09/12/2025

Weight loss supplements and medications are among the most common tools people reach for when trying to slim down faster. Two of the most well-known categories are Adipex (phentermine) and various fat burners.

While both aim to support weight reduction, their mechanisms and strength are completely different.

1. What is Adipex?

Adipex (phentermine) is a prescription medication for weight loss.

Its main effects:

✔️ Strong appetite suppression

It affects appetite-regulating centers in the brain, reducing hunger and cravings.

✔️ Increased energy and alertness

It acts like a strong stimulant, raising energy levels and metabolic activity.

How fast does it work?

Most people experience rapid weight loss because they eat significantly less.

2. What are fat burners?

Fat burners are dietary supplements designed to support metabolic rate and energy expenditure.

Common ingredients:

caffeine
green tea extract / EGCG
L-carnitine
synephrine
capsaicin
CLA
black pepper extract (piperine)

Their effects:

✔️ slight to moderate metabolic boost
✔️ improved workout performance
✔️ reduced fatigue
✔️ mild appetite control (depending on stimulants)
