Although they're best known for containing potassium, bananas are also a great source of resistant starch, a type of starch that's important for weight loss. Your body digests resistant starch slowly—helping you feel full for longer—while simultaneously encouraging your liver to switch to fat-burning mode. And no need to wait for them to become completely ripe; bananas actually contain more of this calorie-torching ingredient when they're still a little green.
Like peanuts, avocados contain metabolism-enhancing monounsaturated fats that have been shown to reduce hunger. In fact, a study in Nutrition Journal found that participants who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterwards. What’s more? The trendy toast topping is also loaded with unsaturated fats, which seem to prevent the storage of belly fat, as well as satiating fiber and free-radical-killing antioxidants.
For many people, food is a chore, a challenge, even a source of dread, as they try to overcome poor eating habits. But eating should be a joy and a centerpiece of family life. Many cultures around the world emphasize the enjoyment of food, which includes cooking and eating with others, as an integral component of good health. The latest Dietary Guidelines say that eating healthfully involves “enjoying food and celebrating cultural and personal traditions through food.” According to some research, shared mealtimes, especially during childhood, may help protect against nutrition-related health problems as well as increase prosocial behavior in adulthood.
In children, consuming less than 25 grams of added sugar (100 calories) is recommended per day. Other recommendations include no extra sugars in those under 2 years old and less than one soft drink per week. As of 2017, decreasing total fat is no longer recommended, but instead, the recommendation to lower risk of cardiovascular disease is to increase consumption of monounsaturated fats and polyunsaturated fats, while decreasing consumption of saturated fats.
Diets to promote weight loss are divided into four categories: low-fat, low-carbohydrate, low-calorie, and very low calorie. A meta-analysis of six randomized controlled trials found no difference between the main diet types (low calorie, low carbohydrate, and low fat), with a 2–4 kilogram weight loss in all studies. At two years, all of the diets in the studies that reduced calories caused equal weight loss regardless of whether changes in fat or carbohydrate consumption were emphasized.
Excess sodium, found in many processed foods and restaurant meals, raises blood pressure in some people and can have other adverse effects. The Dietary Guidelines recommend a limit of 2,300 milligrams a day for the general population; people with hypertension or prehypertension can benefit from a further reduction to 1,500 milligrams per day. As you cut back on sodium, eat more potassium-rich foods, which help lower blood pressure. These include citrus fruits, bananas, beans, avocados, some fish, and dairy products.
On top of its 4 grams of belly-filling fiber, a cup of hearty oatmeal delivers as much protein as an egg. In other words, the popular breakfast food is an excellent weight loss tool. In fact, according to a study in the Annals of Nutrition and Metabolism, scientists found that having oatmeal for breakfast resulted in greater fullness, lower hunger ratings, and fewer calories eaten at the next meal compared with a serving of ready-to-eat sugared corn flakes, even though the calorie counts of the two breakfasts were identical. For ways to get more fiber, sprinkle some berries and chia seeds on top of your oatmeal, but be sure to stay away from fattening syrup and sugar.
At least half your grains should be whole grains, such as whole wheat, oats, barley, or brown rice. Whole grains retain the bran and germ and thus all (or nearly all) of the nutrients and fiber of the grain. One sure way of finding whole grains is to look for a product labeled “100% whole wheat” or “100%" of some other whole grain. You can also look for a whole grain listed as the first ingredient, though there still may be lots of refined wheat in the product. Another option is to look for the voluntary “Whole Grain Stamp” from the Whole Grains Council. Or try this tip: Look for less than a 10-to-1 ratio of “total carbohydrates” to “fiber” on the nutrition label.
