5 Popular Weight Loss Pills and Supplements: Do They Work??

Excess weight, and the more severe form, obesity, is a worldwide epidemic as it has become a major health problem.

Usually persons become overweight if they are consuming more calories (from food) than they are burning.

The body converts the excess calories into fat which is stored as adipose tissue.

BMI is Body mass index commonly used to classify overweight and obesity. It is defined as a person’s weight in kilograms (or pounds) divided by the square of his height in meters (kg/m2).

The WHO definition:

  • overweight: a BMI greater than or equal to 25
  • obesity: a BMI greater than or equal to 30

The excess of body weight is a risk factor for many chronic diseases including Type 2 diabetes, heart diseases, cancers and endocrine illnesses.(study)

Premature death and disabilities have been associated with excess body weight.(study)

In addition to the health risk attributed to overweight, many industries (fashion, cosmetic, performing arts and sports) have placed a high emphasis on body image. The industry standard has put a lot of pressure on individuals to be “slim”.

There are various methods to deal with body fat and overweight. The rule of thumb is to burn more calories than you are taking in. The typical diet which restricts calories may yield some level of success with weight loss.

It is not unusual for the dieter to gain the weight back, often ending up with more weight than before. The aim should be to adopt a lifestyle that incorporates a healthy diet, regular physical activity, and a body fat burner.

Fat Burner and Weight Loss

A very common issue, experienced by persons on weight loss diet, is after losing some of the excess weight initially, the body resists any additional weight loss even with the best efforts.

Incorporating a fat burner gets the fat burning metabolism going again.

Fat burner supplements are mainly nutrients from herbs and foods which when taken along with a balanced diet and engaging in an exercise program, help to accelerate weight loss by increasing the body’s metabolism to burn body fat.

Some fat burner supplements have been banned as the FDA and other such analogous bodies require more research to establish the safety profile and recommended dosage. It is considered unethical to promote benefits of supplement or drugs that cannot be substantiated.

  • Eating healthy by having well-balanced meals with foods from the major food groups. It is important to consume more fruits and vegetables. Carbohydrates should be selected from those with low glycemic index. Salt, sugar, low density lipids (fats) and trans fats must be reduced.
  • Increased physical activity includes being generally more active and less sedentary. Fat burning exercises include a combination of aerobics and strength building exercises. Swimming, jogging, power walking, dancing are great aerobic exercises.

A Word of Caution

Weight Loss Pills and Supplements

You got to be careful about taking any metabolic stimulant for weight loss.

If you are pregnant it is not advisable for you to take any supplement which could result in weight loss.

This is unsafe for both the woman and her unborn baby.  Similarly, if you are breastfeeding you should not take any supplement which could pass from you in the breast milk to the baby.

It is to be noted that fat burner supplements not only promotes weight loss but may also have the effect of lowering insulin in the blood and so diabetics should discuss with their healthcare provider whether it is safe to use a fat burning supplement as part of a weight loss program.

You must be very careful about the hype surrounding fat burners as some marketers promote these supplements as the “magic supplement” to melt stubborn belly fat without dieting and exercising.

Healthy eating and increased physical activity must not be trivialized as there are significant health benefits.

In isolated cases have been reported deaths associated with the use of fat burners.

Not enough is known about these cases to determine the effect a particular fat burner had on the individual’s demise.

Bear in mind that almost all supplements and pharmaceuticals can potentially cause side effects.

This is difficult to predict due to the fact that a genetics, undiagnosed illnesses, pre-existing diseases and abuse/misuse of the supplement or drug can contribute to a bad or poor outcome.


Research all supplement and drugs before taking them.

Also, seek advice from your doctor or wellness practitioner who will assist you to determine if a fat burner is right for you.

We also recommend that once you have attained your weight loss goal that you reduce and then stop using the fat burner.

The lifestyle program will help you to maintain the healthy weight.
