The problem with quick-fix diets
Quick-fix diets are usually short-term with a rigid set of rules. While you may lose weight, the diets are often too constraining to sustain for long. They're also likely to be nutritionally inadequate, could lead to problems such as iron deficiency or poor bone health and don't help you to address your real obstacles to losing weight and keeping it off. And, as I have found with so many people, they can make you lose confidence in your ability to slim successfully.
Stay active
Being more active in daily life helps to boost your mood and self-esteem, regulate (not increase) appetite, maintain muscle and make long-term success more likely.
Be realistic
Expecting more from your weight-loss programme than is really feasible only sets you up for failure, so be realistic about how much weight you'll lose and how quickly. Developing skills to achieve the lifestyle changes needed to reach your realistic goals is the safe and sensible approach.
