10 Key Facts and Recommendations on Obesity, Nutrition, and Weight Loss Therapies

At EndoSlim Clinic by Atlantic Gastroenterology in Brooklyn, New York, we understand that managing obesity involves more than just weight loss—it requires careful attention to nutrition and overall health. With the growing use of medications like GLP-1 receptor agonists (GLP-1RAs), it’s important to know how these treatments impact your body and what steps you can take to optimize your nutrition and wellbeing. Here are some important facts and recommendations for your weight loss journey by our Bariatric Endoscopist and Obesity Medicine Specialist, Dr. Alexander Shapsis: 

1. Widespread Use of Weight Loss Medications

Nearly 12% of Americans—about 4 million people—have used GLP-1RAs to assist with weight loss. These drugs can help patients lose up to 20% of their total body weight, though individual results vary widely.

2. Common Side Effects Are Mainly Gastrointestinal

Many patients experience gastrointestinal (GI) side effects such as nausea, vomiting, or diarrhea. While clinical studies show less than 10% of patients stop treatment due to these symptoms, real-world experiences may differ. Managing these side effects is crucial for continuing therapy successfully.

3. Nutritional Deficiencies Are Still Being Studied

GLP-1RAs significantly reduce caloric intake, but their effects on macronutrient and micronutrient levels are not fully understood. This makes monitoring nutrition an essential part of care.

4. Nutrition Education for Providers Is Limited

Many healthcare providers prescribing weight loss medications receive minimal formal training in nutrition, which can impact patient counseling and outcomes. Seeking guidance from nutrition specialists can improve success.

5. Start with Baseline Diet and Activity Assessments

Evaluating dietary habits and physical activity before starting treatment helps identify those at risk for malnutrition and allows for tailored care plans supporting weight loss and nutritional health.

6. Managing GI Symptoms Through Diet and Medication

Adjusting food choices and eating habits, and the appropriate use of over-the-counter or prescription remedies, can alleviate GI side effects. Consulting a gastroenterologist can be very helpful if you struggle with managing symptoms.

7. Ongoing Monitoring of Nutritional Status

Regularly reviewing diet changes and using lab tests to check nutrient levels ensures patients meet their macronutrient and micronutrient needs throughout treatment. Supplements can be added when necessary.

8. Incorporate Protein and Exercise to Preserve Muscle

Weight loss can lead to muscle loss if not managed properly. Ensuring adequate protein intake combined with exercise plans helps maintain muscle mass, and body composition testing can monitor changes over time.

9. Dietitians and Food as Medicine Programs Enhance Success

Working with dietitians and participating in specialized nutrition programs improves outcomes. Expanding patient access to these resources is important for widespread success.

10. Need for Better Multidisciplinary Collaboration and Research

Addressing obesity and nutrition requires collaboration across medical specialties, including gastroenterology, nutrition, and weight management. More research is needed to develop nutritional risk assessment tools tailored for obese patients.
