Severely restricting carbohydrates to less than 0.7 ounces (20 grams) a day can result in a process called ketosis. Ketosis occurs when you don't have enough sugar (glucose) for energy, so your body breaks down stored fat, causing ketones to build up in your body. Side effects from ketosis can include nausea, headache, mental and physical fatigue, and bad breath.
Otherwise in a nutshell ketosis can be defined as a “metabolic state that happens when you consume a very low carb, moderate protein, high fat diet (or fast for extended periods) that causes your body to switch from using glucose as it’s primary source of fuel, to running off ketones. Ketones themselves are produced when the body burns fat, and they’re primarily used as an alternative fuel source when glucose isn’t available.” (Keto Clarity)
If you want to cut costs even more you can replace the avocado in the tuna salad (if you are not lucky enough to find avocados on sale) with more vegetables. A drizzle of some extra olive oil on the salad will compensate for the reduction of fat from the avocado. You can also substitute any of cheeses in the recipes for other types of cheese that you may find on sale.
There is also exciting early research suggesting that ketosis may be beneficial for many other conditions, such as reducing the frequency and severity of migraine headaches, reversing PCOS, perhaps enhancing conventional brain cancer therapies, possibly slowing down the progression of Alzheimer’s disease, along with potentially helping people live longer, healthier lives. Although higher quality research is needed to confirm these effects, much of the early research is very encouraging.
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.
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.
Over 3 mmol/l is higher than necessary. It will probably achieve neither better nor worse results than being at the 1.5–3 level. Higher numbers can also sometimes mean that you’re not getting enough food (“starvation ketosis”). In people with type 1 diabetes, ketone levels over 3.0 mmol/L can be caused by a severe lack of insulin that requires urgent medical attention.
Although oil or butter is high in calories, it is very slowly digested and surprisingly does not significantly increase your blood sugar. It makes vegetables taste better and can improve the absorption of certain vitamins and the essential vitamins A, D, E & K are only found in certain fats & oils. Avoid foods containing trans-fats (usually processed foods). Use oils such as olive oil, rapeseed oil or coconut oil. It also helps you feel full for longer so be more generous

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.


"One of the primary places where you are going to see metabolic changes on any kind of diet is in your gastrointestinal tract -- and that can include a change in bowel habits often experienced as constipation," says Sondike, who is also credited with conducting the first published, randomized clinical trial on low-carb diets. The reason, Sondike tells WebMD, is that most folks get whatever fiber they consume from high-carb foods such as bread and pasta. Cut those foods out, and your fiber intake can drop dramatically, while the risk of constipation rises.

Low-carb diets are holding steady in the weight-loss world as the top diet for losing weight.
