On a GLP-1 injection

Appetite down,
nutrition sorted.

When you can only manage a little, make it count. Four balanced meal replacements protect your protein and nutrient intake.
Protect your muscle

Can I use meal replacements with injections like Ozempic or Wegovy?
Yes — meal replacements are highly recommended alongside GLP-1 weight-loss injections. They help ensure you still get adequate nutrition, especially protein, despite a reduced appetite. Our products are formulated to complement the effects of medications like Ozempic, Wegovy and Mounjaro.
Why is an 800 kcal plan recommended with weight-loss injections?
An 800 kcal plan strikes a good balance — rapid weight loss while still delivering essential nutrients. It suits people on injections because it works with the appetite-suppressing effect while helping to prevent nutrient deficiencies.
How do meal replacements prevent protein deficiency?
Our meal replacements are high in protein, so you can hit your daily protein target even when you're eating far less. That matters on medication, because a suppressed appetite can otherwise leave you well short of the protein your body needs to protect muscle.
How long can I follow the 800 kcal plan?
We recommend up to 12 weeks alongside your medication. Always consult your healthcare provider — they may advise adjustments based on your health and how you're responding to the injection.
Will I feel hungry on 800 kcal while on medication?
Most people find the medication has already reduced their appetite, so four meal replacements spread across the day feel comfortably filling. Space them out, keep your fluids up, and don't skip meals even on the days you don't feel like eating.
Do I need to tell my GP or prescriber?
Yes — please keep your GP or prescriber informed about your diet and any changes to your medication or dose. We can provide a letter for your appointment on request.
Can I use plant-based milk with the shakes?
Yes. Unsweetened soya milk works best nutritionally and blends well. Other plant milks are fine too — just check the calories, as some are higher than skimmed milk.
Is the Medication Support Plan suitable for everyone?
No. It is not suitable for anyone under 18, pregnant or breastfeeding, or with a BMI below 25. If you have a medical condition such as type 2 diabetes, please check with your GP before starting.
