Answers to your burning questions about Mounjaro and other GLP-1 therapies!
— 01
The moment when you’re approved for GLP-1 therapy is so exciting – but also probably a bit scary as you’re stepping into the unknown. Self injection – and all those awful stories about side effects that you’ve seen on YouTube!
The key side effects to be aware of at this starting dose are…

Everyone talks about it. But ow do I avoid it? Losing weight on GLP-1s is easy – deceptively easy. But without a diet that proritises protein and fibre and includes regular resistance training – all of which help to preserve muscle mass – you’re likely to be storing up a bunch of problems for later.

You know that feeling at the end of a leisurely meal at a restaurant, where you feel comfortably full – and you could eat more, I guess, but you could take or leave it? That feeling is, of course, ‘satiety’.
GLP1 therapies trigger a feeling of satiety. They work by mimicking the body’s natural satiety signal- GLP1.
That’s mostly what you need to know as it explains a lot of the symptoms.
Losing weight on GLP-1s is easy - deceptively easy. It's keeping it off that's the issue. The solution? Consistent exercise and excellent diet throughout the treatment, setting yourself up optimally for easier weight management in the future
