It definitely makes me feel fuller, I don’t know if it actually does help though.
I wrote this last year about drinking water: https://manvfat.com/how-much-water-should-you-drink/ and thought you might be interested in these bits from it:
"Water makes up 60% of our bodies and it’s lost through sweating, peeing and even breathing, so it’s important to maintain this level to stay healthy. Drinking enough water can help with digestion, your blood circulation and can help prevent headaches. On a more superficial level, drinking enough water can help improve your skin too. Simply put, water is the key to helping your body function properly. "
Will drinking more water help me lose weight?
Well, it’s not a magic potion – if you’re not sticking to your calorie goals, drinking a bit of water isn’t going to negate this. However, drinking enough water and staying hydrated is thought to help a little bit, although it’s not clear exactly how. Some people swear that drinking enough water will ‘flush everything out’, or that a glass of ice-cold water will kickstart your metabolism, but there’s no real research to back either of these claims.
The Journal of Clinical Endocrinology & Metabolism did find that drinking water increased metabolic rate by 30% for a maximum of 30 minutes, but it was a small sample with strict controls which can’t really be generalised to the wider population.
But if you’re used to drinking high-calorie soft drinks every day, switching to water will cut those calories which will help you lose weight. Another commonly-cited reason that water helps you lose weight is that drinking a lot of water will fill you up, so you may end up eating less. But again, this isn’t a magical property that water has – it’s simple calories in, calories out.
This doesn’t mean that it’s not worth drinking water if you want to lose weight, though."
