What is “Keto”?

If carbohydrates are available, your body will burn that first. If carbs are not available, your body will burn fat & your fat stores! “Keto” (scientifically known as “Nutritional Ketosis” but usually referred to as just “keto” or a “ketogenic diet”) involves restricting your diet to moderate protein, very low carbohydrates and high fat. It’s similar to the the Atkins diet, but with more solid science. When you are consuming enough protein to keep muscles happy, restricting carbohydrates as low as possible and making up the rest of your calories in fat, your body switches into a fat burning mode. Your liver will begin converting fats into energy molecules known technically as “ketone bodies” – which is where the name of the diet comes from. People end up with MORE energy and vitality on a ketogenic diet. Muscle cells are finally gaining energy instead of all the fuel getting stored away in fat cells because of insulin, specifically insulin resistance.

Pretty flask

Make sure you mix your drink in another container if you plan to use the straw cover. I had a terrible mess trying to mix my Keto Chow in the flask.

Great for drinking Keto Chow!

I bought a Vacuum Flask and it's Freaking Awesome! I use it everyday. The vacuum doesn't seem to be working though. I've dragged it along my carpet and it doesn't pick up anything, but for drinking Keto Chow it's Great!


Absolutely needed this for road trips to hold a full serving of KC. Exceptional construction and keeps my KC nice and cold for hours. Thank you!

Great Vacuum Flask

I needed an insulated flask for my water, that would fit in my cup holder of my van as I drive for a living. These are Perfectly Perfect.! They are Pretty and keeps my drinks Cold all day. I can bring my water or my Keto Chow and know it will be the perfect temperature.! And I love that we get 2 different lids with each one to be able to choose which one we need to use.!
