Our weight loss retreat in Thailand is for anyone ready to stop the guesswork and take charge of their health. Whether you’re a complete beginner, returning after time off, or stuck on a plateau, this programme is built to meet you where you are, and move you forward.

All fitness levels, body types, and goals are welcome. If you’re using medications like Ozempic or Mounjaro, we’ll support you with the structure and healthy habits those injections can’t provide.

You won’t be doing this alone. You’ll be part of a supportive, like-minded group who train together, eat well, and stay accountable. All in an environment that understands your journey and has your back.

We’ll pick you up from Koh Samui airport so look out for your name on a sign. After a quick ride to Lamai, you’ll check into your accommodation to get settled in.  WThen it’s time to head to the gym and get started.

Your first stop: an assessment with our senior coach. We’ll take your measurements, talk goals, and build a clear, personalised plan for your time here. You’ll meet your dedicated trainer, tour the facilities,

Next, you’ll sit down with our in-house nutritionist to review your current eating habits. Together, you’ll create a custom nutrition strategy designed to support your workouts, fuel your fat loss, and help you build sustainable habits. Then you’ll meet your coach and get to work.

Day one, done. You’re in.

You’ve officially started your Weight Loss programme in Koh Samui.

Torch fat, build lean muscle, and train with intention. Our expert-led sessions combine Muay Thai, strength training, and high-intensity workouts to maximise fat loss and accelerate your metabolism. Each workout is designed for results, with a strong focus on safe technique, proper form, and long-term success.

Our certified personal trainers are with you every step, tailoring each session to your level and helping you build the kind of habits that support sustainable weight loss, not just quick fixes. If you’re using medications like Ozempic or Mounjaro, we’ll work with you to develop the fitness, mindset, and nutrition habits those injections can’t provide.

You won’t just lose weight. You’ll gain strength, energy, and the confidence to keep progressing long after you leave Koh Fit Thailand.

GLP-1 medications like Ozempic and Mounjaro can be powerful tools for kickstarting weight loss, but they’re not a long-term solution on their own. Many people regain weight after stopping, especially if healthy habits aren’t in place. These injections may suppress appetite, but they don’t replace strength training, proper nutrition, or consistent routines that support sustainable results.

At Koh Fit Thailand, we support guests currently using GLP-1s as well as those coming off them. There’s zero judgment, only encouragement. We understand why these medications are helpful, but we also want to ensure you build the skills and confidence to rely on yourself, not just the injection.

Through structured training, balanced meals, and daily routines, our weight loss retreat gives you the tools to create real, lasting change. So you leave feeling strong, capable, and in control of your own journey.
