Can You Drink Tea and Coffee on Fast 800?

4 min read

According to official Fast 800 guidelines, followers do not have to give up tea and coffee. While plain, black versions are encouraged during fasting periods, the addition of milk or sugar requires careful consideration to avoid exceeding the daily 800-calorie limit.

Quick Summary

Yes, you can drink tea and coffee on the Fast 800 diet, but strict adherence to calorie rules is essential. Plain black versions are best during fasting windows, while any additions like milk or sugar must be factored into your daily calorie count to maintain effectiveness.

Key Points

  • Black is Best: Unsweetened black tea and black coffee are permitted and calorie-free, making them suitable even during fasting periods.

  • Count Calories for Additives: Adding milk, sugar, or creamers to your drinks adds calories and should be accounted for within your 800-calorie limit, particularly on intensive days.

  • Herbal Tea is Safe: Calorie-free herbal teas are an excellent way to stay hydrated and enjoy flavour without disrupting your fast.

  • Moderation with Caffeine: The Fast 800 recommends limiting caffeinated coffee to one to two cups per day to avoid potential side effects like jitters or disrupted sleep.

  • Listen to Your Body: Pay attention to how your body responds to caffeine on an empty stomach and adjust your intake or timing accordingly.

  • Prioritise Hydration: Remember to drink plenty of water alongside your tea and coffee to maintain proper hydration levels.

Navigating Beverages on the Fast 800

The Fast 800 diet, created by Dr. Michael Mosley, is an innovative approach to weight loss and metabolic health, combining intermittent fasting with a Mediterranean-style diet. During the intensive phases, followers restrict their daily calorie intake to 800 calories. This often raises questions about everyday beverages, particularly popular caffeinated drinks like tea and coffee. The good news for many is that these beverages are not strictly off-limits, but there are important rules to follow, especially when it comes to time-restricted eating (TRE).

The Golden Rule: Plain and Black is Best

The most straightforward answer is that plain, black tea and black coffee are perfectly acceptable on the Fast 800 diet, even during fasting windows. This is because they contain virtually no calories and do not cause the insulin spikes that would disrupt the fasting state. For those following a TRE schedule, such as the 16:8 method, these calorie-free options are excellent for staying hydrated and managing hunger pangs during the fasting period. A small amount of caffeine can also provide a temporary energy boost, which some people find helpful.

What About Additions Like Milk and Sugar?

Things get more complicated when you introduce additives. The moment you add milk, sugar, syrups, or creamers to your tea or coffee, you are adding calories, and this is where you can compromise your progress on the Fast 800. For strict fasting periods within a TRE schedule, any calorific addition will technically break the fast by triggering a metabolic response.

During your eating window, you can certainly enjoy tea or coffee with milk, but it is crucial to count the calories. The official Fast 800 guidance suggests that a small dash of full-fat milk is acceptable, though it will break a strict fast. A cup of coffee that becomes more like a latte, however, with a significant amount of milk, will consume a notable portion of your daily 800-calorie budget. For those aiming for long-term health and weight maintenance after the intensive phase, incorporating milky coffees becomes part of the balanced 'Way of Life' approach.

Herbal Tea: A Hydration Hero

Herbal teas are another fantastic option for Fast 800 followers, offering flavour and variety without the calories, provided they are unsweetened. Many herbal teas, such as peppermint, chamomile, or ginger, contain powerful antioxidants and can provide a calming or soothing effect, which can be beneficial during a period of calorie restriction. Like black tea and coffee, herbal teas are suitable for both fasting windows and eating periods, and they count toward your daily fluid intake.

