                                According to a 2019 meta-analysis, a Very Low-Calorie Ketogenic Diet (VLCKD) of under 800 kcal/day can effectively induce ketosis for rapid weight loss in selected patients. This confirms that you can go into ketosis on 800 calories, but it is an extreme and highly restrictive approach not suitable for general use.
