How to lose weight and stay focused on a diet? -

hello I am trying to lose weigh.t I wants to lose about 25lbs. I asked my doctor and she said I should eat between 1,100 and 1,300 calories a day. I am currently doing a rowing camp 3 times a week for two hours. what is an natural diet that is easy to follow. I have a hard time stating focused while trying to lose weight so could someone give me an easy to follow diet that I can stick with thanks.

The best way I ve found to stick with my diet, is I ve picked an outfit I m going to get as soon as I lose the weight!Every time I m tempted to stray from my diet, I imagine wearing that outfit and looking hot :) As soon as I do that It s like my determination has been reset in stone! And I m entirely dedicated again. It has really helped me :)
