There are things you can do to get into ketosis faster. We explain how to get into ketosis and ways to make transitioning into ketosis easier. But first, we go over some facts about ketosis you need to understand before you start your keto journey. We will also explain the science behind ketosis, including how long it realistically takes for your body to make the switch.

Oral beta-hydroxybutyrate supplementation in two patients with hyperinsulinemic hypoglycemia: monitoring of beta-hydroxybutyrate levels in blood and cerebrospinal fluid, and in the brain by in vivo magnetic resonance spectroscopy.

Exogenously delivered ketone supplements significantly altered rat weight gain for the duration of the study (Fig. 6). However, rats did not lose weight and maintained a healthy range for their age. Rats have been shown to effectively balance their caloric intake to prevent weight loss/gain [97–99]. Due to the caloric density of the exogenous ketone supplements (Table 1) it is possible for the rats to eat less of the standard rodent chow and therefore less carbohydrates while maintaining their caloric intake. Food intake was not measured for this study. However, if there was a significant carbohydrate restriction there would be a signifcant change in basal blood ketone and blood glucose levels. As the hallmark to the KD, carbohydrate restriction increases blood ketone levels and reduces blood glucose levels. Neither an increase in basal blood ketone levels nor a decrease in basal blood glucose levels was observed in this study (Fig. 7). Additionally, if there were an overall blood glucose decrease due to a change in food intake, this would not explain the rapid reduction (within 30 min) in blood glucose correlated with an elevation of blood ketone levels after an intragastric bolus of ketone supplement (Figs. 2, ​,33 and ​and44).

Plus, take a look at this promotional video from Prüvit. It claims that “ketones make the fat melt off your body”, which is simply not true (I’ll get back to this later). It also claims that if you wanted to reach ketosis naturally, you would either need to work out 10x harder and longer or be like one of the “extreme people” who “biohack their bodies” to get into ketosis, which “can take weeks or months”. For me, this is irresponsible. A keto diet can be simple and enjoyable, but this video makes switching to a healthy, real food, keto diet sound extreme and difficult while promoting an easy way out in the form of a drink. And that’s just bad advice.

Baseline measurements showed no significant changes in triglycerides or the lipoproteins (data not shown). Data represent triglyceride and lipoprotein concentrations measured after 4 weeks of daily exogenous ketone supplementation. No significant change in total cholesterol was observed at 4 weeks for any of the ketone treatment groups compared to control. (Fig. 1a). No significant difference was detected in triglycerides for any ketone supplement compared to control (Fig. 1b). MCT supplemented animals had a significant reduction in HDL blood levels compared to control (p < 0.001) (Fig. 1c). LDL levels in ketone-supplemented animals did not significantly differ from controls (Fig. 1d).

Intermittent fasting will significantly help the body transition into ketosis as limiting your consumption of food for that many hours will help deplete the system of any excess glucose. It’s a shock to the system and research has shown that daily fasting can have other profound effects aside from weight control such as autophagy, lowering risks of heart disease and diabetes, as well as an improvement in cognitive function. So if you’re still wondering how to get into ketosis in 24 hours, then fasting will surely kick things into gear!
Electrolyte Imbalance – The physiological reasoning behind electrolytes becoming depleted during a state of ketosis is due to lack of water retention and frequent urination. When supplementing with exogenous ketones, the acute state of ketosis will likely increase the frequency of urination, but it won’t deplete glycogen stores. Therefore, it may be useful to drink an electrolyte solution if you are urinating a lot after taking exogenous ketones, but it’s dependent upon how you feel.

Relationship between blood ketone and glucose levels: a BMS + MCT (5 g/kg) supplemented rats demonstrated a significant inverse relationship between elevated blood ketone levels and decreased blood ketone levels (r2 = 0.4314, p = 0.0203). b At week 4, BMS + MCT (10 g/kg) and MCT (10 g/kg) showed a significant correlation between blood ketone levels and blood glucose levels (r2 = 0.8619, p < 0.0001; r2 = 0.6365, p = 0.0057). Linear regression analysis, results considered significant if p < 0.05

We will go deep in the science behind this fascinating diet and then review some of the best exogenous ketone supplements out there in the market. Because without the knowledge and the right information about exogenous ketones that you can properly follow, you might never reach your goals and you may as well keep eating that mashed potato for dinner and club sandwich for lunch.
Humans in the hunter-gatherer era survived thanks to metabolic flexibility — the body’s ability to use different fuels for energy depending on the nutrients available. This adaptation was vital during a time when the source, quantity, and frequency of food was uncertain[*]. Most of the time, people were fasting, so their bodies ran on ketones, not glucose.
