Trans fats raise levels of the 'bad' blood fats - LDL cholesterol and triglycerides - that contribute to hardening of the arteries and fire up inflammation, an immune-system response that's involved in the build-up of fatty plaque in artery walls.
They also lower the 'good' HDL cholesterol that could mop it all up, and add to the abdominal fat that is most associated with diabetes and heart disease. Consuming just 5g of trans fat a day may raise your risk of heart attack by 25 per cent.

Lustig explains that the consumption of these "food-like substances" leads to an increase in chronic insulin levels, the fat-making or energy-storing hormone. We are thus consuming empty calories, ie foods that not only provide no nutritional value but are quickly converted to fat. As we have not used these calories in a meaningful way, we feel hungry again and so the cycle continues.

Fast foods increase your risk for weight gain, obesity and development of type 2 diabetes. Research by Mark Pereira, Ph.D., published in "Lancet" in 2005 discovered that fast food consumption is strongly associated with weight gain and insulin resistance and an increased risk of obesity and type 2 diabetes, respectively. The research found that a person who consumes fast foods at least twice per week gains an extra 4.5 kg of body weight and has a two-fold greater increase in insulin resistance than a person who consumes fast foods less than once per week. Insulin resistance is the diminished ability for your cells to bind to insulin in your blood to reduce sugar levels.
