Why We Said Yes to Keto//OS

Perhaps you are wondering  why we said yes to Keto//OS. Well, to be honest we were quite skeptical in the beginning. Could a supplement put someone into therapeutic ketosis in less than hour by using beta-hydroxybutyrate (bhb) salts? So, we decided to put Keto//OS personally to the test.

We had been on a quest to find a tool that could help our community group and those who follow our blog with the low carb keto diet.

We had exhausted all our known resources. We spent countless hours teaching and coaching individuals for free, but we were frustrated with the minimal results we were seeing with the diet alone.

No one is arguing that a low carb ketogenic diet can be done without the help of a supplement like Keto//OS. Sure it's possible, but it's so much harder and we were aiming for people to change their lifestyles not just find a quick fix.

Our heart is to serve our community by sharing what we have learned and what we continue to learn about the benefits of being in ketosis.

As community group pastors we want to see people to whole in spirit, mind and body. We wanted to see lives  transformed, in every sense of the word.

Well, to say we were pleasantly surprised is an understatement. Within minutes of consuming my first serving of Keto//OS I noticed an immediate boost in my ketone levels. I had more energy, greater mental clarity, less fatigue, and my appetite had reduced dramatically. 

Randy noticed that he was able to work-out longer and harder. His post exercise recovering was also remarkably quicker. He too felt the increased energy and appetite suppression. 

Honestly, we were both a bit stunned that we experienced these benefits since we had been doing a low carb ketogenic diet for several years already. We couldn’t believe we could somehow improve what we were already doing by adding  Keto//OS

For the first time we were able to do intermittent fasting easily. Fasting is something that as believers we knew was important part of our Christian walk, but struggled to do so effectively. That's no longer the case for us. 

After testing Keto//OS for a few weeks we realized we had something very special in our hands and that we now had a responsibility to share it.  

Today, we are thrilled that we decided to share this amazing tool. We see how it's helping our family, friends, community group and our blog family too. 

We are always looking for ways to assist people in changing their eating habits, aiming to take all excuses off the table.  We never want to hear that you can't make healthy choices because it's too challenging.

That's what we found with Pruvit's Keto//OS.

It's not that I didn't try doing the low carb diet, I was just never able to stick with the plan until Fittoservegroup introduced me to Keto//OS today I have already lost 30 pounds and I can't be more pleased.-Marilyn Clay

Yvette and Ricky Galllinar's Keto OS Transformation

Our pastors, Ricky and Yvette Gallinar. After having ringside seats to our personal health transformation, they saw the need to open the church, Word of Faith Global to host a Fittoserve Group. Not every ministry would have seen the value of this, but our pastors have a burden for the lost and for the body of Christ to experience optimal health. They had attempted to follow the advice we gave them at Fittoserve Group for over a year, but were finding it very difficult to stay faithful to the lifestyle. It wasn’t until Keto//OS that they were able to do so successfully.
