I cut my spending in half by paring down to essentials. For example, I no longer buy soda's, juices or milk. At about 3 to 5 dollars a day, that's a savings of roughly 90 to 150 dollars. The somewhat expensive loose teas I buy instead cost anything up to 20 dollars per 100 grams, but a 100 grams lasts months. With a collection of several teas, totaling about 500 grams I do a year. 100 dollars versus 1080 to 1800 dollars. That's money saved, while spoiling myself with delicious teas quite contentedly.
The same pattern holds true for brand products. Most can be substituted with generics if you sample. On single purchases the difference will be small, but on yearly basis they add up. Chucking useless expenses, I spend a little of what I save on premium brands that are worth it.
The same is true for your utilities. Work out what you can trim without cutting into what you actually want. Optimize your phone and ISPs. 5 to 10 dollars a piece is still 60 to 120 dollars a year. Money better spent on something you enjoy than just forfeited.
Finally, have a look at your energy consumption. Are there any hogs you could substitute or supplement with energy efficient second hand alternatives? For example, I have one computer which is on 24/7. After I purchased a used mini-computer, which uses an adapter like a laptop rather than an internal power-block like normal PC's, and switched to energy efficient lights my energy bill dropped by 30 dollars a month.
All of these things you only need to go through once, this way. After that, you'll likely find yourself once upon a boredom checking to see if you're getting flabby and adjusting. I don't fret about it, anyway.
All in all, the biggest savings, however, came from a shift in attitude which showed up all impulse purchases rather glaringly. All those things you buy without thinking or really wanting, or to avoid the 10 minutes it would take to cook for yourself.
Admittedly, I was forced to change because debts were eating up all the rest of my money. Having found the new balance, seen the debts evaporate and being left with money at the end of each month, and freedom of fretting, I can recommend it.
