Lose weight naturally

Obesity is a medical condition which involves excess body fat accumulating to the extent that it has a negative effect on health. People are generally considered obese when their body mass index (BMI), a measurement obtained by dividing a person’s weight by the square of the person’s height, is over 30 kg/m2. In the UK, 20% of the population are classed as obese.

Overweight is defined as falling within the range of 25–30 kg/m2. While less serious than obesity, the impact on health is still harmful, especially if associated with other negative lifestyle factors such as a lack of exercise, high blood sugar, high cholesterol, low polyphenol intake, smoking and poor gut health. It affects 60% of the UK population, and this figure is increasing year by year. 40% of all cancers are thought to be linked to excess weight.

How does obesity increase health problems?

Direct biochemical mechanisms:

  • Oestrogen levels higher / Progesterone levels lower
  • Insulin resistance
  • Insulin-like growth factor receptor (IGF-1)
  • Higher leptin / lower adiponectin
  • Inflammation – Cox 2 overexpression

Indirect mechanisms:

  • More difficult to exercise due to shortness of breath and arthritis
  • Lower vitamin D levels

Benefits of exercising if overweight

Direct mechanisms – reducing risks (independent of weight loss):

  • Improves insulin sensitivity (Lowers IGF-1)
  • Lowers sex hormones
  • Enhances antioxidant enzyme production
  • Improves DNA repair P53 (BCRA 1&2 expression)
  • Epigenetics (telomere length, gene expression)
  • Anti-inflammatory (prostaglandin & COX-2)
  • Reduces cholesterol and saturated fats

Indirect mechanisms:

  • Helps individuals lose weight (10% after 6 months >3.5hrs/wk)
  • Reducing weight elevates mood
  • Increases light exposure and vitamin D – if exercising outside
  • Helps arthritis
