If there is one lesson I can tell you all and that is do not allow the scale to be your measure of how well you are doing on your journey. Because our bodies are well over 50% water, anything from the types of foods we eat, the exercise that we do, to our hydration, hormones, even our bathroom habits can affect the number on the scale.
When it goes up, it does not mean you did or are doing anything wrong. Remember all changes within the body must begin at the cellular level so it's going to take time for them to show up on the scale.
Keep accountable to your nutrition tracking as study after study show that those who honestly track their food intake lose twice as much weight as those who don't. Keep on exercising and drinking your water. And stay focused...the changes are happening and in the best way possible--
And remember weight loss itself is not a goal, but the results of meeting goals-- (such as eating 5-9 servings of fruits and veggies per day, getting in 7-8 hours of sleep, drinking water in place of soda, walking 10,000 steps daily, etc)
Hang in there!
