Electrolytes play a major role in keeping us alive since they provide the electrical current that allows our muscles, particularly the heart, to contract at the right speed. When there is a sudden decrease of food intake, there is also a sudden decrease in the electrolytes that our bodies are used to getting, particularly potassium and magnesium. If the body can’t handle the deficit, this can lead to impaired cardiovascular function and irregularities such as heart arrhythmias.
Catechins are also credited for green tea’s cancer-fighting potential. These antioxidants have the ability to block the action of molecules called free radicals, which can cause changes in healthy cells that sometimes lead to cancer. But there’s no solid proof yet that the catechins in green tea help to prevent cancer in humans, despite some promising studies in test tubes and animals.
A few months after her death, in January 2009, some family members and I decided to join Weight Watchers. Even though I knew I needed to get healthy, I was reluctant to go. But after starting to get into it, I became so much more aware of everything I was putting in my body. Although the program helped me at first, I decided that I wanted to start making changes to my diet and exercise on my own. I needed to change my lifestyle, and I knew that keeping track of points for the rest of my life wasn't going to work for me. 

It’s true that green tea can raise your metabolic rate, so you burn more calories, says David Nieman, Dr.PH., director of the human performance laboratory at Appalachian State University in Boone, N.C. Nieman, who has studied green tea extensively, says this effect is probably due to a combination of its caffeine and catechins—antioxidants that are plentiful in green tea and present in smaller amounts in some fruits, dark chocolate, and red wine.
These sweet, juicy summer berries are tasty both fresh and dried in trail mix or in a salad, says Lisa Dorfman, a registered dietitian and author of The Reunion Diet. “At just 43 calories per 3.5 oz serving, they contain 61 percent of the RDA for vitamin C, and they’re also chock full of potassium, fiber, and resveratrol, a phytonutrient shown to protect the heart.”
Your daily cup of joe may do more than just help you roll out of bed each morning. It stimulates the brain and nervous system, and contains antioxidants that may help improve glucose metabolism — which not only helps suppress the appetite, but also lowers the risk of Type 2 diabetes. Caffeinated coffee may also stimulate thermogenesis, and the body’s ability to burn more fat stores, improving performance in endurance exercises like running and biking.
Trying to lose weight is a lot like cleaning out the basement: It’s overwhelming and near impossible to know where to start—even when you don’t have a ton of weight to lose. But getting the body you’ve always wanted doesn’t have to be a source of stress. If the scale won’t budge and you’re looking to shed the last 10 pounds, there are plenty of ways to reach your goal.

The math behind the body weight color coding, something called Body Mass Index (BMI), is applicable and useful for about 95% of the population. It is not useful for highly fit people (who won't be using this calculator anyway). It is also not useful for very tall people. Use the color coding as a guideline for evaluating your body weight. Don't use it as a medical diagnosis.
A study in the journal Metabolism found that eating half a grapefruit before meals may help reduce visceral fat and lower cholesterol levels. Participants in the 6-week study who ate a Rio Red grapefruit fifteen minutes before each meal saw their waists shrink by up to an inch, and LDL levels drop by 18 points. Though researchers don’t exactly know what makes grapefruit so good at burning fat, they attribute the effects to a combination of phytochemicals and vitamin C found in the tart treat.
“Stepping on the scale frequently makes you aware of small changes and helps you quickly react to those changes. The National Weight Control Registry, a large group of people who have successfully lost at least 30 pounds and kept it off for 5 years, found that successful ‘losers’ weigh themselves often and make adjustments accordingly. When you begin to understand that sodium, carb intake, hormones and alcohol intake can impact weight and that it isn’t possible to gain 2 pounds of fat overnight, you will begin to better understand your body. The key is to pay attention to overall trends; don’t obsess over day-to-day numbers! — Jennifer McDaniel, MS, RDN, CSSD, LD, food and nutrition expert

To reap the other benefits of weight loss, however, you have to stick with it – something that's a lot harder for average Joes than for TV stars-in-the-making.

Preheat oven to 400°. Slice 1 small potato into fry shapes; toss with 1 teaspoon olive oil and 1 teaspoon chili powder. Roast on baking sheet until golden (about 30 minutes).

Although white potatoes offer some potassium and fiber, sweet potatoes reign supreme in the nutrition department, meaning you should consider adding sweet potatoes to your diet. A large sweet potato contains around 4 grams of satiety-boosting protein, 25 percent of the day’s belly-filling fiber, and 11 times the recommended daily intake of vitamin A. What’s more? It’s less than 200 calories.
