A research suggests that a vegan diet can help people who are overweight or have type 2 diabetes.

According to a meta analysis, adhering to a vegan diet for three months reduced body weight and blood sugar levels. There was no effect on blood pressure or cholesterol levels.

796 people who were overweight with a body mass index of at least 25 were included in the data. At the European Congress on Obesity, the results were presented.

A rigorous assessment of the best available evidence indicates that adhering to a vegan diet for at least 12 weeks may result in clinically significant benefits.

A vegan diet is associated with a reduced calories intake due to a lower content of fat and higher content of fibre.

The second piece of research presented at the conference found that women were more likely than men to gain weight during the first year of the Covid-19 pandemic. People under the age of 45 were more likely to be overweight than older people.

The data from the Clinical Practice Research Datalink (CPRD) of more than 200,000 UK GP practices was used to cover almost 1 million adults in the UK.

Prof Thomas Yates, of the University ofLeicester, said that even modest weight gain at a population level in younger adults and women could translate into more diabetes, heart disease, cancers and other serious obesity-related health problems over the coming decades in these populations.

Toddler eat more vegetables if they are rewarded for trying them. A three-month research programme on children at nurseries in the Netherlands found that giving children rewards such as stickers or small toy crowns may help them develop a taste for healthy food.

She said the type of reward was important.
