Does Honey in Tea Break Your Fast? The Truth on Sweeteners and Intermittent Fasting

Intermittent Fasting Overview

Intermittent fasting (IF) describes various eating patterns that cycle between periods of fasting and eating. It has become a popular diet trend based on potential benefits like better weight control, improved metabolic health, and increased longevity.

There are several IF approaches including time-restricted feeding, alternate day fasting, and periodic fasting for 24+ hours 1-2 times per week. The most common involves 16:8 fasting, with 16 hours of fasting and an 8 hour eating window daily.

Metabolic Changes During Fasting

Fasting triggers several metabolic adaptations and changes:

• Lower insulin levels which enhances fat burning.
• Increased levels of human growth hormone.
• Reduced oxidative stress and inflammation.
• Increased lipolysis to break down fat.
• Ketosis - using fat for energy instead of carbs.

Adhering to the fasting period is important to generate these benefits. Even small amounts of calories can inhibit them.

Does Honey Break a Fast?

Yes, consuming honey will technically break a fast during intermittent fasting. Honey contains calories and raises insulin levels, so it does not meet the criteria for remaining in a fasted state.

Insulin and Calorie Response

While honey has a lower glycemic index than sugar, it still elicits an insulin response like other sugars and carbs. Just 10 grams of honey (around 2 teaspoons) contains 35 calories.

This insulin spike inhibits lipolysis, ketosis, autophagy, and other fasting responses. So honey is not considered a "fasting-friendly" sweetener.

Potential Impact on Fasting Benefits

Drinking tea or coffee with honey during the fasting window could potentially diminish some of the beneficial effects of intermittent fasting including:

• Lower fat burning and reduced weight/fat loss.
• Inability to enter into or maintain ketosis.
• Blunted impact on cellular repair processes like autophagy.
• Smaller improvements in insulin sensitivity.

Best Sweeteners for Fasting

To sweeten tea or coffee during a fast, there are several better options than honey that won't disrupt your fasted state:

Stevia

Stevia leaf extract has zero calories and carbs. It does not raise insulin or blood sugar at all, making it ideal for use when fasting.

Monk Fruit

Monk fruit or luo han guo is another plant-derived sweetener with zero calories, allowing it to be used during fasting windows.

Erythritol

Erythritol is a sugar alcohol that contains almost no calories and has negligible effects on insulin and blood sugar.

Sucralose

Splenda and other sucralose-based sweeteners provide sweetness without calories or insulin-spiking effects.

Aspartame

Aspartame, also known as Equal or Nutrasweet, is another very low calorie artificial sweetener that won't impact your fasted state.

Can You Have Cream or Milk in Fasting Tea/Coffee?

Adding a splash of milk, cream, or dairy-based creamers to tea or coffee will also technically break your fast. These contain calories that elicit an insulin response and take your body out of a fasted state. To keep your fast, drink tea and coffee black or use non-dairy milk like almond or coconut milk.

Effects on Autophagy

Research indicates that consuming even very small amounts of calories suppresses autophagy, a repair process where cells recycle waste and damaged components. This indicates cream or milk should be avoided to fully benefit.

Fat Burning

Consuming cream or milk causes a rise in insulin, which inhibits lipolysis and ketosis. This reduces the ability to burn fat for fuel during the fasted state.

Will Honey Stop Autophagy?

Yes, consuming honey during your fasting period will disrupt the process of autophagy. Autophagy peaks within the first few hours of fasting and is inhibited by insulin, amino acids, glucose, and other stimuli.

Research in mice found that adding a small amount of honey to water inhibited autophagy nearly completely in various tissues. So even small amounts of honey can shut down this fasting-induced cellular recycling process.

Importance of Autophagy

Autophagy provides many beneficial effects including:

• Removes damaged cell components that can cause disease.
• Protects against neurodegenerative diseases like Alzheimer's.
• Prevents metabolic abnormalities.
• Extends lifespan and healthspan.

Maximizing autophagy is one of the key mechanisms by which fasting promotes health.

Does Honey End Ketosis?

Yes, consuming honey during your fast will kick you out of ketosis. The carbohydrates and sweeteners in honey are quickly absorbed and raise blood sugar and insulin, which inhibits ketone production.

Impact on Ketone Levels

Studies show even small doses of carbohydrates significantly reduce blood ketone levels. One study found taking in just 8 grams of carbs decreased blood ketones by 50% within an hour.

Downsides of Exiting Ketosis

Losing the metabolic benefits of ketosis can minimize the advantages of fasting including:

• Reduced capacity to burn fat for fuel.
• Blunted inhibition of appetite and cravings.
• Impaired cognitive and physical performance.
• Reduced antioxidant and anti-inflammatory effects.

Tips for Drinking Tea/Coffee During a Fast

Here are some tips for enjoying your morning tea or coffee without disrupting your intermittent fast:

• Drink plain with no creamers, milk, or sweeteners.
• Flavor with cinnamon instead of sugar or honey.
• Use stevia or other zero-calorie sweeteners if you need sweetness.
• Opt for green, black, or herbal teas which have health benefits.
• Limit yourself to 2-3 cups spread throughout the fasting period.

The Bottom Line

Does honey in tea break your fast during intermittent fasting? Unfortunately, yes - even small amounts of honey can inhibit fat burning, ketosis, and autophagy from your fast. Stick to calorie-free sweeteners like stevia or monk fruit instead to maintain a fasted state and reap the full rewards.
