Weight Loss

Physician-Guided Medical Weight Management and Body Contouring

At her Upper East Side practice, board-certified dermatologist Dr. Marie Hayag provides comprehensive, physician-supervised medical weight loss and non-surgical body contouring. Weight management is complex and often influenced by hormonal, metabolic, and lifestyle factors. At Marie Hayag, MD, personalized treatment plans combine evidence-based prescription therapies with advanced body sculpting technologies to support sustainable fat reduction, improved muscle tone, and long-term metabolic health.

A Brief Overview of Medical Weight Loss

Weight gain and difficulty losing weight may present as:

Increased body fat accumulation
Stubborn fat resistant to diet and exercise
Slowed metabolism
Reduced muscle tone
Fatigue or low energy

Because sustainable weight loss requires more than short-term dieting, professional evaluation ensures a structured, medically appropriate approach tailored to each patient’s health profile and goals. Weight gain may reflect underlying metabolic or hormonal factors, so early medical evaluation can significantly improve long-term outcomes and sustainability.

What Causes Weight Gain and Difficulty Losing Weight?

Weight changes may result from:

Hormonal imbalances
Insulin resistance
Slowed metabolism
Aging-related muscle loss
Stress
Genetics
Lifestyle factors

A comprehensive physician-led evaluation helps identify underlying contributors and ensures treatment is both medically appropriate and tailored to each patient’s physiology.

Weight Loss Treatment Options

Comprehensive Medical Management with GLP-1 Medications

Definition:

GLP-1–based medications are FDA-approved prescription therapies that regulate appetite, improve insulin sensitivity, and support metabolic function under careful physician supervision.

GLP-1 therapy helps reduce appetite, support consistent weight loss, improve metabolic regulation, and assist patients in achieving sustainable fat reduction when combined with lifestyle modifications.

Who it’s ideal for:

Ideal for patients struggling with obesity, metabolic resistance, or difficulty achieving weight loss through lifestyle changes alone.

EmSculpt

Definition:

EmSculpt is a non-invasive body contouring treatment that uses high-intensity focused electromagnetic energy to stimulate supramaximal muscle contractions.

EmSculpt helps build muscle tone while reducing fat in targeted areas, improving body composition and definition.

Who it’s ideal for:

Ideal for patients seeking enhanced muscle tone and fat reduction in areas such as the abdomen or buttocks.

CoolSculpting

Definition:

CoolSculpting is an FDA-cleared, non-surgical fat reduction treatment that uses controlled cooling technology to target and eliminate stubborn fat cells.

CoolSculpting helps reduce localized fat deposits that are resistant to diet and exercise, improving contour and body shape.

Who it’s ideal for:

Ideal for patients near their goal weight who want targeted fat reduction without surgery.

Vitamin B12 Injections

Definition:

Vitamin B12 injections are physician-administered supplements that support energy production and metabolic function.

What it helps with:

B12 injections help improve energy levels, support metabolic processes, and complement a structured weight management plan.

Who it’s ideal for:

Am I a Good Candidate for Medical Weight Loss?

You may be a good candidate if you:

Struggle with persistent weight gain
Have difficulty losing weight despite lifestyle efforts
Experience metabolic slowdowns
Want physician-guided, non-surgical options
Seek long-term, structured weight management

Eligibility is determined based on medical history, metabolic profile, and individualized health goals rather than weight alone. A consultation with Dr. Hayag includes a medical history review, metabolic assessment, and discussion of personalized goals.

What to Expect During Treatment & Recovery

Medical weight loss programs are customized and may include prescription therapy, body contouring sessions, and metabolic support. Treatment timelines and response vary based on individual metabolism, adherence, and selected therapies.

GLP-1 medications are administered under medical supervision
EmSculpt and CoolSculpting are performed in-office with minimal downtime
B12 injections are quick, in-office treatments

Weight reduction occurs gradually and safely under physician monitoring. Body contouring improvements develop over several weeks as fat reduction and muscle tone improve.

Cost of Weight Loss Treatment

The cost of medical weight loss depends on:

The selected treatment plan
Prescription therapy requirements
Number of body contouring sessions
Duration of treatment

During your consultation at Marie Hayag, MD, a detailed, personalized treatment plan and transparent cost estimate will be provided.
