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.

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.
You can see the results, too. In January 2015, the Journal of Nutrition conducted two studies comparing lower-carb and low-fat diets, finding that of the two approaches, going lower carb helped people shave off more visceral fat, a type of belly fat that hugs organs and is linked to disease. (3) A meta-analysis published in June 2016 in Obesity Reviews also concluded that in obese people, a low-carb diet reduced fat over the course of a year (but not body weight), with the greatest benefits seen in a very-low-carb diet.

Exercise reduces appetite. It is good for general cardiovascular fitness and strength, but is a hard way to lose weight. If you find it hard to exercise, simply moving more has significant health benefits and can increase your metabolic rate. Get up and move around every half hour, walk don’t take the bus, stairs instead of lift…Get a pedometer and try to increase your steps by 10% each week.

Research funded by an American company also found that some people with type 2 diabetes who followed a programme that included a low-carb eating plan were in remission after two years. Participants in the study were supported to restrict their intake of carbs, initially to less than 30g per day and then gradually increasing the amount, based on personal tolerance and health goals. 

As low-carb dietitian Franziska Spritzler, RD, CDE, who’s based in Orange County, California, points out, when you cut back on carbs, blood sugar and insulin levels generally go down, which can be a good thing for some people. “Carbs are broken down into glucose, which raises your blood sugar and prompts your pancreas to produce insulin to drive sugar into your cells,” says Spritzler. “When you’re overweight or obese, your blood sugar goes up and your pancreas sends out insulin, but your cells may not be responsive, leading your pancreas to overproduce insulin,” she says. High insulin increases hunger and prompts fat storage, she explains.

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.
Low-carb diets may help prevent or improve serious health conditions, such as metabolic syndrome, diabetes, high blood pressure and cardiovascular disease. In fact, almost any diet that helps you shed excess weight can reduce or even reverse risk factors for cardiovascular disease and diabetes. Most weight-loss diets — not just low-carb diets — may improve blood cholesterol or blood sugar levels, at least temporarily.
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.
