I'm recommending what Im doing, since it worked on me so well.
Get your hands on FMS 45 Minute Fat Burning Workout video. Comes
from here or else you can download it or borrow it from fiend.
You do that workout with 30 lb dumbells, and then once you are compfortable with those, you go on to 40 lb, and then 50 lb, and so on. You will also need a set adjustable 20 lb each dumbbells for lateral and frontal raises... It's ok if it takes you two hours to do it, as long as this workout is followed consistentely, every other day.
Then you need to wake up each day and run. You can run for 5 minutes or so, until you get tired. Then you can walk, so that the whole thing takes you 20 minutes or more. 20 minutes is all you need, really. At first it will be hard, but after a month or so it will be easy, and the only limition will be in your head. You can try increasing running time when you realize where the limit is coming from. This is best done right after sleep and before shower, like at 5 or 6 pm, on hungry stomatch, and outside.
Then you have to follow a diet. General rule is to eat things that have a good protein to fat ratio. Such as tuna, 23g protein, and 1.5g fat, that's good. Also deli meat, 16g protein, 4g fat, that's good. If there is 3 parts protein, and 1 part fat it's good. Try to make each meal to be around 350 calories or less. Say NO to foods that don't have Nutrition Fact Labels on them, such as what is cooked at home. Your mommy home food is what got you fat, fat a55.
Take a piece of paper and count your calories. Eat 1000 calories a day, give or take 400. This will get flame on this forum. But I have results to prove that it works for me for loosing fat without loosing muscle. Read bellow.
You can apply same body building techniques as others recommend, such as 1 serving of whey before work out and 2 serving after it (you still count calories). Drinking 8 cups of green tea a day, works.
Now, on this plan I lost 8 % body fat in two months. Muscle was not lost, as I am able to lift more, look bigger, and registered muscle mass change on my scale.
For food I'm using SmartOnes, LeanCuisine, those that are around 290 per serving. That and tuna, and sardines, and what ever else that has good ratio of fat and protein.
To notice results it takes around 20 days of working out. It's not hard at all. The most important thing is cardio, and diet, weights are to build muscle and keep metabolism up. Don't take supplements, as I noticed I stop loosing weight when I took some fat burning supplements.
Make a log of your weight every morning, so that you know if what you doing is working. If you not loosing weight after running and working out, decrease your calorie intake.
One more thing. NO food past 5 PM, unless you taking whey after workout. No more than 4 beers in the evening, once a week OK, or quarter bottle gin or vodka is fine also. 8 hours of sleep, otherwise it catches with you fast and slacking begins. If you running at 5, then sleep at 9.
