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.
Another mineral you may want to supplement is potassium. While there is no concrete evidence that a dramatic potassium loss occurs on a low-carb regimen, Sondike says to ensure against problems he recommends patients use Morton's Light Salt -- a potassium chloride product that he says can add back any of this important mineral that's lost. Eating a few almonds is also a good way to supplement this mineral without adding carbs to your diet.
The short answer is no. In fact, you technically do not need to eat any carbs at all. When carbs are restricted, your body switches to using fat and ketones rather than sugar as its main energy source. Aside from your red blood cells and a small portion of your brain and kidneys, which require glucose, your cells can use fatty acids or ketones as fuel.
Glucose that isn’t immediately needed by these cells can be stored in your liver and muscles as glycogen (long chains of glucose, similar to starch in food). However, there is a limit to the amount that can be stored. Once your glycogen storage sites are full, any additional glucose from the breakdown of excess carbohydrate will be converted to fat and stored in your body.
Take a break from breakfast: If you’re not hungry, feel free to skip breakfast and just have coffee (with some milk if you want it). Many people find that within a few days of eating low-carb, high-fat meals, cravings and hunger decrease significantly. This can make it easy to skip a meal, perhaps especially breakfast. Skipping a meal is cheap, fast, and might increase the diet’s effectiveness for weight loss and diabetes. See intermittent fasting
"Your body will often shift metabolism when you do something different to it -- but it equalizes -- you see a rapid shift and a return to normal -- and the longer-term studies show normal results in this area," says Sondike. Still, he tells WebMD it's a "smart idea" to take a calcium supplement beginning at the start of your low-carb diet to safeguard against a possible deficiency. Tofu can also be a good source of calcium.
Once glucose enters your bloodstream, it causes your blood sugar to rise immediately. This prompts your pancreas to produce insulin, the hormone that allows glucose to move out of your blood and into your cells. How much your blood sugar goes up – and how long it stays elevated – depends on a number of factors, including how many carbs you eat, how much insulin you produce, and how sensitive your cells are to insulin.
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.
While eating a low-carbohydrate diet might not be the “magic bullet” to lasting weight loss for every person, it’s very helpful for most people to cut back on added sources of sugar and processed carbs. Removing foods such as bread, cereals, sweetened drinks, processed dairy and in some cases, even whole grains or starchy veggies from your diet can result in your body releasing less insulin.
Importantly, it is generally accepted that there is one component of carbs that isn’t digested and absorbed: fiber. This is because, unlike starch and sugar, your body lacks the enzymes needed to break down fiber. However, bacteria that live in your gut can digest it. After fiber passes into your colon, these gut bacteria ferment it into short-chain fatty acids, which don’t raise blood sugar and may provide health benefits.
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.
