Ah, this is discouraging, that is for certain.
Many people (especially counselors) tend to see weight loss as a purely psychological and willpower based effort. That is far from the truth.
If you discover that you are not able to lose and keep off the desired weight, especially if you plateau and then find yourself in an overeating pattern, that pattern tends to be a little more than just emotional/willpower. Many times it is related to what is sometimes called a preservation cycle. That is where the efforts of weight loss cause a momentary spike in serotonin, and you feel great. However, as the weight loss effort becomes more long term the serotonin levels reduce, causing discouragement and a lack of will. The body cuts metabolism and increases food desire. Interestingly the loss of this valuable neurotransmitter (serotonin) can cause the body to attempt a serotonin rescue...which is where any type of food becomes a focus of desire.
How do you beat this? I will outline a plan for you here. But I would also like you to ask your family doctor if you can take 400mg of B-2 and 400mg of Magnesium Oxide each day.This is the same supplement pattern that is used for migraines, but it also helps prevent plunges in serotonin levels. You will also want to eat, a banana each day. It has a similar effect. (No kidding.) This sounds too simple, but it does help, a lot.
Now part #2:
Here is the plan to beat your body's preservation of weight after your weight loss plateaus:
For one week I want you to do nothing about weight loss. Nothing. Instead, I want you to go to bed one hour earlier for seven days. Eat as you wish, but reasonably. Day #8 I would like you to start your diet, assuming you are also doing B-2 and Magnesium the week prior. Make sure you continue to go to bed an hour early this week as well as continuing the magnesium and B-2.
What happens is your body's self preservation cycle (glucose related) begins to stabilize. The stress reaction that you have been battling will be defused by the extra sleep and the weight will come off. (Your body thinks you are starving it and spikes a food craving to help with the loss of energy. By sleeping just an hour more this cycle does not activate and your mood and weight will remain up, and drop, respectively.)
Try this...I think you will find that it is your body, not just your mind that you have been battling. Always a pleasure. Steven
