here's my opinion:-
PROS: L&E is one of the better options on the market - the food is normal food (not shakeS or pills or airy fairy stuff), its portion controlled and it tastes really nice (and I am quite low to mid range fussy). I think I lost 15 kgs in 4 or so months. The convenience is great, because I was working too many hours to cook and I was eating waaay too much junk food. It "forced" me to eat 3 meals and 2 snacks which I find hard. Delivered to my door, didn't have to food shop. No washing up, dinner takes 2 minutes. I was able to go "cold turkey" on my junk food and soft drink addiction because it didn't fit my plan and I had everything already planned for the day, no need to deviate
CONS: Got bored after 4 or so months, dinners are frozen, for me, I had to do the 'whole' lot otherwise I would be tempted to get other 'wrong' stuff. It was expensive (it was reasonable for what you are getting, just hard to find the money), still have to go shopping for cleaning products, personal products, household items etc, dinners are frozen, variety limited and gets boring
My biggest problem is that as soon as I stopped (despite my best intentions), I threw in a coke here and there, then a potato chip, then a meat pie and soon I was back to my old habits. I didn't change my old habits at all and therefore I put the weight back on... well, 10 kgs. Then I decided make the changes myself for good and break the old habits and I think that is the real answer.
Hope that helps a bit....
