Obesity is neither a cosmetic issue nor a psychological problem. It is very important for our patients to understand that obesity is a CHRONIC PROGRESSIVE MEDICAL DISEASE. Our understanding of obesity, energy metabolism and weight control has greatly evolved over the past few years. We now understand that many hormones control body weight and obesity is the result of an imbalance in these complex hormonal systems.

Therefore, obesity is no longer viewed as a consequence of over-eating, self-indulgence or lack of self-control. Rather, obesity is the result of multiple environmental and genetic factors that disrupt a variety of hormonal systems that control body weight and energy metabolism. The disruption of these hormones results in the progressive body fat accumulation.

It is important to know that diet and exercise, unlike weight loss surgery, are less likely to restore the underlying hormonal disruption that has led to obesity in the first place. Accordingly, overweight patients who loose excess weight by decreasing calorie intake, or increasing calorie expenditure through exercise, tend to regain their lost weight. This cyclical weight loss and regain also known as yo-yo diet is not only counterproductive but also harmful. It leads to frustration, disappointment and guilt feeling. Some studies have suggested increased risk of stroke and hypertension.

At Houston Weight Loss Surgery Center, we recommend changing your eating habits in a reasonable, realistic and intelligent fashion to avoid the yo-yo dieting effect. We emphasize to our patients the importance of changing what and when they eat before simply decreasing their total daily calorie intake.

In fact, not all calories are created equal and the first step towards healthy living and weight loss is eating clean food. Our patients are asked to stop completely all form of processed food like potato chips and candies. Throw away all sweets from your house. Sugar and white flour increase insulin resistance and result in weight gain. Therefore, we ask our patients to decrease their meal carbohydrate content while increasing their consumption of lean protein and good fats like avocados and nuts. Lean protein and healthy fats increase satiety, curb excessive appetite, and increase metabolism especially the setting of insulin resistance.

Once these recommendations are followed, patients are asked to start reducing their total daily caloric intake. Our patients are encouraged to keep a calorie count, pay attention to hunger cues, adopt intermittent fasting and avoid eating for comfort and out of boredom.
