Some drugs can speed up and slow down your metabolism, the amount of energy your body uses for a particular activity. However, it can be dangerous to make such adjustments on your own.
Many hormones contribute to metabolism
Your metabolism is controlled by many hormones as well as neurotransmitters. You can adjust your metabolic rate by increasing or decreasing the levels of these substances in your body.
Thyroid hormones have a significant effect on metabolism. The higher your thyroid hormone levels (including T4, T3 and Reverse Thyroid), the faster your metabolism. To reduce your metabolic rate, a doctor may prescribe Methimazole or Propyl-Thyracil (or PTU), which will reduce your thyroid activity and slow down your metabolism. These drugs are used in cases of hyperthyroidism.
Beta-blockers for adrenaline
Adrenaline also increases your metabolic rate, but excessive amounts can make you restless or nervous. Beta-blockers such as Propranolol can control adrenaline. These drugs do not necessarily reduce the amount of adrenaline produced by the body, but reduce the ability of adrenaline to work effectively, slowing your metabolism.
Cortisol makes you fat and fast
Cortisol is a hormone that can increase your metabolism, but also make you gain weight. While a short surge of cortisol will increase your metabolic rate and provide a lot of energy to your brain, a chronic rise in cortisol levels can make you gain weight, especially around the middle section. Aminoglutethimide can lower cortisol levels, but the drug can have serious side effects.
Do not self-medicate
The medications that can lower your metabolic rate are all prescription drugs and can have serious side effects. Reducing cortisol levels too much is especially dangerous and can even lead to death. Take these medications under the supervision of a doctor.
