- Pip Ahoy! We are coming to find you…!
Caffeine is one of those subjects that massively irritates me. It seems that people who don’t really have a clue normally have the strongest opinion about it.
Caffeine, in moderation, is NOT harmful – it has been shown to enhance mental and physical performance and reduces effort perception (1), not to mention the obvious decrease in fatigue.
Of course, like anything, if you overdo it you are going to have side effects, but as a vague guideline it is recommended that you do not consume more than 400mg a day (2) ( 4 cups of coffee) but this is still, as I said, vague. An important note here is that it is likely you will be recommended to avoid caffeine altogether if you are pregnant or have a certain heart problem (or in some anxiety cases) as it may ‘gee you up’ too much, but other than these cases you should be fine.
Why I bring the subject up of caffeine is that is a useful tool on a diet during energy slumps; you’ll be surprised how many times you think you are hungry when actually you are tired. Do you feel yourself reaching for the biscuits at about 4pm? This is because your body is fatiguing at this point and in order to keep itself awake it craves something that will give it an immediate energy hit, which it will get from refined carbohydrates such as biscuits. Ideally when you have this feeling you would rest, but let’s be realistic, in most cases you are not going to be able to have a nap at work! If you have a caffeine hit you should quickly find that your carb cravings are curbed. Caffeine has also been sent to increase your metabolic rate (3,4).
In my opinion this is why things like Forza raspberry ketones have some success with certain people – their high caffeine content pushes you through the afternoon and prevents cravings as well as keeping you more physically active. Caffeine is also constantly recommended as a supplement pre workout to increase mental and physical alertness – how many times have you not gone to the gym because you felt too tired?
Whilst I am not advising you to hammer four cups of coffee, do not listen to those that lecture you for having a cup!
