The popular low-carb diets (such as Atkins or Paleo) modify a true keto diet. But they come with the same risks if you overdo it on fats and proteins and lay off the carbs. So why do people follow the diets? "They're everywhere, and people hear anecdotally that they work," McManus says. Theories about short-term low-carb diet success include lower appetite because fat burns slower than carbs. "But again, we don't know about the long term," she says. "And eating a restrictive diet, no matter what the plan, is difficult to sustain. Once you resume a normal diet, the weight will likely return."
The notion that metabolic syndrome, or its surrogate markers hyperinsulinemia and insulin resistance, antedate and contribute to the pathogenesis of coronary heart disease, diabetes, and at least some cases of hypertension was proposed many years ago.21,35 Coronary heart disease in the setting of metabolic syndrome can to a great extent be attributed to dyslipidemia (increased dense LDL cholesterol, diminished HDL cholesterol, and hypertriglyceridemia)231 as well as to elevations in blood pressure and blood glucose and the presence of a procoagulant, proinflammatory state.22,228 In addition, some studies suggest that hyperinsulinemia and insulin resistance, as well as hyperglycemia, may be independent risk factors.51 Whether elevated FFA levels or a dysregulation of intracellular fatty acid metabolism contribute to atherosclerosis by directly altering the function of endothelium (see the section entitled “Vascular Endothelial Cells and Atherogenesis”) or other cells in the vascular wall remains to be determined. Relevant to this discussion, low levels of adiponectin are associated with an increased risk for coronary heart disease in humans,155 whereas, as noted earlier, overexpression of adiponectin or its globular subunit diminishes the severity of atherosclerosis in ApoE–/– mice.232,233
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]
Even small changes to your diet can make a difference when you're trying to lose weight, so don't feel like you have to follow a strict regimen or cut out entire food groups. If you like to bake, try low-calorie substitutions in your recipes. Cooking at home more often can help you lose weight, especially if you look for ways to reduce fat and calories in your meals. As you make changes like these, you may even find that you enjoy healthy eating.

This is a wealth of information. My husband and I are starting the keto diet tomorrow and I knew nothing about it. When I sat down to look up information about it, I found this. Thank you! This is everything I need to know in one place. We are not as healthy as we’d like to be and I am optimistic this will help us obtain our goals, along with an exercise plan.

Metabolic syndrome is a collection of heart disease risk factors that increase your chance of developing heart disease, stroke, and diabetes. The condition is also known by other names including Syndrome X, insulin resistance syndrome, and dysmetabolic syndrome. According to a national health survey, more than 1 in 5 Americans has metabolic syndrome. The number of people with metabolic syndrome increases with age, affecting more than 40% of people in their 60s and 70s.
