Weight loss medications change more than your weight
“Weight loss medication can be genuinely life-changing. But without the right nutritional support, it can have adverse effect on your health - from muscle mass and bone density loss, to nutrient deficiencies and strain on your liver and gallbladder. That’s why we work with women on GLP-1s to monitor what's changing inside and build a nutrition plan that protects their health while they lose weight. ”
- Peach Founder, Flora Budenberg (mBANT, CNHC, IFMCP)
What’s happening in your body on weight loss medication
GLP-1 medications can create changes you can’t always see or feel - but they matter for long-term health
Nutrient intake
When you eat less, you might take in fewer vitamins and minerals. This can lead to deficiencies in iron, B12, Vitamin D, Zinc and others.
Gallbladder & liver health
Rapid weight loss and GLP-1 medications can increase the risk of gallstones and other gallbladder issues in some people, as well as affect liver function.
Digestion & gut health
GLP-1s slow your digestion - it’s part of how they work. They can also cause bloating, nausea and change in bowel habits.
Body composition
Weight loss can include muscle mass loss alongside fat. The right nutrition can help protect your strength and energy.
Energy and mood
Changes in blood sugar levels, calorie intake and nutrient status can all affect how you feel day to day - including energy, mood and focus.

GI 360 comprehensive gut test
Weight loss medications slow your digestion - that's part of how they work. But this can lead to bloating, nausea, constipation, diarrhoea, and changes in your gut microbiome. If you're experiencing digestive symptoms on weight loss medication, the GI 360 stool test can give us a detailed picture of what's happening in your gut - from bacterial balance and inflammation markers to how well you're breaking down and absorbing food. Your practitioner uses the results to build a targeted protocol to get your digestion working properly alongside your medication.
GI 360 gut test: £355 (incl. delivery of test kit)
Frequently asked questions
-
No. Peach is a nutritional therapy clinic, not a prescribing service. We work alongside your existing prescriber to make sure the rest of your health is supported while you’re on medication. Think of us as the nutritional arm of your care team.
-
Most GLP-1 prescribers focus on safety checks - is the medication causing any immediate harm? That’s important, but it’s not the same as understanding how your nutrient levels, gut health, gallbladder function etc. are being affected. Our blood panel looks at a broader picture, and our practitioners interpret the results through a functional nutrition lens to give you a personalised plan - not just a report.
-
If you do decide to take a blood test, this requires a venous blood draw, which can be done at one of our partner phlebotomists across the UK. We’ll arrange everything for you after your discovery call.
-
Absolutely. In fact, getting a baseline picture of your health before starting medication is really useful - it means we can track changes over time and ensure your body is being supported throughout the process.
-
Our blood panel is £185 (incl. blood draw at a partner clinic) and our comprehensive gut test is £355 (incl. test kit delivery). Practitioner sessions start from £130. The right combination depends on your symptoms, your goals, and how much support you want - some clients start with a blood test and a single consultation, others choose to add gut testing and ongoing sessions. Your practitioner will talk you through the options on your free discovery call so you can decide what feels right for you. There's no obligation to commit to anything before that conversation.
