What we do know, based on carefully conducted laboratory testing of overweight men, is that going keto probably doesn't help burn more body fat than a regular regimen. Instead, it forces people to dramatically curb their sugar intake (remember, sugar is 100% carbohydrate) and kick processed foods to the curb. Those are both good habits for overall health and blood-sugar levels, and they can help reduce your likelihood of developing cancer.
When you eat a ketogenic diet, you switch your body’s fuel source to fat rather than the body’s usual source, glucose (1). From this fuel source switch, the hunger hormone, Ghrelin, is reduced which causes your appetite to decrease (1). Because of the reduction in appetite, it is easier to adopt an intermittent fasting approach or an approach that lessons unwanted eating behavior outside your desired hours (AKA curbs the late night munchies). Therefore, I recommend eating 4 bigger meals rather than 6 small meals on a Ketogenic Meal Plan.
Ketones are triggered by an absence of carbohydrates and sugar. There are specific steps to take to get your body into ketosis, but essentially, when carbohydrates are eliminated, the body will transfer over to using ketones. But I don’t recommend removing carbohydrates completely because I want you to be consuming lots of vegetables. One reason it is so crucial to take in lots of vegetables, and especially lots of vegetables high in potassium, such as kale, beet greens and collard greens, is because it will help you keep all this fat you’re dumping off the body off your liver. You can get a fatty liver when you start dropping lots of weight, as you will once you begin running on ketones instead of glucose. So think VEGETABLE CARBOHYDRATE ONLY.
It can be tricky calculating the precise kind of diet that leads to a long life. Part of the problem is that (thankfully) we don't live our lives in highly controlled laboratory conditions. Until that terrifying day arrives and we all become well-studied lab rats, we have to rely on long-term observational data, usually in the form of surveys, to know more about which diets are the best long-term plans.
When you eat foods high in carbohydrates and fat, your body naturally produces glucose. Carbohydrates are the easiest thing for the body to process, and therefore it will use them first – resulting in the excess fats to be stored immediately. In turn, this causes weight gain and health problems that are associated with high fat, high carbohydrate diets (NOT keto).
Following the ketogenic diet can be safe in the short term but it does come with health concerns. 'It's not something that I recommend for the general population for the long-term,' says Dr Barclay. 'By drastically cutting out carbohydrate-containing foods, you'll miss out on the nutritional benefits of healthy choices like whole grains, fruit, starchy vegetables, and legumes such as beans, chickpeas and lentils.'
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).
