Did you have any problems with your weight or health before going on keto? 

Like many moms, I found myself struggling with post-pregnancy weight. After two children, my weight had climbed to 237 lbs., and my youngest was approaching three years old. I had reached a point where I had completely given up on weight loss. Looking in the mirror filled me with shame, and on October 21, 2016, I decided it was time for a change. I knew something had to give. 

Does exercise play a role in your success on keto? If so, how?

 
Determined to regain control, I committed to working out every single day. My routine consisted of: 

  • 100 minutes on the treadmill 
  • 25 minutes of strength training 

To ensure accountability, I created a rule: any missed workout had to be made up the next day, meaning double the effort. This approach kept me consistent and disciplined. However, despite my hard work, by April 2, 2017, I had only lost 16 lbs., bringing me down to 221 lbs. 

While I was proud of my progress and felt stronger, the weight wasn’t coming off as quickly as I had hoped. I knew I needed something more. 

How does an average day of eating/fasting look for you on keto? 

As long as I avoided alcohol, desserts, and bread products, my weight loss remained consistent. Of course, life isn’t about deprivation—I still enjoy celebratory meals on holidays, vacations, and special occasions. No one wants to eat a salad at a wedding, right? 

To maintain balance, I developed a strategy: If I indulge in a big meal, I compensate by fasting for a full day and then return to my usual eating window. 

I have eliminated pasta, rice, potatoes, and bread for the most part, but I still enjoy fine dining and occasional treats. Every three months, I do a five-day fast to reset my body and promote autophagy, a natural detoxification process. 

How has your health improved since you started keto?   

My husband and I had both been looking for ways to accelerate our weight loss when he discovered intermittent fasting. We decided to try the 20:4 fasting method—20 hours of fasting followed by a 4-hour eating window. The results were astonishing! 

  • In the first week, I lost 6 lbs. 
  • The next week, I saw a similar drop. 
  • By the end of the month, I had lost nearly 20 lbs.! 

Encouraged by this incredible progress, I continued. Over the next two months, I was shedding around 15 lbs. per month. By the fourth month, my weight loss stabilized to an average of 2 lbs. per week. 

 
Today, I am proud to say I weigh 134 lbs.— a total loss of 103 lbs.! My journey has inspired many of my coworkers, who often ask me about my ‘secret.’ I’m passionate about sharing my knowledge, hoping to help others transform their lives as well. 

Any other details you want to share? 

Intermittent fasting, combined with dedication and balance, has completely changed my life. If you’re struggling with weight loss, know that you’re not alone—and that change is possible with the right mindset and strategies.
