How many people does it take to change a light bulb?
One, as long as the light bulb wants to be changed.
No matter what the reasoning or rationalisation, weight loss is ultimately a result of the body's energy expenditure being in excess of energy intake. There is a real limit to what one can do to exercise at a time, but there is a far bigger range in how much calories a person can ingest in a day.
As for the people who either deny being obese, or think it can be healthy while being obese:
Some challenged the "science" of BMI measurement (which was first used almost 150 years ago) and wanted to change the goalposts from BMI = 25 in spite of the fact that it is only during the last 30 years that the average cohort BMI has increased drastically within 2 generations.
There are some who think anyone suggesting that an obese person should lose weight is akin to fat shaming and bullying.
Even more now blame their obesity and life-long habitus on their inherited genes.
Some even suggest that people who are obese need some touchy-feely "approach" as if they require coaxing into actually doing something about losing weight.
At the end of the day, these "obesity-deniers" will only change when they are really determined to do so.
But at least Livingstone et al have taken away another crutch that they like to use: that their genes make it harder for them to lose weight.

There are others who think it is possible to be obese and yet "healthy". (There is no such thing: http://www.sbs.com.au/news/article/2016/09/06/fat-fit-wont-prevent-diabetes
