Doctor explains what really happens when you quit sugar as simulation shows impact it has

Sugar may be delicious, but you can have too much of a good thing

Sugar, that most wonderful of the white powders one can consume, is quite the moreish delicacy.

Trying to ditch the stuff is quite difficult since it's so delicious, but if you knew the impact it was having on your body that might change your mind, or at least convince you to stick with the attempt to reduce the amount you're having.

Sweet treats may be hard to beat, but if you don't want to eat defeat then you could try listening to Dr Eric Berg, a TikTokking doc whose words might shock.

According to him in the early stages your cravings will be turned right up as a body that has been getting lots of sugar suddenly isn't getting it, and your senses are tuned towards acquiring more of the addictive substance.

However, the doctor said that in time you'd be able to go longer without food as your body changes the way it burns energy.

“You're going to have a lot more energy, because now you're body's tapping into your fat reserves to produce its energy,” he explained.

Along with the initial cravings you'll experience some mood swings as your body isn't getting the regular triggers of dopamine that sugar causes, but if you 'were depressed or had anxiety' then Dr Berg reckons your mood could actually improve.

Once you get over the hump the doctor advised: “You're going to think better, and have more focus and concentration."

That's the mental impact of quitting sugar, the initial withdrawal symptoms and cravings followed by an improvement as you get on more of an even keel, but the doctor said there were physical changes you'd notice as well.

One of them is the point Dr Berg mentioned about having more energy because the body adapts to tap into the fat reserves, so you should be more energetic and may also lose weight.


“You’re going to notice that throughout your body, there’s going to be a lot less inflammation and pain,” the doctor added as he rattled through the benefits.

"You’re going to notice that your skin is just a lot better. It will have that healthy glow."

Too much sugar is indeed considered bad for your skin, with high sugar consumption seen as a contributing factor to the development of acne.

This is what'll happen if you go cold turkey and try to eliminate sugar from your diet at a single stroke, but it's probably better to gradually reduce your consumption and wind things down over time so you don't get hit all at once.

According to the NHS adults shouldn't be consuming more than 30g of free sugars in a day, that's the stuff added to food and drink as well as the naturally occurring sugars in things like fruit juices and honey.