Comparison Table: Fast 800 Drink Choices

Beverage Type Fasting Window (TRE) Eating Window (800-Calorie Day) Caloric Impact Potential Benefits
Black Coffee Yes Yes Minimal (approx. 3 kcal per cup) Energy boost, appetite suppression, antioxidants
Black Tea Yes Yes Minimal (approx. 2-3 kcal per cup) Antioxidants, hydration
Herbal Tea Yes Yes Minimal (negligible) Hydration, soothing properties, variety
Coffee with Milk Breaks Fast (avoid) Yes (count calories) Low to High Taste enjoyment, protein intake (with full-fat milk)
Tea with Milk Breaks Fast (avoid) Yes (count calories) Low to Moderate Taste enjoyment
Sugary/Syrup Drinks Breaks Fast (avoid) Avoid (use calorie budget wisely) Very High Avoids fast; uses up calories inefficiently
Bulletproof Coffee Breaks Fast (avoid) Yes (consider high calories) Very High Keto-friendly, but high in calories; not suitable for 800-cal days

Practical Tips for Integrating Tea and Coffee

  • Prioritise Hydration: Always start your day with a large glass of water before your first coffee or tea to rehydrate your body after sleep.
  • Moderation is Key: While black tea and coffee are permitted, excessive caffeine intake can lead to jitters, sleep disruption, or stomach upset, especially on an empty stomach. The Fast 800 team suggests limiting caffeinated cups to one or two per day.
  • Listen to Your Body: If drinking black coffee or tea causes stomach discomfort during your fasting window, try switching to a lower-acidity blend or delaying your first cup until after your eating window begins.
  • Get Creative with Calorie-Free Flavour: Instead of sugar, try adding a sprinkle of cinnamon, nutmeg, or a squeeze of lemon to your black tea or coffee for extra flavour without the calories.
  • Consider Substitutes: If you find black coffee too harsh or need to curb your caffeine, consider The Fast 800's specific coffee shake or opting for decaf versions.

The Final Sip

In conclusion, the answer to the question "Can you drink tea and coffee on Fast 800?" is a definitive yes, with some important caveats. By sticking to plain, black, and unsweetened versions during fasting windows, and carefully factoring any additions into your daily calorie allowance on eating days, you can continue to enjoy these popular beverages without derailing your weight loss goals. Hydration is paramount, and listening to your body's individual response to caffeine and additives is crucial for a successful and sustainable Fast 800 journey.

Conclusion: Making Smart Beverage Choices on Fast 800

The Fast 800 allows for the enjoyment of tea and coffee, provided smart choices are made. For maximum fasting benefits, plain and unsweetened versions are the best options. Any calorific additions, whether a splash of milk or a keto-friendly fat, should be consumed only during your eating window and counted towards your daily calorie total. By understanding these simple rules, you can stay hydrated, satisfied, and on track with your Fast 800 diet.

Frequently Asked Questions

Technically, yes, a dash of milk will break a strict fast because it contains calories. However, according to Dr. Mosley, if a small amount of milk (e.g., a dash of full-fat milk under 30ml) helps you stick to the diet, it is acceptable, though it should be counted in your calorie total on 800-calorie days.

Yes, absolutely. Unsweetened herbal teas, such as mint, chamomile, or rooibos, are calorie-free and do not break a fast, making them a great option for staying hydrated.

While zero-calorie sweeteners do not add calories, some practitioners prefer to avoid them during fasting periods as the sweet taste can potentially trigger a hunger response in some individuals. For most, a small amount is unlikely to be an issue, but it's safest to stick to plain black beverages during a fast.

The Fast 800 recommends moderation with caffeine, suggesting followers stick to one or two cups of caffeinated coffee per day to avoid potential side effects like anxiety or sleep disruption.

No, Bulletproof coffee, which contains butter or MCT oil, provides a significant number of calories and fat. It will break a fast and use up a large portion of your 800-calorie allowance, so it is not recommended for this diet.

For those adding milk during their eating window, official guidance suggests using full-fat milk. A small dash is preferable to avoid exceeding your calorie limit, especially compared to higher-calorie options like lattes.

Some individuals may experience stomach upset, heartburn, or jitters from drinking coffee on an empty stomach. If this occurs, try a lower-acidity coffee, reduce your intake, or delay your first cup until after your eating window opens.
