Exercise


If I eat two apples at 4:00 PM and then exercise at 4:30 PM, will it harm my stomach, and if I exercise until 5:30 or 6:30 PM before having breakfast?

Hello! I apologize for the delay in responding to your question due to my busy schedule.
Generally, it is not recommended to engage in vigorous exercise immediately after eating.
However, if your activity consists of light exercises such as walking, it should be fine, although it still depends on your individual gastrointestinal condition (I suggest consulting a gastroenterologist regarding your specific situation).
As for the two apples you mentioned before meals, that is actually a considerable amount, containing approximately 120-240 calories, which is equivalent to the caloric content of a bowl of rice (210 calories).
I recommend replacing that with one small apple (about the size of a fist) or a cup of 240cc of milk as a pre-exercise snack.
This way, you can avoid excessive hunger before exercising while ensuring a healthy and manageable intake.

Exercising after eating can be a concern for many, especially when it comes to the timing and type of food consumed. In your case, eating two apples at 4:00 PM and then exercising at 4:30 PM raises some important considerations regarding digestion and exercise.

First, let's discuss the digestion process. When you eat, your body directs blood flow to the stomach and intestines to aid in digestion. This process can take anywhere from 30 minutes to several hours, depending on the type and quantity of food consumed. Apples, while healthy, are high in fiber and can take longer to digest, especially when consumed in larger quantities. Eating two apples (which can contain around 120-240 calories) shortly before exercising may lead to discomfort, such as cramping or nausea, particularly if the exercise is vigorous.

If your workout consists of light activities like walking or gentle stretching, you may not experience significant discomfort. However, if you plan on engaging in more intense workouts, it might be wise to adjust your pre-exercise snack. A single small apple or a small serving of yogurt could provide the necessary energy without overwhelming your digestive system.

Now, regarding your post-exercise routine, you mentioned exercising until 5:30 PM and then having breakfast at 6:30 PM. It’s crucial to refuel your body after exercise, especially if you’ve engaged in moderate to intense physical activity. The post-exercise meal should ideally include a combination of carbohydrates and protein to replenish glycogen stores and aid muscle recovery.
Research suggests that consuming a meal or snack within 30 minutes to two hours post-exercise can significantly enhance recovery. This meal could include options like a smoothie with fruit and protein powder, a whole-grain wrap with lean protein, or even a bowl of oatmeal topped with nuts and fruit.
In terms of nutrition, it’s essential to maintain a balanced diet throughout the day. If you’re focusing on weight management or fitness, consider the overall caloric intake and the quality of the foods you consume. While fruits like apples are nutritious, they should be part of a varied diet that includes vegetables, whole grains, lean proteins, and healthy fats.

To summarize, while it may not be harmful to eat two apples before exercising, it could lead to discomfort, especially if the exercise is intense. Opting for a smaller portion or a different type of snack may be more beneficial. After exercising, prioritize a balanced meal that includes both carbohydrates and protein to support recovery. Always listen to your body and adjust your eating and exercise habits based on how you feel. If you have specific dietary concerns or health conditions, consulting with a healthcare professional or a registered dietitian can provide personalized guidance tailored to your needs.
