Weight Management: All you Need to Know about Weight Management in 2023

What is Weight Management?

Weight management involves reaching and maintaining a healthy body weight throughout different stages of life. It is a crucial aspect of your overall health. Being underweight, overweight, or obese can increase your risk for chronic health conditions, such as type 2 diabetes, hypertension, heart disease, stroke, certain cancers, and more. It can also lead to joint problems, sleep apnea, and other health problems that can negatively impact your quality of life. Additionally, it can affect your mental and emotional health, leading to depression, anxiety, and poor body image.

Generally, weight management strategies combine diet, physical activity, stress management, mental health, sleep, and other lifestyle interventions. You can significantly reduce your risk of developing these chronic diseases by maintaining a healthy weight. It can also improve your energy levels, sleep, mood, and mobility. Achieving weight loss goals and improving health can increase self-confidence and self-esteem. Thus, weight management can help you feel better physically and mentally, enhancing your overall quality of life.

However, when talking about healthy weight, there is no one-size-fits-all solution. The ideal weight range for every individual is unique. It depends on several factors such as age, sex, genetics, bone structure, existing medical history, lifestyle habits, diet, height, and weight as a young adult. Various weight assessment tools such as BMI, waist circumference, body fat percentage, and weight-to-height ratio are available. But it is best to talk to your healthcare provider to determine your ideal weight goals. They will consider your unique health history and characteristics to provide personalized recommendations for a healthy weight range.

What are the Different Classifications of Weight?

Weight can be classified into different categories based on the body mass index (BMI) value. It is a measure of body fat based on height and weight. The most common categories used are:

• Underweight: A person with a BMI less than 18.5 is considered underweight.
• Normal Weight: A person with a BMI between 18.5 and 24.9 is considered normal or healthy.
• Overweight: A person with a BMI between 25 and 29.9 is considered overweight.
• Obese: A person with a BMI of 30 or higher is considered obese.

What are Unexplained Weight Gain and Weight Loss?

Unexplained weight gain refers to a sudden increase in body weight without any obvious or intentional cause, such as overeating or decreased physical activity. It can signify an underlying medical condition, hormonal imbalances, or medication side effects. Apart from the apparent symptom of rapid weight gain, you may experience bloating, abdominal pain, fatigue, lethargy, irregular menstrual periods, changes in libido, swelling, changes in appetite or thirst, skin changes, joint pain or stiffness, increased sensitivity to cold temperatures, and mood changes.

Unexplained weight loss is a significant decrease in body weight that occurs without intentional efforts to lose weight or without an apparent cause. Generally, a weight loss of 5% or more of body weight over six months or less is considered unintentional. It can be concerning as it may be a symptom of severe underlying conditions. Common signs of unexplained weight loss include loss of appetite, feeling full quickly even after eating small amounts of food, fatigue, and weakness. In some cases, there may be additional symptoms such as diarrhea or constipation, nausea, vomiting, stomach pain, increased thirst, frequent urination, mood changes, fever, night sweats, and unexplained pain. Talking to a doctor if you have unexplained weight gain or loss is essential.

What are the Different Ways to Assess Weight?

There are several methods to assess your weight and determine if you fall in the healthy weight range. Many of these are at-home assessments that you can perform using simple tools and online calculators. If you are underweight, overweight, or obese, discussing it with your healthcare provider rather than making sudden drastic changes is best. Here are some ways to assess your weight:

1. Weighing Scale Measurement

Weighing scale measurement determines an individual's total weight by measuring the gravitational force that the person's body exerts on the scale. It is a simple and commonly used weight assessment method, but it does not provide information on body composition or other factors that may be important for overall health. Furthermore, if you are tracking your weight over time, you must do it simultaneously and under the same conditions every time for the most accurate results. It is best to check your weight early in the morning on an empty stomach and bladder.

