  • Caffeine in coffee and a related compound in tea called theobromine have direct effects in the brain and central nervous system.
  • Thought processes, heart rate, respiration, muscle co-ordination and mood are affected after just one cup of tea or coffee; effects take place within 15-25 minutes.
  • Caffeine increases the circulation of fatty acids. This is shown to enhance oxidation of these fuels.


  • Three or more cups of coffee can give you the jitters and muddle concentration and thinking. Though caffeine can temporarily sharpen reaction time and increase alertness, it can contribute to that mid-morning energy slump.
  • Coffee consumed with food can reduce absorption of mind-enhancing minerals e.g. iron and calcium by as much as 90%.
  • Caffeine can be excreted in breast milk.
  • Aside from the effects of caffeine, oils in coffee can cause gastrointestinal irritation and the tannin in tea may cause constipation.
  • Caffeine can exacerbate certain health conditions such as; ulcers, heartburn, and heart problems.

Can Caffeine Help You Lose Weight?

A number of studies have indicated that large amounts of coffee (we're talking at least six cups a day!) can slightly increase weight loss as part of a low fat, high exercise diet. But the weight loss is not permanent and caffeine alone has no effect on weight loss.

Caffeine will suppress your appetite, though this will only last for a very brief period, once again this will not affect your weight loss program. Caffeine is however a diuretic (it increases you urine output).

Tips For Kicking The Caffeine Habit

  • Gradually switch from regular to decaffeinated coffee by mixing them before brewing. Mix in a higher proportion of decaffeinated grounds each day.
  • When you feel yourself getting sleepy while studying, driving, or working: take a break, open a window, breathe deeply and stretch, jog in place, go for a walk, get a cold refreshing drink, or take a nap!
  • Drink plenty of caffeine-free liquids while you're quitting, such as water, herbal tea, club soda.
  • Drink from smaller cups instead of large mugs or glasses.

Herbal Teas; The Healthy Alternative.
