How fast should you lose weight?
I know it’s tempting to lose weight as fast as possible – but what’s the point, if you put it straight back on again? Losing weight gradually and healthily is the best way to ensure you maintain your goal weight when you reach it.
If you need to lose more than 50lbs in total, 2 lbs per week is a realistic, healthy and maintainable weight loss rate to aim for.
If you need to lose between 20 and 50lbs in total, 1 lb per week is a realistic, healthy and maintainable weight loss rate to aim for.
If you need to lose less than 20lbs, 0.5lb per week is a realistic, healthy and maintainable weight loss rate to aim for.

A Word About Motivation
We know that if you eat fewer calories than you burn, you will lose weight. So why is it so tough to stick to it?
I think it’s in part due to the society we live in, where unhealthy food is constantly available and selling it to us is big business. When delicious food is always easily accessible, it’s really difficult to know when to stop eating, and very easy to eat due to boredom, stress, habit, or just because it’s there.
Additionally, our bodies didn’t evolve to make losing weight easy. Your body is designed to store fat for fuel in case there’s a famine around the corner, and will only use those fat reserves when there isn’t sufficient food available. This is part of the reason why sticking to a diet is so difficult – you feel physical hunger, and every natural impulse tells you to go eat something, despite the fact that you may be unhealthily overweight.
Fortunately, you have a brain as well as a body, and you have the power right now to control what you eat and thereby determine what you weigh.
This is a really complex topic (and one I’m probably not qualified to discuss in depth) so I’m going to recommend a book instead. This is the only book (and I have read plenty) that had a real impact on my ability to control my eating, and thereby my weight. It’s not a fad diet, just a way of thinking that makes it easier to choose to eat a lot less, without feeling deprived. This combined with an awareness of how much my body needs (I like to know the numbers, hence this calculator!) really puts you in control.
