Live the non toxic lifestyle, you are 13 so you will gain so much from it I promise you
Elimination of EDCs, microplastics and pollutants in your life, along with a few simple health practices will go a long way
I suggest :
Elimination of drinking commercial drinks and snacks ( or atleast try your best to minimise )
Stop using harmful makeup products like lipstick or excessive use of perfumes.
Fragrances are EDCs most of the time, women actually ingest A LOT of their lipstick, it's really bad. Foundation is bad for your skin, you can use bb cream to hide imperfections. With makeup, less is more
Cut out plastic in general ( plastic materials in clothing, your room etc. ) try your best to minimise, they stunt growth and stay in your body causing hormonal issues
Fasted cardio 20 mins a day in the morning 5x a week. Life hack for boosting metabolism and fat oxidation.
Eat animal based diet with clean carbohydrate sources, minimise processed foods in general. I suggest the vertical diet.
