How does one lose 150 pounds WITHOUT surgery?

My doctor has just informed me that my body is too large and despite my efforts I'm not losing weight. His command is for me to lose 150 pounds or I will be dead before my 40th birthday. I have Diabetes, High blood pressure, sleep apnea and nuropathy and Retnothopy. I'm at a risk for a stroke, heart attack and cancer not to mention the rest of the stuff. It gotten so bad, I just completely gave up. But I have a little boy and a wife and need to go on for them.

Any suggestions.

Thanks

Eat several (5-6) small portion meals a day, you will burn calories faster and build your metabolism in a short period of time.
(eat about every 2 hours)
The first 8-10 pounds you shed is water...after that you will lose an average of 2 - 3 lbs per week until you plateau to your ideal weight.
Meal suggestions:
piece of fruit
bowl of cereal (high fiber low sugar)
string cheese, summer sausage
cottage cheese/yogurt
tuna/turkey/ham sandwich (lettuce, tomatoe)
pizza
soup
salad
raw veggies
boiled eggs
popcorn
Always eat a good dinner (small portions)...fish, meat (bake, broil, or grill)potatoes/pasta/rice, veggie...your body needs carbs, protein and vitamins to stay healthy
Low calorie sweets...ginger snaps, fig bars, 100% juice popsicles
Drink plenty of water
Drink milk (low fat) or juice/water with every meal (no soda pop)
Stay away from munchies, fried & fatty foods (no fast-food)
Never eat before going to bed.
Cardio exercise is great, but most people don't continue for an extended period, do "daily" simple exercise like walking/hiking, biking and swimming which are low impact, play games like tennis, basketball, baseball, or volleyball, they will help to lose weight, tone your body, make new friends and you'll have fun doing it.
