He said, as a nation, we are "significantly fatter" than most of the rest of Europe.
Plans are afoot for greater use of gastric bands, while the government is also working on issuing diet advice.
Family exercise plans could also form part of the country's wider fitness plan.
We feel strongly about playing our part in tackling childhood obesity.
Now Cadbury has pledged to help tackle the obesity crisis from a young age by reducing the size of some of our childhood favourites.
Parent company Mondelez has announced it will reduce the calories in three of its bars over the "next few months".
The bars affected
Chomp, Curly Wurly and Fudge will undergo something of a makeover and their calorie content will be less than 100 calories per bar.
The brand said the recipes will stay the same but it has not said how much the bars will shrink by in terms of size.
It's not known if prices will also reduce in line with the change.
Currently, a Curly Wurly weighs 26g and has 118 calories.
A Chomp weighs 23.5g and has 110 calories.
The Fudge bar weighs 25.5g and has 114 calories.
The changes will apply to both single bars and those in a multipack.
The move forms part of a commitment by Mondelez to introduce a 100 calorie cap on all of its products that are commonly bought for children.
Freddo, Buttons, Mini Fingers, Cadbury Animals and the Little Bar are already under 100 calories each.
The bars will get a new pack design, with "a striking flash" that will signal the calorie change.
Mondelez MD Louise Stigant told The Grocer that limiting portions was "the right approach in terms of helping parents control calories when wanting to treat their children".
She added: "We feel strongly about playing our part in tackling childhood obesity and are focusing on the areas where we can make the greatest impact."
