Starving yourself is a good way to lose weight. CMV.

There is an increasing rate of obesity in the country and in the world met by the amount of unhealthy food. In America, at least, there are high obesity rates but a high amount of fast food chains, eating healthy requires extra time, dedication and money. The current problem with weight in America has left a negative effect on mental health and self-esteem. A good weight is not the key to happiness but a bad way can easily lead the opposite way. Exercise is a huge contributor to good health and weight loss and should be encouraged. Of course diet is the other factor in losing weight, calorie intake vs. calories lost. But given the nutrition facts of 95% of food, it is harder to eat healthy when smaller portions of food have much more calories. Eating as little as possible is the cheapest and simplest way to lose weight. 

Edit: Thank you everyone! I have been sustaining one meal a day (about 500 calories) and HAVE noticed increased irritability and lower energy. I would not recommend it at all but noticing weight loss every few days seems like something that would only happen in my dreams.

Severe calorie reduction is actually one of the most difficult ways to lose weight. You will be feeling constantly hungry; overcoming that takes immense willpower. Cutting down on sugar and exercising regularly is not easy, but it's far easier.
