Cordain admits that meat leads to plaque and increases cholesterol where plants wouldn’t. And science establishes that plaque and cholesterol lead to heart attacks and strokes. But Cordain argues that plaque alone is insufficient to cause harm. Rather, it is plaque combined with inflammation that causes heart attacks and strokes. So avoid acid, salt, legumes, wheat, starchy vegetables, dairy, oil, fatty meats, and grains because they cause inflammation. But if both science and Cordain agree that plaque is a necessary part of the heart-disease equation—and that meat causes plaque—why should we follow Paleo rather than just forgo meat?
Triglycerides are a common form of fat that we digest. Triglycerides are the main ingredient in animal fats and vegetable oils. Elevated levels of triglycerides are a risk factor for heart disease, heart attack, stroke, fatty liver disease, and pancreatitis. Elevated levels of triglycerides are also associated with diseases like diabetes, kidney disease, and medications (for example, diuretics, birth control pills, and beta blockers). Dietary changes, and medication if necessary can help lower triglyceride blood levels.
You may think hand sanitizer will zap germs and prevent you from getting sick, but it could also be making you fat. Hand sanitizer contains triclosan, which researchers have found to be an “obesogen,” meaning it could cause weight gain by disrupting your body’s hormones. A study published in the journal PLOS One found that people who had detectable levels of triclosan in their bodies were associated with a 0.9-point increase in body mass index (BMI). If you’re really worried about germs, it’s best to rely on good ol’ soap and water.
Grazing is a surprisingly good idea because it helps you avoid metabolic slowdown. "Your body will be tricked into thinking it's constantly eating, so it will never slow your metabolism down," explains Bauer. Aim for five small meals (200 to 500 calories) a day rather than three large ones. Also try not to go more than four hours without eating — if you eat breakfast at 7am, for example, have a snack at 10am, lunch at noon, another snack at 3pm and dinner at 7pm.
Shaping is a behavioral technique in which you select a series of short-term goals that get closer and closer to the ultimate goal (e.g., an initial reduction of fat intake from 40 percent of calories to 35 percent of calories, and later to 30 percent). It is based on the concept that "nothing succeeds like success." Shaping uses two important behavioral principles: (1) consecutive goals that move you ahead in small steps are the best way to reach a distant point; and (2) consecutive rewards keep the overall effort invigorated.
