In a way, moderate-intensity physical activity is that "magic pill" a lot of people are looking for, because the health benefits go beyond keeping your waistline trim: Not only can it reduce your risk of cancer, stroke, diabetes and heart attacks, but studies have shown that physical activity can significantly improve the moods of patients with major depressive disorders.
The key to losing weight is eating fewer calories than you expend. That creates an energy deficit, so your body taps into other sources of fuel — namely, your fat stores — to make up the difference. You’ll be able to lose weight safely by creating an energy deficit of up to 1,000 calories a day, which will allow you to lose up to two pounds per week.
There are many reasons why you might want to lose weight. If you have been significantly overweight or obese for a long time, then you might have concerns about what the extra weight could be doing to your health. Obesity increases your risk of many health problems, including diabetes, non-alcoholic fatty liver disease, gallbladder disease, and some types of cancer. If you have recently gained a bit of weight, then you might just want to lose some weight to fit back into your old jeans. Whatever your reason for wanting to lose weight, there are some important strategies that you should know about.
Why does this popular plan work? For one thing, it pushes wildly healthy staples to the forefront (think: nuts, vegetables, fruit, olive oil). For another, it's simply delicious, thanks to it's focus on fresh, simply prepared dishes like grilled fish with lemon and whole wheat pita with hummus. Science agrees: One meta-review of 16 studies, found the eating M.O. helped those on it lose an average of 8.5 pounds.
Avoid fad diets. It's never a good idea to trade meals for shakes or to give up a food group in the hope that you'll lose weight — we all need a variety of foods to get the nutrients we need to stay healthy. Avoid diet pills (even the over-the-counter or herbal variety). They can be dangerous to your health; besides, there's no evidence that they help keep weight off over the long term.
As chronic obstructive pulmonary disease (COPD) advances, about 35% of patients experience severe weight loss called pulmonary cachexia, including diminished muscle mass. Around 25% experience moderate to severe weight loss, and most others have some weight loss. Greater weight loss is associated with poorer prognosis. Theories about contributing factors include appetite loss related to reduced activity, additional energy required for breathing, and the difficulty of eating with dyspnea (labored breathing).
Eat More Produce. Eating lots of low-calorie, high-volume fruits and vegetables crowds out other foods that are higher in fat and calories. Move the meat off the center of your plate and pile on the vegetables. Or try starting lunch or dinner with a vegetable salad or bowl of broth-based soup, suggests Barbara Rolls, PhD, author of The Volumetrics Eating Plan. The U.S. government's 2005 Dietary Guidelines suggest that adults get 7-13 cups of produce daily. Ward says that's not really so difficult: "Stock your kitchen with plenty of fruits and vegetables and at every meal and snack, include a few servings," she says. "Your diet will be enriched with vitamins, minerals, phytonutrients, fiber, and if you fill up on super-nutritious produce, you won't be reaching for the cookie jar."
