Will exercise kill my appetite?

Hard exercise may temporarily kill your appetite, but hunger will catch up with you within one to two hours. Temperature control regulates appetite to some extent. Therefore, if you feel hot after a hard workout, you may experience a temporary drop in appetite. But if you’re chilled, such as after swimming, you may feel ravenous.


The effect of exercise on appetite varies according to gender. Regularly exercising male rats tend to lose their appetite and drop weight, whereas female rats get a bigger appetite, eat more, and maintain their weight (Staten 1991). Human studies suggest that exercise makes food more attractive to women (Pomerleau et al. 2004). Read More

The hormone ‘lock and key’ theory

Our hormonal (endocrine) system is used to maintain homeostasis throughout the body. It’s sole purpose as a whole is to maintain the body’s natural internal environment. How the hormonal system works comes from the ‘lock and key’ theory.


Hormones can affect multiple tissues in the body, but they will not normally affect every single tissue in the body. This limitation is explained by the lock and key theory, which states that certain cells have certain receptor sites on them. Read More

Does the Fasting Diet work?

Some people resort to an extreme method of weight loss, which is fasting. We are not writing this blog to state whether fasting is right or wrong, but just an honest opinion. Contemplating fasting for religious or moral reasons is beyond our scope, but fasting for weight loss reasons is generally not recommended for personal training clients.


Of course, a person cannot fast forever, and fasting doesn’t teach a person how to eat. Fasting however does allow fat to burn, but it also causes a significant loss of muscle tissue and other lean mass. It can cause a loss of electrolytes and a decrease is blood pressure. The metabolism can slow, and if fasting continues for a long time, it can produce acidosis. Read More

How does skeletal muscle change during a resistance training phase?

When following a quality resistance training programme we all know that it will result in our muscles adapting, whether a change in diameter or strength. But what actually happens on a more in depth level within the muscle that causes these changes? We have broken this down for you here in our latest blog!


Resistance training results in adaptations in muscles, tendons and ligaments. The most obvious adaptation in skeletal muscle is hypertrophy, that is, an increase in muscle size (cross sectional area and volume). Resistance training results in an increase in cross sectional area of both type 1 and type 2 muscle fibers. However, type 2 fibers typically show a greater degree of hypertrophy than the type 1 muscle fibers and suffer great atrophy following periods of rest. It is also shown that type 2 muscle fibres are found primarily towards the surface of the muscle, giving that hard grainy look to a muscle. Read More

What is a DEXA scan?

A DEXA scan or DEXA imagining is known and given the label of the most accurate way to measure your body fat percentage. DEXA stands for ‘dual-energy X-ray absorptiometry’. But what is a DEXA scan?


When getting a DEXA scan a computer scans the body and takes pictures of the insides, similar to that of an MRI scan. It then puts all the pictures together and estimates how much body fat the subject has. Read More
