbal teas, and favorite meal replacement smoothies, ginger also aids in digestion, immunity, and nauseousness.
12. Green Onion
Calories per serving: 10 calories per 1/4 cup
Green onions and scallions qualify under our unlimited, nearly zero-calorie food list with how much taste they add with just a few stalks. Fun fact, you eat the white part of the green onion which has the most flavor. Save the green ends for garnish.
13. Flavor Extracts
Such as pure vanilla, peppermint, and almond.
Calories per serving: 12 calories per teaspoon
Used in baking, smoothies, and homemade granola, load up on flavor extracts like vanilla, peppermint, and almond. We use these extracts when making our Instant Pot granola to manage the amount of sugar and preservatives often found in store-bought brands.
14. Cocoa Powder (Unsweetened)
Calories per serving: 12 calories per tablespoon
Believe it or not, cocoa powder(not to be confused with cacao powder which is raw) has very few calories while still imparting significant health benefits like mood-boosting and antioxidants.
When trying to lose weight and craving dessert, add this zero calorie food to your shake for something sweet.
