I bought a big bottle of MCT oil a month ago when at the apex of my “buy the solution” phase. Not super impressed. It’s tasteless, clear and will work in mayo or any sort of cooking, [Correction, from @Stabla, thank you - it has a low smoke point and should not be used for any sort of high heat cooking] but it seems totally fake to me. I have doubts about the way it was processed and wondering what possessed me to buy this when I’m normally pretty gung ho about natural eating. Currently I use it more often on the dry skin on my legs than in my frying pan.
Also in the grip of stupidity I bought a very expensive jar of exogenous ketones - Perfect Keto Vanilla. Too sweet / bitter, and totally useless for actually getting my body in ketosis, I was simply peeing out the ketones I just ingested. Complete waste of money.
Let’s see.
I bought a scale that would measure fat percentage. it’s so ridiculously inaccurate about body fat that I just laugh when I get on. It wasn’t expensive and more accurate than my old scale, so not quite a waste of money, but if my old scale worked it would have been more stupid spending.
I bought some ketostix. They were fun but I learned quickly that they’re simply a yes or no answer, and if I’m eating my 20 grams of carb or less, I know I’m in ketosis because otherwise i’d be dead.
I did buy a cheap breathalyzer. That’s also more or less a yes or no tool but it actually measures acetone byproduct rather than spilled ketones, and it does react to carbs in my diet. Not necessary but a fun tool for $7.
I use a tape measure and if you don’t have one of those I’d recommend it.
Maybe this should be a separate thread entirely, but that’s the extent of my purchasing mistakes.
