A 2011 study published in the Journal of Applied Social Psychology suggests that contrary to caffeine-junkie beliefs, coffee can actually deflate your confidence and focus in high pressure.
A typical 8oz (240 ml) cup of coffee contains :
- Vitamin B2 (Riboflavin) : 11% of the RDA.
- Vitamin B5 (Pantothenic Acid) : 6% of the RDA
- Vitamin B1 (Thiamin) : 2% of the RDA.
- Vitamin B3 (Niacin) : 2% of the RDA.
- Folate : 1% of the RDA.
- Manganese : 3% of the RDA.
- Potassium : 3% of the RDA.
- Magnesium : 2% of the RDA.
- Phosphorus : 1% of the RDA.
Did you know that caffeine is found in almost every commercial fat burning supplement?
There’s a good reason for that… caffeine is one of the very few natural substances that have actually been proven to aid fat burning.
Several studies show that caffeine can boost the metabolic rate by 3-11% (10, 11).
Other studies show that caffeine can specifically increase the burning of fat, by as much as 10% in obese individuals and 29% in lean people (12, 13).
Advantages of Coffee:-
- Help you lose weight: Coffee contains magnesium and potassium, which helps the human body use insulin, regulating blood sugar levels and reducing your craving for sugary treats and snacks.
- Burns your fat: Caffeine helps fat cells break down body fat and use it as fuel for training.
- Improves focus: Moderate caffeine intake, 1-6 cups a day, helps you focus and improves your mental alertness.
- Boosts physical performance: Have a cup of black coffee about an hour before workout and your performance can improve by 11-12%. Caffeine increases adrenaline levels in your blood. Adrenaline is your body’s “fight or flight” hormone which helps you to prepare for physical exertion.
- Reduces risk of cancers: One study has shown that coffee may decrease the risk of developing prostate cancer in men by 20 %, and endometrial cancer in women by 25 %. People in the test group drank four cups of coffee a day. Caffeine may also prevent developing of basal cell carcinoma, the most common type of skin cancer.
- Protects your body: Coffee contains a lot of antioxidants, that work as little warriors fighting and protecting against free radicals within your body.
- May lower risk of Type II diabetes: Caffeine decreases your insulin sensitivity and impairs glucose tolerance, therefore reduces your risk of type 2 diabetes.
Disadvantages of Coffee:-
- Can kill you: Yes, if you drink 80-100 cups (23 litres) in a short session. This dose is lethal and will amount in 10-13 grams of caffeine within your body. Before you reach this point, however, you’ll be vomiting most of it out since 23 litres of any liquid is a lot. Even drinking 23 litres of water can kill you.
- Can cause insomnia and restlessness. Again, it’s the caffeine working here. Your recommended maximum amount of caffeine is 400 milligrams, roughly the amount that you’ll get from 4 cups of coffee. If you’re caffeine-sensitive, be careful with coffee. You are probably already aware what amount and what kind of coffee suits, or doesn’t suit you.
- Can be toxic. Bad quality coffee can have a lot of impurities in it, which can cause sickness, headache or a general bad feeling.
