Do diet

Tread lightly, literally

This one's simple, obvious, and all-round good, but notoriously tough: cut the calories. It's all about eating less of those naughty, addictive, indulgent treats, whether your particular vice is chocolate, crisps, cheese or doughnuts.

So go on, cut your calories and your carbon.


Here are a few reasons to take action.

Eating junk fills your belly but empties your wallet. The cost of those cheeky snacks adds up. Save yourself, save your cash.

Brits spend a total of £3.5bn on chocolate each year.1


This is pretty obvious….

Cheese, chocolate, crisps, pastries and fizzy drinks – they may be good for the taste buds, but they're not too good for the rest of your body. They're full of bad fats and calories that will pile on around your waist.

But it's not just about putting on a few pounds - they also increase your risk of diabetes, heart disease, cancer, and strokes, amongst other nasty diseases.


packs of crisps are eaten in the UK each year.2


Everything has a carbon footprint, so excess of any kind leads to unnecessary carbon emissions. Cheese is a particularly guilty one because of all those methane-belching cows – 12 kgCO2e are released in the production of 1 kg of hard cheese.


tCO2 is the annual footprint of the UK's crisp eating addiction.

Global Goals

In September 2017, an historic agreement was signed by UN member nations agreeing to work towards 17 Global Goals for Sustainable Development by 2030, otherwise known as the SDGs.

Achieving these ambitious goals will require action from governments, businesses, NGOs, and individuals alike. We can - and must - all play our part.

By making the 'Do diet' pledge, you are contributing to the following SDG targets:

3.4: By 2030, reduce by one third premature mortality from non-communicable diseases through prevention and treatment and promote mental health and well-being

12.8: By 2030, ensure that people everywhere have the relevant information and awareness for sustainable development and lifestyles in harmony with nature

13.3: Improve education, awareness-raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning


This couldn’t be more straightforward: pick your particular vice, and then cut it out!

But remember, this DoAction is about cutting something out, not swapping it. The key is not to substitute your treats with more treats…

Success Stories

This one was really hard until I realized that cutting out crisps really improved my skin. Going to keep this one up for sure. :)

This is really clever! Got me fit too!!!!

Good for me too! Little things like this are good and although something I wanted to do for a long time I didn't have the motivation to do but will deff keep it up now!

Generally ate healthier as a result of not eating crisps:- I made more of an effort to prepare my lunch at home and not rely on fast food.

this is a great way of kicking bad habits - thanks.

Was a great eye opener - made me realise how much of the stuff I eat!
