Good find. Note, lifted from artikill: "...There is no reason to avoid tea and coffee, it's just about not having too much..." and... "Really what is of concern is the volume of coffee that people drink..." and..." Excess caffeine is associated with sleep disorders, headaches, heart palpitations and even anxiety...." If people drink standard sized milk (espresso type) coffee in moderation, say no more than 2 to 3 a day, there shouldnt be a problem using our normal milk but very often, it simply comes down to what people are used to. If you give someone used to drinking normal milk, a skinny milk, it will taste like water and vice versa, if you give someone used to skinny milk, normal milk instead, they wont be able to drink it. That has nothing to do with the number of calories, just the character of the milk on your palate and how you will feel as a result... As usual, its all about simple moderation. Additionally, people with milk intolerances should of course drink black coffee OR...people genuinely worried about the effect of milk fat in their diet could also consider black coffee... To many of us the story is nothing more than a rehash of information we already live by, however it is a good thing to put it out there occasionally and remind people. The easiest example of people that should be reminded, is the group if (usually) office workers that drink tens of instant coffees a day which is an extreme situation in terms of caffeine intake, and nothing to do with drinking "espresso/ cappuccino/latte" type drinks. My opinion for what its worth in terms of your question: "...Does using 'fat' milk vs skinny really make that much difference to your weight? - interested to know if anyone has a view on this, particularly perhaps anyone who's owned their own cafe...?" I think it shouldnt in the case of people drinking standard coffees in moderation...(assuming your question can be taken entirely on face value and doesnt include those that need to eliminate as much cholesterol as possible for heart / arterial conditions etc...although I imagine they would probably be on black coffee anyway...)
