Medical Weight Loss & Gut Health in Washington, DC

I am incredibly grateful for the care and expertise of Dr. Janese Laster at Gut Theory Health. Through her intentional, thoughtful approach and deep knowledge, she has helped me lose weight, get off blood pressure medication, and feel healthier and more confident than I have in a long time.

Dr. Laster is not only highly skilled, but also incredibly personable and truly invested in her patients and their outcomes. You can feel that she genuinely cares, listens, and tailors her guidance to support lasting, real-life change. I highly recommend her to anyone looking to improve their health with a physician who combines expertise with compassion.

Honestly, could not ask for better care. Dr. Laster and her team are knowledgeable, warm, caring, and genuinely invested helping their patients become healthier versions of themselves. I came in with lots of questions and preconceived notions about weight loss, weight-loss medication and weight loss procedures. Dr. Laster answered every one of my questions and then some, but also empowered me throughout the process. This isn’t a quick fix, it’s not the easy way out, but truly a lifestyle change, as I have been equipped with the tools to become the healthiest version of myself.

Gut Theory has changed my life!

I cannot recommend Dr. Laster and her team enough, especially Ms. Lucretia! Before my first consultation, I didn’t even know weight loss specialist doctor’s existed, so I wasn’t sure what to expect. From the moment my appointment began, I felt completely at ease. Dr. Laster took the time to really listen to me—my goals, struggles, likes, dislikes, and even my concerns. It was clear from the start that her approach is truly individualized, designed to meet each patient’s unique needs…

I had the pleasure of working with Dr. Laster during a challenging time with chronic illness (Crohn’s) and weight management. Upon meeting with Dr. Laster, I shared my concerns and how I had been committed to tracking weight challenges and my diet. It was then that I knew that she was skilled at not only understanding her patient’s needs, but developing a plan of action that was comprehensive and individually based. She evaluated my medical history and connected with my current GI (who actually recommended Dr. Laster as she agreed with my weight concerns) to insure that we were all on the same page with how to proceed…

I cannot express enough how amazing the ladies at GT are! When I first met them a few years ago, I was at my wit’s end, looking for one last attempt to lose weight. I walked into my appointment filled with negative thoughts and doubts. However, the team was incredibly patient and reassuring, emphasizing that my goals were achievable as long as I was willing to put in the effort. They promised to support me every step of the way, which was exactly what I needed to hear.
