Weight Management: Stop Negative Thoughts

Table of Contents


It can be hard to get to and stay at a healthy weight. It takes healthy eating and regular exercise. These can be hard changes to make. But you can help yourself succeed just by thinking that you can succeed. If you tell yourself negative things—"I can't do this. Why bother?"—change will be harder. But if you encourage yourself with thoughts like "I can do this," you can raise your chance of success.

With time and practice, you can change what you say to yourself. You can learn to think in a healthy way even when you make a mistake.

How can you use healthy thinking to reach a healthy weight?

Notice and stop your thoughts

The first step is to notice and stop your negative thoughts or "self-talk." Self-talk is what you think and believe about yourself and your experiences. It's like a running commentary in your head. Your self-talk may be rational and helpful. Or it may be negative and not helpful.

Ask about your thoughts

The next step is to ask yourself whether your thoughts are helpful or unhelpful. Look at what you're saying to yourself. Does the evidence support your negative thought? Some of your self-talk may be true. Or it may be partly true but exaggerated. There are several kinds of irrational thoughts. Here are a few types:

Choose your thoughts

The next step is to choose an accurate, helpful thought to replace the unhelpful one.

Keeping a journal of your thoughts is one of the best ways to practice stopping, asking, and choosing your thoughts. It makes you aware of your self-talk. Write down any negative or unhelpful thoughts you had during the day. If you think you might not remember them at the end of your day, keep a notepad with you so that you can write down thoughts as they occur. Then write down helpful messages to correct the negative thoughts.

If you do this every day, helpful thoughts will soon come naturally.

But there may be some truth in some of your negative thoughts. You may have some things you want to work on. If you didn't perform as well as you would like on something, write that down. You can work on a plan to correct or improve that area.

If you want, you also can write down what kind of irrational thought you had. Your journal entries might look something like this:

Thought diary

Stop your negative thought

Ask what type of negative thought you had

Choose an accurate, helpful thought

"I ruined my eating plan by having so much pizza tonight."

Focusing on the negative

"I wish I didn't eat so much pizza. But it's only one meal. I stayed on my eating plan really well the rest of the week."

"I should never have pizza or dessert."


"Having dessert or pizza now and then is okay if it's part of my eating plan."

"I can never stick with an exercise plan."


"I've had some problems sticking with an exercise plan in the past. But that doesn't mean I can't do it in the future. I've made other changes in my life."

"If I can't lose 10 pounds this month, then I'm going to give up this eating plan."

All or nothing

"I'm going to try to set a realistic goal. It may be a smaller goal than before, but I'm still working toward a healthy weight."
