Medical Weight Loss Clinic Near Merrifield and Dunn Loring, VA

BeLite Medical Center is a physician-supervised weight loss practice in the City of Fairfax, about 6 miles west of Merrifield. BeLite has been treating weight loss since 1995, and our Fairfax office has served patients from Merrifield, Dunn Loring and across Northern Virginia since 1996. Your first consultation is free.

Where is BeLite in relation to Merrifield and Dunn Loring?

We are at 3923 Blenheim Blvd, Suite 61A, Fairfax, VA 22030, just south of Fairfax Circle. Free parking is available at the office park. Both Merrifield and Dunn Loring are a short run west along Route 50, and free parking is one of the things our patients from the Mosaic end mention.

Driving from Merrifield or Dunn Loring: From the Mosaic District, take Lee Highway (Route 29) or Gallows Road out to Arlington Boulevard (Route 50) and follow it west through Fairfax Circle; the office is just south of the circle on Blenheim Boulevard, at 3923 Blenheim Boulevard, Suite 61A. From Dunn Loring, Gallows Road south to Route 50 west is the same approach. This is one of the shorter drives of any community we serve — under fifteen minutes outside rush hour.

Estimated driving time: approximately 12 to 20 minutes, depending on Route 50.

By public transit: this is the best-connected locality we serve, but the connection runs the wrong way. Dunn Loring–Merrifield is on the Orange Line, and the Orange Line goes to Vienna/Fairfax–GMU, which is the closest station to our office — two stops west, about seven minutes, then a bus or a short ride from the station. For a patient without a car this is genuinely workable, which is not true of most of our pages. There is also a free weekday shuttle between the Metro station and the Mosaic District if you are starting from that end.

What does the program involve?

BeLite specializes in the pharmacotherapy of obesity: prescription medications that reduce hunger and cravings, combined with a nutrition plan, exercise guidance, and close medical supervision. Because these are serious medications, patients are seen by a medical practitioner at least every four to five weeks to monitor progress, check for side effects, and adjust treatment.

We treat people who are healthy and overweight as well as people with significant medical problems. There are no contracts. If you come for a consultation and decide not to enroll, you pay nothing.

Which medications does BeLite prescribe?

Depending on your medical history and goals, your practitioner may recommend:

• Zepbound (tirzepatide)
• Wegovy (semaglutide)
• Phentermine
• Oral GLP-1 medications: Foundayo (orforglipron) and the Wegovy pill

Selected medications can be dispensed at our on-site pharmacy, so some patients, if they choose to, can leave their appointment with their prescriptions in hand. See the full list on our medications page.

Also available at BeLite

Alongside weight management, BeLite offers Xeomin — an FDA-approved botulinum toxin type A injection that smooths frown lines, forehead lines and crow's feet. It is the same class of treatment as Botox, with comparable effectiveness and duration; BeLite chose Xeomin because its formulation contains only the active molecule, without the accessory proteins that may contribute to resistance over years of use. Treatments are given by a certified physician assistant or board-certified nurse practitioner. Results appear over three to seven days and last three to four months, with no downtime, and the consultation is free.

Who provides the care?

Appointments are with Board Certified Advanced Practice Nurse Practitioners who specialize in weight loss medications, under the supervision of our Medical Director, Richard Rothman, M.D., Ph.D. Dr. Rothman is a Board Certified Psychiatrist with a doctorate in pharmacology and extensive publications on the pharmacotherapy of obesity.

Are appointments in person or virtual?

Your first visit is in person at our Fairfax office. We believe in-person care produces better results, and it is how we start every patient. Virtual follow-up visits may be offered to stable patients when approved by our Medical Director. Read why we favor in-person care.

What do patients say?

“I love having the monthly check-ins, the convenience of the on-site pharmacy, and the friendly staff.”

Eating, Walking and Training in Merrifield and Dunn Loring

Two parts of the program happen between appointments: how you eat day to day, and how you move. Merrifield and Dunn Loring are treated together here because in practice they are one place: the Metro station carries both names, a free shuttle links it to the Mosaic District, and the postal addresses are so tangled that the same block gets filed under Fairfax, Vienna, Merrifield or Falls Church depending on who is writing. The list below is weighted toward the Mosaic, because that is where almost everything is. We have no affiliation with any of them.

Places to walk

This is the one part of the area where we have to be straight with you: it is short of walking. The Mosaic District is excellent for walking around — flat, paved, well lit, with somewhere to sit every thirty yards — but it is a street grid, not a trail. And the two nearest proper parks are thinner than their names suggest: Fairfax County’s own pages list no walking trail at all for either Dunn Loring Park or the much larger Jefferson District Park up the road, whose paths are golf course. The stream valley trails that would solve this are a few minutes further out in every direction.

So the realistic plan here is the Mosaic street grid on most days, Armistead Park when you want a measured half mile with something to hold on to, and a short drive for anything longer. One useful correction while you are planning: the Mosaic’s five garages are free for up to five hours, 6:00 AM to 2:00 AM. It is the Metro garage at Dunn Loring that charges. The on-street spaces are time-restricted and actively towed.

