Back in October, we sat down with Dr. Daniel DeFeo of Osteopathic Family Medicine of Northern N.J, were he answered some popular questions from our readers.
On Weight Loss Basics
Q: The number one question we are hearing: "How do I lose weight?" What do you tell patients?
A: The basics of this have not changed. Eating healthier and staying active are still the foundation to healthy weight. Regarding healthy eating, that includes having a diet full of fibrous and nutrient dense foods while monitoring portion control. Staying active can include, but not be limited to, regular walks around the office or neighborhood, recreational sports and activities, and intense training at the gym.
On GLP-1 Medications
Q: We can't talk about weight loss in 2025 without mentioning GLP-1 medications. Can you share your thoughts on these medications — are they game-changers or just another tool?
A: It's a little bit of both, to be honest. These medications essentially decrease appetite, thus reducing calorie intake. Less calories in usually means weight loss. But patients are more successful on these medications when they eat healthily and exercise. I counsel all my patients taking these medications about the importance of improving diet and activity while taking the medication. It's even more important to develop these habits for when they stop the medication, to prevent rebound weight gain.
Q: Many patients ask: "Do I have to be on these medications forever and are they safe?" What do you say?
A: One thing I make clear to all my patients is that I am only offering my recommendations. No one must take anything they do not want to. I can provide medications to improve their chances of success. When someone is taking these medications for weight loss, I have no hesitation in discontinuing them when they achieve their goal weight. This class of medication has now been on the market for 20 years with the release of Byetta in 2005, as a diabetes treatment. They are generally safe and well tolerated, and for people with diabetes they tend to stay on them for years, to control their blood sugar levels. Unfortunately, there have been some negative side effects regarding visual loss with one of these medications, and more research needs to be done.
On Managing Conditions Without Medication
Q: Another top question we hear is: "Can I manage my cholesterol, blood sugar, or blood pressure without medication?" How realistic is that for most patients?
A: Yes, and I am going to sound like I am repeating myself here. Eating nutritiously, staying active and maintaining a healthy weight are the best things you can do for yourself to manage chronic conditions without medication. There are certain over the counter supplements that can be of benefit. However, these do come with their own risks as they are not studied like pharmaceuticals nor are they always tested for quality or adulterants.
Q: What's one thing you'd tell a patient who wants to avoid medication but is genetically predisposed?
A: I usually counsel my patients that we can try diet and lifestyle modification, weight loss, and supplements but if those fail, then pharmaceutical options would be the next step.
On Vitamins and Supplements
Q: Patients are often overwhelmed by what to take. Do I really need all these vitamins and supplements? What's your approach to this topic?
A: I have a lot of patients that are taking various supplements. When asked why they take them, their response many times will be along the lines of "I thought/read/heard it was good to take." While some of these patients are taking it to treat a certain condition or symptom, they may not be addressing the correct or underlying cause.
Q: How do you help patients navigate what's safe vs. just good marketing?
A: Typically, I start with good history and extensive blood work. By doing that, the goal is to identify any deficiencies that can be supplemented with these products. It tends to save the patient money because they can stop taking certain supplements that aren't benefiting them.
Thank you doctor DeFeo, and we look forward to having you back soon!
