Dangers of excessive weight loss

> Losing the kilos too quickly, through either crash dieting or speed exercising, can be detrimenta­l to your health in the long run, experts warned

- RACHEL HOSIE

NOWADAYS, we’re bombarded with supposed quick weight loss fixes, and this is the time of year when they peak. “Drop two dress sizes by Christmas!”; “Lose the festive bulge by NYE!”; “Squeeze into your LBD with a two-week blitz!”

To many, the prospect of dropping a dress size in a fortnight seems too good to resist – if you could slim down in time for a certain festive party in the near future, why wouldn’t you give it a try?

But crash diets are not good for your health and could lead to nutritiona­l deficienci­es, muscle loss and slower metabolism, according to leading Harley Street nutritioni­st Rhiannon Lambert.

What’s more, losing weight that quickly is not sustainabl­e, and you’ll almost definitely end up regaining everything you lost – studies have proven this to be true.

When you crash diet, as the name suggests, you end up crashing and giving up. It’s not sustainabl­e.

But if you lose fat gradually over time, you’ll develop skills for mindful eating, reset your habits, rebuild a healthy relationsh­ip with food and, ultimately, create a new balanced lifestyle for yourself.

“Increase fruit and vegetable intake, complex carbohydra­tes

Reduce consumptio­n of heavily processed and ready meals These products are typically rich in sugar and unhealthy fats that can increase body fat and may spike blood sugar levels leaving you hungry shortly after consumptio­n.

Eat a balanced diet Ensure each meal time benefits from a balanced plate made up of protein, complex carbohydra­tes and healthy fats along with vegetables and fruit.

This will set you with many health benefits as well as keep you fuller for longer and provide key energy.

Remember to rest Loss and lack of sleep can boost levels of ghrelin (the hunger hormone) and decrease secretion IT HAS not been a good year for 56-year-old Tony Tan. His business had suffered heavy losses, and his health has been affected in part due to the stress.

Tan had gastritis when he was younger. As an aspiring entreprene­ur, he survived on quick meals and cigarettes for many years.

However, two years ago, Tan started experienci­ng a pressing, burning feeling in his chest after meals. He was diagnosed with heartburn and started taking antacids.

However, things got worse and eating became a chore. His tummy would feel uncomforta­ble and swallowing was a struggle, as he would feel like that was something stuck in his throat.

The symptoms of heartburn and acid reflux lie with a pair of valves, situated by the opening of the stomach. Known as the lower oesophagea­l sphincter (LES), it is supposed to close after allowing food into the stomach.

For some people, however, the LES becomes weakened or damaged, allowing acid to escape back up into the oesophagus, leading to acid reflux.

Stomach acid has a pH close to battery acid. When it contacts the oesophagus and rises up into the of leptin (the hormone that keeps you full).

Therefore, lack of sleep can lead to significan­tly increased hunger.

Introduce workouts Resistance training is widely considered to be great f or growing muscle.

High intensity exercise is also very effective in burning calories during and long after any workout. – The Independen­t

different instead of simple carbohydra­tes, and decrease processed sugary foods,” suggests Lambert, whose forthcomin­g book Re-Nourish: A Simple Way to Eat Well will be released on Dec 28.

According to the experts, a healthy amount of weight to lose per week is 1kg.

However, if you’re working out and doing a lot of muscle-building exercise too, you may not see the number on the scales drop despite that fact that you may be burning fat because you’re building muscle at the same time.

The reason you often put weight back on after crash dieting is because what you’ve lost isn’t really fat at all.

“Through these [crash] diets, fast weight loss can happen, and usually more than 1kg can be lost in the first week,” Lambert explains.

“However, a lot of this ‘lost weight’ is actually water weight, which is due to the glycogen that is burnt for energy, as the restricted diet is not bringing in enough energy for the body, so it has to use its stores.”

So that’s why you’ll end up putting the weight back on again.

Weight loss aside though, dropping pounds too rapidly can damage your health.

For starters, you may develop nutritiona­l deficienci­es.

“When you decrease your calorie intake, nutritiona­l deficienci­es can arise, as less food means that important nutrients such as mineral and vitamins are decreased,” Lambert says.

“However, along with the nutritiona­l deficiency comes the effects of the deficiency.

For example, a lack of vitamin D, calcium and phosphorus can lead to weak and brittle bones.

Additional­ly, fatigue and anaemia can arise due to minimal iron and vitamin B12 in the diet.

If you consume a varied diet, you can avoid this.

Secondly, you may lose muscle mass. Most people want to lose fat when they think about losing weight, but with crash diets they often end up losing water and muscle.

“There’s a great deal of research demonstrat­ing a low calorie diet often results in more muscle loss, than a higher calorie diet,” Lambert explains.

“In the long run though, you actually want to reduce fat and increase muscle, which can take a while to gain.”

Your metabolism may slow down too. Your metabolism determines the number of calories you burn per day and factors such as age, gender and genes can influence the speed of your metabolism.

But losing weight too quickly can slow your metabolism, meaning you burn fewer calories a day.

“This slowed metabolism can be due to a loss of muscle, and a decrease in the thyroid hormone,” Lambert explains.

It may not make headlines, but at the end of the day, slow and steady fat loss is key to keeping the weight off, and not regaining everything you tried so hard to lose.

“Losing weight too fast may give some quick results, but they can lead to a damaged body both mentally and physically,” Lambert says. “In the long run, the weight will most likely increase back to the set point.” – The Independen­t
