A less invasive way to lose weight.

Two small magnets make a short cut inside your gut, so you feel full with smaller meals, absorb fewer calories and the weight stays off.

The difference

Why This Lasts When The Others Didn't

Diets
Your body fights back with hunger, and the weight creeps back.
Weight loss medication
Works while you take it. Stop, and the hunger returns, and the side effects and monthly cost add up.
Operations that remove or staple part of your stomach
They last, but recovery takes weeks, and what's removed can't be put back.
MagDI™
Done once. Less invasive than a gastric bypass or sleeve, so it's safer and you recover faster: home the next day, back to desk work in about a week. You feel full sooner and absorb fewer calories, so you lose weight and it stays off.

“…I felt it was the first time in my life I was genuinely being listened to and not just blamed or judged for being overweight.”

Sarah K., Trustpilot, April 2026
In plain words

How MagDI™ Helps You Lose Weight

  1. Illustration of the digestive system, with the two small magnets meeting through the wall of the gut

    No cutting, no staples

    You swallow one small magnet. While you're asleep, Dr Loy places a second one close by, and the two click together. Nothing is cut away or stapled.

  2. Illustration of the magnets, still joined, moving on through the intestine after the new path has formed

    Nothing is left inside you

    Over two to three weeks, the magnets gently open a small shortcut for your food. Then they leave your body naturally. You won't feel it.

  3. Illustration of food, shown in yellow, taking the short cut through the new doorway

    Smaller meals feel like enough

    Food that takes the shortcut reaches the part of your gut that says “I'm full” sooner. So you're satisfied with less, and you're not hungry all the time.

Feeling nervous?

Worried About An Operation? That's Normal.

“It's a big operation and I'd be out for weeks.”
About an hour asleep, home the next morning, back to desk work in about a week.
“It's forever.”
It's reversible. Nothing is removed, so the new path can be closed again if it's ever needed.
“I have type 2 diabetes and high blood pressure.”
That's often why people come to us. Both often ease as the weight comes off.
“I'll be judged.”
Not here. You'll be listened to, not lectured.

Whatever is on your mind, ask it at your free assessment. That's what it's for.
