Whenever you have coffee do you want a little something sweet? Robbie says that’s because coffee is known to increase the blood glucose levels. In a recent study it increased the blood glucose levels of the participants by 50% when they had it as soon as they got up in the morning before breakfast. That’s not a good thing if you are trying to lose weight. She says what you should do is make sure that you have breakfast first.
Every cup of coffee dehydrates you, so if you are drinking half of your body weight in ounces of water per day minimum like Robbie suggests then for every cup of coffee or caffeine you drink you need to add another glass of water (8oz).
