When you came looking for an easy fix, but something else has to come first

What follows combines several people's visits into one reconstructed account. It is not any one person's story, and anything that could identify someone has been removed.

How do people describe it when they come in?

They come in thinking of something easy to take. The first thing they say is that they're too busy to set aside time.

Many have long lived with late meals because of work and frequent work dinners. When we ask, it's not just that their weight has gone up — they're always tired, and their stomach and bowel movements are irregular.

Why not start right away? Why look at other things first?

Because if you try to lose weight while the fatigue and gut problems stay as they are, it won't last. Without energy, whatever you decide is hard to keep up.

When the gut is irregular, absorption slows, and when absorption slows, the "that's enough" signal arrives late. If you only cut back the amount in that state, all that's left is putting up with it.

So at the first visit, we often rearrange the order for you. Since this differs from what you had in mind when you came in, we explain why first.

What do we look at?

Along with body composition, we look at how your day runs. We write down exactly when you eat, when you sleep and how often you have work dinners.

We also look at your belly and bowel movements. If your stomach often hurts or your stools are loose and irregular, we deal with that first.

How do we treat it?

We look at fatigue, the gut and weight as one thread. We don't treat them separately; we work through them in order within a single prescription.

We don't set a diet you can't stick to. If you can't get out of work dinners, we decide what you can stick to within them — things like what to eat first and what to leave.

The same goes for exercise. If you can't set aside time, we start by walking more in daily life and with things you can do in a short time. It's better not to make plans you can't keep.

How did people do?

What changes first is the morning. Getting up becomes less hard, and then we tend to see the stomach and bowel movements become regular.

Weight moves after that. If we don't explain this order at the start, people only see it as "Why am I not losing weight?"

What are the limits of this approach?

If your circumstances make it hard to change your lifestyle, treatment goes that much slower too. We tell you that plainly at the start.

If your fatigue is severe, things that show up on blood tests — such as anemia, thyroid problems or blood sugar — need to be ruled out first. Bring those results and we'll go over them together.

If you share the same concern

  1. If fatigue and gut problems stay as they are, trying to lose weight alone won't last.
  2. When the gut is irregular, absorption slows and the fullness signal arrives late.
  3. The order may differ from what you had in mind — we explain why first.
  4. We don't set a diet or exercise plan you can't stick to.
  5. If fatigue is severe, things that show up on blood tests come first.

We don't look only at the number on the scale. Why the weight went up differs from person to person, so we start by finding that reason.

If you keep losing weight and gaining it back, come and see us. Before the number on the scale, we first look for why the weight went up. It's different for everyone.

Because there are many possible causes, progress differs from person to person, even with the same care.

I mainly see problems that start with body alignment and posture. I'm in charge of care that requires looking at the balance of the whole body, such as children's growth, weight loss and recovery after car accidents. I have published meta-analyses on fatigue in international journals. That research experience helps when I see patients whose fatigue doesn't go away no matter how much they rest.
