Why you might feel flat after losing weight on injections

· Dr Rachel Megahy

You have lost the weight, or most of it. Clothes fit. People have noticed. By every outside measure, this is what you wanted for years.

And the feeling does not arrive. Where the triumph was supposed to be, there is flatness, and underneath it something like disappointment, though it is hard to say in what.

If that is you, you are far from alone. It is one of the most common experiences people have on weight-loss injections, and one of the least talked about, because it sounds ungrateful.

Why it happens

Wanting something is a state, and states end. Wanting a different body for fifteen years is an occupation. It gives effort a direction and holds a promise about the future. When the wanting stops, that structure goes with it, and the space is not automatically filled with satisfaction.

The weight usually stood for something else. When people describe what they pictured before they started, the body is often the smallest part. They pictured being comfortable in photos, being taken seriously, a different response from a particular person, or simply feeling acceptable. A smaller body can deliver some of that. Much of it was never weight-shaped.

You brought yourself along. The same relationships, the same work, the same difficulties. That is obvious when stated and genuinely surprising when lived.

The trap: going further

The most common conclusion is that you have not lost enough yet. If the feeling did not arrive at this size, perhaps it will at the next one.

It usually does not, and that conclusion can turn an anticlimax into a pursuit with no end point. It is also often behind the wish for a higher dose when the loss slows.

What helps

Name it as normal. It is.

Let the loss be a loss. Something did end: a project, an explanation, a version of the future where everything would be better afterwards.

Write down the gap. What you pictured, what has actually changed, and what has not changed that you expected would. The third list usually tells you where the flatness lives.

Address those things directly, not through your body. Some you can work on yourself, some with help.

When it is more than flatness

If low mood covers everything rather than this one area, and has done for weeks, or comes with hopelessness, speak to your GP. That is worth proper attention, and it is treatable.

The arc of weight-loss treatment rarely goes the way people are told. When the Noise Stops has a module on exactly this middle stretch: the plateau, the gap between what you expected and what you got, and feeling flat on arrival.
