Best Nuts To Eat For Weight Loss
Nuts can be a nutritious part of a weight loss plan when eaten in controlled portions, as they're rich in protein, healthy fats, and fibre that help you feel fuller for longer. However, nuts are calorie-dense — portion control matters. If you're looking to lose weight in the UK, combining smart food choices with professional support gives the best results. For eligible adults, prescription weight management medications like Mounjaro and Wegovy are now available through the NHS and private clinics, alongside dietary changes.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Nuts For Weight Loss And Prescription Medication Options
While nuts like almonds, walnuts, and pistachios are excellent choices for weight management — offering around 160–200 calories per ounce with good protein and fibre content — they work best alongside structured weight loss support. For adults in the UK with a BMI of 30 or above, or 27–29.9 with weight-related health conditions like type 2 diabetes or high blood pressure, prescription weight loss medication is now available. Options include Mounjaro (tirzepatide), a dual GIP/GLP-1 injection, and Wegovy (semaglutide), a GLP-1 injection — both licensed for weight management. Clinical trials showed Mounjaro helped participants lose an average of 15–21% of their body weight, whilst Wegovy supported approximately 15% average loss. These work alongside reduced-calorie diet and physical activity.

NHS Vs Private Access To Weight Loss Support
In the UK, prescription weight loss medication is available through two routes. NHS access is via referral to specialist tier 3 weight management services — waiting times vary significantly by region. Private access is through a GPhC-registered online clinic following a clinical assessment, typically available within days. Both require a prescription from a UK-licensed prescriber. Your GP can advise on NHS eligibility and referral, or you can explore private options independently. Either route pairs medication with lifestyle changes — including sensible food choices like portion-controlled nuts — for sustainable weight loss results.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Which nuts are best for weight loss?
Almonds, walnuts, pistachios, and Brazil nuts are excellent choices — they're high in protein and fibre, which support satiety. Almonds contain about 6g protein per ounce. Keep portions to a small handful (around 30g) to manage calorie intake. Pair with whole grains and vegetables for balanced meals.
Can I lose weight eating nuts regularly?
Yes, if eaten in controlled portions as part of a calorie deficit. Nuts provide healthy fats and nutrients, but they're calorie-dense at 160–200 calories per ounce. They work best combined with physical activity and structured eating patterns. For significant weight loss, many UK adults benefit from professional support.
What's the difference between Mounjaro and Wegovy for weight loss?
Both are prescription injections available in the UK for eligible adults. Mounjaro (tirzepatide) uses a dual GIP/GLP-1 mechanism, with a maximum dose of 15mg weekly. Wegovy (semaglutide) is a GLP-1 injection, maximum 2.4mg weekly. Clinical trials showed similar average weight loss outcomes. Your GP or prescriber will advise which is appropriate for you.
How do I access prescription weight loss medication on the NHS?
Ask your GP for referral to your local specialist weight management service (tier 3). Eligibility typically requires a BMI of 30 or above, or 27–29.9 with weight-related health conditions. NHS access varies by region and waiting lists can be lengthy. Private online clinics offer faster access if you meet eligibility criteria.
Can I use nuts if I'm taking Mounjaro or Wegovy?
Yes. These medications slow gastric emptying and reduce appetite, so you may naturally eat smaller portions. Nuts remain nutritious — portion control is still important. Continue balanced eating with vegetables, proteins, and whole grains. Your prescriber or dietitian can give personalised guidance on food choices whilst taking weight loss medication.
