Luis the fruit and veggie only diet your doctor suggested for two weeks sounds like a pretty non fun way to start on the fast track to healthy living
You're still in your twenties so you're not really in any grave danger of heart disease or neurovascular complications right now. My suggestion would be something more moderate to ease your way into a lifestyle modification. That way it's not such a startling change.
Some of the high BP, TG, LDL/VLDL, low HDL, etc can be familial but it can be modifiable as well.
I'm pretty busy working 70-80 hours a week and I manage to fit this into my schedule- initially when I wanted to drop weight I would power walk for about 45 minutes every morning for a few months. Diet modification was reducing carb intake, cutting out alcohol, increasing fiber/veg/fruit intake, and reducing meat portions. I've been at ~8 +/- oz of any type of meat a week, which usually works out to eating meat twice a week. After reaching my targeted weight I switched to run/jog/run in the mornings to just try and get my heart rate as low as possible. I also go to the gym three times a week in the evenings.
Good luck man! It's pretty cool that you're taking this seriously at a young age. My friends girlfriend's dad had a trip bypass in his low 50s and his only lifestyle change was switching to Bug Light from Budweiser...
