You should write a book and make millions telling everyone how easy it is. Be sure to send those women a free copy and a thank you. LOL.
It's not easy, that's the problem. You can't expect to loose weight without changing your lifestyle, and most people don't want to change their lifestyle. They just want to loose weight fast without having to give up the things they like. That's why there are so many books about the subject that are all bull****. While the rules can be written in 4 lines:
- eat healthy, that means giving up a lot of stuff you like to eat completely (if you don't have selfcontrol) or only eat them in small portions
- sport, you don't have to be an outstanding athlete, but at least use your bike to go to work or if you go shopping. You don't need an expensive fitness subscription to go running twice or three times a week
- drink water instead of whatever you are drinking that is filled with sugars. Smoothies and fruit drinks are most of the times worse than soft drinks
- most importantly: even if you do all of the above, don't expect to be thin in a matter of weeks, it will take a long long time before you are in shape again and you'll probably give up halfway.
Just following those three rules would solve the problem for 99% (yes that number is completely made up) of the fatties out there. The rest have some kind of medical condition and need specific care/diets.
