The Sweatier the Better? Does Sweating Equal Weight Loss?

Image
You've probably seen this in the gym - some poor soul putting themselves through torture, peddling their ass off on the spin bike wearing a tracksuit and hoodie in July; all in the pursuit off greater caloric burn and weight loss. Sadly in reality only one of these is actually achieved and it isn't even in the way most people would hope...


Does sweating more equate to more calories burned? In a word - No. The amount you sweat during a workout does not represent how many calories, or how much fat you are burning. Sweating is merely a sign that your body's core temperature is beginning to increase and your homeostatic mechanisms are kicking in to dissipate some of this excess heat. Neither is sweating a sign that you are necessarily working hard... For example most of us won't sweat a great deal during a heavy strength training session, but will perspire significantly more when doing some very low level continuous cardio. This is because we only produce heat when we are …

Too Much Sugar in Fruit?

Image
This topic comes from a conversation I had with a client last week about sugar intake and how if you are trying to lose weight it's something to pay attention to... They asked me "what about all the sugar in fruit? Isn't that bad for you?" Now this is a perfectly reasonable question as on the surface you would be correct in assuming that fruit does contain a large amount of sugar, however it's important to understand that not all sugars are created equal - Allow me to explain...


The sugar that is naturally contained within fruit is unrefined and has a low glycemic-index meaning that is broken down by your body slowly. Conversely, refined sugar i.e. cane sugar is broken down very rapidly causing a spike in insulin and blood sugar levels. When you consume large quantities of refined sugar throughout the day your blood sugar will be chronically elevated. This often leads to weight gain because your body has no choice but to store any more sugar that is digested as f…

Cancer Research's New Campaign is "Fat Shaming"

Image
The fat shaming police are at it again...



The charity Cancer Research has come under recent criticism over it's latest campaign highlighting the growing obesity epidemic in the country. Their crime? Stating that obesity has now overtaken smoking as the leading cause of bowel, kidney, ovarian and liver cancer. Billboards like the one below display the word obesity on a cigarette packet to make the point, but apparently these facts have upset some people.


My problem with this mentality is the prioritization of people's feelings over reality, because unless we face up to this issue nothing will be done about it. In truth the current obesity crisis is a symptom of the wider problem - people are making poor lifestyles choices i.e. sedentary behaviour and being greedy when it comes to food. Generally speaking people don't refrain from behaviours they enjoy unless there are severe consequences. I think most people would agree that cancer is a pretty bad outcome and so bringing it…
