Actually there is science behind it. Its using Beta Hydroxybutrate Salts
Check out EvoMuse KetoInduce.... It uses them as well to induce Ketosis.

Betahydroxybutyrate (BHB salts)
First off, we will take a quick look at Beta-Hydroxybutyrate salts (abbreviated as BHB, you will also often see it abbreviated as BOHB).
Up until recently, the technology to take oral BHB did not exist. Oral ketone esters existed, which convert to ketones in the body, but they were completely cost prohibitive for general public consumption, apparently tasted god-awful, and unlikely to be able to be legally sold as a supplement anyway. But luckily our favorite Mad Scientist, Patrick Arnold, was able to develop a viable alternative. After a year of work, and even having to develop new advanced analytical testing methods, he created a ketone product that is stable, won’t make you gag, and is pretty cost effective.
Acectoacetate, the other primary ketone body, was not an option orally, due to it’s instability and potential to rapidly break down into acetone. So in the form of BHB salts, we now have the ability to literally drink ketones, and experience many of the benefits of being in a fully adapted state of NK.
For BHB to be a viable option, it has to be ingested with a large amount of sodium and potassium (calcium BHB is also available now), so you’ll notice a significant amount of these electrolytes in the KI formula. This is actually quite beneficial however, as being in a state of ketosis (even temporarily) causes the kidneys to upregulate water and sodium excretion, and potassium tends to drop when sodium does so that your body can maintain a proper balance. So you need to replenish this sodium dump, which makes the 842mg per serving pretty handy. Initially, the first few days of using KI, you may want to cut back on sodium in your diet slightly by reducing sodium at dinner, as this will be in close proximity to your night time dose of KI.
When ingesting BHB salts, you will typically see a peak in blood levels between 30-60 minutes, with a return to baseline at about the 3-4 hour mark. However, this doesn’t mean you’re going to be back out of ketosis halfway through the night. Because, you are in a fasted state, and due to the other ingredients in KI, you have basically kick-started your body’s own production of ketones through fatty acid conversion in the liver and acetoacetate production from the amino acids included in KI. This has been confirmed through user data with KI beta testers showing ketones well above the NK threshold in the morning.
