If you are currently watching what you eat and trying to drop weight healthily, there is one simple habit that is often overlooked and it does not cost a single cent. Before you scroll past thinking you already know what I am about to say, hear me out, because I was exactly the type of person who brushed this off for years too.
I am talking about drinking enough water daily, and specifically, what happened when I finally started taking it seriously.
I Was That Person Who Barely Drank Water
For the longest time, I only drank water when I felt thirsty. I knew somewhere in the back of my mind that drinking more water was good for you, but I never paid much attention to how much I was actually taking in. It felt like one of those things everyone says but nobody really tracks.
That changed when I came across a 1.7 litre bottle that, oddly enough, made drinking water enjoyable for me. Before that, I had tried bottles with openings so small the water barely trickled out, and others so wide they would splash all over me the moment I took a big gulp. Finding the right bottle with the right mouth size sounds like a small thing, but for me, it made a real difference in building the habit.
How I Built Up My Water Intake Gradually
I did not force myself to chug water from day one. Instead, I started slowly, drinking about half the bottle daily, and I noticed I was making more trips to the toilet than usual. Within a week or two, I was finishing the full bottle. By around the one-month mark, I had worked my way up to two bottles a day, which is roughly 3 litres.
What I found most encouraging was that I never pushed myself. I simply reminded myself to drink and let my body adjust at its own pace. Eventually, my body started signalling me on its own when it needed water. That felt like a real turning point because it meant the habit had genuinely taken hold.
What I Actually Noticed After Increasing My Water Intake
The change I felt most immediately was during my workout sessions. My performance noticeably improved once I was consistently hydrated. This lines up with what researchers at the University of California, San Francisco found in a 2024 systematic review, which confirmed that adequate hydration is one of the most well-supported interventions for improving physical performance and overall health outcomes.
The second benefit I noticed was feeling less hungry, particularly in the evenings. I found myself reaching for late night snacks and supper far less often. Research from Virginia Tech supports this, with studies showing that drinking 500ml of water before each main meal led to significantly greater weight loss compared to dieting alone, as water helps reduce the feeling of hunger going into a meal.
That said, I want to be honest here: water is not a magic solution that removes hunger completely. You will still feel hungry, and there will still be moments where your self-discipline needs to step in. Water helps you manage hunger more easily, but it works alongside a healthy diet and not as a replacement for one.
Why Your Muscles and Body Need Water
Without going too deep into the science, here are a couple of things worth knowing. Your muscles contain a significant amount of water and need it to function and grow properly. Your blood also relies on adequate hydration to flow efficiently, which in turn supports how well your muscles perform during exercise. According to Johns Hopkins Medicine, water plays a critical role in nutrient transport, thermoregulation, and waste removal throughout the body, all of which directly affect how well you train and recover.
The Toilet Trips Are Actually a Good Sign
Yes, drinking 3 litres of water daily means more frequent trips to the toilet. I won’t pretend otherwise. But rather than seeing this as an inconvenience, I think of it as my body doing its job, flushing out waste and keeping things moving. It is a sign that your kidneys are working well and your body is properly hydrated.
How Much Is Too Much
According to Cleveland Clinic, drinking excessively large amounts of water in a short period can cause a condition called hyponatremia, where sodium levels in the blood drop dangerously low. While this is rare under normal circumstances and typically associated with extreme cases such as endurance athletes or those with certain medical conditions, it is still a good reason to stay within sensible limits.
The recommended adequate intake according to the Institute of Medicine is approximately 3 litres of beverages per day for adult men and 2.2 litres for adult women. My personal approach is to stay within the 2 to 3 litre range and, above all, listen to my body. If it is asking for water, I drink. If it is not, I do not force it.
A Simple Way to Build the Habit
Here is what worked for me and what I would suggest giving a try:
- Find a water bottle you genuinely enjoy drinking from, the size and the mouth opening both matter more than you think
- Start with a smaller daily target and build up gradually over several weeks
- Do not force yourself to hit a number, let your body adapt at its own pace
- Use your workout sessions as a reminder to hydrate before, during, and after
- Pay attention to your hunger signals, sometimes what feels like hunger is actually your body asking for water
The Bottom Line
Increasing my daily water intake was one of the simplest changes I made, and it has had a surprisingly meaningful impact on both my workouts and my diet. It costs nothing, requires no special equipment, and the only adjustment you need to make is remembering to do it consistently.
Keep your intake within the 2 to 3 litre range, build the habit gradually, and as always, listen to your body. It usually knows what it needs.
