Is this an efficient diet? I'm a complete novice with dieting.

Hi everyone I'd just like to say I really appreciate this forum and I find it extremely helpful. I'm about 6 feet tall and I'm at 250lbs. I'm 18 years old and have been intensely lifting the past 4 years for football at my high school. Since I'm now done with football after a couple knee surgeries and deciding not to pursue college football I've joined a gym and I want to lose all my lineman fat and get lean for the summer. If it's possible I'd like to get as far as I can by June as I will be going to Cancun for a senior trip haha. In joining my gym I was provided with a diet plan as follows:

Meal #1 - 30g whey protein or egg beaters with one whole egg scrambled in it with 1/2 cup cream of wheat with Splenda. (It goes on to give alternatives)

Meal #2 - Approx 35g protein such as can of chicken/tuna or ready to drink protein meal replacement or protein bar.

Meal #3 Sandwich with turkey, fat free cheese, tomato, lettuce. Have an apple with natural peanut butter. (I've replaced the bread with whole grain wraps to cut back on calories)

Meal #4 - Protein and yogurt for digestion. Chicken breast, whey, tuna, turkey, etc.

Meal #5 - 1/4lb of 96% lean ground beef with lettuce, cheese, tomato (taco salad) or salmon, turkey, etc.

Meal #6 - "if you are still hungry before bed then you may eat some form of protein with healthy fat such as..." natural peanut butter spread on celery or 1/4 cup of nuts with more protein. About 30g.

It goes on to outline high days and low days. It's an average of 1800-2200 calories a day and 180-200g of protein minimum which I find difficult to do on a regular basis without going over the calorie count. This was written by the owner of the gym who was a bodybuilder and nutrition/fitness expert. You may or may not have heard of him, Brian Attebery. I do cardio an avg of 30 minutes a day with whatever machine I'm on saying I've burned 500 calories. I also workout on a regular basis. I've manipulated a couple of the meals to accommodate my likes or conveniences. I'd like to get down to 200-205lbs by June if that's possible. I started this diet out at about 260lbs and have since gotten to a little under 250lbs. Unfortunately I've been stuck at 250 for the past week and a half or so which is really frustrating. I allow myself a day where I don't consciously count calories. I don't completely gorge myself but I don't worry much about what I eat because I feel I need that one day to stay sane throughout this diet. I try not to eat past around 7 because I've heard that helps but I'm not sure. I've kind of cut down my calories to 1500/day which hasn't been much of an issue until today I felt completely exhausted and hungry after my workout so I ate about 2000 today. Is this a good diet plan? Should I switch to another more low carb focused diet? I'm not using AAS as I've learned from this forum I'm a bit too young. I've been taking a fat burner but I don't think it's doing me any good and I think I'm going to stop taking it. Any and all suggestions are greatly appreciated. If there's any advice I can get on how to get where I want quickly I'll gladly take it related to my diet or not. Thanks in advance.

Jake
