The whole concept of grapefruit for weight loss is nothing new. It has been around since the early 1900s.

The diet, which has several variations, lasts 10-12 days and claims to help you lose as much as 10 pounds. But before you try to consume grapefruit or grapefruit essential oil for weight loss, let’s dig into some more information.

Is Grapefruit Good for Dieting at All?

Grapefruit Benefits

If you’re wondering “How does grapefruit help you lose weight?” As per studies say that including grapefruit in diet can help reduce a few extra kilos of your weight. The particular enzyme called AMP-activated protein kinase (AMPK) gets activated by a natural ingredient in grapefruit known as nootkatone.

When that specific enzyme (AMPK) gets activated, it enhances the body’s metabolic rate by encouraging the energy-producing processes in the system. Improved metabolism can help in weight loss. Usually, this enzyme gets automatically activated during a cardio exercise and assists the muscles in utilizing stored sugar and fat for energy.

Harmful Effects of Grapefruit

By characteristics, grapefruit is suitable for everyone as it is a natural source of vitamin C(1). However, there might be a few exceptional cases where it doesn’t suit.

  • Mixing grapefruit with certain medications could lead to severe health complications, such as increased blood levels.
  • Other than vitamin C, there are a lot of other substances in citrus fruits like grapefruits, which make them harmful when taken with certain medicines.

Why Is Grapefruit Bad, Again?

When eaten, a special chemical ingredient required to break down various drugs in the body in the grapefruit finds its way to the intestine. Now, access of this specific chemical could increase your blood levels drastically. As a result, the drug can become more powerful.

A similar impact has been found in almost all calcium channel blockers, which are utilized to control blood pressure. A few of them include Nisocor, Plendil, and Procardia. The result has also been found in Sandimmune, a medication that suppresses the immune system and tranquilizers, such as Xanax and Valium.

Separate types of medicines which may possibly interact with grapefruit include antihistamines, painkillers, steroids, and medications for asthma. Nevertheless, it does not mean there would be a side effect with every prescription or drug in these categories. Some might and some might not.
