Low-carb diets are holding steady in the weight-loss world as the top diet for losing weight. And while some research suggests that a combination of a low-calorie and low-carb diet can be effective for weight loss, if you end up going too low in carbs, you can actually make weight loss harder for yourself. There are some strong arguments regarding how many carbs in a low-carb diet actually make it effective for weight loss, but the truth is you don't have to go as low as the keto and Whole30 diets suggest to get weight-loss benefits. In this 30-day low-carb diet plan, we show you what a healthy low-carb diet for weight loss looks like, with a full month of delicious low-carb breakfast, lunch, dinner and snack ideas.
However, the more weight you want to lose, or the more your health has suffered on the SAD way of eating, the fewer carbs you may want to consume at the start of the low-carb, high-fat diet. If you stay under 20 grams of carbs a day, you will be eating a very low-carb diet or ketogenic diet, in which your body converts from burning carbs (glucose) to burning fat (ketones) for fuel. Ketogenic diets can also suppress appetite, so you end up eating less without getting hungry.
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.
The Mediterranean-style low carb diet approach, which we recommend in The Blood Sugar Diet, is a low sugar diet, low in starchy, easily digestible carbs, but packed full of disease-fighting vitamins and flavonoids. It is rich in olive oil, fish, nuts, fruit and vegetables, but also contains lots of lovely things that down the years we have been told not to eat, such as full fat yoghurt and eggs.
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.
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.

You can even start a new plan from scratch (of from pre-existing ones), tailor them completely and save them.

At the start, do not deny yourself fat. Eat enough so that you are satisfied and you do not feel hungry. That way you will soon become what is called “fat adapted” — burning fat for fuel efficiently. You will know that you are fat adapted when you do not need to eat every few hours and you no longer feel the highs and lows (“hangry” episodes) that can accompany a high carb diet.
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.
There is extensive evidence for the benefit of the Mediterranean style low carb diet, including cutting your risk of heart disease and diabetes. It has even been found to reduce risk the risk of breast cancer, compared with those on a low-fat diet. Consuming extra virgin olive oil (the fresh squeezed juice of olives) seems to be particularly beneficial when it comes to cancer, perhaps because it contains compounds such as polyphenols which are known to be anti-inflammatory.
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.
"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, especially very low-carb diets, may lead to greater short-term weight loss than do low-fat diets. But most studies have found that at 12 or 24 months, the benefits of a low-carb diet are not very large. A 2015 review found that higher protein, low-carbohydrate diets may offer a slight advantage in terms of weight loss and loss of fat mass compared with a normal protein diet.

Low-carb diets may improve high-density lipoprotein (HDL) cholesterol and triglyceride values slightly more than do moderate-carb diets. That may be due not only to how many carbs you eat but also to the quality of your other food choices. Lean protein (fish, poultry, legumes), healthy fats (monounsaturated and polyunsaturated) and unprocessed carbs — such as whole grains, legumes, vegetables, fruits and low-fat dairy products — are generally healthier choices.

However, the more weight you want to lose, or the more your health has suffered on the SAD way of eating, the fewer carbs you may want to consume at the start of the low-carb, high-fat diet. If you stay under 20 grams of carbs a day, you will be eating a very low-carb diet or ketogenic diet, in which your body converts from burning carbs (glucose) to burning fat (ketones) for fuel. Ketogenic diets can also suppress appetite, so you end up eating less without getting hungry.
The studies done on ketosis and endurance sports performance paint a pretty clear picture – it helps.  One of the most detailed studies on fat utilisation and performance (compared to a standard carb diet) was named the FASTER study - the results found that those who were on a ketogenic type diet had more mitochondria than the control group, lower oxidative stress, lower lactate load and that the fat adapted and fuelled athletes could function off fat for a much higher intensity than the non-fat adapted counter parts.

In addition to keeping you adequately hydrated -- which can also help alleviate constipation -- drinking lots of water can also help offset still another low-carb diet problem: bad breath. The ketones produced during the diet can lead to what is sometimes described as a fruity odor although it is often described as having an almost "chemical" odor similar to acetone or nail polish remover.

In general, a low-carb diet focuses on proteins, including meat, poultry, fish and eggs, and some nonstarchy vegetables. A low-carb diet generally excludes or limits most grains, legumes, fruits, breads, sweets, pastas and starchy vegetables, and sometimes nuts and seeds. Some low-carb diet plans allow small amounts of certain fruits, vegetables and whole grains.
Healthy fats & oils are back in too: Eating fat does not automatically clog the blood vessels in the way that poring oil down the drain will eventually block the drain. You make your own cholesterol and lipids and are more likely to increase your levels of the more damaging Very Low Density Lipoprotein (VLD), which is made in the liver when you eat a high carbohydrate diet.

Reduce daily net carb intake to less than 20 grams: Although it’s possible that you may not need to be this strict, eating fewer than 20 grams of net carbs every day virtually guarantees that you’ll achieve nutritional ketosis. What does 20 grams of carb look like? Use our visual guide to find out, or simply try our keto recipes and meal plans that limit carbs to less than 20 grams per day.
