I grew up fat. My dad's side of the family (4 brothers) are all morbidly obese.
When I was 18, I dropped from 265 to 225ish (at 6'1") to join the Marine Corps right after the 9/11 attacks. I struggled for 3 months at Parris Island but graduated with a very fucked up knee at 190lbs. The knee never got better and I was discharged while at School of Infantry. I was back up to 230lbs when I left the military.
Over the next year, I ballooned up to 295lbs. Decided to do something about it and in one year of anorexia, dropped to 180lbs. I was thin but unhealthy.
Within a couple years, I was back up to 280ish and hovered there for awhile until I decided to lift weights and eat right. I dropped to around 210 with 18-20% body fat in 6 months with weights only, no cardio.
I got lazy again and gained back to 275lbs. Went full Paleo and dropped back to 215 within 5 months. Stopped Paleo and since then I've reached my heaviest weight, 305lbs and I'd estimate 35-40% bodyfat.
I'm currently 33 and the yo-yo effect is going to kill me. My dad has Type 2 Diabetes and other problems associated with his weight. My blood pressure and blood sugar are currently in the perfectly healthy range but it's a matter of time before they get worse. I don't have thyroid problems or any other physiological issue to blame. My problem is purely psychological and stems from pretty much being addicted to sugar and overeating impulses.
The extra weight brings with it depression, sleep apnea, and reduced libido. Being fat makes me lazy and being lazy makes me fat... it's a vicious cycle.
The silver lining is that I've done this so many times and researched so much that I know exactly how to eat, how to train, etc. in order to do it right. I really enjoyed lifting weights and made gains quickly but I REALLY hate cardio so that's something I'm going to have to get over in order to reach my goal. My plan is as follows:
-Eat clean. Heavy on protein and healthy fats, moderate complex carbs. No white flour or simple sugars.
-Drink a shit load of water.
-Lift heavy after a couple weeks of full-body circuits to get back in the swing.
-Steady-state cardio while in a fasted state. Walking on an inclined treadmill a minimum of 45 minutes at least 5 days a week. Increase speed as the workouts get easier. Once my weight is down, I'll start incorporating more intense cardio.
-Supplements: no-carb protein shakes with BCAA's, multivitamins, and Glutamine.
Just wanted to share and if anyone's interested, I'll post progress updates.
