Nutrition and Calorie Tips

Why diets work…

Why diets work… 🥗

There are lots of diets out there that claim to be better than any other. But what do ALL these diets have in common? And why do they work?

It’s nothing to do with any special properties of specific diets. For ANY diet to work it has to result in a calorie deficit. For some people certain diets will enable them to achieve this more easily and therefore that diet will work for them. But behind these diets are the simple maths of calories in vs out. However the issue with many diets is that they don’t educate you on the mechanism behind them and are therefore short term fixes.

Keto / low carb : omits or reduces carbs, which may reduce calories.

5:2 : limits calorie intake for 2 days a week, which may create a calorie deficit on average.

Intermittent fasting/ 16:8 : restricts the window of time you can eat in, which MAY reduce calories.

Diet clubs : assign points or values to certain foods and restrict food types, so MAY reduce calories

Shakes / Supplements : replaces meals or promotes excessive bowel movements etc which result in water loss, and a possible calorie deficit from meal replacement.

Juice cleanse/ detox : replaces whole foods with juices, resulting in fewer calories and rapid initial water loss.

Body type/blood type diet : restricts foods based on blood or body type, which may result in a calorie deficit

Spot the similarities? Many involve omitting food groups which will result in a calorie deficit. Calories can’t tell the time so methods involving not eating on certain days/times only work if you don’t overeat on others. Diet clubs help with accountability (regular weigh ins and rewards) but hide calories behind points or labels which lock you in to their method.

All of these diets can result in fat loss, but how many of them are sustainable long term, educate you on managing energy intake or build new habits? Some are actually damaging; laxative supplements and fasting can cause bowel damage, kidney damage and development of silent acid reflux etc, as well as promoting disordered eating.

So it doesn’t matter which ‘diet’ you choose, as long as it works for you – but make sure you understand WHY it works 🙂
