Improving Sleep Quality Through Nutrition
Did you know that the quality of your sleep affects your weight loss process? Indeed, various hormones are secreted during certain phases of sleep, including leptin and ghrelin, the hormones responsible for hunger and satiety feelings, as well as growth hormone, which is responsible for the production of lean tissue (muscles), among other things. In addition, proper recovery following a good night’s sleep will enable you to attack your training sessions vigorously and effectively, thus promoting weight loss.
If you do not get much sleep, go to bed very late, or if your sleep is interrupted, reaching your weight loss objective may be harder.
Here are the golden rules to follow during supper to ensure a better sleep:
Avoid having a meal too high in protein
Large servings of meat and alternatives (the recommended serving is about the size of a deck of cards) are said to interfere with sleep for insomniacs, because they promote the production of dopamine, a neurotransmitter associated with motor activity and aggressiveness, among other things.
Avoid having a meal high in fats
In high quantities, lipids slow down the digestive process and increase body temperature, just as proteins do. Inversely, deep sleep is enhanced by a drop in body temperature.
Avoid caffeine six hours prior to bedtime
Everything containing caffeine, such as coffee, tea, yerba mate, energy drinks, soft drinks, and chocolate should be avoided at night. Caffeine stimulates the nervous system and disturbs the activity of two neurotransmitters that are essential to sleep induction, that is, melatonin and adenosine.
Reduce your alcohol consumption, or avoid it altogether
Although alcohol helps falling asleep, it hinders deep sleep. Indeed, alcohol is said to prevent the secretion of adrenalin (stress hormone), and disturb the activity of tryptophan and serotonin, two sleep regulating neurotransmitters.
Also, think about allowing yourself a moment of relaxation before going to bed!
