A new survey from Asda Online Doctor revealed that while over 1.5 million people in the UK are using these medications, a significant chunk are struggling with nutrition due to suppressed appetites. The result? Missed meals, not enough protein, and too much processed junk.
“Weight-loss medication can be transformative,” says Dr. Crystal Wyllie, GP at Asda Online Doctor, “but maintaining proper nutrition with a reduced appetite is crucial for long-term health.”
🚫 What’s Going Wrong?
According to the study:
- 37% worry they’re not getting enough nutrients.
- 21% aren’t eating enough fruits or vegetables.
- 1 in 5 aren’t getting enough protein to maintain muscle.
- 52% skip meals several times a week.
- 31% don’t know what they should be eating while on weight-loss meds.

The appetite-reducing effects of these jabs can lead people to eat far too little—or to reach for quick, unhealthy options like:
- Processed snacks (24%)
- Desserts (14%)
- Fried food (13%)
✅ So, What Should You Eat?
Healthline explains that a balanced diet should include:
- Lean proteins (think grilled chicken, tofu, or eggs)

- Fresh fruits and vegetables
- Nuts and legumes for fiber and healthy fats
