Losing weight is simple. You must burn off more than you consume. How you do that is the key and knowledge concerning that is also paramount. Lastly, discipline is the final parameter. Put them all together and you have lost weight. Sorry I was no help................
Go back to your tree trunk
The "burn off more than you consume" cliche is too simplistic and mostly an unhealthy way to approach things. Many fad diets are based on that. People gorging on grapefruit and putting carrots and such into blenders. That's no way to do it!
In 2003, and a determined FR archivist will find a lot of threads from me during that period, I lost over 100 pounds in a year. Basically it was switching to a high-fat, low-carb (sugar) diet. I also swore off anything with high fructose corn syrup and trans-fats (like margarine).
A lot of the stuff I was told to stop eating when I was fat actually helped me to take the fat off. Steak, eggs, cheese, nuts, etc. Those foods also gave my body a lot of energy so that I could adopt a more active lifestyle. I'm sure that helped too.
A few years after that, I gradually got back to old habits and the weight started coming back on rapidly. The main reason for that was that I initially banished foods from my diet that I loved like pizza and pasta. Once I started having them again, it was like an alcoholic locked in a liquor store.
I finally went back on the high-fat low-sugar diet for good, only now I allow a little bit of balance to include the occasional pizza or other "forbidden" food. Those occasional indulgences help me stay on track the rest of the time as now I don't feel like I'm always denying myself something. But some of the really bad foods out there, I don't even want to eat anymore, like packaged cookies, donuts and candy bars. Those I don't miss.
