Add 14oz warm water (or up to the 20 oz line)… and shake!


Or refrigerate for 30 mins or even overnight to bring out more flavor

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.

Vacuum flask so awesome

On keto I drink a lot of water. I also have to fill my normal water bottle often. I put ice in this flask, fill it several times all day,, and there's still ice left in the morning! Love this flask. I totally recommend it to everyone. Bonus is that it's such a beautiful color.

Great purchase!

Absolutely fantastic! I purchased the ocean quartz and the colors are so pretty. I am a school bus driver and the easy open/drink straw is a lifesaver so I don't have to take my eyes off of the road. It also has been keeping my drinks cold ALL day! From 5 am until 430 pm and I still have ice in it. I Absolutely love this flask! Thank you Keto Chow for making a bottle I can easily use on my bus and I don't have to worry about it spilling!!
