Let's be honest, pretty much every diet is so strict that it becomes difficult for most people to follow. Diets tend to 'dictate' and limit your food choices, what you are allowed to eat and what you are not. You may lose weight fast at the start but keeping it off and sticking to your diet most likely won't last. You may be able to do well with the diets on the first few weeks but eventually, you will find yourself 'cheating' here and there and that's when the problems start.
The best way to lose weight is to eat your favorite foods moderately, meaning eat a smaller portion. Though you may not lose weight as quickly as you want, it is the safest way to shed off your extra pounds. It's a really simple approach but is far from being easy.
