This is also available in a larger 32oz size.
If you've been reading the blog very long, you'll probably know that we've been advocating vacuum insulated flasks for years and now they're available with a super cool Keto Chow logo laser etched on one side. Perfect for when you're:
- Staying Keto at a conference.
- Running around a weird city (sorry San Francisco, you know it's true =).
- Stuck in a class all day and you know the lunch options are going to completely suck.
- Driving around.
- Hiking
- Running around Disneyland (though those smoked turkey legs are pretty awesome).
You need to either pre-refrigerate your Keto Chow for several hours or add in some ice cubes - in our experience, the insulated flasks will keep Keto Chow cold for at least 18 hours but the liquid needs to already be cold! The double-wall vacuum insulation keeps hot drinks hot up to 12 hours and iced drinks cold up to 24 hours. The stainless steel won't transfer flavors or odors to your next drink. This means your favorite beverage is always pure and refreshing.
The flip-top lid should keep your gear nice and clean but please do make sure that you close the lid before you put it in your backpack.
Made from stainless steel with double-walled and vacuum-sealed insulation, this durable wide-mouth bottle keeps your drink at its optimum temperature for hours. And, its exterior never sweats. So say goodbye to coasters and slippery bottles!
Plus, it's got a variety of lids to choose from! Each Keto Chow Stainless Steel Vacuum Insulated Flask comes with a BPA-free plastic Flip Lid with a handle (ideal for hot liquids) and a stainless steel twist-on lid.
The 22oz is 2.9 inches wide at the base; 9.4 inches tall; weighs 11oz; keeps drinks cold for 24 hours and hot for 12 hours; and fits most cupholders.
The Keto Chow Stainless Steel Vacuum Insulated Flask is hand wash only. Manufactured by Simple Modern.
Information on the above warning: Keto Chow and Heavy Metal Exposure (Proposition 65 warning).
The short version: The Keto Chow shakes have an almost immeasurable amount of lead (if a product has plants in it - like spices for flavor - the plants pick up traces of lead) - but that level is over the line that California has decided could potentially cause birth defects... if you consume 1000x the amount that requires a warning. So a warning to California residents is required by law (as you see above).Longer version: For any unaware, California has a fun citizen's initiative commonly referred to as "Proposition 65" or "Prop 65" - it's the reason many consumer products have a warning that "this product contains chemical known to cause cancer in California" (or similar) which is generally followed by everyone thinking "good thing I'm not in California!" I'll not get into the validity of the "No Significant Risk Levels" and "Maximum Allowable Dose Levels" established as part of Prop 65, they are what they are, and if a company sells something to a resident of California, a California resident (usually a lawyer) has the ability to sue if there is not a warning and the product contains levels of heavy metals or other contaminants higher than the levels established. I can say that the heavy metal levels in Proposition 65 are low enough that coffee shops have had to post warnings and Disneyland has warnings in their picnic area. Keto Chow was served a notice that "Safe Products for Californians" intends to sue Keto Chow for not having warnings that Keto Chow contains heavy metals, specifically lead. The tactic being that many of the levels defined by Proposition 65 are so absurdly low that quite literally EVERYTHING has enough lead to qualify for needing a warning. Also, since Keto Chow contains protein, and the 'cool' thing to do these days is use plant protein which tends to be from China and contains a lot of heavy metals, logically Keto Chow will contain heavy metals (like Soylent™ does). The thing is: we don't use plant protein, instead we only use protein created by sustainable mobile bioreactors (ruminants); in fact, very few of the ingredients come from plants and the animals don't absorb heavy metals. Due to the lawsuit, we paid for an independent lab to test for heavy metals in Keto Chow, the complaint was only for "Lead and Lead Compounds" but we went ahead and had Arsenic, Cadmium, Lead, and Mercury tested. The test has a minimum measurable level of 0.01 mg/kg of material, and each meal of Keto Chow is around 44-50g of powder. Here are the measured levels of heavy metals in Keto Chow, the serving size, and what your exposure is compared to the allowed levels with one caveat: the cadmium level is only established for inhalation, if you ingest it orally there is not established level. Lead is interesting, Proposition 65 establishes a "No Significant Risk Levels" for causing cancer set at 0.015 mg or 15 micrograms per day. Lead also has a "Maximum Allowable Dose Levels" (MADL) for causing reproductive harm of 0.0005 mg or 0.5 micrograms per day. The MADL is set by looking at the level that no observable effect occurs and dividing that by 1000. In other words, if a toxin causes an effect at 10 units, the MADL would be defined at 0.01 units; meaning that the dose where lead will cause reproductive harm is 0.5 mg or 500 micrograms per day. I guess it's surprising that many of the flavors of Keto Chow do NOT contain enough lead to require a warning label. Notably, the ones with the highest levels are those that contain spices or other plant-derived flavorings.

Chocolate and Mocha both contain cocoa powder, a plant product, and both have the highest levels of heavy metals on the list; though the levels are still far below the very low bar set by Proposition 65 to necessitate a warning for cancer. The threshold for needing a "reproductive harm" warning is 0.00050 mg - as a precaution against future litigation we just went ahead and put the warning up for everything.
