Most people fail because they 'go on a diet' The best way is to make lasting life style changes. When I stopped drinking soda (and I wasn't drinking more than one 16 oz one most days) I lost 5 pounds in a month. (diet soda is no better, the aspartame in it is not good stuff). When I quit putting sugar in my ice tea I lost another 5 pounds. Just piling on more veggies on your plate and skipping the pasta will also help and you will be healthier for it.
Over the past three years I have gradually changed things; I very rarely, like maybe every couple months, eat fast food and then I try to go for a decent salad. I don't drink soda of any kind ever. I rarely eat candy or sweets. I don't usually cook pasta at home; if I have a starchy side it's brown rice or potatoes. I eat a LOT of veggies and fruit, especially dark leafy greens like mixed baby lettuce, kale, collards ect, I have a huge salad once a day of these (as in two or three cup fuls) with a sliced apple or other fruit, some cheese, marinated olives, sometimes other additions. The marinated olives and cheese give a nice flavor and I use no other salad dressing. I dont' eat sandwiches, biscuits, bread or other wheat products more than twice a week. That right there helped me take off about 20 pounds without trying.
It's about little baby steps here and there. Also increasing your activity level. And that is also something you can do gradually; instead of parking close to the front door, park at the far end of the parking lot and walk to the store as fast as you can. If you don't have time to go for a walk or on your break at work stand and run in place for five or ten minutes. Every little bit helps.
TOTALLY agree with the "diet" mess. Hubby and I keep telling people that know us and having fits at the weight we've lost that this is a lifestyle for us from now on. The thing is we don't feel deprived and don't stay hungry either. None of us can get over how long we can go without eating although we don't since we would lose muscle mass if we don't get our protein. But we can go for a long time without starving now and you don't have hunger bangs like before. It's totally weird!
