I remember the first time I cleaned up my diet. And trust me, I’ve had to do it many times since—and will probably do it again!
At first, I felt like absolute crud. I had a headache, my stomach wasn’t happy, and let’s just say I wasn’t the most pleasant person to be around.
The good news? Those feelings didn’t last long.
But if you’ve ever cleaned up your eating and felt worse instead of better at first, you’re not alone. It can catch you off guard—after all, shouldn’t making healthier choices make you feel amazing right away?
Here are a few reasons why you might feel a little “off” when changing your diet:
- Detox symptoms: When you cut out processed foods, sugar, or other common culprits, your body has to adjust. This can lead to headaches, fatigue, and irritability, but it’s temporary. Stick with it, and you’ll start feeling better soon.
- More fiber than usual: If you suddenly increase your fiber intake, your digestive system might struggle to keep up. Try making gradual changes instead of overloading all at once.
- Dehydration: If you’re eating more fiber, your body needs more water to help everything move smoothly. Not drinking enough can make you feel worse instead of better.
- Lack of planning: Cleaning up your diet is much easier when you’re prepared! Without a plan, it’s easy to under-eat or end up with unbalanced meals.
Just remember, your body will adjust—it just takes time. And if you’re feeling off for an extended period, check in with your healthcare provider to make sure everything is on track.
Stick with it, and you’ll be feeling better before you know it!
