What to do if the scale stops moving

PANIC!!! QUICK CUT OUT ALL THE FOOD AN GO ON A 'JUICE DETOX'!!!

No don't be an idiot!

The scale reflect your relationship to gravity at that second in time, they will fluctuate and the more you stress about it the slower they will be lower. 

Speaking of which, stress is a factor that can help get the scales moving and slow them down, if you have a crap day at work, or something is happening that is stressing you out in life you retain more water which means the scales wont move as quick, it also means that you could pick poor food choices to make yourself feel better, called comfort eating, this could actually cause you to gain weight/fat rather than lose weight, so if the scale doesn't move don't worry just, be consistent and you will help to get it going again.

Another thing that affects the scales are carbs/salt both of these cause water retention in the muscles so if you have a very high meal the day or 2 days before the weigh in you might notice your weight actually go up, thats because of the high salt/carb meal.

So those are the things that can affect the scales now to get them moving again, ask yourself 4 questions -
How was my sleep this week? 
Was I consistent with my diet?
Was I as active this week?
Have I had a high salt/carb meal recently? 

if you have been consistent with your diet and exercise, you haven't had a high carb/salt meal, your sleep has been good, then wait a week or 2.

if it still doesn't move then reassess your diet if you aren't sure how to that, send me an email an I'll be happy to help.

The fixes to your diet may come from cutting your calorie to create that calorie deficit,or changing your macro amount to make it easier to stick to the calories in the deficit, more or add an extra session.
