Diet Supplements and pills

One of the most common methods to lose weight is supplements and pills. Weight loss drugs can work in different ways, such as:

  • Reducing your appetite: which makes you eat fewer portions per day.
  • Reducing your absorption: primarily working on fat absorption to reduce calories.
  • Increasing fat metabolism: in other words, burning more calories.

Some weight loss pills can have significant adverse effects, so it’s better to stay on the safe side and consult your doctor.

Below, you’ll find the most popular pills and supplements for weight loss, as well as their possible side effects:

  • Hydroxycut: contains plant extracts and caffeine, so it is not safe for people who are sensitive to caffeine.
  • Orlistat: It inhibits fats breakdown in your digestive system, reducing its absorption. It has some side effects like oily stool, frequent bowel movements, and flatulence.
  • Raspberry ketones: It increases the level of adiponectin which is related to weight loss.
  • Glucomannan: It is a fiber extracted from elephant yam roots; it has an excellent ability to absorb water and fill your stomach.

Green coffee bean extract: it contains chlorogenic acid and caffeine, both helping in weight loss. It is not suitable for people sensitive to caffeine and may cause diarrhea


Surgery could help you lose weight in different ways:

  • Shrinking stomach size (restrictive surgery): This slows the digestive process; after the surgery, your stomach will fit only one ounce.
  • Shrinking of the stomach and removing parts of the digestive tract (Malabsorption – restricted surgery): makes it very difficult for the body to absorb calories.

Electric device implantation is a new technique that uses electrical signals to interrupt the neural signals between the brain and stomach, which prompts weight loss

Which is better for weight loss (cutting calories or increasing exercise)?

Cutting calories can make you lose weight faster and more effectively compared to increasing exercise.

However, if you’re wondering how to lose weight safely, you must do both, cutting calories and increasing exercise.

If you depend on cutting calories, you may gain the weight you lost fast after stopping your diet.
