Is My Fruit Intake Too High While Trying to Lose Weight?

Is this weight loss fruit considered excessive?

I am currently in a weight loss period.
Besides having normal breakfast and lunch, I eat fruit before meals.
For example, I have lunch around noon and eat fruit around 11:30 AM, then have lunch at noon.
In the afternoon, besides drinking water, I usually have some fruit (like guava or oranges, not always the same) around 3:30 to 4 PM.
This week, I started drinking fresh juice, using about 6 to 8 oranges plus one lemon to make a 500cc cup of juice (with no added substances, including water)!
1.
Is my fruit intake too high?
2.
Will drinking orange juice at 4:30 PM cause me to gain weight?
Note: I do not eat dinner! (The fruit I have is essentially my dinner) OR I might have some stir-fried vegetables (but I usually soak them in hot water before eating).

Dear Xiaobaimi,
Hello! When it comes to weight loss, it is essential to base your diet on balanced nutrition while adjusting caloric intake.
It is also important to pay attention to the appropriate distribution of the three macronutrients and calories across meals (the caloric distribution for breakfast, lunch, and dinner can follow a 1:1:1 or 1:2:2 ratio).
According to what you mentioned, your fruit intake is indeed excessive.
While fruits are rich in vitamins, minerals, and dietary fiber, we must not overlook that they also contain a significant amount of fructose.
One gram of fructose provides 4 calories, and excessive intake can hinder weight control and may also convert into triglycerides (a type of blood fat).
The daily dietary guidelines from the Department of Health recommend consuming 2 servings of fruit per day (with each serving being approximately the size of a fist).
Your current intake of about 10 servings per day is much higher than the recommended amount.
It is best to consume fresh fruits rather than fruit juices, as some vitamins in fruits can be destroyed during the juicing process due to exposure to light and air, and fiber can also be lost.
Additionally, to produce drinkable juice, a larger quantity of fruit is required, which can lead to overconsumption.
As previously mentioned, weight loss must be based on a balanced diet, so dinner should also include appropriate amounts of staple foods, protein sources (such as eggs, beans, fish, and meat), and fats.
You cannot rely solely on vegetables and fruits, as different food groups serve different functions.
However, foods within the same group can be substituted.
This means you can skip rice but must consume other staple foods (such as noodles, steamed buns, or corn), and you cannot replace staple foods, protein sources, or fats with vegetables or fruits.
Additionally, you should not skip dinner entirely.
During your weight loss period, you can increase your vegetable intake (while ensuring adequate hydration) and appropriately reduce the amount of staple foods, but you cannot eliminate them completely to avoid the risk of ketoacidosis or other metabolic disorders.
Sincerely,
Dietitian Shih Kuei-Mei

When it comes to weight loss, managing fruit intake is crucial, as fruits, while healthy, can also contribute to your overall caloric intake. Based on your description, it appears that your fruit consumption may indeed be higher than recommended, especially considering your goal of losing weight.

1. Fruit Intake Assessment: The general guideline for fruit consumption is about 2 servings per day, which translates to roughly the size of a fist for each serving. From your account, it seems you are consuming fruit before lunch and again in the afternoon, along with a significant amount of fresh juice made from 6-8 oranges and a lemon. This could easily amount to 10 servings or more of fruit in a single day, which is substantially above the recommended amount. While fruits are rich in vitamins, minerals, and dietary fiber, they also contain natural sugars (fructose) that can contribute to your caloric intake. Excessive consumption can lead to weight gain, as the body can convert excess sugars into fat.

2. Impact of Juice on Weight: Drinking freshly squeezed juice, especially in large quantities, can lead to an increased caloric intake without the fiber that whole fruits provide. For example, a single orange contains about 60 calories, but when juiced, you may consume the calories of several oranges in one sitting without feeling as full as you would if you ate the whole fruits. This can lead to a caloric surplus, which is counterproductive for weight loss. Additionally, consuming juice in the afternoon, especially if it is high in sugars, can spike your blood sugar levels, potentially leading to increased hunger later on.

Dinner Replacement with Fruits: You mentioned that you skip dinner and replace it with fruits or some stir-fried vegetables. While incorporating vegetables is beneficial, relying solely on fruits for dinner may not provide a balanced intake of nutrients. A well-rounded meal should include a source of protein (like lean meats, beans, or tofu), healthy fats (like avocados or nuts), and whole grains (like brown rice or quinoa). This balance is essential for maintaining energy levels, supporting muscle mass, and ensuring that your body receives all the necessary nutrients.

Recommendations:
- Limit Fruit Intake: Aim to reduce your fruit intake to about 2-3 servings per day. Focus on whole fruits rather than juices to benefit from the fiber content, which aids in digestion and helps you feel full.

- Balanced Meals: Consider incorporating a balanced dinner that includes protein, healthy fats, and whole grains. This will help you feel satisfied and reduce the likelihood of cravings later in the evening.

- Monitor Portion Sizes: Be mindful of portion sizes for all foods, including fruits. Using measuring cups or a food scale can help you better understand serving sizes.

- Stay Hydrated: Continue to drink plenty of water throughout the day, as hydration is key in any weight loss plan.

In conclusion, while fruits are an essential part of a healthy diet, moderation is key, especially when trying to lose weight. By adjusting your fruit intake and ensuring balanced meals, you can create a more effective weight loss strategy that supports your overall health. If you continue to struggle with weight loss or have concerns about your diet, consider consulting with a registered dietitian or nutritionist for personalized guidance.
