Arnold Schwarzenegger has a great quote here (paraphrased): "If the President of the United States has time to workout, _you_ have time to workout."
Some people think freezing food destroys its quality, but I think that the evidence for that is weak and fails to regard the loss of quality that comes from keeping things in the fridge for another day.
When I stopped eating ready meals I lost a kilo in a week, I believe (believe) that happened largely because I dropped so much salt out of my diet and therefore I was retaining much less water.
Buy things fresh, make meals and freeze them. This will allow you to cook good things quickly in the evening. Spend an afternoon and make a chicken casserole, a beef stew, a lasagne, a cottage pie and a fish pie. Freeze in portions (aim for five from each) and you have weeks of quick, nutritious and delicious food that means that you will not be stuffing yourself with rubbish.
But also buy a steamer and make sure that you have a large portion of steamed green veg every day. You're five a day can have one orange juice and a couple of bits of fruit, but a decent wodge of green is really important. Tender stem broccoli, greens, cabbage, peas, beans... all take about 30 seconds to prepare and 3-4 minutes to stem (tip: only put a mugful of water in the steamer, it will boil fast and then cook the greens just as well as 4 inches would).
http://wholehealthsource.blogspot.com/2011/08/seed-oils-and-... gets into a little of the picture.
Personally I take a flaxseed oil supplement (for high omega-3), often fry in olive oil, and try to minimize seed oils otherwise. (I don't try that hard, but my intake has changed since learning about this.)
Salt intake I wouldn't worry about unless you have a specific issue making it a problem.

1) 7-8 hours sleep per night.
2) 1 hour of exercise per day (some days cardio, other days weights(focus on compounds; squat, deadlift, bench press, shoulder press, pullups, rows))
(for people thinking "I'm too busy to spend an hour of my day exercising". I think the productivity increase of clearing your head doing this exercise more than makes up for the hour it takes.)
3) balanced diet consisting of fresh natural foods. (fruit, veg, meat, fish etc. not frozen meals, microwave food where your not quite sure what's in it)
Found I've lost weight, cardiovascular endurance has increased, I'm stronger and just feel a lot better.
So my advice would be try and do all the above before taking any drugs that aren't very well researched and could cause long term issues.
