There are so many tricks, shortcuts, and gimmicks out there on achieving optimal ketosis – I’d suggest you don’t bother with any of that. Optimal ketosis can be accomplished through dietary nutrition alone (aka just eating food). You shouldn’t need a magic pill to do it. Just stay strict, remain vigilant, and be focused on recording what you eat (to make sure your carb and protein intake are correct).
Your current cholesterol levels l is higher than I would personally feel comfortable with. I would consider making a few dietary changes (i.e., increasing fiber and net carbs, reducing saturated fat, and increasing protein), especially given your lack of improved cognition and decreased ability to work out. I wish you the best of luck going forward. - Franziska
Chickpeas are naturally high in carbs — a single cup contains 45 grams of carbohydrates.31 However, you can modify the recipe to make it more nutritious. Try this recipe from Pete Evans, which replaces the chickpeas with beetroot.32 Beware, though, that beets have the highest sugar content of all vegetables, so consume them in very controlled amounts.
The premise of the ketogenic diet for weight loss is that if you deprive the body of glucose—the main source of energy for all cells in the body, which is obtained by eating carbohydrate foods—an alternative fuel called ketones is produced from stored fat (thus, the term “keto”-genic). The brain demands the most glucose in a steady supply, about 120 grams daily, because it cannot store glucose. During fasting, or when very little carbohydrate is eaten, the body first pulls stored glucose from the liver and temporarily breaks down muscle to release glucose. If this continues for 3-4 days and stored glucose is fully depleted, blood levels of a hormone called insulin decrease, and the body begins to use fat as its primary fuel. The liver produces ketone bodies from fat, which can be used in the absence of glucose. 
Also, consider supplementing with the amino acid leucine, as it can be broken down directly into acetyl-CoA, making it one of the most important ketogenic amino acids in the body. While most other amino acids are converted into glucose, the acetyl-CoA formed from leucine can be used to make ketone bodies. It’s also present in keto friendly foods like eggs and cottage cheese.
