Today, we will be talking about diet and weight loss. Exercise is important if you want to get in shape. However, experts say that exercise alone is not enough if your goal is to lose weight.
It’s that time of year again! The warm weather has returned to the northern hemisphere. Summer is a time when people of all ages want to get their swimwear out and go to the nearest swimming pool or beach. But first, there’s that troublesome little thing called winter weight gain.
Many of us gain weight due to inactivity during the winter months. Some people will go to great lengths to lose that extra weight before they go to the beach. The weight loss industry is full of ideas about how to lose weight. One such idea is the sleeping beauty diet, where you supposedly lose weight by sleeping. The theory is that you cannot eat if you are sleeping. Then there is the tapeworm diet. The tapeworm is said to help people lose weight by eating the food stored in their stomach. However, you first have to be willing to swallow the little creature. This may be more trouble than many people want. Strange new diets, treatments and exercise programmes appear on the market every day. Each one promises to help people lose weight and achieve a beach-ready body. The weight loss industry generates billions of dollars each year, and this figure is growing. One research company estimates that the weight loss industry will be worth around $670 billion worldwide by 2015.
According to Markets and Markets, the business is made up of three main areas. These are: weight loss services; physical fitness and surgical equipment; and diets, including food and drink products. There is an endless supply of ideas about how to lose weight. These include low-carbohydrate diets, low-fat diets, calorie-restricted diets and free-for-all diets. Not to mention the thousands of different diet pills and programmes. So where does one begin? Which is best? Experts agree that there is no single diet plan that works best for everyone. However, many experts agree on one thing: to lose weight, you must use or burn off more calories than you consume. When you consume more calories than your body needs, it stores the excess energy as fat. Calories are a measure of the energy in food. One pound of fat is equivalent to 453 grams, or approximately 3,500 calories. To lose that fat in a week, you have to burn off at least that amount of calories, or consume that many fewer calories. The best approach is to combine both strategies. Eat fewer calories and increase your physical activity to burn off more.
According to America’s National Institutes of Health, eating plans containing 1,000–1,200 calories per day help most women to lose weight safely. It states that eating plans containing 1,200–1,600 calories per day are suitable for men seeking to lose weight. These calorie levels may also be suitable for women who weigh 75 kilograms or more, or who exercise frequently.
For years, it was said that eating a low-fat diet was the best way to lose weight. This is a diet in which less than 30 per cent of a person’s daily calorie intake comes from fat. Dean Ornish developed one of the most popular low-fat diets following years of research into ways to control heart disease. He first published his dietary ideas in the medical journal The Lancet in 1990. The Ornish diet plan gained further popularity in 1993 with the publication of his book Eat More, Weigh Less. Dr Ornish studied the effects of carbohydrates, which are one of the body’s most important sources of energy. He concluded that carbohydrates were not responsible for making people fat. Instead, he concluded that it is fat that makes people fat. He noted that a baked potato is not high in fat, but becomes fatty when people add sour cream and butter. The diet plan limits daily calories from fat to less than 10 per cent, with little to no saturated fat or cholesterol. He also recommends that people obtain 70–75% of their calories from complex carbohydrates and 15–20% from proteins.
Like other low-fat diets, the Ornish plan recommends eating a diet high in whole grains, fruits, vegetables, beans, and other legumes. However, the plan advises people to avoid all meat and meat products, as well as oils, nuts and seeds. It does not limit the number of calories consumed. However, eating the foods recommended by the diet would reduce calorie intake. The Ornish diet has proved effective for many people. However, critics say it allows dieters to consume too many carbohydrates while restricting calories from fat. They also claim that the required changes to eating habits may be too extreme for many people to follow. Unlike the Ornish diet, low-carbohydrate diets restrict foods that are high in carbohydrates. They advise people to avoid foods such as white flour, pasta, rice, potatoes and sugary foods. Instead, they recommend eating foods that are high in protein and fat.
These include meat, fish, chicken, eggs, cheese and nuts. One of the most popular of these diets is the Atkins diet. It recommends eating fewer than 20 grams of carbohydrates per day. This amount is then gradually increased to between 40 and 100 grams per day to maintain weight loss. Both weight loss plans have been carefully studied over the years. However, neither has emerged as a clear winner. In 2008, however, a study in the New England Journal of Medicine found that low-carbohydrate diets were the most effective for weight loss. This study was led by researchers at Brigham and Women’s Hospital in Boston and Ben Gurion University in Israel. The researchers studied over 300 obese patients who followed one of three dietary plans. These were a low-fat diet, a low-carb diet, and a Mediterranean diet consisting of fruit, vegetables, lean proteins, olive oil, and nuts. A similar study, published a year later, examined over 800 dieters.
The study found that low-fat and high-fat diets were equally successful in providing and maintaining weight loss over two years. The researchers concluded that the most important thing about any diet is that people stick to it. You must also burn more calories than you consume, regardless of what you eat. Some people are unable to lose weight through diet and exercise, no matter how hard they try. Others are simply unwilling to put in the effort. Many of these people opt for surgery to help them reach their weight loss goals. One type of weight loss surgery involves reducing the size of the stomach. This is achieved by dividing the stomach into two sections, one of which is very small. Those who have undergone this procedure are forced to eat smaller amounts of food because the upper stomach fills up much faster. Research suggests that most people lose around half of their excess weight in the first year after surgery. However, many people regain the weight within three to five years. Similar results have been reported for another popular weight loss surgery.
Liposuction has been used to improve body appearance since the 1970s. It reshapes the body by removing fat from specific areas. The most common areas are the stomach, waist, hips, thighs, neck and arms. According to the International Society of Aesthetic Plastic Surgery, liposuction is the most popular form of cosmetic surgery worldwide. However, researchers at the University of Colorado School of Medicine recently found that the effects of the surgery may not be long-lasting. They found that people who have liposuction usually experience weight gain within one year of the procedure. The fat that returns tends to appear in a different area of the body, most notably the shoulders, arms and upper abdomen. The researchers say this is one more reason to try to prevent obesity before it develops.
