Vitamin D: Some experts think that sleep disorders have risen to epidemic levels for one major reason: a widespread vitamin D deficiency, says Dr. Gottfried. That's not exactly ideal, since adequate sleep is critical for your metabolism and actually achieving healthy, natural weight loss. Dr. Gottfried says it's best to aim for 2,000 to 5,000 IUs of vitamin D each day (try using this simple vitamin D dosage calculator to figure out how much you need), as a 12-week weight-loss study found that doing so resulted in lower amounts of fat mass.
Note: There was once a time when certain large companies began to add so much sugar to their yogurt the amounts surpassed those found in sugary breakfast cereal, like Lucky Charms. People were gobbling it up and wondering how it could be so tasty and good for you, when really the image and wholesomeness of yogurt was simply being abused. Read the nutrition label first.
Cut out grains for three weeks. As much as we love carbs, "most grains have a fairly high glycemic index, meaning that after one to two hours, your blood sugar surges," says Dr. Gottfried. "Unfortunately, foods that spike your blood sugar are chemically addictive. They spur inflammation in your body and keep you in a downward spiral of craving that can ultimately lead to a growing waistline." To break the cycle, try scratching grains for less than a month, and pay attention to how your body reacts to the change.

Juice diets do prevent your body from going into a state called ketosis, he says. Ketosis means your body has no carbohydrates to burn for energy, so it has to burn stored fat or whatever else is available, he tells WebMD. "You feel bad, even smell bad. That's what makes you feel like hell during a [water-only] fast. But is that because the toxins are coming out? No! You're going into ketosis. It's known physiology."
