Why does my energy level crash at the end of the day?

Asked by JeffHP (92 points ) November 16th, 2010

My girlfriend started eating better about a week ago, cutting out cafe mochas in the morning. She is finding herself crashing around 8–9 pm. How long will this continue? Is it just a reaction to much less caffeine? She has green tea in the a.m. instead of coffee now.

She should recover in a couple more weeks at most. Her body will adjust.

Changing what you eat does not necessarily mean you are eating better. I drink hot chocolate all day long but I don’t crash. This might be because I eat yogurt and fruit for breakfast, a salad for lunch…

The food you eat is diverting your blood for the digestion process. While natural, depending on what you eat, this process can increase your energy levels, or it can cause sluggishness.

In particular, sugary foods increase the blood sugar levels more than normal, causing your pancreas to release insulin. In turn, the insulin triggers tryptophan, which gets converted into serotonin in your brain, a neurotransmitter that makes you feel sleepy.

Once she gets past the caffeine withdrawls she should be back to normal in a couple weeks.

Cutting out mochas is not necessarily eating better. Energy for the body come from the calories and quality and quantity of these calories. She may need to “balance” the amounts and frequency of her food to provide a more steady supply of this “fuel” she needs to keep her motor running.
