Is this healthy weight loss?? -

so i am a 14 year old girl and i am 5 6 and was 146 lbs. seven weeks ago on saturday i started a diet where I basically have an apple and cup of fat free milk for breakfast. then grilled chicken salad with water for lunch. an bannanana after school and then another chicken salad for dinner with an all natural fruit popsicle afterwards. i also run a mile twice a week. this has been working pretty well and i lost 28 lbs or so. i am now 118. but then i read that i might be losing it too fast and i am scared because i wanted to lose the weight healthly.

no....I m tring this diet thanks!!!!!!..SEVEN WEEKS !!!WOW
