Hi im a 18 year old male. im about 6`3-6`4 .weigh about 260 pounds. Im going to start working out. Going to go on a 1500 calorie diet. Because i want to lose atleast 2 pounds a week. For about 2 months. I want to lose about 20-25 lbs . But iam also going to start work. And i work for a landscaping company so i mow lawns, trimming and all that. For about 9-10 hours a day Monday through Friday. Is that alot of calories im losing? With work and going to the gym? What should i do?
