"I tried diet X for a week but I didn't lose any weight!  Diets don't work!" I have heard this bullshit EVERY fucking day this week thanks to being on travel doing interviews for clinical trials.  Last night I put together a chart on my own weight for these fatties. A week ago I weighed 152.2lbs.  The next day I weighed 154.6lbs, the day after I weighed 155lbs.  On Monday I weighed 153.4lbs.  Yesterday I weighed 154.6lbs.  Today I weighed 151.2 lbs. Dear fatties, what happened?  Most I've shown this to said "You ate more last week then dieted and exercised this week, but diets don't work for me." NO you fucking idiots.  NOTHING HAPPENED.  I had the same routine, diet, and exercise.  I'm running 10k every day, and eating 2200kcal every day.  I did not gain, nor lose weight.  This is natural variation in body weight due to differences in instantaneous hydration, digestive state, and other transient factors!!!  My morning post evacuation weight has been stable in the 150lb - 155lb range for years!  During a given day I can weigh between 150 and 160lbs depending on when I weigh myself. It's just fucking noise!  You can lose about 2lbs a week healthily.  If my natural weight has a 5-10lb variance throughout the day, you won't be able to see weight loss on the scale with confidence unless: Neither of which fat asses do because they require time, effort, commitment, and will power. Diets don't fail.  YOU fail.
