People through their life-style and drug-abuse, decrease their immunity and create fertile grounds for these microorganisms. And people themselves act as the carriers and create conditions for their spread. Think of it this way – if there is no drug abuse, no sexual perversions, no promiscuity – what will be the rate of infection of HIV or Hepatitis-B? Extremely low. And that applies to most of the modern diseases in some way or the other. Bacteria and viruses cannot rage a war against us – it is us who help them kill us!
Sleep and meditation. Try to avoid high intensity exercising like running and weight-lifting. The more your body is working, the more energy you'll lose. Take the time to relax, stretch (keeps your blood circulation to better remove toxins), and use the time to reflect. Ask yourself why you're doing this, and empower your will to finish. Drink lots of water, nap, and go to bed early. Avoid watching TV because it'll disrupt your consciousness and make you hungry (due to all the food commercials).
Skip juice cleanses or liquid diets. A popular cleansing regimen for losing weight involves drinking only juice or another type of liquid for a few days to a week. This is dangerous because you could end up without essential nutrients. These extreme cleanses are also counterproductive because most people just gain back any weight they lost when they go back to eating normal food again. Doctors don't recommend any sort of diet like this, and say following a healthy diet and exercise routine is much better for losing weight.
