Public Health England launched its latest Better Health campaign last month in a bid to encourage adults across the UK to lose weight, eat more healthily and increase their level of activity.
New PHE research found that those who followed the NHS Weight Loss Plan app across a 12 week period lost 5.8kg on average.
However, this comes amid the findings that 41 per cent of adults have gained weight during lockdown, with an average of 4.1kg put on.
Meanwhile, 21 per cent reported that they had gained more than 6.3kg or one stone.
In adults aged 35 to 65 years old, the average weight gain for those who put on weight was more than 4.6kg.
Snacking and comfort eating was cited by 46 per cent of respondents as the cause of their weight gain, with 89 per cent claiming that it was important to them that they introduced healthier habits going forward.
"The pandemic has been hugely challenging for everyone and it has upended our daily routines," said public health minister Jo Churchill.
"As we build back better in the months ahead, we want to make it easier for people to adopt a healthier lifestyle that works for them.
"The brilliant Better Health campaign returns today and provides a wide range of tools – including an easy to use phone app – to support people, whether that’s losing weight, sharing healthier recipes or motivating people to be more active.
"Our new Office for Health Promotion is going to keep building on the success of this campaign, helping people to make lifestyle choices that improves both their mental and physical health."
