Around 100-200 kcal difference each day
(from lower energy, movement, and increased hunger)
thatâs around = 700-1,400 kcal/week
= 3,000-6,000 kcal/month
=~0.4-0.8 kg of body fat per month (since ~7,700 kcal = 1 kg fat)
Now, the difference between drinking 500ml vs 2L of water
isnât that water âburns fatâ...
Itâs what hydration changes in your body that affects fat loss indirectly:
500ml/day (low hydration)
â reduced training quality
â more fatigue â less daily movement (NEAT drops)
â weaker appetite regulation between meals
Hunger is the biggest problem of all, your brain often mistakes thirst for
hunger up to ~60% of the time...
dehydration is increasing your likelihood of overeating.
Letâs compare to if you drank 2L / day:
â better training output â higher calorie burn
â more natural daily movement
â improved hunger control
â better metabolic efficiency
Fat loss is always a long-term calorie deficit game.
So even small daily performance drops (100-200 kcal) donât look like much...
But they compound into real fat loss differences over weeks and months.
5 tips you can action tomorrow to get an extra 1.5L into your day:
1. start your morning with 500ml
2. drink 300-500ml with every meal
3. carry a bottle with you everywhere you go
4. set 3 simple reminders during your day
5. pair water with habits you already do
BONUS: make it taste slightly nicer with sugar free cordial, or some frozen berries.
