For many people trying to shed unwanted weight, the question of how quickly results can happen is always top of mind. Whether you’re preparing for a holiday, a big event, or simply feeling motivated to make a change, it’s natural to wonder: how to lose a stone in a month?

At Vivo Pharmacy, we’re seeing more people ask whether weight loss injections like Wegovy can help achieve rapid results. While these medications are clinically proven to support significant weight loss, there are important considerations about how they work, how quickly they act, and how to use them safely. Here’s what you need to know.

What Are Weight Loss Injections?

Weight loss injections such as Wegovy (semaglutide) belong to a class of medicines called GLP-1 receptor agonists. These medications work by mimicking a hormone in the body that helps regulate appetite, digestion, and insulin levels.

By increasing satiety and slowing down the digestive process, these injections help you feel fuller for longer and reduce cravings. When combined with a calorie-controlled diet and increased activity, they can lead to substantial and sustainable weight loss over time.

Wegovy has been approved in the UK for weight management in patients with…

A BMI of 30 or more (obese) or a BMI of 27 or more (overweight) with a weight-related condition such as high blood pressure, type 2 diabetes, or high cholesterol.

So… Can They Help You Lose a Stone in a Month?

It’s possible—but it’s not typical or recommended for most people. Weight loss injections like Wegovy are designed to support gradual and safe weight loss, usually over a period of several months. Clinical trials show that most users can lose up to 15% of their body weight over 68 weeks. This works out to an average of 1–2 pounds per week, which is in line with safe weight loss guidance.

That said, some people—especially those with higher starting weights or rapid early appetite reduction—may see a more accelerated response in the first month. However, this is the exception rather than the rule.

More importantly, rushing weight loss increases the risk of side effects, nutrient deficiencies, or unsustainable habits. With medication like Wegovy, starting low and increasing the dose gradually is key to avoiding nausea, bloating, or other digestive discomfort.

How Are Weight Loss Injections Used?

Wegovy is taken once a week via injection, using a pre-filled pen. The dosage starts low and gradually increases over several weeks:

• –> Week 1–4: 0.25 mg

• –> Week 5–8: 0.5 mg

• –> Week 9–12: 1 mg

• –> Week 13–16: 1.7 mg

• –> Week 17 onwards: 2.4 mg (maintenance dose)

Because the full therapeutic dose isn’t reached until week 17, the strongest weight loss effect often happens after the first month, not during it. That’s why most patients notice modest progress at first, followed by more noticeable results later.

Is Losing a Stone in a Month Safe?

Losing a stone (approximately 6.3 kg or 14 pounds) in just four weeks is a very ambitious goal. For some people, particularly those with a high BMI, it may be medically safe under supervision. But for others, it could put undue strain on the body—especially if achieved through crash dieting or extreme calorie restriction.

The NHS and public health bodies recommend losing 1–2 pounds per week as a sustainable, safe target. That equates to 4–8 pounds per month. Anything faster should only be attempted under clinical guidance.

At Vivo Pharmacy, we don’t just hand out prescriptions—we work with you to create a tailored weight loss plan that prioritises safety, long-term health, and ongoing support.

When Should You Consider Weight Loss Injections?

You may be a suitable candidate for Wegovy or similar medication if you:

• –> Have a BMI of 30 or more (or 27+ with health conditions)

• –> Have tried lifestyle changes without success

• –> Need help managing appetite or food cravings

• –> Are committed to combining medication with healthy eating and physical activity

We offer private consultations at Vivo Pharmacy to assess your eligibility, check for any underlying medical issues, and provide guidance on the first steps.

What If You’re Travelling or on a Tight Deadline?

If you’ve got a holiday or major event coming up soon, we understand the desire to slim down quickly. In that case, we recommend focusing on realistic, achievable goals in the time you have—such as losing half a stone or improving your energy levels and confidence.

Medication can still help, even in the early stages, by resetting your appetite and boosting motivation. But the goal should be long-term success, not just short-term numbers.
