Better metabolic sensitivity

The effect of exercise on hunger cues has been researched for decades and all is not as obvious as it seems.

The effect of exercise on insulin sensitivity has been widely reported in scientific literature. Training increases insulin sensitivity leading to many positive health outcomes. One being better awareness of appetite and control of hunger. In short exercise helps to reduce hunger cues by improving regulation of blood sugar levels.

Exercise increases the secretion of GLP-1, PYY and pancreatic polypeptides after each meal. Normally the concentration of these substances in the body increases following a meal leading to reduced feeling of hunger. Exercising has been shown to produce more of these substances after each meal (Martins 2008). Furthermore exercise has been shown to increase the suppression of hunger hormone (ghrelin) after each meal (Martins 2010)

Regular training also helps to minimise future weight gain by:

1. Improving appetite control

2. Increasing insulin sensitivity (a good thing)

3. Reducing secretion of hunger hormone ghrelin

4. Reducing risk of stress-induced weight gain

5. Increased calorie expenditure

6. Increased aerobic fitness and muscle mass.

By training regularly your body responds better to the food you eat. You respond in a more sensitive (correct) way to your meals making you less likely to have a sugar slump or overeat at each meal. Adding to this the fact that training increases your calorie expenditure, and therefore fat mobilisation, and here is another reason to up your training this month.

With healthy wishes,
