Firstly, there is no clear cut answer, hormones may challenge you, eating less may be sending signals to your body to hold on to as much food as possible to maintain nourishment. However, with exercise it is easy SWITCH UP YOUR WORKOUT!!
Everyone’s body is a great machine, you introduce your body to an exercise that it hasn’t done before then as a result, you get the shakes when you go down the stairs, sitting down becomes a challenge but then all that disappears, why is that? Your body is an ADAPTABLE machine. If you introduce a positive stress to it (exercise), it adapts and it is more efficient at supplying oxygen, efficient at clearing lactic acid (burning muscle pain) and connecting muscle tissue more efficiently making it feel easier. This makes you less effective as a burning machine.

Ask your Exercise Physiologist for a different exercise routine best for you to help get out of your plateau. Speak with your Dietician to get the most out of your eating plan and speak to your doctor about hormonal challenges.
