Beginners Guide to Low Carb Lifestyle

Beginners Guide to Low Carbohydrate Lifestyle

Have you put on weight during the covid lockdown in 2020? Lacking exercise due to lockdown? 

Too much baking, chocolate, treats, snacks? Need to loose weight? You could be surprised that weight loss is 80% with diet and only 20% with exercise. Imagine a diet that can help you loose weight, reduce your risk of diabetes and heart disease, and many other conditions, improve your energy level, reduce hunger and may even get you off your medications prescribed by your doctor. This diet is also sustainable. It is not a diet. It is a lifestyle. The diet recommended by doctors that understand metabolic conditions are Low Carbohydrate way of eating. We promote eating real food. Real food is meat, vegetables, whole foods, dairy products, poultry, seafood, eggs and healthy fat like nuts, avocado. Real foods does not include packaged foods, refined carbohydrates, refined or artificial sweeteners and artificial seed oils. Traditional ideas about weight loss, that is, counting calories, does not work. It requires lots of willpower. Eating less by reducing calories leaves you hungry. Moving more also leave you hungry. Whilst weight will drop off, it is often regained when hunger takes hold and you start eating normal again. Quite often you regain more than you loose.To understand how to loose weight, it is important to understand the hormones. Insulin. Insulin is a hormone made by the pancreas to move glucose to become fat for storage. If your blood stream has high glucose all the time, more and more insulin is produced to store these glucose to fat. These insulin subsequently starts to work less effective, developing insulin resistance. Don’t forget, eating starches, including bread, pasta, rice, etc, breaks down into glucose as it enters the body. 

When your body has insulin resistance, body fat is stored away, unable to be used. You constantly feel hungry. The more carbohydrate you eat, the more insulin is made and the less effective insulin works. To reduce insulin resistance, we need to help the hormone work again by reducing insulin in the blood stream. To do this, we need to reduce carbohydrate intake. We also need to give the body a break by stop eating constantly. A low carb diet, combined with time restricted eating or intermittent fasting is a very powerful tool to reduce insulin resistance, and subsequently loosing weight. It is recommended to start with low carb eating first. After a few weeks of getting used to eating low carb eating, we can also try time restricted eating and even intermittent fasting. Time restricted eating means eating breakfast, lunch and dinner and not snacking between. Milk and sugar, for example tea or coffee is also considered a snack as the calories in these drinks will raise insulin. Intermittent fasting means some day, you can go longer without meals, eg. 16 hour fast and eating in an 8 hour window, e.g. skip breakfast, have lunch at 11am and have finish dinner before 7pm.
