16:8 intermittent fasting: How it works

Studies show that 16:8 works better if you don’t eat too late and start your first meal of the day earlier. So rather than start your breakfast at 11am and your last meal at 7pm, I suggest starting your first meal at 9am and finishing your last meal around 6pm. Why? Fasting works better if you don’t go to bed on a full stomach and have your last meal at least four hours before bedtime. Not only will you sleep better but the diet will work better for you.

Eating within an eight hour window does not mean you can gorge on processed foods and fizzy drinks and still expect the same results. Ensure you are getting at least 25g of lean protein at each meal and at least 25g of fibre a day. You can do this by focussing on consuming plenty of wholegrains, plants and legumes as well as fatty fish, nuts and seeds.

One thing you need to avoid as much as possible is alcohol. A glass of wine can be around 225 calories and if you’re restricting your eating within an eight hour window you need to fill it with nutrient dense calories rather than empty ones. Drinking also can lead to unnecessary snacking. It also spikes your blood sugar which in turn contradicts the benefits of fasting.

One of the benefits of TDE is that you have more time to sleep. A good night’s sleep is fundamental for rest, relaxation and weight loss. The better night’s sleep we have, the less likely we are to experience energy crashes and reach for carb-rich and sugary filled snacks. Sleep is key towards ensuring your cortisol levels don’t spike. When your cortisol levels spike it derails your hormones and can lead to belly fat storage.  

Aim to drink around eight glasses of just plain water. If it’s a particularly hot day or if you’re having a physically active one, drink according to your thirst levels. You may need up to ten glasses. If you’re not keen on plain water, add a slice of lemon or lime to add a little flavour and vitamin C.
