Appetite regulation: One of the first things people often notice when they’re in ketosis is that they’re no longer hungry all the time. In fact, research has shown that being in ketosis suppresses appetite. One study looked at people who lost weight by following a ketogenic diet for eight weeks and then reintroduced small amounts of carbs. The researchers reported that levels of ghrelin (the “hunger hormone”) were suppressed in those who remained in ketosis, whereas those who were no longer in ketosis had higher ghrelin levels.
Try to be patient. Although some people get into ketosis relatively quickly, it may take others a while. Unfortunately, people who are insulin resistant often seem to have a longer journey. Put in a solid month of consistent keto eating, and try to ramp up your physical activity, if possible. Within four weeks, you should definitely be in ketosis and experiencing its benefits.
Another benefit of ketosis is an unlimited supply of energy for your body. Your body can only store a certain amount of carbohydrates in your liver and your muscles, but there's no limit to the amount of fat it can store. According to a report published in Nutrition Reviews in 2018, your body can store a total of 600 grams of glycogen, which is divided between the liver and your muscles. On the other hand, it can store as much fat as you give it.
Although it’s true that your brain has high energy demands and requires some glucose, when you’re in ketosis, there are plenty of ketones to supply a good portion of its fuel. Fortunately, your liver will always make the small amount of glucose your brain needs, even under conditions of complete starvation. This process, known as gluconeogenesis (literally “making new glucose”), can also provide glucose for other structures that need it, such as the red blood cells and a portion of the kidneys.
Con: Results can vary depending on how much fluid you drink. By drinking more water, you dilute the concentration of ketones in the urine and thus a lower level of ketones will be detected on the strips. The strips don’t show a precise ketone level. Finally, and most importantly, as you become increasingly keto-adapted and your body reabsorbs ketones from the urine, urine strips may become unreliable, even if you’re in ketosis.

Finally, a feasibility study was done on 10 cancer patients in 2012. All patients followed a ketogenic diet for 28 days after exhausting every other cancer treatment option. The results of the study found that 1 had a partial remission of their cancer, 5 stabilized and 4 continued progressing. It’s important to remember that these individuals had tried all other forms of cancer treatment. 60% of these individuals then stalled or improved their cancer rates by following a ketogenic diet for 4 weeks.

Ketosis has been shown to have anti-inflammatory properties while also assisting with pain relief. Reducing glucose metabolism influences pain, so this could be one potential mechanism of action. In the review The Nervous System and Metabolic Dysregulation: Emerging Evidence Converges on Ketogenic Diet Therapy the authors look at numerous ways that a ketogenic diet can assist with pain and inflammation.

A ketogenic diet – due to its extremely low carb intake – can help address insulin resistance and in turn help with suffers of PCOS. In fact, a pilot study has concluded that a ketogenic diet led to a significant improvement in body weight, fasting insulin, testosterone markets and LH/FSH ratio in woman with PCOS. Two woman even became pregnant during the study.
One of the most commonly reported disadvantages of a ketogenic diet is constipation. The diet requires you to eliminate most sources of carbohydrates, which also happen to be some of the foods with the highest amount of fiber. As a result, digestion can slow down and leave you feeling uncomfortable, especially in the beginning stages as your body adjusts.
Perhaps the biggest anecdotal evidence on ketosis slowing down MS is the story of Dr. Terry Wahls. Dr. Wahls overcame being wheelchair bound after trying various drugs and conventional therapies without success. Eventually, she turned to dietary changes – including following a ketogenic diet – and a lot of her symptoms disappeared. She now lives an active life, riding horses and going on long treks. She shares her story and the protocol she developed in the book The Whals Protocol: A Radical New Way to Treat All Chronic Autoimmune Conditions Using Paleo Principles.

Ketoacidosis occurs mainly in people with type 1 diabetes if they do not take insulin. In diabetic ketoacidosis (DKA), blood sugar and ketones rise to dangerous levels, which disrupts the blood’s delicate acid-base balance. People in ketoacidosis feel extremely ill and experience profound dehydration, vomiting, abdominal pain, and weakness. DKA requires hospitalization so that IV fluids and insulin can be given to gradually and safely lower blood sugar.


Glucose is stored in your liver and released as needed for energy. However, after carb intake has been extremely low for one to two days, these glucose stores become depleted. Your liver can make some glucose from amino acids in the protein you eat via a process known as gluconeogenesis, but not nearly enough to meet the needs of your brain, which requires a constant fuel supply.

Getting into ketosis on a ketogenic diet is not a black or white thing. It’s not like you’re either in ketosis or out of ketosis. Instead, you can achieve different degrees of ketosis. The definition of “optimal” ketosis my vary depending on your goals. For instance, treating seizures may require a higher ketone level, where as losing weight or improving blood sugar may depend less on the degree of elevation. This chart demonstrates this visually. The numbers below refer to values when testing blood ketone levels.
For decades we’ve been told that fat is detrimental to our health. Meanwhile low-fat “diet” products, often full of sugar, have flooded supermarket shelves. This has likely been a major mistake, that coincided with the start of the obesity epidemic. While this doesn’t prove causation, it’s clear the low-fat message didn’t prevent the obesity increase, and it is possible it contributed.

Most of us LOVE dairy products in all shapes and forms, but it’s possible that skipping or reducing them in your diet could speed up your weight loss and be beneficial for your health. This is because dairy products contain not only milk sugar (lactose), but also milk protein (casein), which stimulates insulin secretion more than many other types of protein, and can trigger overeating.
