Fat men and thin women are the typical owners of London’s millionaire homes.

Super-rich women who live in properties worth more than £25million stay in shape by using the swimming pools, fitness equipment and saunas in their mansions.

Research by London estate agency Rokstone showed it paid off with 90% of them have a healthy BMI (body mass index) rating and lifestyle.

In comparison only 10% of male occupants were considered healthy by NHS standards, with rich men tending to spend long hours stressed in the office rather than in the gym exercising.

Step away from the rarified palaces of wealth and generally the more expensive your home, the fitter and healthier you are likely to be.

While lower value homes, without swanky on-site gyms, usually have more overweight and unhealthy occupants.

In properties priced below £1million, 40% of households have a healthy BMI rating and lifestyle, in those worth £1million to £2million 55% of people have a healthy BMI and in the £2 million to £10million price bracket 65% of households are healthy.

Rokstone managing director Becky Fatemi said: “There is a strong correlation between London household fitness and wealth.”

Overall women were found to be winning in Central London as, regardless of property value, they are much more health and fitness conscious than men.

Becky said they found it easier to juggle the constant battle to balance their busy working lives and leisure time. “Even if they work in high level jobs, we find that our female clients will simply get up earlier and time-manage in order to create space in their diaries for health and wellbeing activities,” she said.

“In addition, they tend to be more health and diet conscious with personal trainers and nutritionists.”

Rokstone analysed the fitness habits and buying patterns of 6,000 people including young celebrities (5%), London/City executives (55%) and overseas buyers (40%)

It also estimated their BMIs, which is calculated by dividing a person’s weight in kilograms by the square of their height in metres. A result of 18.5 to 24.9 is categorised healthy by the NHS. The findings were compared against NHS figures and the February 2016 Government report into household fitness which found just over half of Londoners have a healthy BMI, compared to 43% for the rest of the UK.

The heathiest areas were Regent’s Park (65% healthy BMI), Fitzrovia (60%) and Kensington & Chelsea (55%) and the unhealthiest Hackney and Southwark.
