why is the scale not moving

There are so many confusing facts about weight loss and it is very hard to know what is the truth and what is propaganda written by influential people that want to make an easy dollar.  I work with a lot of people on their fitness journey and I always urge them to measure their arms, bust, waist, hip and thighs.  When we begin a healthy eating and workout regimen, fat begins to burn and muscle grows.  This shows that you're doing a great job and are on the right track to success.  A scale can not measure how much muscle, fat, water, bone and organs weigh apart from the total  Now there are some fancy scales out there but even then there is` a 1.5% unreliability to all home scales.
Another reason I ask my client to measure before the scale is because the scale can fluctuate up to 10 pounds. Some factors like menstruation, binge eating and drinking, gas and water retention. Measurement do not fluctuate more than a 1/2 inch unless there is something truly medical going on, like IBS, food intolerance or food allergies.
A scale can't measure physical changes in your body like cardio, strength, flexibility, and agility.  It can't reflect of positive healthy changes going on like improved blood sugar or cholesterol. 
Lastly, your scale can be a total mind fuck! You work your ass off, eat right and then you are up 2 pounds.  Leaning on a scale to give you the positive reinforcement and happiness can put you at risk of giving up on your journey or worse, fill your mind with really negative self talk.  
What to do instead:
1) notice how your clothes fit
2) measurement
3)set attainable fitness goals like walking a 5k, do 100 push-up in one week or max your jump squats.  
It is easy to get hung up on the number, but celebrate your goals and keep going!
