Well, first, there really isn’t a “2 week plateau.” It’s just that first week results seem bigger because of the natural loss and/or balancing of water weight. So week 2 may seem “slower” but it’s pure fat loss, not fat and the expected water loss.
And by “slow” I mean, ya know, 2 to 3 times faster than a normal diet. (I always have to laugh at those who complain about losing “only” 15 pounds in 28 days, you know, since 4 pounds was once thought the be the “maximum possible” using traditional diets.)
Also, those who may have a “slow” week usually see a big jump on the next week.
Then there are scale fluctuations, incorrect weighing, lack of tape measuring, menstrual cycles, God-awful daily weighing nuttiness…
In other words, the real results are of course the FINAL results.
