Can I have 0 calorie drinks while fasting? Yes, you can drink most zero calorie drinks while fasting, and they won’t break your fast. Your body needs zero calories to burn fat during fasting periods, and drinks with no calories keep you in that fat burning state.
What drinks can I have during my fasting window?
Water tops the list. Plain water has zero calories and zero sugar, so drink as much as you want. Your body burns fat when you fast, and water helps this process.
Black coffee works too. A cup of black coffee has less than 5 calories. Studies show black coffee can boost your metabolism by 3 to 11 percent. Just skip the milk, cream, and sugar. These add calories and stop your body from burning fat.
Tea is another good option. Green tea, black tea, and herbal teas all have zero calories when you drink them plain. Green tea has compounds called catechins that help your body burn more fat. One study found people who drank green tea burned 17 percent more fat during exercise.

Do zero calorie sweeteners break a fast?
No, drinks with zero calorie sweeteners don’t break your fast. Drinks like Coke Zero, Diet Coke, and other zero calorie sodas have no calories and no sugar. Without calories, your body stays in fat burning mode.
Some people worry about insulin spikes from sweeteners. Research shows artificial sweeteners like aspartame and sucralose don’t raise insulin levels in most people. A 2020 study tracked people who drank diet soda during fasting and found no change in their blood sugar or insulin.
That said, some zero calorie drinks can make you feel hungry. The sweet taste might trigger cravings even when there are no real calories. If a diet soda makes you want to eat, stick to water or black coffee instead.
What about drinks with 5 to 10 calories?
Small amounts of calories won’t stop fat burning. Your body can handle 5 to 10 calories and stay in a fasted state. Black coffee with 5 calories or tea with a splash of lemon juice won’t break your fast.
The key number is 50 calories. Most experts say staying under 50 calories keeps you in fat burning mode. Once you go over 50 calories, your body shifts from burning fat to processing food.
Think of it like this. Your body has two settings. One setting burns stored fat for energy. The other setting processes food you just ate. Zero calorie drinks keep you in fat burning mode. High calorie drinks flip the switch to food processing mode.
Can I drink zero calorie sports drinks while fasting?
Yes, zero calorie sports drinks work during fasting. Drinks like Powerade Zero and Gatorade Zero have no calories and no sugar. They also give you electrolytes like sodium and potassium.
Electrolytes matter during longer fasts. When you fast for 16 hours or more, your body loses salt and other minerals through urine. Zero calorie sports drinks replace these minerals without breaking your fast.
Watch out for regular sports drinks. Gatorade and Powerade have 80 to 140 calories per bottle. These calories stop fat burning and break your fast.
Does sparkling water break a fast?
No, sparkling water doesn’t break a fast. Plain sparkling water has zero calories, zero sugar, and zero sweeteners. Your body treats it the same as regular water.
Flavoured sparkling water is fine too, as long as it has no calories. La Croix, Perrier, and San Pellegrino sparkling water all have zero calories. Read the label to make sure. Some flavoured waters sneak in sugar or calories.
What drinks should I avoid during fasting?
Skip any drink with calories. Juice, milk, smoothies, and regular soda all have sugar and calories. These drinks stop your body from burning fat.
Even small amounts add up. A glass of orange juice has 110 calories. A cup of milk has 150 calories. A can of Coke has 140 calories. All of these break your fast.
Alcohol breaks your fast too. Beer, wine, and spirits have calories, and your body processes alcohol before anything else. This stops fat burning completely.
Can zero calorie drinks help me lose weight faster?
Maybe. Zero calorie drinks can help you feel full during fasting. One study found people who drank sparkling water before meals ate 20 percent less food. The bubbles filled up their stomachs.
Coffee and tea can also speed up fat loss. Caffeine raises your metabolism, so you burn more calories throughout the day. Green tea has the same effect. Research shows people who drink green tea burn an extra 100 calories per day.
But drinks alone won’t make you lose weight. You still need a calorie deficit. This means burning more calories than you eat. Zero calorie drinks help by keeping you full and boosting metabolism, but you have to eat less overall.
Do I need to drink zero calorie drinks during fasting?
No, you don’t need anything except water. Water keeps you hydrated and helps your body burn fat. Many people fast with only water and get great results.
Zero calorie drinks just make fasting easier. If plain water gets boring, black coffee or diet soda can help you stick to your fasting window. The best drink is the one that helps you keep going.
