Best advice: find some fun cardio which will be really cool to do, dancing, hiking, martial arts etc. Worst advice: all the time prohibit urself to eat junk food. One day u will just become so stressed about it, that u will start new marathon of gaining fat via eating donuts again

Best: Focus on getting enough water and protein, and move your body in a way you don’t feel like you’re being punished. Get plenty of sleep, too! Worst: just eat less….