2. Body Mass Index (BMI)

Body mass index (BMI) measures an individual's weight relative to height. To calculate your BMI, you need to divide your weight in kilograms by the square of your height in meters (kg/m²). BMI is commonly used as a screening tool to determine whether an individual is underweight, healthy, overweight, or obese.

Body Mass Index = weight (kg) / [height (m)]2

BMI is not the most accurate measure of body fatness, as it does not consider factors such as muscle mass, bone density, or body composition. As a result, it may not be accurate for specific populations, such as athletes, elderly individuals, or pregnant women. However, for most adults, BMI provides a reliable estimate of body fatness and helps assess overall health and disease risk.

• If your BMI is less than 18.5, you fall in the underweight range.
• If your BMI is between 18.5 to 24.9, you fall in the healthy weight range.
• If your BMI is between 25.0 to 29.9, you fall in the overweight range.
• If your BMI is 30.0 or higher, you fall in the obese range.

3. Waist Circumference

Waist circumference measurement determines the amount of abdominal fat an individual has. To correctly measure your waist circumference, you need to wrap a measuring tape around the waist at the level of the belly button. Your waist circumference is a crucial indicator of abdominal obesity, associated with a higher risk of hypertension, heart disease, type 2 diabetes, and other health problems. You have a high waist circumference if:

• You are a man with a waist circumference of over 40 inches (102 cm).
• You are a non-pregnant woman with a waist circumference of over 35 inches (88 cm).

However, waist circumference measurements are just a screening tool and should be used with other measurements, such as BMI, to assess overall health.

4. Waist-to-hip Ratio

Waist-to-hip ratio measurement determines the distribution of body fat in an individual. You can calculate it by dividing the waist circumference (measured at the narrowest point) by the hip circumference (measured at the widest point) using any units of measurement. The waist-to-hip ratio is an essential indicator of overall body fat distribution and is associated with health risks, including heart disease and diabetes. You have a high waist-to-hip ratio if:

• You are a man with a waist-to-hip ratio of 0.90 and above
• You are a woman with a waist-to-hip ratio of 0.85 and above

Like other body composition measurements, the waist-to-hip ratio should be used in conjunction with other indicators of health, such as BMI and waist circumference, to get a complete picture of an individual's overall health risk.

5. Weight-to-height Ratio

The waist-to-height ratio indicates if an individual has excess abdominal body fat. To calculate it, you only need a long piece of string. First, measure your height using the string and then fold that length of string into half. Wrap the folded string around your waist and check if it fits entirely. If it does not, you have a high weight-to-height ratio. It indicates an increased risk of obesity-related health conditions such as type 2 diabetes and heart disease.

6. Bioelectrical Impedance Analysis (BIA) or Smart Scales

Bioelectrical impedance analysis (BIA) measures body composition metrics, including body fat, muscle mass, and body water percentage. It involves using a smart scale that resembles a regular weighing scale. When you stand on the scale, low-level electrical impulses travel through your body and measure the resistance to the flow of that current. Fat has more excellent resistance than water or muscles and hence:

• If you have more body fat than lean mass, there will be greater impedance (resistance), and the rate of the electric currents will be slower.
• If you have more lean mass than body fat, there will be lesser impedance (resistance), and the rate of the electric currents will be faster.

However, the accuracy of BIA results can be influenced by factors such as body weight, hydration level, recent exercise, and recent food or fluid intake.  

7. Body Circumference Measurements

Circumference measurement is a technique used to assess body fat by measuring the circumference of various body parts, such as the waist, hip, thigh, and upper arm, with a measuring tape. You can enter the measurements into a formula to understand your body fat percentage. The type of measurements and the equation varies for both genders.

• If you are a man, you will measure your neck, waist, and height.

After that, use the following formula to calculate your body fat percentage.

Body fat percentage for men = 86.010 x log10 (waist – neck) – 70.041 x log10 (height) + 36.76

• If you are a woman, you will measure your neck, waist, hips, and height.

After that, use the following formula to calculate your body fat percentage.

