You're doing great, and you should be proud of how far you've come. Around Day 2, your body typically shifts into ketosis, switching from glucose to its own fat stores for fuel.

Many users report more energy and better focus and clarity once the fast is complete. Some people notice brain fog, headaches, fatigue, body aches or nausea early in the fast. If your body is used to its daily dose of caffeine, you may feel the effects of caffeine withdrawal at this point. Gastrointestinal discomfort, especially constipation, can also occur because of the program's fiber content. Take heart: these are common early in the fast, as your body adjusts.

You can expect your day 2 calorie intake to be lower than Day 1, and it will remain at this level for the rest of your fast. Today also marks the introduction of our L-Drink, a glycerol-based beverage designed to support hydration and help protect lean muscle. Be sure to follow the label instructions, and adjust your intake based on your body weight. For added flavor, consider mixing in some of your hibiscus tea to sip on throughout the day!

Tips for a Successful Day 2:

  • Start Prep For Post-Fast: Now would be a good time to get a headstart on ensuring you have any post-fast longevity products, or ingredients, for Day 6 and 7 meals close at hand. When the time comes to start eating regularly again, we recommend our L-Protein, for example, as an easy post-fast option, and a convenient way to get the plant-based protein you need.
  • Managing Symptoms: If you're still feeling fatigued or achey, consider taking a nap, drinking more water, or indulging in an Epsom salt bath to relax. In the rare case of severe symptoms (intense dizziness or fainting, vomiting, confusion, severe headaches, or trouble breathing), break your fast by consuming something sugary, and consult your primary care physician if necessary. In case of emergencies, call 911.
  • Prep for Post-Fast: Stock up on Fasting Bars, Fasting Shake, and everyday longevity products to help transition out of your fast.
  • Keep Up The Good Work: Keep going: you’re on the right track.
