What is GLP-1 and how does it work
According to Dr Alok Chopra, "GLP-1 medicines help control blood sugar and reduce appetite. They slow down how quickly food leaves your stomach, helping you feel fuller for longer and eat less naturally."
He explained that these medications signal fullness to the brain, slow stomach emptying and help regulate blood sugar levels. However, he stressed that "GLP-1 is a tool, not a magic solution. Long-term success depends on the habits you build along the way."
Who is GLP-1 meant for
Dr Chopra said GLP-1 medications are generally recommended for people with:
- Obesity (BMI over 30 kg/m²)
- Overweight (BMI of 27 kg/m² or higher) with health conditions such as:
- Type 2 diabetes
- PCOS
- Fatty liver disease
- Sleep apnoea
- High blood pressure
He added that “GLP-1 should be taken only after a complete medical evaluation and on the advice of a doctor, particularly for those who struggle to lose weight despite healthy eating and regular exercise.”
Who should avoid GLP-1 medications
Dr Chopra cautioned that GLP-1 medications are not recommended for:
- Pregnant or breastfeeding women
- People with a personal or family history of medullary thyroid cancer or Multiple Endocrine Neoplasia type 2 (MEN2)
- Those with a previous episode of pancreatitis
- People with gastroparesis or conditions that delay stomach emptying
What should you do while taking GLP-1
To maximise results and minimise side effects, Dr Chopra advised:
- Prioritise protein to preserve muscle during weight loss.
- Stay hydrated by drinking enough water.
- Include strength training to maintain muscle mass and support metabolism.
- Eat slowly, choosing smaller meals that are easier to digest.
Common side effects of GLP-1
According to Dr Chopra, some of the most common side effects include:
- Nausea, which usually settles within the first few weeks.
- Constipation, which can improve with adequate hydration and fibre intake.
- Bloating, often reduced by eating smaller, slower meals.
- Reduced appetite, making it important to focus on nutrient-dense, protein-rich foods.
Will the weight come back after stopping GLP-1
Dr Chopra said the answer depends largely on lifestyle habits. "Yes, if healthy habits don't stay with you. GLP-1 helps reduce appetite while you're taking it. Lasting results come from the habits you build alongside the medication."
He concluded with a reminder that "You should rewire your goals from losing weight to building a healthy, happy body."
