Weight Loss

What is Healthy Weight?

A healthy weight is about more than your appearance. Maintaining a weight that is appropriate for your height and build helps your body function more efficiently. Studies show that individuals experience improved blood pressure, better cardiovascular health, and less incidence of Type 2 Diabetes when their weight is in a healthy range1,2. The digits on the scale are just one factor in your overall health, but they are important. The team at DFW Bariatric Institute is dedicated to helping patients in Dallas and Fort Worth reach their weight loss goals in order to live healthier, more active lives.

Body Mass Index (BMI)

The medical community uses Body Mass Index, or BMI, as a measurement tool to evaluate if a patient is at a healthy weight. BMI is determined using weight, height and gender. If you are familiar with the concept of BMI, you may have heard criticism that it is an inaccurate way to assess health; that may be true for professional athletes who carry a muscle mass that is significantly above the norm. However, for the majority of people BMI is a widely accepted tool to evaluate body weight.

What does your BMI mean?

BMI < 20 under weight
BMI 20-24.9 healthy weight
BMI 25-29.9 over weight
BMI 30-34.9 obesity
BMI 35-39.9 severe obesity
BMI 40-49.9 morbid obesity
BMI > 50 super morbid obesity

Health Risks Associated With Being Overweight

Scientific studies have found that a BMI over 30 correlates to a higher incidence of chronic disease3. The conditions that are attributed to or exacerbated by excess weight are called comorbidities. The following comorbidities are associated with obesity4:

Research also indicates that several types of cancer are also associated with obesity5. People with obesity may be at higher risk for breast cancer, colon cancer, uterine cancer, pancreatic cancer and esophageal cancer. Obesity can also have a negative effect on fertility for both men and women because hormone levels, sperm production, and ovulation may be altered due to obesity6. In addition to the impact to physical health, obesity may also increase the risk of mental health disease such as anxiety and depression7. At DFW Bariatric Institute, we have been honored to help many people find a path to better health. Our patients often report that they feel healthier, happier and more in control of their lives.

The Cost of Obesity

People struggling with obesity may face personal costs between $9,000 and $17,000 higher than people living at a healthy weight8. These costs are associated with higher medical expenses, including lost wages due to chronic health issues, higher insurance prices, and the cost of medical treatment and prescription drugs for comorbidities. Studies have also shown that people with obesity may encounter discrimination in the workplace which can lead to lower wages9.

Understanding Obesity

The Centers for Disease Control and Prevention (CDC) estimates that more than one third of adults in the U.S. are obese10. There are many factors that contribute to obesity, but it is more complicated than many people believe, because it is not simply a matter of willpower and diet. Certain risk factors including gender, age, genetics, family history, lifestyle, and even location can increase the likelihood that a person will become obese. However, just because you have risk factors does not mean that you are destined to struggle with obesity. Physical activity, diet and help from a medical professional can counteract risk factors to help you live a healthier and more active life.

The Science Behind Weight Loss

The human body is incredibly complex. There are some factors that contribute to weight which are in your control, but there are also some that aren’t. Your body has a basal metabolic rate (BMR) which is the rate at which your body burns calories sustaining bodily functions such as breathing and circulation. There are also intricate processes for regulating weight that involve hormones, organ systems, and brain function. If one of these components is disrupted, excess weight can accumulate, and since the body may be hardwired to store weight, losing it is much harder than gaining it. Quick fixes such as fad diets cannot restore balance to the body – only comprehensive lifestyle changes can.

Breaking The Weight Loss and Regain Cycle of Dieting

Many people who struggle to lose weight experience fluctuations in weight, sometimes known as weight cycling or yo-yo dieting. Studies show that two thirds of people who lose weight through diet and exercise regain the weight within one year, and of those who don’t, many regain within 5 years11. Repeated weight loss and gain can cause health issues and make it more difficult to lose weight in the future12.

Find A Diet That Works For You

Which Diet is Right for You?*

If you’re trying to lose weight you may be overwhelmed by conflicting advice about which foods to eat and which foods to avoid. Most medical professionals and diet experts agree that a healthy approach includes whole foods such as vegetables and lean protein while limiting sugar and saturated fats. The best diet is one that you can incorporate into a lifelong healthy lifestyle. Get the details on some of the specific diet plans you may hear about:

How a Registered Dietitian Can Help You Lose Weight

With so much information available, it can be helpful to talk to a nutrition expert about your individual needs and goals. But who should you look to for advice? Your doctor of course, but they may not have the resources to provide you with a detailed plan tailored for you. That’s where a registered dietitian comes in. There are many types of nutrition experts; registered dietitians have completed specific coursework, degrees, and accredited programs and have been licensed by the state. A registered dietitian who specializes in weight loss can help you make food choices, find new recipes, and optimize your diet with a personalized weight loss plan.

The Role Of Exercise in Weight Loss

The Role of Exercise in Weight Management

Regular physical activity is an important part of a healthy and active life. Studies show that exercise is a key component in maintaining weight loss and improving overall health.13 New research also indicates that exercise may be more important to maintaining weight loss than previously believed. In addition to promoting weight loss, regular exercise can also reduce the risk of certain types of cancer and cardiovascular disease by up to 30%.14 The key to a successful workout regimen is consistency.

Tips for Sticking to a Fitness Routine

The first step in a successful fitness routine is identifying exercises that are a good match for your ability, personality and lifestyle. If you’re outgoing and like dancing, then you’re more likely to enjoy a zumba class than a solo run. If you have mobility issues, then a chair yoga class or water therapy session could be a great place to start. Busy parents can find free online workout videos to fit into their schedule. Once you choose your routine, here are some tips for staying on track:

  1. If you join a gym, choose one that is close to your home or workplace.
  2. Schedule your workouts on a calendar, just like you would important appointments. (Early morning workouts can be easier to stick with since they are less likely to be interrupted by other events.)
  3. Find a friend to workout with and hold each other accountable.
  4. Make a playlist of your favorite up-tempo songs or get a good audiobook to listen to while you workout.
  5. Set a workout goal such as walking 50 miles per month or working your way up to a certain number of pushups. When you meet your goal, give yourself a reward such as new workout clothes, a fitbit, or a spa day.

Types of Exercise for Weight Loss


Surgical/Non-Surgical Weight Loss Options

Weight Loss Surgery

The cycle of weight loss and regain that many dieters encounter is controlled by more than just willpower. Metabolic, genetic and environmental factors keep healthy weight maintenance out of reach for many people. Some experts believe that up to 95% of people who lose weight through diet and exercise will regain the weight.15 For people frustrated by the struggle of losing weight and maintaining weight loss, and for people with weight related health concerns, weight loss surgery is an option. Weight loss surgery can save lives, and contrary to some perceptions, it is not the easy way out.

Weight Loss Surgery is an Effective Treatment for Obesity

Studies show that the majority of weight loss patients maintain their weight loss years after surgery.16 Additionally, weight loss surgery such as gastric sleeve has been proven to improve diabetes; 70% of gastric sleeve patients saw an improvement or complete remission of Type 2 diabetes after surgery.17 Weight loss surgery is a powerful tool that can help people live healthier lives. In addition to restricting food intake, weight loss surgeries such as gastric sleeve or gastric bypass can also reduce the hormone ghrelin, which regulates cravings and hunger.18 The patients who have success after weight loss surgery are the ones who commit to changing their eating and activity habits to embrace lifelong lifestyle changes.
