Try to get out of the house as often as possible when you are on a diet. It is important for your body to get fresh air, which will help to reduce stress and anxiety. Also, when you are out of the house, this will reduce your temptation to eat.
Make sure that you eat a breakfast if you are trying to lose weight. When you skip breakfast, your body will remain in a hibernation mode that doesn't burn calories well. This mode begins when you are sleeping and can be avoided by having a quick breakfast every morning. The breakfast will ready your body to burn calories for the day.
Reevaluate your weight loss goals on a regular basis. If your goals are unclear or abstract, you may end up giving up on them. Revisit your goals daily and make sure they are achievable in a reasonable manner. Expecting to lose 30 lbs in 2 weeks is irresponsible and will keep you from reaching reasonable goals.
