A recent study by Vanderbilt University, USA shows that it’s not just how many calories you eat, but WHEN you eat them that will determine how well you burn those calories.
We have all heard that “breakfast is the most important meal of the day”.
It turns out, this is more important than we imagined, for weight management!
Your daily biological clock and sleep regulate how the food you eat is metabolized.
Your body either burns stored fats or burns carbohydrates, and that choice depends on the time of day or night.
Your body’s circadian rhythm has programmed your body to burn fat when you sleep, so when you skip breakfast and then snack at night you delay burning the fat.
The experiments showed that a late-evening snack flipped a switch on fat/carbohydrate preference.
The late-evening snack session resulted in less fat burned when compared to the breakfast session.
Essentially, calories eaten at breakfast are used as fuel throughout the day.
Calories eaten later in the evening replenish the body’s fat stores.
If you want to avoid replenishing those fat stores – if you want those fat stores to be burned up as you sleep – avoid eating in the evening.
The longer your fast between your last evening meal and your first meal the next day – your break fast – the more of that stored fat is used up.
This study has important implications for eating habits, suggesting that a daily, and extended, fast between the evening meal and breakfast will optimize fat loss.