Body fat percentage for women = 163.205 x log10 (waist + hip – neck) – 97.684 x log10 (height) – 78.387

What Factors Affect Weight and Health?

Weight gain and weight loss can occur due to various underlying factors, such as:

Family History and Genetics

Family history and genes can significantly impact an individual's weight. Some people may have a genetic predisposition to store fatter or have a slower metabolism, making it more challenging to maintain a healthy weight. Genetic variations may also affect how the body responds to certain foods or influence hunger and satiety cues, impacting food intake and weight regulation. Similarly, family history can also play a role in weight and obesity. Parents and their children may share similar eating habits, physical activity levels, and other lifestyle factors that can influence weight. Hence, children of overweight or obese parents are more likely to fall in the same weight range.

Age

It is common for individuals to experience changes in body weight and body composition as they age. Ageing leads to muscle loss, bone loss, fat gain, slower metabolism, hormonal changes, and lifestyle changes. Additionally, you may develop certain chronic health conditions and take medications that influence your weight.

Physical Activity

A sedentary lifestyle, which involves limited physical activity and prolonged periods of sitting or lying down, can influence your weight and overall health. As a result, you may experience muscle loss, slower metabolism, greater appetite, and decreased calorie burn. You may become overweight or obese and be at a higher risk of developing related chronic diseases.

Diet and Eating Habits

Your caloric and nutrient intake and eating habits are crucial factors in weight gain or loss. Eating more calories than burning them will lead to weight gain while eating fewer calories than burning them will lead to weight loss. Similarly, the kind of calories you intake influences your weight. A diet high in nutrient-dense foods, such as fruits, vegetables, lean proteins, and whole grains, can promote weight loss and overall health. But regular consumption of highly processed, sugary, and fatty foods can contribute to weight gain and poor health outcomes. Skipping meals, eating quickly, or overeating under stress are all habits that are detrimental to maintaining a healthy weight.

Sleep

Getting adequate quality sleep is crucial to maintaining a healthy weight. A lack of it can lead to imbalances in the hunger hormones, including leptin and ghrelin, which can lead to increased appetite and overeating. Your energy levels will also be low, causing you to make poorer food choices and eat high-calorie foods to up your energy levels. You may also not feel motivated to engage in physical activity due to fatigue. Lack of sleep also impacts your insulin sensitivity and how the body metabolizes fat, contributing to weight gain.

Environment

Your environment plays a massive role in influencing your health preferences. Regular exposure to advertising and marketing for unhealthy foods, such as fast food, sugary drinks, and snacks, can compel you towards them. Furthermore, living in an area with limited access to healthy foods can make it challenging to maintain a healthy diet. The lack of physical activity options, such as parks, sidewalks, and recreational facilities, can be demotivating if you want an active lifestyle. Over time, this unhealthy lifestyle can contribute to weight problems.

Emotional Factors

Emotional health and weight are correlated. Stress, depression, and anxiety can lead to emotional eating, and you may consume a diet high in calories. These mental health conditions often lead to higher levels of the "stress hormone" cortisol, which may cause fat to gather around your abdomen. You may not feel energetic or motivated to do any physical activity. If you have body image issues, you may either binge eat or restrict your eating, thus leading to weight gain or weight loss.

Medical Conditions and Medications

Hypothyroidism, insomnia, menopause, Cushing's disease, PCOS, congestive heart failure, sleep apnea, edema, metabolic syndrome, and diabetes are common conditions that may cause you to gain weight. On the other hand, cancer, hyperthyroidism, Celiac disease, diabetes, Crohn's disease, and chronic obstructive pulmonary disease (COPD) may lead to weight loss. Medications such as birth control pills, antipsychotics, antidepressants, epilepsy drugs, and beta-blockers (for high blood pressure) are also associated with weight fluctuations.

Smoking, Alcohol, and Drugs

Consuming alcohol can lead to a significant increase in calorie intake, especially if it is consumed in large amounts. It can also interfere with the body's metabolism of other nutrients and increase abdominal fat. On the other hand, nicotine in cigarettes can suppress appetite and increase metabolism, which can lead to weight loss. Some drugs are also associated with changes in appetite and metabolism and may cause weight gain or loss.  

