As a rough rule of thumb, 1 pound of fat contains about 3,500 calories, so one could lose a pound a week by reducing daily caloric intake by about 500 calories a day.
To determine the daily calorie requirements for specific individuals, multiply the number of pounds of ideal weight by 12 - 15 calories.
The number of calories per pound depends on gender, age, and activity levels. For instance a 50-year-old moderately active woman who wants to maintain a weight of 135 pounds and is mildly active might need only 12 calories per pound (1,620 calories a day).
A 25-year old female athlete who wants to maintain the same weight might need 25 calories per pound (2,025 calories a day).
Fat intake should be no more than 30% of total calories. Most fats should be in the form of monounsaturated fats (such as olive oil). Avoid saturated fats (found in animal products). Oct 8

Research in the Linus Pauling Institute has found a second mechanism by which foods rich in sulforaphane, such as broccoli, can help prevent cancer. (Photo courtesy U.S. Department of Agriculture) Researchers in the Linus Pauling Institute at Oregon State University have discovered yet another reason why the "sulforaphane" compound in broccoli and other cruciferous vegetables is so good for you – it provides not just one, but two ways to prevent cancer through the complex mechanism of epigenetics. Epigenetics, an increasing focus of research around the world, refers not just to our genetic code, but also to the way that diet, toxins and other forces can change which genes get activated, or "expressed."
Black Cumin Oil: ‘One of the Most Important Oils for Your Health’ Popular in Middle Eastern cooking, black cumin (Nigella sativa) are amazingly healthful seeds native to south and southwest Asia. The history of black cumin as a healer is undeniable, with popularity of the seeds slowly returning. Continue Reading Do Grains Deserve a Spot in any Food Pyramid?
When you're staring down the barrel of a new diet, your portions are one of the most difficult things to measure and keep track of. Your kitchen scale may be great in the comfort of your home, but it's not practical to carry with you all day. Instead, just get to know the rough estimates with your hand. If the idea looks familiar, that may be because earlier this month Melanie walked through the basics of this idea, highlighting its usefulness for cooks.
One of the hardest parts of dieting is figuring out what you can actually eat. Swole.me is an app that figures out your meals for you. You simply tell it your calorie goal, what meals you want to eat, and what foods you want to include in those meals and it'll generate a plan in seconds. All you really need to enter is the number of meals you want to eat and your calorie goal.
A new study by Oregon researchers suggests that all those holiday treats, backed up by year-round junk food, might be going to your head, and not in a good way. Research by scientists at Oregon State University and Oregon Health & Science University has found that older people whose diets are big on unhealthy, fatty foods do worse on mental acuity tests and have more brain shrinkage than those with healthy diets. Older people who eat lots of fruits and vegetables and the healthy oils found in fish were sharper and had less brain shrinkage. The study is getting attention because it’s the first to measure the effect of diet on brain size and function by directly measuring nutrient levels in the blood and by imaging brains using an MRI.
Overeating may cause brain aging while eating less turns on a molecule that helps the brain stay young. A team of Italian researchers at the Catholic University of Sacred Heart in Rome have discovered that this molecule, called CREB1, is triggered by " caloric restriction " (low caloric diet) in the brain of mice. They found that CREB1 activates many genes linked to longevity and to the proper functioning of the brain. This work was led by Giovambattista Pani, researcher at the Institute of General Pathology, Faculty of Medicine at the Catholic University of Sacred Heart in Rome, directed by Professor Achille Cittadini, in collaboration with Professor Claudio Grassi of the Institute of Human Physiology . The research appears this week in the Proceedings of the National Academy of Sciences ( PNAS ). "Our hope is to find a way to activate CREB1, for example through new drugs , so to keep the brain young without the need of a strict diet ," Dr Pani said.
(Newser) – Scientists have long known that calorie-restricted diets— as in 30% fewer calories than normal —are a key to living longer and keeping your brain healthier. But now, for the first time, they think they know why: Apparently extreme calorie restriction triggers a brain protein, CREB1, that unlocks good genes and brain function, reports the AFP . "CREB1 is known to regulate important brain functions [such] as memory, learning, and anxiety control, and its activity is reduced or physiologically compromised by aging," wrote the researchers.

Food allergy is an abnormal response to a food triggered by your body's immune system. In adults, the foods that most often trigger allergic reactions include fish, shellfish, peanuts, and tree nuts, such as walnuts. Problem foods for children can include eggs, milk, peanuts, tree nuts, soy, and wheat.
Food Allergy Myths Medical Author: Melissa Conrad Stöppler, MD Medical Editor: Jay W. Marks, MD Food allergies are often misunderstood, even though societal recognition of, and education about, the condition is increasing. See if you have heard ? or believed ?
A drink with as little as one gram of lemon grass contains enough citral to prompt cancer cells to commit suicide in the test tube according to new Israeli research. At first, Benny Zabidov, an Israeli agriculturalist who grows greenhouses full of lush spices on a pastoral farm in Kfar Yedidya in the Sharon region, couldn’t understand why so many cancer patients from around the country were showing up on his doorstep asking for fresh lemon grass. It turned out that their doctors had sent them. “They had been told to drink eight glasses of hot water with fresh lemon grass steeped in it on the days that they went for their radiation and chemotherapy treatments,” Zabidov told ISRAEL21c.
No matter how you slice it, watermelon has a lot going for it –– sweet, low calorie, high fiber, nutrient rich –– and now, there’s more. Evidence from a pilot study led by food scientists at The Florida State University suggests that watermelon can be an effective natural weapon against prehypertension, a precursor to cardiovascular disease. It is the first investigation of its kind in humans. FSU Assistant Professor Arturo Figueroa and Professor Bahram H. Arjmandi found that when six grams of the amino acids L-citrulline/L-arginine from watermelon extract were administered daily for six weeks, there was improved arterial function and consequently lowered aortic blood pressure in all nine of their prehypertensive subjects (four men and five postmenopausal women, ages 51-57). “We are the first to document improved aortic hemodynamics in prehypertensive but otherwise healthy middle-aged men and women receiving therapeutic doses of watermelon,” Figueroa said.
Two out of three people in America today are either overweight or obese. That means every time you sit down in an airplane or a packed movie theater, more likely than not you’re going to wind up as the lean center of a fat sandwich. But as you look right and left and see nothing but heft, you can’t help but think, What happened?
