Introduction: Side Effects Don’t Have to Sabotage Results
GLP-1 medications, like semaglutide, are powerful tools for weight loss, but some individuals may experience side effects such as nausea, mild digestive issues, or temporary fatigue.
Specialist trainer David Paul emphasises that side effect management is key for maintaining compliance, continuing exercise, and achieving sustainable results.
Common Side Effects of GLP-1
Nausea or mild vomiting
Diarrhoea or constipation
Reduced appetite (expected)
Mild fatigue or low energy during dose adjustments
These are often temporary and can be mitigated with proper strategies.
Tips to Manage Side Effects
1. Gradual Dose Titration
Follow your prescribing schedule carefully
Allow your body to adjust before increasing dose
Helps minimise nausea and digestive discomfort
2. Meal Timing & Composition
Eat smaller, frequent meals
Include protein, fibre, and healthy fats to support digestion
Avoid greasy or highly processed foods early in treatment
3. Hydration
Drink plenty of water throughout the day
Herbal teas or electrolyte drinks can help with mild GI issues
4. Exercise Adjustments
Start with low-impact movement during initial weeks
Avoid overly intense workouts if energy or nausea is present
Progress gradually as side effects subside
Maintaining Compliance
Consistency with medication, nutrition, and exercise is essential for results:
Track your medication schedule to prevent missed doses
Plan meals and snacks to align with appetite changes
Schedule exercise around energy levels to maintain consistency
Seek support from a professional programme to stay on track
“Side effects are temporary and manageable. Following a structured plan keeps you progressing safely,” says David Paul.
When to Seek Professional Advice
Persistent nausea, vomiting, or severe digestive issues
Rapid weight loss or unexpected fatigue
Any concerns about blood sugar, heart rate, or other health issues
Always consult your healthcare provider for personalised advice.
