Intermittent fasting diet is all about eating your meals within a shorter time frame. It reduces your eating window to about 8 hours. Most diets achieve weight loss through the same process- a reduction in total daily calories consumed in relation to the calories needed to maintain your weight and intermittent fasting does the same thing. According to dietitian Robbie Clark, “intermittent fasting is safe when performed properly, and can change the function of cells, genes and hormones – and is therefore beneficial for weight loss and disease prevention.” The reason Clark gives, is that fasting provides our bodies with an opportunity to “initiate important cellular repair processes, and change hormone levels, which makes stored body fat more accessible – for energy and to burn,”. The positive changes that occur when you fast are:
- When you don’t eat for a while, your body initiates important cellular repair processes and changes hormone levels to make stored body fat more accessible. There is a significant drop of insulin in the blood which improves blood glucose control. This facilitates fat loss and balances the levels of the human growth hormone increases in the blood, which promotes fat burning and muscle growth. It also gives the body a chance to remove waste products from cells.
- By eating fewer meals hormone function is enhanced and facilitates weight loss. Short-term fasting actually increases your metabolic rate, helping you burn even more calories.
- Reduces the risk of type 2 Diabetes and cardiovascular disease by decreasing triglyceride and LDL cholesterol levels.
- By reducing oxidative stress and inflammation in the body it can prevent many common diseases. Oxidative stress is one of the major causes of premature aging and many chronic diseases. Intermittent fasting enhances the body’s resistance to oxidative stress and fights inflammation.
- Studies in rats have shown that intermittent fasting might increase the growth of new nerve cells that benefit the function of brain.
- Intermittent fasting might extend your lifespan similar to continuous calorie restriction.
