Meal replacement for weight loss / Is it really possible to drink more water?

Hello, Doctor.
I am currently using Herbalife products for weight loss, and I have noticed that they all claim that drinking plenty of water is essential for effective weight loss (suggesting a water intake of 30 to 70 times my body weight in ounces).
This means I am required to drink at least 6000cc of water daily, spread throughout the day.
Is it really possible to consume this much water? Initially, my intake was about 2000cc per day, but after forcing myself to drink more water, I started to feel thirsty, and now I can easily drink 5000 to 6000cc of water...
which makes me go to the bathroom frequently.

Additionally, I am consuming a lot more vegetables during lunch than before, but I’ve noticed that my stool is green.
I've never had green stool from eating more vegetables before.
I also take a large amount of fish oil, about six capsules (which is said to help reduce visceral fat), and several vitamins...
the quantity is quite surprising.
The instructions state that excessive consumption is not beneficial, which contradicts the claims made by the distributors.
Currently, I do not feel any unusual symptoms, but I have significant concerns about the water intake.
Moreover, the information I found online is inconsistent.
I hope you can clarify these issues for me.
Thank you very much.

Hello: Typically, weight loss medications are designed to increase satiety to prevent overeating, which is why they often contain substances that expand in water, necessitating increased water intake.
This is indeed a requirement for weight loss medications.
However, if you drink too much water, it is advisable to slightly supplement with some salt to avoid electrolyte imbalance.
Vegetables usually do not cause green stools; it is likely due to the color of the medication, which you may need to inquire about with the distributor.
Water-soluble vitamins can be excreted through urine and are less likely to cause toxicity, whereas fat-soluble vitamins should not be taken in excess, such as vitamins A, D, and E.
You can check the ingredient list and compare it with the recommended intake levels.
Thank you for your question.

Drinking water is essential for overall health, but the relationship between excessive water intake and weight loss is nuanced. While hydration plays a crucial role in metabolic processes, drinking excessive amounts of water does not directly lead to weight loss. Instead, it can have various effects on your body, some of which may be counterproductive.

Firstly, the recommendation to drink water based on body weight (30-70 mL per kg) is a general guideline. For an average adult, this typically translates to about 2-3 liters of water per day, depending on factors like activity level, climate, and diet. Drinking 6000 cc (or 6 liters) of water daily is significantly above this recommendation and may lead to potential health issues, including water intoxication or hyponatremia, where sodium levels in the blood become dangerously low. Symptoms of hyponatremia can include headache, nausea, confusion, and in severe cases, seizures or coma.

Your experience of feeling thirsty after increasing your water intake suggests that your body is adjusting to a higher fluid intake. However, it is essential to listen to your body and not force excessive amounts of water. If you find yourself urinating frequently, it may be a sign that you are drinking more water than your body needs.
Regarding your bowel movements being green, this could be attributed to the increased intake of vegetables, which are high in chlorophyll, or possibly the supplements you are taking. Some vitamins and supplements can cause changes in stool color, particularly those that are colored or contain certain dyes. If you are concerned about this change, it may be worth discussing with a healthcare provider to rule out any underlying issues.

As for the fish oil and vitamins, while omega-3 fatty acids from fish oil can be beneficial for heart health and may help reduce visceral fat, it is crucial to adhere to recommended dosages. Overconsumption of fat-soluble vitamins (like A, D, E, and K) can lead to toxicity, as these vitamins accumulate in the body. Always check the recommended daily allowances and consult with a healthcare professional if you are unsure.

In terms of weight loss, while staying hydrated is important, it should be part of a broader strategy that includes a balanced diet and regular physical activity. Drinking water can help with satiety, potentially reducing overall calorie intake, but it should not be relied upon as a sole method for weight loss. Instead, focus on a sustainable approach that includes whole foods, adequate protein, healthy fats, and fiber-rich carbohydrates, along with regular exercise that suits your physical condition.

In conclusion, while hydration is vital, moderation is key. Aim for a balanced intake of water that meets your body's needs without exceeding it. If you have specific weight loss goals or dietary concerns, consider consulting a registered dietitian or healthcare provider who can provide personalized advice based on your individual health status and lifestyle.
