Melati and Isabel are two teenagers from Bali who started the NGO Bye Bye Plastic Bags in 2013 aged just 12 and 10. Their organisation has been instrumental in reducing the use of plastic bags in Bali. In 2018 they also launched Bali's Biggest Clean-up with 20,000 people cleaning up 65 tons of rubbish in Bali. The girls speak at environmental conferences and schools. Their advice to other teens is, find that one thing that you are passionate about, and go for it. You can read more about their Bye Bye Plastic Bags here.
For your information, it would take 134 minutes jogging to work off a large Big Mac meal or 326 minutes walking. It is the equivalent to eating nearly five Mars Bars. Scary isn't it?
Many people don't know what a healthy portion size looks like. The Australian Healthy Food Guide website has a free downloadable PDF Portion Poster which I highly recommend looking at. According to the Eat for Health website, 14-18 year old girls need the following:
Vegetables... 5 serves
Fruit... 2 serves
Grains... 7 serves
Lean meat, poultry, fish, eggs, nuts, seeds and legumes... 2 1/2 serves
Milk, yoghurt, cheese... 3 1/2 serves
Active, older or taller girls can have 0-3 extra serves of food or treats.
It would be a very useful exercise to keep a journal of what you eat and work out how many portions of each food group you eat per day.
