I've been reviewing the 4 day diet for my fatloss workouts site. It is very similar to carb cycling and promises 7+ pounds of fat loss in 4 days. I don't know what it is about quick weight loss and rapid fatloss that is so appealing to most people (even me). I guess if it really is possible to lose 7+ pounds of fat in under a week then why wait 8-12 weeks for the same results.
The most fat I've ever lost was 5% bodyfat in just over two weeks which showed up on the scale as a 4 lb loss. I have had clients who lost 15 pounds in just over 2 weeks but much of it was false weight (either way it motivated them to stick with good eating and exercise and keep losing).
The truth is the more overweight and out of shape you are the easier it is to achieve quick weight loss or rapid fat loss. The leaner and fitter you are the longer it takes and the harder it gets to lose fat. The main reason for this is your body doesn't like being lean. It would rather retain a healthy level of bodyfat in case of famine (your body only cares about survival).
The reason I'm writing about this today is that it's very tempting to ditch a plan that is giving you consistent but slow results for the promise of fast and easy weight loss or rapid fat loss but the reality is that weight loss and fat loss takes time, patience, commitment, will power, and perdiodization for life not just for 1 week or 1 month or 12 weeks.
There ARE ways you can speed up your weight loss or fat loss results. Check out my article Fat Loss Secret Tips
