It’s a never ending cycle.
You start to feel a bit chubby and unhappy with what you see in the mirror. So you throw away all of the junk food in your kitchen and head to the supermarket and buy nothing but lettuce and lean chicken breast.
You strictly deny yourself all donuts and forgo your morning late for green tea instead. You buy a gym membership and brand new yoga pants and start sweating it out on the treadmill every single day.
