When the scale has stopped moving, look for non-scale victories to keep you motivated. Using things like an In Body scanner can show you potential increases in muscle or water where the scale has shown a plateau in your weight loss. This can also help you to see more progress while the scale may not change but your body’s morphology or waist size does.
This is also a great time to assess your dietary intake and see if changes need to be made to stricter types of food or the addition of mild to moderate exercise.
Small increases in your daily carb intake can alleviate plateaus that come from too restrictive of carbs resulting in a slow down in metabolism as well.
