It seems like you are ready to start a diet. That’s wonderful indeed. But you should definitely prepare for a diet. Remember that it would be stressful for you emotionally and physically. It takes much energy, time and effort. So keeping a diet is never easy. Think it over properly why you need it and what are the benefits of keeping a diet. You should plan your diet thoroughly. How much weight are you planning to lose? How long the diet would last? Spontaneity may ruin your plans and expectations from a diet. So your diet would be stressful but it shouldn’t be depressing. And remember that one should eat to live, not live to eat.
