Hunger Hormones
Binge Eating and Appetite Signals
Binge eating is distinct from ordinary overeating, with its own recognisable pattern and appetite signalling disruption....
"I'm addicted to sugar" is one of the most common self-descriptions in weight loss, and the science behind it is genuinely contested.
What is not contested is that the craving is real and that several identifiable things make it worse. Those are more useful to address than the label.
What the evidence supports
Sugar activates reward pathways. Eating sweet food releases dopamine in the same brain circuits involved in other rewarding behaviours. This is well established.
Sweetness preference is innate. Human infants prefer sweet tastes, which likely reflects that sweetness historically signalled safe, energy-dense food.
Highly processed combinations are engineered to be compelling. Products combining sugar, fat and salt in specific ratios are more difficult to stop eating than any single component. That is a design outcome, not an accident.
What is debated
Whether this constitutes addiction in the clinical sense is genuinely disputed among researchers.
Arguments for: cravings, loss of control, continued use despite negative consequences, and reward pathway involvement all resemble addiction patterns.
Arguments against: much of the evidence comes from rodent studies using intermittent access schedules that do not mirror human eating. Tolerance and physical withdrawal, central to substance dependence, are not clearly demonstrated for sugar in humans. And people rarely binge on plain sugar. They binge on combinations of sugar and fat, which suggests the palatability of the whole food rather than the sugar itself.
The reasonable position is that sugar is highly rewarding and easy to overconsume, and that whether the word addiction applies is a debate about definitions rather than about whether the experience is real.
What frequently gets mislabelled
Much of what people call sugar addiction has a simpler explanation.
Blood sugar swings. A large refined-carbohydrate load produces a rapid glucose rise, a large insulin response, and a drop one to two hours later. That drop drives an urgent desire for quick energy, which feels exactly like craving.
This is the most common explanation and it is entirely mechanical.
Inadequate protein. A meta-analysis on protein and appetite hormones found protein decreases ghrelin and raises GLP-1 and cholecystokinin. Meals low in protein leave you hungry sooner, and hunger preferentially seeks quick energy.
Under-eating. Severe restriction reliably increases food preoccupation, particularly for energy-dense food. That is a normal physiological response rather than an addiction.
Poor sleep. Short sleep raises ghrelin, lowers leptin and specifically increases preference for sweet and energy-dense food.
Habit and cue. Chai with something sweet, three times a day, for years. That is a conditioned pattern, and it responds to different management than a craving does.
Emotional trigger. Covered in our guide to emotional eating, where the driver is feeling rather than energy need.
Why elimination usually fails
The instinctive response is to cut sugar entirely, and it frequently backfires.
Deprivation increases preoccupation. Forbidding a food reliably increases thinking about it.
Rule-breaking triggers abandonment. Someone who has eliminated sugar and then eats one mithai frequently concludes the attempt has failed and eats considerably more.
It is impractical in this context. Sweet chai, mithai at every occasion, and desserts at family gatherings are woven into social life here. A plan requiring total avoidance collides with normal life repeatedly.
Reduction survives where elimination does not.
What actually reduces cravings
Eat protein at every meal. This addresses the most common mechanical cause. Target roughly 1.2 to 1.6 g per kg body weight daily, with 25 to 30 g at each main meal. Eggs, dahi, daal, chana and chicken.
Eat protein and vegetables before carbohydrate. This flattens the glucose rise using exactly the same meal, which reduces the subsequent drop that drives craving.
Cut liquid sugar first. Sweet chai, bottled drinks, packaged juice and sweetened lassi deliver sugar with almost no fullness. This is the highest-value single change and it is easier than giving up food.
Reducing chai sugar from three spoons to one, across several cups a day, is substantial. Most people adapt within two weeks.
Do not skip meals. Skipping produces a larger drop later and stronger craving.
Sleep. Short sleep specifically increases sweet preference.
Keep it out of reach. Availability drives consumption more than intention does.
Allow a planned amount. A defined small portion, eaten deliberately, works better for most people than absolute prohibition followed by a large unplanned quantity.
The withdrawal question
Some people report headache, irritability and fatigue in the first days of reducing sugar substantially.
Whether that constitutes withdrawal in a pharmacological sense is unclear. It is equally consistent with adjusting to different blood sugar patterns and with the discomfort of breaking a habit.
Either way it typically settles within a week or two, and knowing that in advance makes it easier to sit through.
The Pakistani context
Sugar consumption here is high, and much of it is liquid.
Chai with multiple spoons of sugar, consumed several times daily, is the single largest source for many households. Bottled drinks, packaged juice, Rooh Afza and sweetened lassi add to it. Mithai accompanies every occasion.
WHO's obesity fact sheet sets out the associated health risks, and the link to type 2 diabetes matters particularly given prevalence here.
The practical implication is that addressing liquid sugar alone removes a substantial share of intake without touching any food anyone would notice at the table.
Where appetite support fits
If cravings persist after protein, sleep, meal composition and liquid sugar have genuinely been addressed, the remaining explanation is appetite and reward signalling.
GLP-1 appetite support you hold under the tongue works on that pathway as a physician-reviewed sublingual supplement with physician review before dispatch. METASLIM™ is not a pharmaceutical GLP-1 receptor agonist.
Note the sequence. Protein, sleep and cutting liquid sugar are free and address the most common causes. Something that costs money is worth considering once those have been tried properly.
Our page on how GLP-1 support works explains the pathway, and why you are always hungry covers the other mechanical causes.
The summary
Sugar activates reward pathways, but whether it is addictive in the clinical sense is genuinely debated, partly because people binge on sugar-fat combinations rather than plain sugar.
Much of what feels like sugar addiction is blood sugar swings, inadequate protein, under-eating, poor sleep or conditioned habit.
Elimination frequently backfires, because deprivation increases preoccupation and rule-breaking triggers abandonment.
Cutting liquid sugar is the highest-value single change and is easier than giving up food.
Protein at every meal addresses the most common mechanical cause directly.
Reported withdrawal symptoms typically settle within one to two weeks.