What are the Complications of Being Overweight or Obese?

If you fall in the overweight or obese range, you are at a higher risk of many chronic health conditions than those with a healthy weight. Some of these diseases may also be life-threatening.

What are the Treatments to Lose Weight?

Your healthcare provider will diagnose obesity using your medical and family history, general physical exam, BMI, waist circumference, and other necessary tests. After that, they will prepare a weight loss plan for you which will involve changes in your diet, physical activity, and lifestyle. The goal is to reach and maintain a healthy weight to improve your overall physical and mental well-being.

Dietary Changes

• Create a calorie deficit, which means burn more calories than you consume.
• Consume nutrient-dense food low in calories, such as fruits, vegetables, whole grains, lean protein, and healthy fats.
• Eat high-fiber foods such as whole grains, fruits, vegetables, beans, and legumes to help you stay satiated for a longer time.
• Watch your portion sizes, and do not eat any food (even if it is healthy) in large quantities. You can use a smaller plate to help you eat smaller portions.
• Limit foods that are processed, fatty, and sugary as they tend to be high in calories and low in nutrients. However, do not completely ban them, as that will lead to more cravings and overeating.
• Instead of stocking junk food in your pantry, keep healthy snacks such as nuts, seeds, sprouts, and salads.
• Drink plenty of water to help you feel full and reduce your calorie intake.
• Plan your meals so you can keep a watch on your calorie intake and avoid snacking between meals.
• Practice mindful eating and pay attention to your body's hunger and fullness signals. Avoid watching TV or scrolling through your phone while eating.

Exercises

• Choose physical activities that you enjoy so that you are motivated to continue them for longer.
• Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic activity, or a mix of both per week. Swimming, cycling, walking, rowing, running, and jumping rope are a few examples of aerobic exercises.
• At least twice per week, incorporate strength training exercises such as weight lifting or bodyweight exercises.
• Stay consistent with your efforts and try to make exercise a regular habit, doing at least 3-4 sessions per week.
• With improved fitness, increase the intensity of your workouts. You may increase your workout duration or intensity or engage in newer activities to challenge your body.

Behavior Changes

• Take therapy to curb emotional eating and learn healthier ways to cope with stress or anxiety.
• Learn to monitor your diet and physical activity and cope with food cravings.
• Join support groups to find people with similar struggles related to weight.
• Practice stress-reducing activities like yoga, meditation, or deep breathing exercises.
• Find an accountability partner who can regularly help you stay on track with your weight loss goals.
• Get good-quality sleep of 7-8 hours every night.

Weight-loss Medication

Weight loss medication, also known as anti-obesity medication, helps with weight loss combined with a healthy diet, regular exercise, and behavior modifications. There are prescription drugs with different mechanisms—some work by suppressing appetite, while others affect the absorption or metabolism of nutrients.

After considering your medical history and health challenges, your healthcare provider may suggest prescription drugs if:

• You are struggling to lose weight through diet and lifestyle changes alone.
• You have obesity (BMI is greater than 30).
• You are overweight (BMI greater than 27) and have weight-related health issues such as diabetes or hypertension.

What are the Complications of Being Underweight?

If you fall in the underweight range, you are at a higher risk of many chronic health conditions than those with a healthy weight. Some of these diseases may also be life-threatening.

• Osteoporosis
• Nutrient deficiencies
• Hormonal imbalances
• Weakened immune system
• Infertility
• Anaemia
• Increased risk of infections
• Skin, hair, or teeth problems
• Increased risk of surgical complications
• Poor wound healing
• Reduced cognitive function
• Reduced muscle mass and strength
• Hypothermia
• Increased risk of mortality
• Heart problems

What are the Treatments to Gain Weight Safely?

