THe Reality of Obesity today ! weight loss help reducing obesity

---

Obesity is defined as having a body mass index (BMI) of 30 or higher. It is a major public health problem, as it is associated with a number of chronic diseases, including type 2 diabetes, heart disease, stroke, and certain cancers.

There is a strong correlation between obesity and chronic disease. A meta-analysis is a study that combines the results of multiple studies to get a more accurate picture of the relationship between two variables. A meta-analysis of prospective cohort studies found that obesity was associated with an increased risk of type 2 diabetes, heart disease, and certain cancers (Bray et al., 2004).

Another meta-analysis found that obesity was associated with a significantly increased risk of developing type 2 diabetes, with the risk increasing as BMI increased (BMI ≥30) (Chen et al., 2014).

The relationship between obesity and heart disease is complex, but there is evidence to suggest that obesity is a major risk factor for heart disease. A meta-analysis of observational studies found that obesity was associated with a significantly increased risk of heart disease (Ong et al., 2014).

Obesity is also associated with an increased risk of certain cancers, including breast, colon, and kidney cancer. A meta-analysis of prospective cohort studies found that obesity was associated with an increased risk of breast, colon, and kidney cancer (Bray et al., 2004).

Overall, the evidence suggests that there is a strong correlation between obesity and chronic disease. Reducing obesity can help to reduce the risk of developing chronic diseases such as type 2 diabetes, heart disease, and certain cancers.

Obesity rates in North America are high. According to data from the World Health Organization, the obesity rate in the United States was 39.8% in 2016, and the obesity rate in Canada was 28.3% in 2014. These rates have been rising over time, and obesity is a major public health concern in both countries. It can lead to a range of health problems, including diabetes, heart disease, and some types of cancer.

why does obesity keep rising ?

Obesity rates have been rising in many countries over the past few decades. There are many factors that have contributed to this trend, including:

1. Changes in diet: A diet that is high in processed foods and added sugars can lead to weight gain and obesity.
2. Lack of physical activity: A sedentary lifestyle, characterized by limited or no regular physical activity, can also contribute to weight gain and obesity.
3. Genetics: Obesity tends to run in families, and studies have suggested that there may be genetic factors that make some people more susceptible to gaining weight.
4. Socioeconomic factors: Some research suggests that people who are living in poverty or in disadvantaged communities may be more likely to be overweight or obese due to lack of access to healthy food options and safe places to exercise, social norms and other more complex factors.
5. Environmental factors: Today, many of our built environments make it easy to engage in sedentary behavior and eat high-caloric foods.
6. Societal and cultural factors : societal pressure to be thin and ideal body shape portrayals can lead to body dissatisfaction and eating disorders, leading to maladaptive eating behaviors.

All of these factors interact and contribute to the rising rates of obesity, and addressing this problem will likely require a multifaceted approach, including changes to diet and physical activity, as well as addressing larger environmental, social and cultural factors.

what foods should people avoid who are suffering from obesity?

If you are obese, it's important to focus on eating nutrient-dense, low-calorie foods that will help you lose weight in a healthy way. Some specific foods to avoid if you're trying to lose weight include:

1. Processed foods: Many processed foods are high in calories, added sugars, and unhealthy fats.
2. High-calorie drinks: Sugary drinks such as soda, juice, and sweetened coffee and tea can add a lot of empty calories to your diet.
3. Fast food: Fast food is often high in calories, unhealthy fats, and added sugars.
4. Sweets and desserts: Cookies, cakes, and other sweet treats are high in calories and added sugars and should be avoided or consumed in moderation.
5. Fried foods: Fried foods are often high in calories and unhealthy fats, which can contribute to weight gain.
6. Foods high in saturated and Trans fats: such as butter, cheese, cream, and fatty meats, should be avoided or consumed in moderation.

Instead, it's a good idea to focus on eating whole, unprocessed foods such as fruits and vegetables, lean proteins, and whole grains. Try to eat smaller, more frequent meals throughout the day, and be mindful of portion sizes when eating. And drinking water and other low-calorie beverages is also important. It's important to note that everyone's nutritional needs and caloric requirements are different, Consulting with a nutritionist or a dietitian can help you create a personalized eating plan that will meet your needs.

How does Strength training help with Obesity?

Obesity is a major public health concern, affecting millions of people worldwide. It is defined as an excessive accumulation of body fat, which can lead to a range of health problems, including diabetes, heart disease, and some types of cancer (WHO, 2018). One of the most effective ways to combat obesity is through regular physical activity, in combination with a healthy diet (CDC, 2020).

Strength training, also known as resistance training, is a type of exercise that involves using weights or other resistance to work against gravity. This type of exercise is known to increase muscle mass, which in turn can lead to an increased metabolism (Katz, et al. 2018). An increased metabolism means that the body burns more calories at rest, leading to weight loss and decreased body fat (Katz, et al. 2018). Additionally, strength training has been shown to improve insulin sensitivity, which can be beneficial for individuals with type 2 diabetes (Katz, et al. 2018).

Strength training can also improve body composition by decreasing body fat and increasing muscle mass (CDC, 2020). This is particularly important for individuals who are obese, as a higher muscle mass can increase the number of calories burned at rest, making it easier to maintain weight loss (CDC, 2020).

In addition to its physical benefits, strength training can also have psychological benefits for individuals who are obese. This type of exercise can improve self-esteem, confidence, and body image, which can be particularly beneficial for individuals who may have experienced discrimination or stigma due to their weight (Katz, et al. 2018).

Overall, strength training is an important component of an exercise program for individuals who are obese. Its benefits include increased muscle mass, improved metabolism, and decreased body fat. In combination with a healthy diet, regular strength training can help to combat obesity and its associated health risks.
