What are the signs of overweight?

There are a variety of reasons that people are overweight, and there are many signs both physical and mental. Physical signs such as obesity (excess fat on the body) and high blood pressure increase the risk of stroke or heart disease. Overweight or obese individuals may also experience lower quality of life, increased risk of cancer, impaired sleep, increased risk of anxiety, and decreased ability to exercise. Psychological signs include increased feelings of tiredness or anxiety, a desire to sleep more, and a preference to eat less than what they should eat. A weight loss program can help improve all these signs.

Anonymous Patient Answer

Can overweight be cured?

The weight loss from the combination of diet and exercise can be maintained 6 months post-intervention but the BMI continues to rise for several years. Only approximately 11 subjects can be considered to have been cured of their excess weight; the remainder would be still underweight. Overall, although diet and exercise can substantially alter the shape of the body, it is difficult to be certain whether it can be completely cleared.

What is overweight?

In most countries in Europe, as in the USA, overweight is much more common than obesity. In the developed world, overweight represents the leading risk factor for chronic disease. However, a high proportion of the population in Europe and South America was classified as obese while in the USA, this proportion is about one third lower.

Anonymous Patient Answer

What causes overweight?

People overestimate the impact of diet and lifestyle in the development of overweight. This finding is consistent with the observation that behavioral factors are more effective in leading to an increase in weight than a decrease in physical activity. People's overconfidence of their ability to reduce weight is a barrier for adopting a more healthy lifestyle. In the context of nutrition, overweight is a modifiable and potentially treatable risk factor for hypertension, ischemic heart disease, and cancer.

What are common treatments for overweight?

In a European country, the overall use of medications is similar to the rates reported in the literature for the United States. However, overweight patients were more likely to receive non-standard treatment in comparison with the US population, particularly weight loss-related treatment such as surgery or surgery-related medication.

How many people get overweight a year in the United States?

About 6.4 million Americans have high blood pressure, and about 18% of the US population have blood pressure that is high enough to make it a disease. These data, taken together, indicate that more than 7.2 million Americans are at risk of developing hypertension. This implies that over half (53%) of the adult population and 40% of high school students in the U.S. have high blood pressure.

What is blueberry plus exercise (bb-ex)?

Recent findings demonstrated an improvement in glucose homeostasis and a better lipid profile when the meal after exercise is a high-fat, low-carbohydrate blueberry-flavored beverage relative to exercise alone. It is proposed that the beverage may contribute to the improvement of the lipid profile without negatively impacting exercise-induced gains in insulin sensitivity, body weight, lean body mass and physical endurance.

Anonymous Patient Answer

What does blueberry plus exercise (bb-ex) usually treat?

The present study suggests that a short term intake regimen of two berries may not be sufficient for increasing the aerobic capacity of overweight-to-morbidly obese individuals. However, if the berry intake regimen in the study was feasible, it might have significant benefit in the improvement of some metabolic alterations associated with the overweight-to-morbidly obese state. Further studies are needed to elucidate the most efficient berry intake regimen for improving both physical and metabolic fitness in overweight-to-morbidly obese individuals.

Anonymous Patient Answer

Have there been any new discoveries for treating overweight?

There have always been ideas and new treatments for overweight. There is currently work to discover new ways to treat overweight and to decrease risk factors and improve the outcomes. We will see if we can prevent obesity. This can be done better by decreasing stress, improving our overall diets by changing food choices and having an overall healthier lifestyle.

Anonymous Patient Answer

What is the primary cause of overweight?

The primary cause of overweight is, undoubtedly, genetic makeup, meaning family history, but it is estimated that 75-80 percent of weight gain in women is related to lifestyle factors. There appears to be a strong association between excessive eating and weight gain; if any amount of food can gain a person more than 5 kg, they will eventually gain more than 5 kg. Obesity is associated with more unhealthy lifestyles in women.

What is the latest research for overweight?

There is a lack of research regarding the treatment and management of overweight. We need to have knowledge about what treatments and management are most effective for overweight patients. The information should also be provided in ways understandable to patients.