• Armistead Park, 8900 Arlington Blvd, Fairfax, VA 22031 — the best find in the area and almost nobody knows it: a paved half-mile path running north from Route 50 along Bear Branch, resurfaced in 2018, woods on one side and benches along the way. What makes it genuinely useful is the six outdoor exercise stations spaced along it — curl-ups, pull-ups, step-ups, balance, arm strength and stretching — which turns a short walk into something more. Honest caveats: parking near Route 50 is very limited and the way in is through a residential street, there are no restrooms, the path dead-ends in the trees so it is an out-and-back, and you will hear Route 50 at the southern end.
• Strawberry Park, Strawberry Ln, Fairfax, VA 22031 — the green in the middle of the Mosaic District, laid with artificial turf that is noticeably softer underfoot than pavement, with fountains, a great deal of seating, and restrooms and coffee within a hundred feet. There is a farmers market on Sundays. This is a place to walk laps of the surrounding blocks and sit down when you need to, rather than a park with a trail — but for someone whose knees are the limiting factor, a soft flat surface with a bench every thirty yards is worth more than a woodland mile.
• Dunn Loring Park, 2540 Gallows Rd, Dunn Loring, VA 22027 — small, surrounded by tall trees, and quieter than its position beside Gallows Road has any right to be; one visitor describes spending an hour simply strolling it. Deer are common. Be clear about what it is, though: the county lists no trails here at all — the paths people walk are informal and unmapped — parking is very limited, and the only facility is a portable toilet from April to October which reviewers do not speak well of. Treat it as a shaded twenty-minute stroll close to home. The clock hours shown online are not supported by anything the county publishes; county parkland is normally dawn to dusk.

Eating out without starting over

Your plan is built around normal food in smaller quantities, not special meals. The Mosaic District has dozens of restaurants, which makes this easier than it looks: the three below are spread across the three things that reliably work — charcoal-grilled meat with salad, a bowl of broth, and a normal restaurant where you can eat with family who are not on a plan and still order well.

• NAJA Mediterranean, 2911 District Ave, Unit 140, Fairfax, VA 22031 — Lebanese, halal, and built on charcoal: chicken shish taouk, lamb, mixed grill, branzino, and a proper fattoush. Grilled protein and a salad is the default order rather than something you have to ask for. Open 11:00 AM to 10:00 PM most days, later on Friday and Saturday, and from 10:00 AM at weekends for brunch. Worth knowing: it is cocktail-forward and gets loud in the evening, so lunch is the calmer visit.
• Viet Corner Restaurant, 2676-G Avenir Pl, Vienna, VA 22180 — at Avenir Place, steps from the Dunn Loring–Merrifield Metro, and the single best fit on this page for someone on a plan. They offer a build-your-own pho, which is portion control handed to you on a menu: broth, lean beef or chicken, herbs, and as little noodle as you care to order. The summer rolls are fresh rather than fried, and the vermicelli bowls are mostly vegetables. Open 11:00 AM to 9:00 PM, seven days. No website — ring 703-552-0225 or simply walk in.
• Open Road, 8100 Lee Hwy, Falls Church, VA 22042 — the Merrifield branch, at the Gallows Road corner; the postal address says Falls Church but this is the Merrifield one, and there are others in Tysons and Reston, so check before you set off. It is a gastropub, and we are listing it for a specific reason: it is somewhere you can take the family. Order deliberately and it works well — the Atlantic salmon, the grilled salmon salad, the brick chicken with broccolini, or the Mediterranean bowl. The burgers and ribs are the rest of the menu and they are not the point here.

Gyms and studios

Strength training protects muscle while you lose weight, which is why we raise it with every patient. The three below are deliberately different rooms: one where a coach scales a group workout to whatever you can do today, one where the machine keeps every movement off your joints, and one built specifically around strength training for older adults.

• NOVA Strong Personal Training & Fitness, 3170 Draper Dr, Unit 9, Fairfax, VA 22031 — one-to-one and small-group training, with strength training for older adults named as a specialty and the ONERO programme, which is a resistance protocol developed specifically for low bone density, run as a dedicated offering. The reviews read like our own patients talking: a woman in her seventies working on bone density who says each exercise is demonstrated before she starts; someone who had never been a gym person and now goes twice a week; someone who found other gyms intimidating because everyone else already knew what they were doing. The first session is free. Open 6:00 AM to 8:00 PM Monday to Thursday, to 6:00 PM Friday, 8:00 AM to 2:00 PM Saturday. 703-552-5464. One honest note on geography: Draper Drive is at Fairfax Circle rather than in Merrifield, which makes it the closest of everything on this page to our office but not the nearest to your house.
• [solidcore] Mosaic, 2985 District Ave, Suite 150, Fairfax, VA 22031 — fifty minutes of slow, controlled resistance work on a reformer. It is hard, and it is also entirely low-impact — no jumping, nothing landing through a knee or a hip — which is the property that matters if impact is what has stopped you before. Book the class called Starter50, not a regular class: it includes the machine explanation, programmed rest between muscle groups and proper demonstrations. Regulars say this studio feels smaller and less intimidating than the larger ones nearby, and one older client singles out the focus on strength and balance as what matters with age. New-client packages exist but are not priced online; ring 571-350-8333.
• Mosaic Fitness Center, 2929 Eskridge Rd, Suite F, Fairfax, VA 22031 — a veteran-owned CrossFit-affiliated gym, which would normally rule it out for this page. It is here because of three specific things it offers: an Entry Level Bootcamp for people brand new to exercise or coming back to it, running every weekday; recovery and injury-prevention sessions you can buy without a membership; and dedicated corrective exercise for people worried about getting hurt. A member who started at forty-eight with a desk job and no background says so plainly, and another describes the coaches tailoring corrective work around her injuries. Check the hours before you plan around it: it runs 5:00 to 9:00 AM and 4:00 to 7:00 PM on weekdays with nothing in the middle of the day, Saturday mornings only, and closed Sunday. 703-278-2746.
