From a calorie standpoint symptoms vaginal cancer topamax 200mg free shipping, low-fat cookies are just as bad for your waistline as high-fat cookies medicine kidney stones buy cheap topamax 200 mg on line. Second symptoms 24 purchase topamax 100mg online, most people eat a larger portion size of low-fat foods than they do of high-fat foods, possibly under the false belief that low fat equals low calorie. If you were scooping some low-fat ice cream into a bowl, would you scoop out the same amount as you would high-fat ice cream? High-carb, low-fat foods are not as satisfying as their original counterparts. In the end, many people consume more calories on a low-fat diet than when on a high fat diet. NOT ALL FATS ARE BAD Not only was cutting fat out of the diet not the answer, but it was shortsighted. There are many different types of fat, rang- ing from the artery-clogging saturated fats found in fatty cuts of meat and whole milk to the processed trans fats found in commercially baked goods and margarine (which, by the way, may be worse for your health than but- ter)—and often in movie popcorn—to the heart-friendly unsaturated fats found in certain vegetables, nuts, flaxseed, and fish. When researchers compared diets rich in maize (corn) oil, beef tallow, and fish oil, they found that rats who ate the diet rich in fish oil gained less weight than rats on the beef or corn oil diet. Other studies show that replacing saturated and trans fats with unsaturated fats results in weight loss, even when total caloric intake is held constant. Eating unsaturated fats instead of saturated or trans fats lowers your unhealthy LDL cholesterol and lowers levels of triglycerides (a nasty type of blood fat). For many years, scientists told us that to lose weight, you had to eat fewer calories than you burned. Some of the calories you eat are more likely to lead to weight gain than others. For THE ULTIMATE BODY NUTRITION PLAN 115 TLFeBOOK instance, certain foods use more energy during the process of digestion than others. Any time you eat, your body must burn calories in order to break the food down, push it through your intestines, and absorb its nutrients. Researchers also know that high-protein foods tend to cause a slow, even rise in blood sugar, whereas carbohydrates cause blood sugar lev- els to spike. The slower your blood sugar rises, the less of the hormone insulin your pancreas must secrete to clear the sugar out of your blood. This is why you feel hungry not long after eating a bagel, even though that bagel contains roughly 400 calories. Highly processed carbohydrates—the type you find in boxes, shrink- wrap, and other packaging in the middle aisles of the grocery store—are about the worst thing you can eat when it comes to losing weight and look- ing your best. These carbs are all made from white flour and white sugar, both of which are highly processed. To create white flour, the processor starts with wheat, an otherwise healthy food. The lack of fiber and high number of calories in processed car- bohydrates cause them to hit your bloodstream faster than just about any other food you can eat. Researchers have tested hundreds of foods and ranked them for their speed in spiking blood sugar levels on a scale known as the glycemic index. Foods that rank high on the index, such as table sugar and potatoes, spike blood sugar quickly. Foods that rank low on the index, such as beans and most vegetables, cause a slow, even rise in blood sugar. On my Ultimate New York Body Plan, you will eat only low-glycemic carbs for two weeks. After two weeks, you will focus most of your diet on low-glycemic carbs, reserving high-glycemic carbs for special occasions and treats. So now you can see why this nutrition plan is rich in protein and very low in carbohydrates. The protein in this diet will help you in a number of ways: 116 THE ULTIMATE NEW YORK BODY PLAN TLFeBOOK I PRESERVING AND BUILDING MUSCLE MASS Usually when you cut back on calories, your body responds by cannibalizing muscle tissue and spar- ing fat tissue.

Symptoms of myocardial ischemia occur when the myocardium does not get an adequate supply of oxy- genated blood. Symptoms of congestive heart failure occur when the increased cardiac workload is prolonged. Cardiovascular prob- lems are more likely to occur in clients who are elderly or who al- ready have heart disease. With propylthiouracil and methimazole, observe for: (1) Hypothyroidism—bradycardia, congestive heart fail- ure, anemia, coronary artery and peripheral vascular dis- ease, slow speech and movements, emotional and mental dullness, excessive sleeping, weight gain, constipation, skin changes, and others (2) Blood disorders—leukopenia, agranulocytosis, hypo- Leukopenia may be difficult to evaluate because it may occur with prothrombinemia hyperthyroidism and with antithyroid drugs.

With iodine preparations, observe for: Adverse effects are uncommon with short-term use. Drugs that increase effects of thyroid hormones: (1) Activating antidepressants (eg, bupropian, venlafaxine), These drugs may cause CNS and cardiovascular stimulation when adrenergic antiasthmatic drugs (eg, albuterol, epinephrine), taken alone. When combined with thyroid hormones, excessive nasal decongestants cardiovascular stimulation may occur and cause myocardial ischemia, cardiac dysrhythmias, hypertension, and other adverse cardiovascular effects. Excessive CNS stimulation may produce anxiety, nervousness, hyperactivity, and insomnia. Drugs that decrease effects of thyroid hormones: (1) Antacids, cholestyramine, iron, sucralfate Decrease absorption of levothyroxine; give levothyroxine 2 hours before or 4 to 6 hours after one of these drugs (2) Antihypertensives Decrease cardiac stimulating effects (3) Estrogens, including oral contraceptives containing Estrogens increase thyroxine-binding globulin, thereby increasing estrogens the amount of bound, inactive levothyroxine in clients with hypo- thyroidism. This decreased effect does not occur in clients with adequate thyroid hormone secretion because the increased binding is offset by increased T4 production. Women taking oral contra- ceptives may need larger doses of thyroid hormone replacement than would otherwise be needed. It is used in hyperthyroidism to reduce tachycardia and other symptoms of excessive cardiovascular stimulation.
