Josh Axe, a doctor of natural medicine and clinical nutritionist, estimates that about 25% of people who try a ketogenic diet experience these symptoms, with fatigue being the most common. “That happens because your body runs out of sugar to burn for energy, and it has to start using fat,” he says. “That transition alone is enough to make your body feel tired for a few days.”
The keto diet (also known as ketogenic diet, low carb diet and LCHF diet) is a low carbohydrate, high fat diet. Maintaining this diet is a great tool for weight loss. More importantly though, according to an increasing number of studies, it helps reduce risk factors for diabetes, heart diseases, stroke, Alzheimer’s, epilepsy, and more1-6.On the keto diet, your body enters a metabolic state called ketosis. While in ketosis your body is using ketone bodies for energy instead of glucose. Ketone bodies are derived from fat and are a much more stable, steady source of energy than glucose, which is derived from carbohydrates.
When the body is expending more energy than it is consuming (e.g. when exercising), the body's cells rely on internally stored energy sources, such as complex carbohydrates and fats, for energy. The first source to which the body turns is glycogen (by glycogenolysis). Glycogen is a complex carbohydrate, 65% of which is stored in skeletal muscles and the remainder in the liver (totaling about 2,000 kcal in the whole body). It is created from the excess of ingested macronutrients, mainly carbohydrates. When glycogen is nearly depleted, the body begins lipolysis, the mobilization and catabolism of fat stores for energy. In this process, fats, obtained from adipose tissue, or fat cells, are broken down into glycerol and fatty acids, which can be used to generate energy. The primary by-products of metabolism are carbon dioxide and water; carbon dioxide is expelled through the respiratory system.
A meta-analysis of randomized controlled trials by the international Cochrane Collaboration in 2002 concluded that fat-restricted diets are no better than calorie-restricted diets in achieving long term weight loss in overweight or obese people. A more recent meta-analysis that included randomized controlled trials published after the Cochrane review found that low-carbohydrate, non-energy-restricted diets appear to be at least as effective as low-fat, energy-restricted diets in inducing weight loss for up to 1 year. These results can be understood because weight loss is mainly governed by daily caloric deficit and not by the particular foods eaten. However, when low-carbohydrate diets to induce weight loss are considered, potential favorable changes in triglyceride and high-density lipoprotein cholesterol values should be weighed against potential unfavorable changes in low-density lipoprotein cholesterol values."
Many studies have focused on diets that reduce calories via a low-carbohydrate (Atkins diet, Scarsdale diet, Zone diet) diet versus a low-fat diet (LEARN diet, Ornish diet). The Nurses' Health Study, an observational cohort study, found that low carbohydrate diets based on vegetable sources of fat and protein are associated with less coronary heart disease. The same study also found no correlation (with multivariate adjustment) between animal fat intake and coronary heart disease (table 4). A long term study that monitored 43,396 Swedish women however suggests that a low carbohydrate-high protein diet, used on a regular basis and without consideration of the nature of carbohydrates or the source of proteins, is associated with increased risk of cardiovascular disease.
Plan. Buy your food ahead of time so you aren't tempted by grocery shopping while hungry. Hunger destroys willpower. Buy enough food to last you through the whole diet so that you can avoid the temptation of shopping during the diet. Also, get rid of any junk food you have at home. Don’t just lock it in a closet, give it away and get it out of your house entirely. You don’t want anything to lead you astray while you’re on your diet and feeling very hungry. If you know there’s no junk food at home, you won’t tempt yourself as much. Dieting is hard. Don’t make it harder by knowing that junk food is close-by.
