How Long Does It Take to Lose 2 Stone? A Realistic Guide

Losing 2 stone (approximately 12.7 kg) can have a profound effect on your health, confidence, and quality of life. It’s a common target for people looking to reduce the risk of conditions like type 2 diabetes, high blood pressure, or joint pain. But how long does it take to lose 2 stone — and what’s the best way to go about it?

At Junction Pharmacy, we support people on all types of weight loss journeys — whether through lifestyle changes, medication, or a combination of both. In this guide, we’ll explore how long it typically takes to lose 2 stone through diet and exercise alone, compared to using medical support such as weight loss injections like Mounjaro.

Losing 2 Stone Through Diet and Exercise Alone

For those relying on lifestyle changes, the NHS recommends aiming for a safe and sustainable weight loss of 1 to 2 pounds (0.5 to 1 kg) per week. Based on this, losing 2 stone could take:

• –> 6 to 7 months at 1 lb (0.5 kg) per week

• –> 3 to 4 months at 2 lbs (1 kg) per week

This is a healthy and achievable pace that allows your body to adjust gradually, making long-term weight maintenance more likely. However, this timeline can vary depending on:

• –> Your starting weight and BMI

• –> How consistent your diet and activity levels are

• –> Hormonal health or metabolic conditions

• –> Stress, sleep, and lifestyle factors

• –> Support systems and motivation levels

To support this approach, a structured plan combining calorie control, balanced nutrition, and regular physical activity is essential. At Junction Pharmacy, we can help you create a realistic plan and track your progress along the way.

What About Weight Loss Injections Like Mounjaro?

Weight loss medications, particularly GLP-1 receptor agonists like Mounjaro (tirzepatide), can significantly enhance your results when combined with healthy lifestyle changes. These medications work by mimicking gut hormones that help regulate appetite, slow digestion, and improve blood sugar control — making it easier to eat less and feel full for longer.

Clinical studies show that patients using Mounjaro can lose up to 20% of their body weight, depending on dosage and consistency. This means that, for someone needing to lose 2 stone, the timeline could be much shorter than with lifestyle changes alone.

On average, many patients lose around:

• –> 1.5 to 2.5 lbs (0.7 to 1.1 kg) per week in the first few months

• –> 2 stone within 3 to 4 months, depending on starting weight and response to treatment

This can vary widely, of course. Some people lose weight more gradually, especially if they’re starting at a lower BMI or working to manage side effects.

Which Method Is Best?

There’s no one-size-fits-all answer. Weight loss with diet and exercise alone is absolutely possible, but it can be slow-going and challenging to maintain — especially if your appetite, hormones, or health conditions are working against you.

Medications like Mounjaro offer a clinically proven boost to help you break through plateaus, manage hunger more effectively, and see faster results. However, injections should always be part of a comprehensive weight loss plan that includes support with food, movement, and habit-building.

At Junction Pharmacy, we guide patients through both approaches — with or without medication — offering personalised advice and accountability.

Tips for Losing 2 Stone Safely and Sustainably

No matter which route you take, these principles can help ensure your success:

Set realistic goals: Aim for slow, steady progress rather than quick fixes

Stay active: Combine cardio and strength training to protect muscle and boost metabolism

Focus on protein and fibre: These nutrients help control hunger and stabilise blood sugar

Track your habits: Use a journal or app to monitor food, movement, and mood

Seek support: Whether from friends, family, or your pharmacy team, encouragement matters

Be patient: Weight loss isn’t linear — expect plateaus and fluctuations along the way