If you're looking to gain weight healthily, here are some tips to consider:

Dietary Changes

• Try to eat five to six small meals daily instead of three large meals.
• It would help if you consumed more calories than you burn to gain weight. You can add healthy high-calorie foods to your diet, such as nuts, dried fruits, avocados, whole-grain bread, full-fat dairy products, and lean meats.
• Consume foods rich in nutrients, such as fruits, vegetables, whole grains, lean protein, and healthy fats.
• Stay hydrated by drinking enough water, milk, and fruit juice.
• Snack on healthy options such as nuts, seeds, and nut butter, as well as fruits and vegetables.
• Foods that are low in calories, such as salads and vegetables, are great for a healthy diet but may not be the best option for someone trying to gain weight. Focus on consuming more calorie-dense foods instead.

Exercise

Exercise alone may not be the most effective method for gaining weight, as it typically burns calories rather than adding them. However, exercise can help increase appetite and build muscle, which can contribute to weight gain. Resistance training, such as weightlifting or bodyweight exercises, can help build muscle mass, increasing overall body weight. Cardio exercises like running or cycling can also help improve appetite and overall calorie intake. It's important to balance exercise with a healthy diet that provides sufficient calories and nutrients to support weight gain.

What are the Healthy and Safe Ways to Maintain Your Weight?

Remember, maintaining a healthy weight is about making sustainable lifestyle changes and adopting healthy habits that you can stick with over the long term.

• Eating a well-balanced diet that includes whole foods, fruits, vegetables, lean proteins, and healthy fats can help you maintain a healthy weight.
• Be mindful of your portion sizes, and try to eat smaller meals throughout the day to help regulate your metabolism.
• Drinking plenty of water can help you feel full and reduce the likelihood of overeating.
• Regular exercise can help you maintain a healthy weight by burning calories and building muscle.
• Lack of sleep has been linked to weight gain, so getting enough quality sleep each night is essential.
• Stress can trigger emotional eating, which can lead to weight gain. Practice stress-management techniques like yoga, meditation, or deep breathing to help manage stress.
• Regularly monitoring your weight can help you adjust your diet and exercise routine to maintain a healthy weight.

When Should You See a Doctor?

If you are concerned about weight or experiencing weight-related health problems, it is always a good idea to see a doctor. Here are some specific situations in which you should make an appointment with a healthcare professional:

• If you are underweight, overweight, or obese
• If you have tried to lose weight on your own but have been unsuccessful
• If you have unexplained weight loss or weight gain
• If you are considering weight loss surgery

Your doctor can diagnose the underlying cause of your problem and then prepare an individualized weight management plan for you. Furthermore, they will connect you to a team of professionals who can help you reach a healthy weight. The various doctors and specialists for weight management include dietitians, endocrinologists, psychologists or psychiatrists, personal trainers, and bariatrician/ bariatric surgeons.

Conclusion

Your weight is an indicator of your overall health. Both extremities of weight—underweight and obesity are unhealthy for you as they increase the risk of other chronic health conditions. Besides reducing your health risks, maintaining a healthy weight has many benefits—it can improve your sleep quality, energy, mobility, mental health, and overall quality of life.

If you are trying to reach a healthy weight, you may be tempted to try out fad diets and quick-fix weight loss solutions. However, trying out weight management programs without proper guidance can do more harm than good. It is always a good idea to take your doctor's advice before you make any changes. They can help you with sustainable lifestyle changes, including a healthy diet, regular physical activity, and relaxation techniques.

In addition to seeking medical advice, it is also helpful to surround yourself with a support system that can provide motivation and encouragement throughout your weight management journey. It can include friends, family members, or a support group.

Finally, remember that everyone has unique bodies, lifestyles, and nutritional needs. Therefore, you need to set your individual weight goals. It is important to celebrate small victories along the way and not be too hard on yourself if you experience setbacks. Weight management is a process that takes time and effort, but with the right mindset and tools, it is possible to achieve and maintain a healthy weight and improve overall health and well-being.
