Understanding ProLon: Can I drink La Croix on ProLon?

4 min read

According to the ProLon guidelines, plain sparkling water is generally permitted during the 5-day Fasting Mimicking Diet. However, many wonder if flavored versions of sparkling water, such as La Croix, are also compliant. The key question is: Can I drink La Croix on ProLon?

Quick Summary

Yes, unsweetened La Croix is generally acceptable on the ProLon diet, as it contains only natural essence and zero calories, which keeps the body in a fasting state. However, it is essential to review ingredients carefully, as strict fasting protocols and individual tolerance levels can vary.

Key Points

  • La Croix Compliance: Unsweetened La Croix is generally permitted on ProLon due to its natural, calorie-free flavorings.

  • Natural Flavors Only: ProLon's guidelines allow sparkling water with natural flavors, provided there are no sweeteners of any kind.

  • Zero Calorie, Zero Sweetener: La Croix contains zero calories, zero sweeteners, and zero sodium, which is compliant with the fasting protocol.

  • Potential for Mild Response: While compliant for most, the natural essence might trigger a mild cephalic-phase insulin response in highly sensitive individuals, though it typically does not break the fast.

  • Plain Water is Safest: If you are concerned about any potential flavor-related effects, plain water remains the safest, most recommended beverage during the fast.

  • Avoid Artificial Sweeteners: The ProLon protocol and stricter fasting guidelines typically prohibit all artificial sweeteners, even in diet sodas.

  • Check All Flavored Waters: Always check the ingredients of any flavored sparkling water, as not all brands are created equal and some may contain non-compliant additives.

The ProLon Protocol: Fasting with Food

The ProLon Fasting Mimicking Diet (FMD) is a five-day program designed to provide the benefits of a prolonged fast while still consuming a limited number of calories from specific, pre-packaged foods. The diet is carefully formulated to keep the body's nutrient-sensing pathways—such as protein kinase A (PKA), mTOR, and IGF-1—down-regulated, which allows the body to enter a fasting state and initiate cellular renewal processes like autophagy.

To achieve this, the diet strictly controls the intake of carbohydrates, proteins, and sugars. Because the program's effectiveness relies on precise nutrient ratios, it is crucial to stick to the contents of the ProLon kit. Straying from the plan, especially by consuming calories, sugars, or artificial sweeteners, can break the fast and diminish the program's intended benefits.

What Drinks are Allowed on ProLon?

Hydration is vital during any fast, and ProLon provides specific guidance on what can be consumed in addition to the items in the kit. The approved beverage list is limited to liquids that will not activate the body's metabolic processes or stimulate an insulin response.

Approved Liquids:

  • Water: Plain, still, or sparkling water is the most recommended beverage and should be consumed generously. Drinking plenty of water is essential for staying hydrated and can help manage hunger.
  • Herbal Tea: Unsweetened, caffeine-free herbal teas are permitted. ProLon kits include specific teas like spearmint, lemon, and hibiscus.
  • Coffee: You can have up to one cup of plain black coffee per day (limit 140mg caffeine), but it must not contain any sugar, milk, or other additives.
  • L-Drink: The glycerol-based L-Drink is a flavored water solution included in the kit and should be consumed as instructed on days two through five.

Liquids to Avoid:

  • Sugary drinks like juice or soda
  • Drinks with artificial sweeteners
  • Milk or other dairy products
  • Alcohol
  • Bone broth
  • Anything with significant calories, carbs, or protein

The La Croix Question: Ingredients and Compliance

So, where does La Croix fit into these rules? The answer lies in its simple, calorie-free ingredient list. La Croix sparkling water is made with only two components: carbonated water and natural fruit essence.

La Croix's compliance with the ProLon diet is supported by a specific clarification in ProLon's official FAQs, which states that "sparkling water with natural flavors only and without sweeteners of any kind" is an acceptable addition. Since La Croix uses natural essence oils for flavor and contains zero calories, zero sweeteners, and zero sodium, it meets these criteria.

The Nuance of Natural Flavors

While La Croix's ingredients are compliant, some individuals on stricter fasting protocols may prefer to stick to plain water. This is because the flavor, even from natural essences, can potentially trigger a cephalic-phase insulin response in some people, where the body begins to prepare for food upon tasting a flavor. However, for most, and according to the specific ProLon guidelines, the minimal impact of the natural essence in La Croix is considered acceptable and will not break the fast. It can be a helpful tool for those who crave a flavored beverage to help them stick to the program.

Conclusion: Mindful Choices for Your Fast

In summary, for those adhering to the ProLon FMD, you can drink La Croix on ProLon. The brand's commitment to using only natural essences and having zero calories or sweeteners aligns with the program's specific rules for flavored sparkling water. It can serve as a refreshing, hydrating option to provide variety and help curb cravings without compromising the fasting state. However, as with any dietary modification, listening to your body is paramount. If you feel that any flavor, however natural, is triggering undesirable responses, it's best to stick to plain water.
