Obesity: Effect of Physical Exercise

Obesity is a health condition characterized by excess body fat, resulting from a positive energy balance, where caloric intake exceeds energy expenditure over time. This condition is complex and multifactorial, being associated with genetic, environmental, behavioral, and metabolic factors. Depending on the distribution of body fat and body type, obesity can be approached differently. In this article, we will explore the effects of exercise on obesity, how to calculate and interpret body weight, and the importance of considering body type when planning an exercise routine.

Types of Obesity

There are several classifications for obesity, but one of the most common is based on the distribution of body fat:

1. Android Obesity (Apple Type) : Characterized by the accumulation of fat in the abdominal region and trunk, and is more common in men. It is associated with a higher risk of cardiovascular disease, type 2 diabetes and metabolic syndrome.

2. Gynoid Obesity (Pear-Shaped) : In this form of obesity, fat accumulates mainly in the hips, thighs and buttocks, and is more common in women. Although it is less associated with metabolic diseases, it can lead to joint and vascular problems, such as varicose veins.

3. Generalized Obesity : Characterized by the uniform distribution of fat throughout the body. It can result in complications similar to those of android obesity, but with a lower concentration of risk in a specific area.

4. Visceral Obesity : This refers to the accumulation of fat in the internal organs, such as the liver and intestines. It is particularly dangerous as it is strongly associated with an increased risk of metabolic and cardiovascular diseases.

Morphotypes and Obesity

Morphotypes are classifications of different body types, which help to better understand the distribution of fat and muscle mass. The three main morphotypes are:

1. Ectomorph : Characterized by a slim body with little body fat and difficulty gaining weight and muscle mass. People with this body type rarely face obesity problems, but may need to focus on strength training to increase muscle mass.

2. Mesomorph : This body type has a naturally athletic build, making it easy to gain muscle mass and lose fat. Although they can gain weight, mesomorphs tend to respond well to exercise and manage their body weight effectively.

3. Endomorph : Characterized by a greater ease in accumulating fat, especially in the abdominal region. People with this body type are more prone to obesity and may need to focus more on diet and aerobic exercise to maintain a healthy weight.

Endomorphic Morphotype and Obesity

The endomorph body type is the one most predisposed to obesity. People with this body type tend to have a wider bone structure, greater fat accumulation and a slower metabolism. This makes it easier for them to gain weight and have more difficulty losing it.

Challenges of the Endomorph Morphtype

1. Fat Accumulation : Endomorphs tend to accumulate fat quickly, especially in the abdominal area (android obesity), which increases the risk of metabolic diseases.

2. Slow Metabolism : This body type has a lower basal metabolism, which means it burns fewer calories at rest compared to other body types.

3. Difficulty Losing Weight : Due to the combination of a slower metabolism and a greater propensity to accumulate fat, losing weight can be more of a challenge for endomorphs.

Exercise Strategies for Endomorphs

1. Regular Aerobic Exercise : Brisk walking, running, cycling, and swimming are all effective at increasing calorie expenditure and combating fat accumulation. Ideally, endomorphs should perform at least 30 minutes of moderate to intense aerobic exercise five times per week.

2. Strength Training : Weight training is crucial for increasing muscle mass, which in turn helps increase basal metabolism. Exercises such as weight lifting, squats, and resistance training are recommended.

3. High-Intensity Interval Training (HIIT) : HIIT is particularly effective for endomorphs because it combines bursts of intense activity with short periods of rest, resulting in greater fat burning and improved cardiovascular fitness.

4. Diet and Nutrition : In addition to exercise, endomorphs should pay close attention to their diet. Reducing their intake of simple carbohydrates and sugars, and focusing on lean proteins, healthy fats, and complex carbohydrates, can help control weight.

How to Calculate and Interpret Body Weight

One of the most common ways to assess body weight and determine obesity is by calculating the Body Mass Index (BMI). BMI is a measurement that relates weight to height and is used to classify an individual's nutritional status.

BMI calculation

BMI can be calculated using the following formula:

$$\text{IMC} = \frac{\text{Peso (kg)}}$$ {\text{Height (m)}^2}

For example, if a person weighs 85 kg and is 1.70 m tall, the calculation would be:

$$\text{IMC} = \frac{85}{(1,70)^2} = \frac{85}{2,89} = 29,4$$

BMI Interpretation

BMI values ​​are interpreted according to the following World Health Organization (WHO) categories:

• Underweight : BMI less than 18.5
• Normal weight : BMI between 18.5 and 24.9
• Overweight : BMI between 25 and 29.9
• Grade I Obesity : BMI between 30 and 34.9
• Grade II Obesity : BMI between 35 and 39.9
• Grade III Obesity (Morbid Obesity): BMI equal to or greater than 40

While BMI is a useful tool for assessing body weight, it is important to remember that it does not distinguish between muscle mass and fat. Therefore, people with a lot of muscle mass may have a high BMI without this meaning that they are overweight. Furthermore, BMI does not take into account the distribution of body fat, which is an important factor in the risk of diseases associated with obesity.

Benefits of Physical Exercise for Obesity

Physical exercise is a powerful tool in preventing and treating obesity, regardless of type or morphotype. Here are some of the main benefits:

1. Calorie Burning : Regular exercise increases calorie expenditure, helping to create an energy deficit necessary for weight loss. Aerobic and resistance exercises are effective in burning calories and reducing body fat.

2. Increased Metabolism : Exercise can increase your basal metabolic rate, or the amount of calories your body burns at rest. This is especially important in android and visceral obesity, where reducing abdominal fat is crucial.

3. Improved Body Composition : Exercise helps reduce body fat and increase muscle mass. In gynoid obesity, for example, toning the hips and legs can improve body aesthetics and joint health.

4. Reduced Risk of Chronic Diseases : Obesity, especially of the android and visceral type, is strongly associated with chronic diseases such as type 2 diabetes and cardiovascular disease. Regular exercise improves insulin sensitivity, reduces blood pressure and improves cholesterol levels, thus reducing the risk of developing these conditions.

5. Improved Mental Health : Exercise has significant benefits for mental health, including reducing stress, anxiety and depression, which are common in people with obesity. It also improves self-esteem and body image.

Tips for Starting an Exercise Program

If you are starting an exercise program to combat obesity, here are some tips:

• Consult a Health Professional : Before starting any exercise program, consult a doctor or physiotherapist to ensure that the plan is safe and adapted to your type of obesity and body type.

• Set Realistic Goals : Set short- and long-term goals that are achievable and sustainable. Start with low-intensity exercises and gradually increase the intensity and duration as you gain confidence and endurance.

• Combine Exercise with a Healthy Diet : Exercise is most effective when combined with a balanced diet. Consider working with a nutritionist to develop an eating plan that complements your exercise regimen.

• Maintain Consistency : Regularity is key. Choose activities that you enjoy and that you can stick with long-term. Remember that consistency is more important than initial intensity.

• Seek Support : Join training groups or seek support from friends and family. Having company while you exercise can make the experience more enjoyable and motivating.

Conclusion

Exercise plays a vital role in managing obesity, not only by helping you lose weight but also by improving your overall health and quality of life. With a well-structured exercise plan that is tailored to your type of obesity and body type, you can achieve lasting results and live a more active and healthy life.
