According to data from randomised controlled trials, Ozempic tends to support immediate weight loss.

Semaglutide reduces appetite and hunger, helping you eat fewer calories; this effect is almost immediate.

However, you might notice the effect of lower hunger wearing off after 4-5 days post-injection in the first month of taking Ozempic.

It can take 4-5 weeks for Ozempic to reach a level in the body we call a steady state. A steady state is when the drug’s levels in the body remain consistent rather than spiking and falling.

Interestingly, this initial weight loss is no different to other weight loss treatments or the impact of diet interventions on weight loss. The real effect of semaglutide is seen beyond three months.

Semaglutide is a long-acting medication that’s started at a lower dose to reduce the number and severity of side effects as it’s built up to a higher maintenance dose.

Ozempic isn’t approved for weight loss in the UK as it’s only authorised for type 2 diabetes. Therefore, if you’re seeking to use Ozempic for weight loss, you’ll need to find alternatives like Wegovy or Saxenda.

Wegovy is the same medication as Ozempic but is available in higher doses and approved for weight loss in the UK.

How much weight can you lose in a month on Ozempic?

Research suggests Ozempic supports weight loss of around 1kg or around 1.1% of body weight after one month. After two months, it’s around 2kg or 2.2% of body weight.

However, as this is an average rate of weight loss, it’s unclear how much weight loss an individual will lose in a month on Ozempic. Some people may lose weight quickly, while others may take longer.

How much weight will I lose on Ozempic?

Research suggests that Ozempic supports average weight loss of around 6kg after 40 weeks. However, as this is an average, it’s unclear how much weight each individual will be able to lose on Ozempic.

The amount of weight people lose on Ozempic will depend on how well they respond to the medication and their ability to make positive changes to their diet and lifestyle.

Do you lose more weight on the higher doses of Ozempic?

Research suggests that higher doses of Ozempic support more weight loss. One study showed that after 30 weeks, 1 mg of Ozempic led to a weight loss of 4.5kg, compared to 3.7kg with Ozempic 0.5 mg.

However, as we’ve discussed already, everyone responds differently to medication and how much weight you lose will depend on how well you respond to the medication and the changes you’re able to make to your lifestyle.

For example, some people may lose more weight on the lower doses of Ozempic as they’re more sensitive to the drug’s effects and don’t need to increase the dosage.

Ozempic is no longer available as a weight-loss injection in the UK

Under new government regulations, healthcare providers can no longer prescribe Ozempic to patients for weight loss. It’s only approved for people living with type 2 diabetes.

However, Wegovy is now available in the UK, and research suggests it leads to more weight loss than Ozempic.

Wegovy and Ozempic are the same drugs with the active ingredient of semaglutide.

However, Wegovy is available in higher doses (up to 2.4 mg compared to 1 mg with Ozempic), and research suggests it supports an average weight loss of 17%.

Second Nature has launched a Wegovy-supported programme alongside our NHS-trusted weight-loss programme.
