Hello doctor,

I will try to keep this short. I had a quick question. I have eaten really bad for a very long time, but over the past week I have completely changed up my diet. I do not eat processed foods, bad sugars and fats, and hardly any gluten. I have been eating chicken/salmon mainly, fruits, veggies, and unsaturated fats mainly. I have been taking a couple weight loss supplements as well since yesterday. Before I took the supplements yesterday my lower part of my stomach has had a little pain. Is that because my stomach is trying to adjust to the change in my diet? Thank you.



Welcome to

First, I would appreciate the fact that you have switched from unhealthy eating habits to a healthy diet and healthy eating habits. Stay motivated. If a person had been into extensive unhealthy eating habits from a long time, it may be difficult for his digestive system to adjust. The digestive system needs some time to adjust if you have been eating a lot of fiber (fruits and vegetables) recently. Gradually increase fiber in your diet as your stomach needs some time to get accustomed to it. The pain may be due to more intake of dairy products.

Increase dairy products gradually. Low or high intake of certain healthy foods can cause bloating or gas. But it does not mean that you should go back to unhealthy eating habits. The pain must not demotivate you. Consistency is the key. If the pain persists, make sure to go to a physician or GI specialist. Moreover, you can eat gluten if you do not suffer from gluten intolerance. You can eat oats, barley, whole wheat. Just do not eat refined flours and cereals. Do not fall into the trap of buying everything from the market that is labeled as healthy.
