"I tried Dr. Joy’s Fast to Fit program as my first introduction into fasting and have loved it and shared my journey with many friends! I had no idea about all of the positive effects both short-term and long-term that fasting has. Joy provides so much insight and has always been able to thoroughly answer any questions I have. She shares so much data and research that has been done on fasting. I have been enjoying having several hours between my last meal of the day and going to bed and feeling more energy and less brain fog in the morning due to it. It’s not nearly as difficult as I expected it to be and it feels good knowing that I have a regimen to keep me from late night snacking (usually not healthy snacking!) I would recommend this program to anyone who is interested in learning about different ways to approve upon your overall health both physically and mentally!!

"I joined the Fast to fit to have a jump start on my journey. Though fasting is proven to work, I’ve never done it the way the fast to fit program educated me. It was always so restrictive and too many other information that was lacking, in this program I learn that mimicking fasting can carry you over, boost your energy and in-fact make the journey enjoyable. I lost some inches off my waist! Though I have a ways to go to meet my goals, I’ve learned that the process is to be enjoyed and not restricted. I always reminded myself, “DELAY NOT DENY”. Though it’s a simple phrase, it’s such a powerful one. Helps you carry it over to make it to the next meal or look forward to start the day right. I want to continue to implement this lifestyle and slowly meet my goal. 1% better everyday."

No, this program focuses on when to eat rather than what to eat. You can choose your preferred eating style within the fasting framework.
Fasting is generally safe for most healthy adults. However, it’s essential to consult with your doctor if you have specific conditions like diabetes, are pregnant, breastfeeding, under 18, or taking medications. The program also highlights precautions to ensure safe fasting practices.
Some hunger is normal initially, but your body adjusts as it becomes metabolically flexible. We’ll provide tips to manage hunger and boost energy, such as staying hydrated, using mindfulness techniques, or consuming healthy fats like MCT oil.
You are never too behind. You can catch up at your convenience. And you can join group discussions any time.
