Some people get so daunted, when they don't see any difference initially that they give up. I would say for some people lipo isn't a bad idea - a quick fix and jumpstart, psychologically. Because a lot of this is psychological and mindset.
Once you see a difference, it's more motivation to want to keep at it. After it's really watching what you eat - healthier, and keyword:
in moderation.
As opposed to a larger body shape that never seems to go down, regardless of how much you exercise is thrown in, or how much food intake is cut. There is less or no motivation to keep going in this case, and the person might just reach the point they give up because nothing seems to make much real difference.
Another new fad that is taking on among many Asians is accupuncture dieting, which many are embracing blindly, without really thinking it out.
How it works is that the accupuncture suppresses the appetite but most people who do this treatment don't connect that they're also changing their meal plans along with the the 'instant fix' accupuncture. I believe the advocated meal plan with this method is soup, eggs and steamed chicken breast (no oil or salt) only. Once the accupuncture sessions stop, if these folk go back to their former eating habits ... they're back to square one.
I don't believe in severe dieting or deprivation. Often these only leave to cravings, and in some worse cases - bingeing. If you need that slice of cake ... go for it. Just keep that in mind, and cut down later by eating fruit instead of another larger dessert.
What is not ok is eating half the entire cake, because you went without for a whole month (and mentally the craving is just there building up)
Find some from exercise you enjoy. Don't do running or jogging just because 'you have to'.
Or make the exercise more pleasurable (favorite selection of music, shade of wall at some particular gym appeals more

. gorgeous gym instructor

... whatever). The idea is not thinking it merely as some 'must-do tedious chore' but rather something to look forward to as part of your lifestyle.
Personally I hate swimming as a form of exercise because to me it's really monotonous, and there's no music involved. Any exercise/movement for me has to with music and rhythm involved - be this in the form of dance, aerobics, or yoga. Running can only be done with music, and even this activity is really more for thinking, or building mental training and discipline (than exercise) for me
Random tips:
- go easy on carbs and dressings (of any sort. gravy included)
- it's ok to snack on 6 light meals in the day. have that inverted triangle eating chart in your mind.
beats being super busy and frantic during the day, starving ..... and then finally sitting down to pamper yourself with some 6-course heavy dinner at 8pm to de-stress!
- try to keep any food intake or snacking light after 8pm. For the extremes on the accupuncture diet - they have made this time 6pm!
- just go to bed when you feel that need to comfort yourself or de-stress with yummy food at night, and instead wake up earlier at 6pm to indulge those cravings!
- minimise storage of unhealthy tempting snacks (chips, ice-cream etc) so you have less choices to reach for at 11pm. Instead stock up on fruit yoghurt, nuts, seeds and dried fruit mixes that you can munch or eat with the yoghurt. Grain crackers are just as yummy as cookies. Harder to practise with kids and their food in the cup*** ... but worth a try.
- I have heard from one fan how Hatha Yoga (sweaty) has worked for her, and her very toned body is testimony. Of course she also backs this with great food selections (eg no sugar - substituting berries instead in her baking)
GOOD LUCK! You can do it.
