An apple a day keeps the doctor away? Drink more water to help you lose weight? Eating carrots helps your eyesight? Grapefruit and vinegar burn calories? Eating after 8m will make you fat? I’m sure you can think of many more, but perhaps one of the above is actually true!!
As reported in The Economist – A 12 week study has recently found that drinking water before meals does lead to weight loss….
The study was conducted on 48 ‘inactive’ Americans aged 55 – 75 years old. The group was halved with one group instructed to drink ½ litre of water just before their breakfast, lunch and dinner. The other control group did nothing.
It was reported that prior to the research all participants were eating 1800 – 2200 calories per day. At the start of the research all participant’s daily calorie allowance was controlled to 1200 for females and 1500 for males.
After 12 weeks it was found that the ‘water drinking group’ had lost on average 7kg each compared to only 5kg per person in the control group. Fast forward 12 months and the researchers interestingly found that the participants in the water drinking group had permanently adopted the habit and continued to lose on average 700g in 12 months whereas the control group had sadly gained their weight back after the experiment.
The Economist labeled this article as water being a magic elixir to promote weight loss – but trust me there is no trickery involved – just human physiology.
Needing to know more to comment further on the study I’m going to tell you a fact about why water can help you lose weight. Simple – it makes you feel full so you eat less. Water is not removed from the digestive tract until the large intestine – so it keeps you full for a very long time – nearly all the way to the other end infact! And water contributes to the 350 grams of contents that your stomach needs to engage the satiety response (your brain receives a chemical to tell you it’s full) So, this should make you consume less calories when you eat if your stomach is already quite full.
What I don’t know about this experiment is if the water drinking group actually consumed all of the meals (or they had to leave some behind on the plate which is my assumption) and if they reduced their snacking throughout the day.
All things considered, for such a minimal change to your life it can produce a grateful outcome. So next time you feel hungry, before you eat try drinking 2 large glasses of water and see if you feel more full so you don’t eat everything on your plate.
Your waist will love you for it!
