Weighing yourself once or twice a week so you can track how you are doing will help you see how much and why your weight fluctuates up and down. If you cant face weighing yourself check your waist band.
You may be fat phobic think you shouldnt eat fat to lose the desired weight but your wrong. You need to eat some fat as it slows down digestion and keeps you fuller for longer. Include modest amounts of unsaturated fats like nuts and oils.
You are allowed a treat , eating in moderation is the main key to having a healthy nutrition and if you choose one night to enjoy a bottle of wine and a curry , it will make you feel you have to earn it making you work harder on the excercise and feel more rewarding .
Plan your meals so that you have a balanced time between meals and if you feel the need to snack make sure you have a handful of healthy treats at the ready for each day seperated into portions .
If you are soo strick you will end up bored and frustrated but having some flexibility in your plan means you will enjoy it more , dont feel you cant eat something you really want like a bar of chocolate you can !, just eat a portion of it at a time , you will find you enjoy it more anyway.
Dont excercise to the point it is the only thing you do, try excercising just a few times a week or just going for a run with a friend on the evening or early morning .
