Urine Strips: When tested in urine, these strips will elicit a color change based on the level of ketones, namely acetoacetate, which is present in the urine. It is important to note that acetoacetate is different than the ketones present in the blood, namely, beta-hydroxybutyrate (βHB). Due to its nature, urine ketone testing may be a sufficient initial method to test ketone production; however, it is not the ideal method for determining the utilization of these ketone bodies, especially once “keto-adapted.”
But people who started following the keto diet noticed weight loss for a few reasons: When you eat carbs, your body retains fluid in order to store carbs for energy (you know, in case it needs it). But when you’re not having much in the carb department, you lose this water weight, says Warren. Also, it's easy to go overboard on carbohydrates—but if you're loading up on fat, it may help curb cravings since it keeps you satisfied.
Just because you're not eating all your fave carb-y foods, that doesn't mean you're going to go hungry. You'll be loading up on healthy fats (like olive oil and avocado), along with plenty of lean protein like grass-fed beef and chicken, and leafy greens or other non-starchy veggies. (Check out this printable keto diet grocery list, plus this additional comprehensive list of keto foods recommended by nutritionists, to get started.)

If you start at 25g of net carbs a day, you can slowly increase to 50g as you lose weight. Once you reach your goal, you can increase your carbs as you see how they affect your weight. If you eat fruit for a week and gain weight, cut back. You have to figure out what works best for you. Ketosis can be maintained with as many as 100g of carbs each day.
In pediatric patients whose seizures could not be treated with these anti-epileptic drugs, a ketogenic diet was able to reduce seizures by more than 50% in 54% of the young patients tested, with 10% of the cohort becoming seizure-free after one year on the diet.[28] Since this study, numerous additional studies have shown this modality to be effective for children and adults with epilepsy. Results of ketogenic diet–driven studies have included 55% of patients seeing a reduction in seizures by more than 50%,[29] and 27% of patients seeing a 90% or greater reduction in seizures with many entering into complete remission.[30]
Also make sure that you know what foods have mostly carbs, fat, and protein, so you can make the right choices. For instance, it’s not just bread, pasta, chips, cookies, candy, and ice cream that contain carbs. Beans may contain protein, but they’re also very high in carbohydrates. Fruit and veggies also mostly contain carbs. The only foods that don’t contain carbs are meat (protein) and pure fats, like butter and oils (including olive oil and coconut oil).
Cognitive Enhancement: Ketones may be the preferred fuel source for the brain. Due to the brain’s preference to uptake and utilize ketones as fuel it is very common for individuals to report an increase in cognitive performance. This is even more common in individuals with some degree of insulin resistance, as their brain is likely unable to effectively utilize glucose as a sole fuel source due to the resistance.
Ketosis takes some time to get into – about two weeks of low carb eating is required for the initial adaptation. During this time there will be bouts of sluggishness, fatigue, headaches, and some gastrointestinal issues as you adapt, often referred to as “keto flu“. Proper electrolyte intake will correct most of these issues. In addition, the “diet” aspect of this ketogenic diet plan – that is, the caloric restriction – shouldn’t be worried about. Weight loss will come as your body regulates appetite as it the addiction to sugar and processed food lessens, so restricting calories during the initial two weeks isn’t recommended.
Eggs are a healthy, nutrient-dense food that has been incorrectly maligned for years. Cholesterol in food doesn’t increase cholesterol in your blood, so eat eggs liberally – they’re packed with protein and lutein, and they fill you up for hours. Make a healthy omelet with some cheddar, crumbled breakfast sausage, and shredded spinach and you’re already looking at over 30g of protein, just for breakfast! Spinach is a great source of magnesium and potassium, too. Add some sea salt and you’ve got a big dose of electrolytes that are so vital to maintaining energy and staving off headaches.

You’ll quickly find that salads are your friend when in ketosis, and for a good reason: they provide lots of food to fill you up, but they’re not going to bog you down. A bed of spinach with some red onion, bacon, a little tomato, and a hot sauce vinaigrette is quick and delicious. Add in some protein – perhaps that leftover salmon from day 1 – and you’ve got a complete, healthy lunch.
People use a ketogenic diet most often to lose weight, but it can help manage certain medical conditions, like epilepsy, too. It also may help people with heart disease, certain brain diseases, and even acne, but there needs to be more research in those areas. Talk with your doctor first to find out if it’s safe for you to try a ketogenic diet, especially if you have type 1 diabetes.
You’re transitioning. Your body is equipped to process a high intake of carbs and a lower intake of fat. Your body needs to create enzymes to be able to do this. In the transitional period, the brain may run low on energy which can lead to grogginess, nausea, and headaches. If you’re having a large problem with this, you can choose to reduce carb intake gradually.
Unfortunately, there’s no long-term data on ketogenic diets versus other diets. In a 2015 Italian study, those on a ketosis diet lost 26 pounds in three months. About half of the participants stayed on the diet for a year but lost little additional weight in the next nine months. People in a 2014 Spanish study who followed a very-low-calorie ketogenic diet lost an average of 44 pounds in a year—but a third of them dropped out, possibly because it was too hard to maintain.
I would love to share your journey on my blog. If you are planning to start this keto diet, please take before pictures, progress pictures, keep a food diary, and keep track of your weight and measurements. Then when you are ready maybe at your halfway point, or once you reach your goal weight, you can send me your results for me to share with others.
