I currently weigh 201 pounds and I'm trying to lose a chunk of weight rather quickly while eating healthy and accordingly to my exercise during the day. Days where I am "seated with some movement" I burn approximately 3300 calories and I've been keeping my intake balanced to about 1300 with lots of proteins and carbohydrates as well as a healthy balance of fats. On days where I exercise and weight lift for about 90 minutes or so I increase my intake to about 1800 or so to make up for the muscle use and cardiovascular workout. Is this a suitable range for losing a decent amount of weight rather quickly. Just to mention I am taking vitamins so I am not worried about malnutrition or anything like that.
