What is Obesity?
Obesity is a medical condition characterized by an excessive amount of body fat. Traditionally, it has been measured using the Body Mass Index (BMI), a simple calculation based on a person’s weight and height (Pounds/[Inches^2] x 703). While BMI has historically been widely used, it is increasingly being scrutinized as an outdated tool that doesn’t account for muscle mass, bone density, and other factors. Using BMI, cutoff’s are broken down as such:
Under Weight: <18.5
Healthy: 18.5-24.9
Overweight: 25-29.9
Obese: 30-39.9
Alternative measures such as body fat percentage, waist-to-hip ratio, and advanced imaging techniques are increasing in popularity in conjunction with BMI and even as stand-alone measures.
Brief Science
1. Genetics
Genetics play a significant role in obesity. Studies have shown that 40-70% of a person’s predisposition to obesity is inherited. Certain genes can affect how your body processes food and stores fat. If obesity runs in your family, you may be at higher risk, but it’s not the sole determinant.
2. Metabolism
Metabolism is the process by which your body converts food into energy. People with a slower metabolism may burn fewer calories at rest and during activity, which can contribute to weight gain. Factors like age, muscle mass, and hormonal imbalances can affect metabolic rate. Read my article on supercharging your metabolism here for a great breakdown about what metabolism is and how to boost it!
3. Environment and Lifestyle
The environment we live in greatly impacts our eating and physical activity habits. Easy access to high-calorie, low-nutrient foods, sedentary lifestyles, and lack of safe spaces for physical activity all contribute to the obesity epidemic. Easy access to high quality nutrient dense food, decent outdoor spaces, and safe spaces for physical activity can contribute to leading healthier lifestyles. Sometimes you can’t change things like the house or city you live in, but you can always alter the environment within your home.

4. Behavior and Psychological Factors
Eating behaviors and psychological factors, such as stress, emotional eating, and lack of sleep, can influence weight gain. Chronic stress can lead to hormonal changes that increase appetite and cravings for unhealthy foods.
5. Medical Conditions and Medications
Certain medical conditions, like hypothyroidism and polycystic ovary syndrome (PCOS), can lead to weight gain. Additionally, some medications, including antidepressants and corticosteroids, may cause an increase in appetite or fluid retention, contributing to obesity.
Health Risks Associated with Obesity
Obesity is linked to several serious health conditions, including:
- Type 2 Diabetes: Excess fat can cause insulin resistance, leading to high blood sugar levels. See our latest article here.
- Heart Disease: Obesity increases the risk of high blood pressure, high cholesterol, and other factors that contribute to heart disease.
- Stroke: The same risk factors that contribute to heart disease can also increase the risk of stroke.
- Certain Cancers: Obesity is associated with an increased risk of cancers, such as breast, colon, and endometrial cancer.
- Sleep Apnea: Excess weight can cause the airway to become blocked during sleep, leading to breathing problems.
Managing Obesity
Managing obesity involves a combination of lifestyle changes, medical interventions, and sometimes, surgery. Here are some evidence-based strategies:
1. Healthy Eating
Adopting a balanced diet rich in whole foods, such as fruits, vegetables, lean proteins, and whole grains, is essential. Reducing intake of processed foods, sugary beverages, and high-fat foods can help manage weight.
2. Regular Physical Activity
Regular physical activity is essential to anyone’s health! But going from a sedentary lifestyle to the recommended 150 minutes of moderate-intensity exercise or 75 minutes of high-intensity exercise per week can feel a bit daunting. My best piece of advice here is to think of movements you enjoy doing. Is it dancing, swimming, walking? Whatever it is, try incorporating that activity…the one that actually brings you JOY…into your life. It will be much easier to stay consistent with this type of activity than it will to jump into doing something that intimidates you or that you loathe entirely. And remember…consistency is key! Try to include a mix of cardio and strength training to boost metabolism and preserve muscle mass.
3. Behavioral Changes
Developing healthy eating habits and coping mechanisms for stress and emotional eating can make a significant difference. Techniques like mindful eating and cognitive-behavioral therapy (CBT) are effective. And if you find yourself struggling in the mental health realm, take care of yourself by seeking out the help you need! There is absolutely no shame in therapy or in asking for help!
4. Medical Treatment
In some cases, medications prescribed by a healthcare provider can aid in weight loss. These medications work by suppressing appetite or blocking fat absorption. To be completely honest, I am somewhat torn on this one. On one hand, I do believe that it can be a great kickstart for someone who is truly struggling with significant weight issues that are compromising their overall health and wellbeing. On the other hand, I don’t believe in using these long term, and often when habits and lifestyle changes are not addressed, weight comes on just as quick as it goes off. I guess what it comes down to is my belief that these types of medications should only be used if they are monitored by a licensed professional, used in the short term, and are accompanied by significant lifestyle changes.
5. Surgery
For individuals with severe obesity who haven’t had success with other treatments, bariatric surgery may be an option. Procedures like gastric bypass or sleeve gastrectomy can help reduce the amount of food you can eat and absorb. However, surgery is not a quick fix and requires significant lifestyle changes for long-term success.
Psychiatric Requirements for Surgery
Before undergoing bariatric surgery, candidates often need to meet certain psychiatric requirements. This typically involves a thorough psychological evaluation to ensure they are mentally prepared for the significant lifestyle changes post-surgery. Issues such as untreated depression, binge eating disorders, or substance abuse need to be addressed to increase the likelihood of success. Psychological support and counseling can also play a crucial role in the post-surgery period to help patients adjust to their new lifestyle.
Conclusion
Obesity is a complex condition influenced by various factors, including genetics, metabolism, environment, behavior, and medical conditions. Understanding these factors can help demystify obesity and highlight the importance of a comprehensive approach to managing it. By adopting healthy eating habits, staying active, making behavioral changes, and seeking medical advice when necessary, individuals can improve their health and reduce the risks associated with obesity.
