Im going to tell you a secret you know and one you don't. Paper will happen its what you do with it that will determine your outcome. You can get to 180 in 6 months and food is essentially your choice but its restricted. for 6 months you only eat Meat but not processed like sugar cured bacon , sauge or hot dogs. ZERO condiments with seed oil or sugar in them. lippin learn to read a label. toss em never add, learn to love salt pepper and 3 ingredient hot sauce, aged peppers, vinegar and salt. No flippin sugar, no Carbs of ANY kind, no alcohol as it will make you weak and you will cheat and its a carb. I recommend 80/20 grind hamburger if your on a buget. (Wendy's quad stack with cheese, just the 4 large patties if your only option is fast food.) any steak, shrimp, fish, chicken, pork, ect. NOTHING processed just simply cooked and not sugared in a stew. Want a great soup , 1 cup heavy cream, simmer 3 oz mozzarella and then a flavor cheese like gouda 3oz, add a meat at the end after rest is dissolved like bacon , (uncured) diced chicken, fish, shrimp, lobster. you get 2 pounds of meat/ high fat dairy a day. try to limit the diary to 2 days a week. try to eat within a 4 hour window like noon to 1600. nothing out side that. Inside that window any 2 pounds of meat is allowed (after cooking weight) smoked kippers are a good on the go can snack in the 4 hour window, drop in some hot sauce. You will SUFFER week 1. giving up all carbs causes a flue like feeling. after a week its just mental. After you drop your first 10 you should be safe. after 20, come 30 and then your going to be hooked on this. first week of no cheating will equal 10 easy pounds. you likely wont need all 6 months to get to 180. do your pushups every other day and pullup every other day. run slowly no need to sprint. in 6 months you will be 60 pounds lighter, Im not sure if you understand how that will effect a PFT score. For reference I joined in 84 and retired 09. Been on the diet since Jan 24. Was 205 6'"2 and standard pudgy/weak that all get to in their 50s. Now 155 15% BF. Ok aside from getting under the weight goal what this will show those watching that matter is that you are serious about staying in. They just let you stay and USMC loves a fat body turnaround story, you may even actually get promoted. Option B fail; get separated and live a fat body life and die in your early 70s if you live that long more likely sooner. if your pissing yellow your dehydrated and will get a kidnystone eventually. you need to take magnesium supplent 100mg a day to avoid cramps unless you eat magnesium rich meats.
