Losing weight is often driven by deeply personal motivations. For some, it's about feeling confident in their favorite clothes again. For others, it's reducing concerning health risks associated with obesity. Whatever your reasons, weight loss can transform your physical health, boost your energy, and build your self-confidence.

In this article, we will explore obesity and weight loss, including the risks associated with being overweight, the benefits of losing weight, and practical approaches to weight loss.

What is Obesity?

Obesity is an issue that affects both children and adults. It develops when someone carries an unhealthy amount of body fat for their height. The most common way to determine if your weight is at a healthy level is to calculate your body mass index (BMI). 1

BMI uses your height and weight to estimate your body fat. 1 The BMI guidelines for adults are as follows:

  • Below 18.5: Underweight
  • Between 18.5 and 24.9: A healthy weight
  • Between 25 and 29.9: Overweight
  • Between 30 and 39.9: Obese
  • 40 or higher: Severely obese 1

For children, BMI needs to take age into account since their bodies are still developing. The best way to determine your child’s BMI is to ask your doctor for an evaluation. 1

While BMI is a useful tool for most individuals, it does have some limitations. It primarily measures excess weight rather than specifically targeting excess fat. Therefore, individuals who have a significant amount of muscle mass, such as athletes, may have a high BMI without having excess fat. Nonetheless, BMI still serves as a valuable indication of a healthy weight for the general population. 1

Defining Weight Loss

Losing weight often comes down to a simple equation: you need to burn more calories than you consume. 2 Understanding how this works can help in your weight loss journey.

  • Caloric intake: When we eat food, our bodies convert it into energy, measured in calories.
  • Energy expenditure: The calories we burn throughout the day from exercise, basic functions like breathing, and even sleeping make up our energy expenditure. 2

Weight loss occurs when our energy expenditure consistently exceeds our caloric intake, creating an energy deficit. This deficit prompts the body to tap into stored fat as fuel, resulting in weight loss over time. 2

The key is creating an ongoing lifestyle with healthy eating patterns and regular physical activity, not jumping on the latest fad diet or program. Focus on gradual changes to your daily habits that support wellness in the long-term.

Carrying excess weight can lead to many serious health risks. Studies have found that being overweight or obese contributes to a wide range of medical issues, some of which can become life-threatening if left unchecked. 3

  • Type 2 diabetes
  • Cardiovascular disease
  • Erectile dysfunction
  • High blood pressure
  • Reduced fertility
  • Kidney disease
  • Liver disease 3

The takeaway is that obesity affects much more than just appearance or fitness level. Carrying substantial excess weight can open the door to potentially serious medical complications.

Weight Loss Benefits

Weight loss has numerous benefits, not only for your physical health but also for your mental well-being. While some benefits of weight loss are health-related, many have a direct impact on your day-to-day mood and overall quality of life.

  • Reduced risk of type 2 diabetes: Excess weight and diabetes have a close connection. Studies show that overweight or obese individuals are much more likely to develop diabetes. 4 For many, losing just five to ten percent of their body weight can make a big difference in improving insulin sensitivity, stabilizing blood sugar levels, and decreasing or eliminating the need for some medications. 5
  • Improved cardiovascular health: Being overweight makes you more prone to various heart diseases such as coronary artery disease, high blood pressure, and high cholesterol. Fortunately, even losing just five percent of your total body weight can significantly lower your chances of getting heart disease. 6
  • Improved sleep: Extra weight frequently contributes to sleep problems like insomnia or sleep apnea. Losing weight can help relieve these issues, allowing you to sleep more soundly and improve your overall sleep quality. 7
  • Improved energy levels: When you carry excess weight, your body must work much harder to complete normal daily tasks. As you shed extra pounds, your body's workload is reduced, giving you an energy boost. 8
  • Improved self-esteem: Losing weight can build self-esteem and encourage a more positive outlook on life. However, it's important to keep in mind that weight loss alone will not "cure" low self-esteem. Focusing on self-care throughout your weight loss journey is crucial.

Creating a Sustainable Weight Loss Diet

a diet plan surrounded by healthy food

When working towards weight loss, it’s crucial to develop sustainable eating habits that you can maintain long-term. Avoid extreme or fad diets that promise rapid weight loss through severe calorie restriction. These diets are often unsustainable and can even be dangerous. Instead, aim for gradual, healthy weight loss through mindful changes to your daily diet.

To help you plan your meals effectively, try incorporating the following suggestions:

  • Choose nutrient-rich foods: Opt for foods that are packed with essential vitamins, minerals, and other beneficial nutrients, while being mindful of their calorie content. By selecting more nutrient-dense options, you can provide your body with the necessary nutrients without consuming excessive calories. 9
  • Control portion sizes: A healthy diet not only involves selecting the right foods but also managing the quantity of food you consume. Eating large portions can easily lead to weight gain, so it's important to practice portion control. Start by using smaller plates to avoid the temptation of piling on excessive food. Additionally, consider using measuring cups and spoons to ensure you are consuming the appropriate amount of each food item. 10
  • Manage calories: Cutting calories doesn't have to be complicated. The key is to keep track of what you eat and strive to maintain a balance between the calories you consume and the calories you burn through physical activity. Consider using a calorie tracker app or a food logbook to help you monitor your calorie intake throughout the day.
  • Use the 20-minute rule: After finishing a meal, wait at least 20 minutes before getting second helpings. It takes time for your body’s satiety signals to kick in, so be patient and give yourself a chance to feel full before eating more. 10

Weight Loss Medications

If you have been trying to lose weight through lifestyle changes and exercise but are still struggling, talk to your doctor about prescription weight loss medications. Medication can help boost your weight loss efforts when combined with healthy habits and used under medical supervision.

