You work hard on your fitness goals during the day, but what if your evening routine is getting between you and your goals?
Unfortunately, Poor sleep can derail the best laid plans and block the most sincere daytime efforts.
I will discuss why sleep is so important, what ingredients will get you the best Zzzs, which will burn fat at night without keeping you awake, and review 11 of the best nighttime fat burners available today.
What’s so Bad about Cortisol?
When you do not get enough rest or are stressed, levels of cortisol are raised.
Lack of sleep and stress put your body on high alert and signal your body to hang on to fat.
This is your body’s way of trying to help you survive because the body perceives stress and lack of sleep as a threat.
This is why deep restful sleep is necessary. Excess cortisol leads to binge eating and encourages your body to store fat.
A good sleep aid and thermogenic fat burner can help you get the sleep you need to get your cortisol at an optimal level.
Some of these nighttime formulas even contain cortisol lowering ingredients to keep your levels in line.
Fat Burning, Cortisol Lowering and Sleep Promoting Ingredients
Sleep Aids
- Ashwagandha: This ingredient helps both sleep and fat loss. It relieves anxiety and insomnia. Also decreases cortisol which helps you sleep and prevents your body from storing fat. Aids in reducing weight and fat mass.
- Chamomile – Apigenin: Apigenin is found in high concentrations in Chamomile and is an anxiety reducing and sedating bioflavonoid.
- L-Theanine: An amino acid that promotes relaxation.
