Weight Management

weight loss

Many questions – and myths – surround the topic of weight loss. Fad diets may help drop the numbers on the weighing scale quickly but that’s just for the short term. Is there a way to achieve sustainable weight loss without damaging our health and mental well-being?

Halley’s weight loss

Our weight management programmes are designed based on Dr. Terence Tan’s philosophy that weight loss need not and should not be a painful and lonely journey. Our treatment strategy comprises three areas to take weight loss head-on in a safe yet effective and sustainable manner.

Doctor consultation

Let the doctor plan a pathway to weight loss success.

Weight loss medications

Let our doctors prescribe weight loss medications that are safe, effective, and approved by health authorities.

Meal replacements

Weight loss shakes help us maintain a low-calorie yet nutritious diet.

It is our patients’ courage to pursue weight loss that motivates us. Dr. Terence Tan explains in this Youtube video.


During consultation, our doctor will design a weight loss programme based on your key body statistics, preferences, and lifestyle. It has to be safe but also practical to be effective.

To help you stay on track with your weight loss plan, the doctor may also prescribe weight loss medications and nutritional supplements approved by the US Food and Drug Administration (US FDA) and fat reduction therapies like CoolSculpting, body firming, or muscle toning treatments to further contour your physique.

Weight loss

Eating healthily and exercising regularly are the basics of an effective weight loss strategy. But weight loss is a mental exercise as much as a physical one, and we need all the help we can get to keep the weight down.

Prescription weight loss medications can be used in tandem with dieting and exercise strategies to achieve the desired weight loss. However, they have to be taken under the watchful eye of a doctor.


Calorie-reduced diets are the cornerstone of the modern weight loss approach. This low-calorie diet can come in the form of a meal replacement shake, which is not just low in calories, but portable and easy to make.


Meal replacement shakes like Optifast by Nestlé help us lose weight while ensuring that we get all the essential nutrients to stay healthy. It eliminates our need to weigh, measure, or cook your food. By replacing a meal or two with a shake, one can be sure of the consumption of the exact right amount of energy and nutrients based on your weight loss goals. It is suitable for those who do not have the time, ability, or who do not want to go through the hassle of preparing weight loss-friendly meals. 

Used under the guidance of a healthcare practitioner and combined with lifestyle modifications, Optifast is clinically-proven to help overweight people lose excess weight, improve health, and lower weight-related health risks. It is available in a variety of flavours like chocolate, strawberry, and vanilla.
