• Reducing appetite — Constant hunger can cause you to consume more calories than you can burn, which can eventually lead to weight gain. A ketogenic diet can help you avoid this problem because reducing carbohydrate consumption can reduce hunger symptoms. In one study, participants who were given a low-carbohydrate diet had reduced appetites, helping them lose weight easier.2
How: Lie back on a flat bench holding a barbell in the rack above you with a shoulder-width, overhand grip. Lift the bar off the rack and position it above your chest with arms fully extended. From the starting position, breathe in and lower the bar slowly until it skims the middle of your chest. Push the bar back to the starting position explosively as you breathe out. That’s one rep.
Increases in cholesterol levels need discussion too. We do see temporary increases in cholesterol levels often as individuals transition onto a ketogenic diet. However, when you examine lipid particle size (a more important way to look at the cardiovascular risks), the risk pattern doesn’t seem to increase with a ketogenic diet. Harvard Health has written about lipid particle size here before: http://www.health.harvard.edu/womens-health/should-you-seek-advanced-cholesterol-testing-
• Cyclic ketogenic diet (CKD) — Whereas TKD is focused on fitness enthusiasts, CKD is focused more on athletes and bodybuilders. In CKD, you cycle between a normal ketogenic diet, and a short period of high carb consumption or "re-feeds."8 The idea here is to take advantage of the carbohydrates to replenish the glycogen lost from your muscles during athletic activity or working out.9
Physicians of ancient Greece treated diseases, including epilepsy, by altering their patients' diet. An early treatise in the Hippocratic Corpus, On the Sacred Disease, covers the disease; it dates from c. 400 BC. Its author argued against the prevailing view that epilepsy was supernatural in origin and cure, and proposed that dietary therapy had a rational and physical basis.[Note 3] In the same collection, the author of Epidemics describes the case of a man whose epilepsy is cured as quickly as it had appeared, through complete abstinence of food and drink.[Note 4] The royal physician Erasistratus declared, "One inclining to epilepsy should be made to fast without mercy and be put on short rations."[Note 5] Galen believed an "attenuating diet"[Note 6] might afford a cure in mild cases and be helpful in others.[11]
Yes, you lose weight when you cut calories, but pounds lost aren’t always fat. Some of your weight loss may also come from muscle tissue. Cyclists that diet often end up thinner, but risk becoming slower and weaker on the bike. As pioneering diet expert Covert Bailey once wrote, “When someone says that they lost 20 pounds, the key question is: 20 pounds of what?” Some dieters can end up having a higher percentage of body fat even as they lose weight. And don’t forget that muscle burns calories. The more muscle volume you have, the more calories your body can burn—even when you’re just lying on the couch.
