Weight loss occurs when you burn
more calories than you consume. You can exercise more to increase your
caloric expenditure, but you will likely have to lower your caloric
intake to achieve your health and fitness goals. Not eating or skipping
meals is not productive, because it slows your metabolism, making it
harder to lose weight. Ideally, you want to remove high-calorie foods
from
your diet and replace them with low-calorie foods. Fruit is a
nutritious low-calorie food group that can be an ideal replacement for
higher-calorie foods.Grapefruit
Grapefruit
is one of the best diet fruits. A medium-sized grapefruit has just 40
calories, and a large grapefruit has just over 60. With a glycemic-index
ranking of 25, grapefruit is one of the lowest-glycemic fruits that you
can eat. There is one additional benefit that makes Dr. Jonny Bowden, a
Los Angeles-based nutrition specialist, recommend grapefruit as one of
the best weight-loss fruits. In spring 2006, researchers at the Scripps
Clinic in San Diego published a study in the "Journal of Medicinal Food"
concluding that grapefruit can improve your insulin resistance and keep
your body from wanting to store fat. Although it is unclear how
grapefruit increases insulin resistance, Scripps Clinic researchers
still recommend it as a diet fruit.
Cantaloupe and Other Melons
Dr.
Bowden recommends cantaloupe because it is a what he calls a
"high-volume" food. A high-volume food has a large amount of water,
fiber and air and a relatively low number of calories. High-volume foods
can benefit you because they satisfy your appetite without costing you
many calories. Melons such as cantaloupe have particularly high amounts
of water. According to Penn State University, water in food remains in
your stomach much longer than water that you just drink. This helps to
curb your appetite and keeps your brain from signaling that you are
hungry and need to eat.
Oranges
The
American Council on Exercise suggests adding oranges to your
weight-loss diet. A medium-sized orange has only 60 calories and is
loaded with vitamins, minerals and anti-oxidants. You can conveniently
take oranges anywhere you go. They are an ideal replacement for
traditional high-calorie snacks such as ice cream, potato chips and
pizza. Dr. Bowden says that oranges are ideal as a diet food, but orange
juice is not. Orange juice has over 20 g of sugar per serving, which is
too much for your diet. In general, solid fruits are better diet foods
than juices because juices have often lost most their fiber content.
Guava
Guava
is one of the best fruits you can eat if you are trying to lose weight.
A medium-sized guava fruit has 8 g of dietary fiber that will help
support your weight loss diet. Fiber not only keeps your appetite under
control, but also keeps your blood sugar stable by slowing the rate that
glucose is absorbed and metabolized. Keeping your blood sugar stable is
vital to achieving your weight-loss goals. When you raise your
blood-sugar levels, your body releases insulin, which promotes fat
storage. You want to prevent insulin release as much as possible if you
are trying to lose weight.