To qualify for a prescription weight loss drug, you typically need to meet certain criteria, such as:

  • Having a body mass index (BMI) of 30 or higher.
  • Having a BMI of 27 or higher and struggling with obesity-related health issues like type 2 diabetes or high blood pressure. 11

The good news is that medical providers today have several weight loss treatments. Three of the most common prescription medications are:

  • Wegovy is a weekly injectable medication that reduces your appetite. It is typically used in combination with a healthy diet and exercise. 11
  • Rybelsus is an oral medication that curbs your appetite and lowers blood sugar. While not currently FDA-approved for weight loss, it may be prescribed off-label to aid weight management. 12
  • Tirzepatide is a once-weekly injection that reduces appetite and food intake. It is typically used in combination with a healthy diet and exercise. 13

Conclusion

Losing weight can change your life for the better in many ways. While it requires dedication and hard work, the rewards of improved health, increased energy, and boosted confidence make it worthwhile.

Do not get discouraged if you have struggled with weight loss in the past. Talk to your doctor about options like medication or therapy that could help you find the right path forward. The most important thing is that you take the time to explore what works for you. 

FAQs

How fast can I expect to lose weight?

Losing half a pound to two pounds per week is a healthy, sustainable weight loss rate. Losing weight any faster than this can be counterproductive and make it harder to keep the weight off. 14

When you drastically cut calories to lose weight rapidly, it causes your metabolism to slow down as your body tries to adapt to the lower calorie intake. This makes it increasingly challenging to continue losing weight and can also make it easier to regain the weight after returning to more normal eating habits. 14

What is a healthy weight goal I should aim for?

A healthy weight depends on many personal factors. To determine if you are at a healthy weight, it is best to speak with your doctor. However, you can get a general sense of your weight category by calculating your body mass index (BMI).

BMI uses a formula that divides your weight by your height. The resulting number gives you a general sense of whether your weight is low, normal, or high compared to most people of your height. 1

The following BMI categories are often used for adults:

  • BMI below 18.5 indicates being underweight
  • BMI between 18.5 and 24.9 is considered a healthy weight
  • BMI between 25 and 29.9 is categorized as overweight
  • BMI between 30 and 39.9 is considered obese
  • BMI of 40 or higher is considered severely obese 1

What is the best type of exercise to lose weight?

To lose weight in a sustainable way, the most effective exercise regimen incorporates strength training and aerobic exercise. Focusing on just one type of physical activity will not provide the same benefits as combining the two. 15

  • Weight training helps build and maintain muscle mass. Muscle is metabolically active, meaning it requires energy to function, so adding more muscle through weight training means burning more calories throughout the day, even at rest.
  • Aerobic exercise strengthens your heart and improves your stamina. Aerobic exercise also burns a significant number of calories, especially if done at a moderate or vigorous intensity. 15

By combining strength and aerobic training, you get the metabolism-boosting benefits of increased muscle mass along with an efficient, healthy cardiovascular system. 

Can stress and anxiety prevent me from losing weight?

Weight gain and anxiety have a complex relationship. While anxiety can lead to weight gain in some people, the connection isn't straightforward. Anxiety manifests in different ways, so its impact on weight varies.

There are a few key reasons anxiety and stress may cause weight gain:

  • Elevated cortisol: When you experience anxiety, your body releases the stress hormone cortisol. Cortisol causes fat storage around the midsection. This is one of the biggest reasons why chronic stress and anxiety can make it difficult to maintain a healthy weight.
  • Emotional eating: For some people, anxiety triggers overeating as a coping mechanism or because eating temporarily improves mood by releasing feel-good endorphins. While eating may provide temporary relief from anxiety, overeating leads to weight gain in the long run.
  • Fatigue: Anxiety can be emotionally and physically draining for many. You may sleep more, rest more, and be less active when anxious. With decreased activity, weight gain is more likely. 16

Regardless of the cause of weight gain, it is important to focus on maintaining a healthy diet and engaging in regular exercise. These lifestyle factors are the most effective solutions for managing weight gain associated with anxiety. 16

How important is sleep when it comes to weight loss?

Getting enough quality sleep is crucial for maintaining a healthy weight. Research has uncovered several ways that insufficient sleep can negatively impact metabolism and weight management.

  • Increased appetite: When you don't get enough sleep, your body's regulation of hunger hormones gets disrupted. For example, one study found that men who slept only four hours a night had higher levels of the hormones that stimulate appetite compared to men who slept ten hours. With an increased appetite, you are more prone to overeating and weight gain.
  • Decreased metabolism: Poor or limited sleep commonly leads to problems with blood sugar control and insulin resistance. Your body cannot process energy from food as efficiently. This makes it more difficult to maintain a healthy weight.
  • Decreased physical activity: Lack of sleep reduces your energy levels and motivation for physical activity. Feeling excessively tired can make exercise and sports seem less appealing and even unsafe. 17

Are there ways I can boost my metabolism?

Having a fast metabolism is largely attributed to a person's basal metabolic rate (BMR). Your BMR is essentially the amount of energy, or calories, your body needs to perform basic life-sustaining functions while at rest. This includes involuntary actions like breathing. 18

A few factors can give your metabolism a boost:

  • Muscle Mass:Muscle is more metabolically active than fat, meaning that having more muscle results in burning more calories even when you're not actively exercising.
  • Sleep:Quality sleep is essential for the body to rejuvenate, regulate hormones, and support metabolic processes. During sleep, your body repairs and grows muscles, aiding in weight management and overall health.
  • Water intake: Enzymes responsible for breaking down nutrients require water to facilitate chemical reactions. Without enough water, these processes may slow down, affecting your metabolic efficiency. 18
