Why Do You Crave Sugar Constantly?
TL;DR
Constant sugar cravings mean broken metabolism, not lack of willpower. Low thyroid, low blood sugar from poor meals, inadequate calories, or poor sleep cause cravings. Fix metabolism: eliminate PUFAs, support thyroid, eat adequate protein and carbs at meals, sleep 7-9 hours. Cravings disappear within 2-4 weeks. Not willpower issue. Metabolic issue.
You crave sugar constantly.
All day. Every day. Can't stop thinking about food.
You fight it. Use willpower. Feel guilty when you give in.
"Just need more discipline." "Sugar addiction." "Lack of self-control."
Wrong.
Your metabolism is broken. Body is screaming for energy.
Cravings are symptom, not cause.
Sugar cravings are like car fuel light flashing. Not lack of willpower. Engine needs fuel. Fix engine (metabolism), light turns off.
What Causes Sugar Cravings
1. Low Blood Sugar
Poor meal composition.
Meal with carbs but no protein/fat:
- Blood sugar spikes
- Insulin overcompensates
- Blood sugar crashes
- Brain panics, demands quick energy
- Intense sugar craving
Example: Breakfast: toast with jam (no protein, no fat)
- 10am: starving, craving sugar
Solution: Protein + fat + carbs at every meal. Blood sugar stable. No cravings.
2. Low Thyroid
Thyroid regulates energy production.
- Cells can't produce energy efficiently
- Body craves quick energy (sugar)
- Constant hunger despite eating
Fix thyroid, cravings disappear.
3. Inadequate Calories
Chronic under-eating.
Body needs energy:
Eating 1,200-1,500 calories: Body starving. Craves calorie-dense food (sugar).
Eat adequate calories. Cravings reduce.
4. Poor Sleep
Sleep deprivation increases hunger hormones.
Under 7 hours:
- Ghrelin increases (hunger hormone)
- Leptin decreases (satiety hormone)
- Crave sugar and carbs
Sleep 7-9 hours. Cravings reduce dramatically.
5. Stress
Chronic stress elevates cortisol.
- Increases blood sugar
- Then crashes blood sugar
- Brain craves sugar for quick energy
- Also comfort eating
Manage stress. Cravings reduce.
6. Not Eating Enough Protein
Protein increases satiety.
Low protein meals:
Adequate protein (1.2-1.6g per kg): Satisfied for 3-4 hours. Fewer cravings.
7. Restricting Carbs Too Much
Very low-carb diets increase cravings.
Why:
Eat adequate carbs (150-250g daily).
8. Habit and Reward Pathways
Sugar activates dopamine.
If eating sugar daily for years: Brain expects it. Cravings become habitual.
Break habit: 2-4 weeks without daily sugar. Neural pathways reset. Cravings fade.
How to Stop Cravings
Eliminate PUFAs
Primary intervention.
Metabolism heals. Cravings reduce naturally.
Balanced Meals
Every meal: Protein + fat + carbs
Example breakfast:
- 3 eggs (protein, fat)
- 2 slices toast with butter (carbs, fat)
- Fruit (carbs)
No cravings for 3-4 hours.
Bad breakfast:
- Toast with jam (carbs only)
- Craving sugar by 10am
Balance meals. Cravings disappear.
Adequate Protein
Every meal: 20-40g protein
Breakfast: 3 eggs = 21g Lunch: 6oz chicken = 42g Dinner: 6oz fish = 36g Total: ~100g
Eat Adequate Calories
Don't restrict.
- 2,000-2,500 calories (women)
- 2,500-3,000 calories (men)
- More if active
Chronic restriction causes cravings.
Adequate food eliminates cravings.
Eat Enough Carbs
150-250g daily.
Sleep 7-9 Hours
Critical for appetite regulation.
Poor sleep = intense cravings.
- Consistent schedule
- Dark, cool room
- Magnesium before bed
- No caffeine after noon
Sleep improves, cravings reduce.
Support Thyroid
Low thyroid causes constant hunger.
Thyroid improves, cravings disappear.
Manage Stress
Strategies:
- Meditation
- Walking
- Therapy
- Reduce work hours if possible
Break the Habit (2-4 Weeks)
If eating dessert daily: Neural pathways expect it.
Break cycle:
- 2-4 weeks without daily sugar
- Cravings fade significantly
- Can occasionally have dessert without intense cravings
First week is hardest.
Timeline for Craving Reduction
Week 1-2:
Week 2-4:
- Cravings significantly reduced
- No longer obsessing about sugar
- Can go hours without thinking about food
Month 2-3:
Month 3-6:
Most people see dramatic improvement within 2-4 weeks.
What About "Sugar Addiction"
Sugar isn't heroin.
Cravings feel intense because:
This isn't addiction.
This is starvation signal. Even when eating adequate food.
Fix metabolism: Cells produce energy efficiently. Brain doesn't panic. "Addiction" disappears.
You're not weak.
Can You Ever Eat Sugar Again
Yes.
After metabolism heals:
Key: Make it occasional. Not daily habit.
Example:
Fruit, honey, maple syrup better than candy.

After 6 weeks:
Example 3: Evening Cravings Fixed
Before:
After 2 weeks:
- Started eating adequate dinner

- Evening cravings disappeared
- Was under-eating all day
FAQ
Q: I crave sugar constantly. Is this normal? A: No. Sign of broken metabolism. Usually low thyroid, inadequate calories, or poor meal composition. Fix these, cravings disappear.
Q: How long until cravings stop? A: Most people see significant reduction within 2-4 weeks. If eating balanced meals, sleeping well, eliminating PUFAs. Full resolution 2-3 months.
Q: Am I addicted to sugar? A: Probably not. More likely broken metabolism. Low thyroid, low blood sugar, inadequate calories. Fix metabolism, "addiction" disappears.
Q: Should I go cold turkey on sugar? A: Better to fix underlying issues first. Eat balanced meals, adequate calories, support thyroid. Cravings reduce naturally. Then easy to cut back on sugar.
