Why Diet’s Don’t Work 12th November 2019

When we hear the word diet we often think of food deprivation, bland meals and unpleasant periods of semi-starvation – which it tends to be however this way of thinking is very unsustainable and unhealthy. People jump from diet to diet wondering why nothing works or why they bounce back to their original weight after each diet.  This is because diet’s don’t work.

Throughout this article you will learn how you can replace this way of thinking with a sustainable long-term healthy eating plan allowing you to eat normal foods without restricting yourself and learn the reasons why diets do not work.

Biochemical individuality:

There are many diets out there and each is said to be able to help every single one of us, which it can, but what they do not take into consideration is how we are all physiologically different and how all of our bodies need different foods and requirements. This may explain how you and your friend have both been following the same diet but she has managed to loose 10lbs and you only 2lbs.


Deprivation is used to describe a period of time when the body is starved or restricted from eating. This could be a fasting diet or a 5:2 diet. When a calorie restricted diet is followed over a prolonged period of time your body will go into famine mode and start to hold onto the calories that you eat and store body fat to use for energy later on as it is worried when it will get fed again.

During periods of starvation your body can also start eating into its own muscles for fuel (becoming catabolic). This is not a good thing and can be very detrimental and go against your actual goals.  Chronic under eating can also lead to other effects on the gut such as bloating as soon as you do eat. Bloating often happens at this time as your body has consumed food which it has not consumed for a while or of an increase in volume. Shocking the body like this is not sustainable.

Not sustainable:

A diet is often perceived as a quick fix and something you can dip in and out of when you want to lose weight for a certain event or time of year. People often also think diet can help you lose weight quick then when you go back to normal eating you will maintain. This however is not true as when normal eating commences at a higher volume weight gains happens pretty quickly.

Diets are unsustainable as they are not suitable to be followed over a prolonged period of time.

Diet foods:

Diet foods are one of the most confusing products on the market. Many of us have to come think that “diet foods” are the best and most effective way to lose weight. In fact they may even be hindering your weight loss progress as these low fat, fat free products are all highly refined and processed containing virtually no nutrients whatsoever, so aim to avoid these wherever possible or be assured to make sure that you check the label before buying it.

A great take away tip is – if you cannot pronounce or recognise any of the ingredients then you should not be eating them.

Weight gain:

The cycle of deprivation and then eating ‘normally’ again mentioned earlier can lead to weight gain and not weight loss, so you could become your own worst enemy. The most effective way to find a sustainable plan is to find real foods that are nutrient dense helping to keep you fuller for longer and aiding your body with all the vitamins and minerals it needs to function.

Promote unhealthy relationship with food:

Following a calorie-restricted diet and depriving yourself of foods which you deem to be bad can lead to an unhealthy relationship with food, leading to cycles of deprivation and binge eating. The most important point to take on board here is to focus on eating good fats, proteins and vegetables allowing nutrient dense foods to nourish your body, helping you to build a good relationship with proper food.

Damage metabolism:

When restricting calories your body will become stressed and a unfavourable hormonal environment can be created. Changes such as raised cortisol levels, thyroid dysfunction, impaired detoxification and altered energy production can make it much more difficult for you to burn fat and lose weight.

In conclusion

For all of the reasons above it is suggested that following a “diet” is not the best way to lose weight and become healthy, in fact following a sustainable life-long healthy eating programme is. Diet’s don’t work!

The most efficient change you can make is in experimenting and finding out what will work for you, eliminating any foods that cause you irritation and monitoring your calories in and calories out. Be sure to add in lots of protein, good fats, vegetables and salad. Don’t forget that you can also have treats, but in moderation.

Don’t turn your treat into a daily habit – it is not a treat then!
