The secret to Katy Perry's "California Gurl" body? Mushrooms. With the M-Plan diet, Perry eats a mushroom-packed lunch or dinner every day for 14 days, then watches the pounds slip off. Great for removing unwanted bulk from problem areas like the stomach and thighs, the program still allows the dieter to retain her womanly shape—the mushroom meal plan won't effect the bust.
Eat more protein. Sarcopenia, or loss of muscle due to age, has been seen as inevitable, but a great deal of its severity is dictated by diet and exercise. Protein can help! One study found that men and women between ages 70 and 79 who ate the most protein lost 40 percent less lean mass than those who ate the least protein. Muscle burns more calories, increases your insulin sensitivity, and keeps your testosterone production higher so that you can help stave off age-related health conditions, such as metabolic syndrome, diabetes, and loss of libido.
“Most 40-year-olds can remember the fat-free craze of the ’90s, when Snackwells was king,” says Shapiro. “Well, those days are over.” She advises that you leave the fat-free fake foods behind and enjoy healthy fats that add flavor to your meals and help you fill up with less. “Coconut oil, avocado, nuts, seeds, salmon are rich in vitamins and minerals that will keep you young and fill you up on smaller portions, and therefore fewer calories.” She says.
