Will losing weight help pass a drug test?

Yes, losing weight will help to pass a drug test. BUT this will work only for a urine drug test for marijuana and must be done correctly.

We’ll explain how to lose weight correctly to increase your chances of passing the drug test.

How losing weight helps to pass a drug test

THC, the main active component of marijuana, is highly fat-soluble. Body fat tissues take up about 70% of the THC in the blood.

THC is then continuously released back into the blood. That’s why you can test positive for a long time.

If you want to get all traces of marijuana out of your system, you need to break down all those fat cells containing THC.

When you lose weight, your body uses body fat as a “fuel” and burns fat cells. THC is then released into the blood and excreted from the body.

That’s why losing weight helps detox from THC and pass a drug test.

How to lose weight before a drug test correctly

If you want to lose weight before a drug test, you must consider that it’s a complex process. If you just stop eating, your body will enter the “stress” mode and use your muscles as an energy source. It will keep fat cells as a reserve.

So, in this case, your body will not remove THC from the body.

To make your body use burn fat cells, you should calculate the Daily calorie needs according to your activity level. Then you should consume 500 calories less than that amount.

This will make you lose about 1 pound of body fat per week.

You should also consume about 0.024 oz of protein per pound of body weight. It will help your body prevent using muscles as an energy source and use body fat instead.

If you will also add intermittent fasting, you will get THC out of your system even faster. We explained the method here: Does Fasting Help detox THC?
