What Breaks a Fast? | The Epoch Times

Have you ever wondered if taking your morning multivitamin breaks your fast? Or if having coffee or lemon water affects your fasting efforts?

When it comes to fasting, any intake of calories, no matter how small, can end the fast. However, the impact of certain foods and drinks on fasting is not always clear-cut.

“We have theory, and we have practice. Many of these things haven’t been extensively researched in the academic world yet,” explained nutrition scientist Samefko Ludidi.

“The mechanisms of intermittent fasting come into play when there is no food intake for at least 14 hours. This leads to benefits such as decreased blood glucose metabolism and increased fat-burning capacity,” Ludidi stated.

Autophagy

Autophagy, the process of breaking down damaged cell structures, occurs during longer periods of fasting (around 20-24 hours), with further enhancement after fasting for up to 48 hours. However, fasting for more than 48 hours may not provide significant additional benefits.

Exploring Gray Areas

Considering that the definition of breaking a fast varies based on your goals, it’s essential to be aware of common foods and drinks that fall into a gray area.

Coffee and Tea

Black coffee and unsweetened teas are generally safe during fasting, as they do not contain calories or sugar. However, black coffee may trigger cortisol and a stress response in some individuals, potentially affecting blood sugar levels.

Adding Cream or Sugar

Adding fats to coffee breaks the fast in terms of calorie restriction, but can still keep you in ketosis if that is your goal. It’s important to differentiate between fasting and staying in a ketogenic state when adding fats to beverages.

“If you need energy from nutrients while fasting, adding fats can help you stay in a fat-burning mode and avoid sugar burning, aiding in weight loss,” Ludidi explained.

Vitamins and Lemon Juice

Vitamins with minimal carbohydrates, such as fish oil supplements or those with fillers like rice bran or gelatin, are a gray area. The small amounts of sugars and fats in these supplements are unlikely to immediately disrupt ketosis, especially when consumed in moderation.

“Having a small amount of carbohydrates, such as in a squeeze of lemon juice, is unlikely to impact your metabolism significantly,” Ludidi said.

Overall, the discussion around consuming carbs during fasting revolves mainly around maintaining ketosis. It’s important to consider your individual goals and make choices that align with them.

The quantities of lemon juice or vitamin pills discussed are significantly lower than the 10, 15, or 20 grams of carbohydrates,” he explained.

Electrolytes, which are calorie-free salts, are safe to consume during fasting according to Ludidi. They can aid in hydration and help control hunger during prolonged fasts.

Ludidi emphasized the benefits of electrolytes during fasts lasting longer than 16 or 18 hours. He pointed out that electrolytes do not provide energy or calories, allowing the body to remain in a fasted state. Additionally, they can help manage intense food cravings during extended fasts.

When it comes to artificial sweeteners and sugar alcohols, Ludidi advised against their consumption during fasting. These substances may trigger an insulin response and interfere with fat and sugar metabolism, potentially breaking the fast.

Ludidi also cautioned against using protein powder and collagen supplements while fasting, as they can disrupt the fasting state by providing amino acids that can be converted into energy. He recommended consuming these supplements shortly before breaking the fast to still benefit from rapid gastric emptying.

Chewing gum during fasting is a personal choice, according to Ludidi. The minimal amounts of artificial sweeteners or carbs released while chewing are unlikely to affect fasting. If it provides a sense of freshness and security, chewing gum is deemed acceptable.

Regarding bone broth fasts, Ludidi stated that sipping on bone broth during longer fasts may not significantly interfere with fasting. The trace amounts of amino acids in bone broth are unlikely to disrupt the fasting state.

In terms of fasting best practices, Ludidi advised gradually increasing fasting hours rather than jumping into long fasts immediately. He recommended starting with 14 hours and gradually working up to longer fasting periods to listen to the body’s signals and avoid overexertion.

When breaking a fast, Ludidi suggested starting with fats or proteins before introducing carbohydrates to avoid digestive discomfort. He emphasized the importance of reintroducing foods in a specific order to aid in digestion and prevent bloating.

Overall, Ludidi stressed the importance of self-care in fasting practices and advised against pushing the body too hard. Listening to the body’s signals and gradually increasing fasting periods can lead to more sustainable and beneficial fasting outcomes. “It would be intriguing from a practical perspective as people often have these inquiries. However, we cannot definitively state whether vitamin pills or lemon juice with a small amount of sugar, perhaps half a gram, can kick you out of ketosis or disrupt your fasting regimen,” he explained.

When determining what breaks your fast, it is essential to consider the ingredients in the food and beverages and align them with your objectives. Look for carbohydrates, any type of sugar, protein, fat, and the overall calorie content. Then, assess whether it will impact your fasting.”
