No, eating raisins during the fasting window breaks intermittent fasting due to their calories and sugar; save them for your eating window.
Raisins are handy, sweet, and bite-size. During a fasting window though, even a small portion adds energy that ends the fast. If you follow a time-restricted plan or alternate-day pattern, dried fruit belongs in the eating window, not the fasting stretch. The good news: you can still fit raisins into a plan without slowing progress once the clock says you’re in the clear.
Eating Raisins While Time-Restricted Fasting: What Happens
A fasting window is a period with no energy coming in. Dried grapes are compact sources of sugar and calories, so even a small handful counts as food intake. That means the metabolic state you aim for during a fast—steady blood sugar, low insulin, fat mobilization—gets interrupted. If you want the classic fast to stay intact, skip raisins until the eating window opens.
How Many Calories And Sugars Are In Raisins?
Portion size changes everything. The nutrition below shows why those chewy bites don’t fit a fasting window. Use it to plan portions for your eating window.
| Portion | Calories (kcal) | Sugars (g) |
|---|---|---|
| Mini box (0.5 oz / ~14 g) | ~42 | ~9 |
| 1 oz (~28 g / ~60 raisins) | ~85 | ~17–18 |
| Small box (1.5 oz / ~43 g) | ~128–129 | ~25 |
| 100 g | ~299 | ~59 |
Those numbers are typical for plain, dark seedless raisins. Flavored or yogurt-coated versions run even higher. If you’re tracking carbs during your eating window, these figures help you keep portions reasonable.
What Breaks A Fast In Practice
With classic time-restricted fasting, the fasting stretch means no energy intake. That includes fruit and dried fruit. Some modified plans allow small calories on limited days, but that’s different from a strict fast. If your goal is a clean fast, anything with calories breaks it—raisins included.
Health systems and research groups describe fasting as alternating periods of eating and not eating. In simple terms: food and calorie-containing drinks wait until the eating window. That’s the lens to use here.
Does One Or Two Raisins Matter?
Portions this tiny won’t make or break a week, but they still break the fast. About 60 raisins weigh an ounce and land near 85 calories. Do the math: a single raisin sits around one to two calories. Even that counts as energy. If you’re keeping a strict window, save the first bite for later and lean on zero-calorie drinks until the timer ends.
Why Dried Fruit Interrupts The Fasted State
Raisins deliver quickly absorbed sugars. That’s helpful during workouts or hiking, but it ends the physiologic pause you’re aiming for during a fast. Even a small serving prompts digestion, nudges insulin, and pulls you out of the fasted groove you set up overnight.
Where Raisins Fit On Different Fasting Plans
Not all approaches set the same rules every day. Here’s how to place raisins without derailing your plan:
16:8 Or 14:10 Schedules
All solid food waits until the eating window. Use raisins inside meals or as part of a dessert plate with yogurt and nuts. Keep portions measured so you don’t stack extra calories by accident.
5:2 Or Modified Fast Days
On low-calorie days, some plans allow 400–600 kcal total. In that scenario, a mini box can fit, but it still eats into your daily allotment. Balance it with lean protein and high-volume vegetables on the same day.
Alternate-Day Approaches
On full fast days, raisins wait. On feast days, keep portions sensible and anchor them to meals, not grazing.
Fasting-Friendly Choices During The Window
When the goal is a clean window, pick items with no energy. Here are easy swaps until your timer ends:
- Water (plain or sparkling)
- Black coffee
- Unsweetened tea or herbal infusions
- Electrolyte water without sugars or calories
Keep additives out during the window. Milk, sugar, syrups, creamer, collagen, and flavored powders with calories all count as intake and break the fast.
How To Include Raisins Without Slowing Progress
You don’t need to ditch dried fruit altogether. Use it with intent inside the eating window.
Smart Portion Ideas
- Trail-mix style: 1–2 tablespoons of raisins mixed with roasted nuts and seeds for texture and fiber.
- Yogurt bowl: Plain Greek yogurt, cinnamon, and a small sprinkle of raisins for sweetness.
- Salad topper: Toss a spoonful into leafy greens with a protein and an olive-oil vinaigrette.
- Oatmeal add-in: Stir into oats during the eating window; add chopped nuts to slow the sugar rush.
Timing Tricks That Help
- Lead with protein: Eat protein and veggies first, then add a small sweet element like raisins.
- Measure once: Pre-portion a few snack baggies so a “handful” doesn’t quietly turn into a cup.
- Pair with movement: If you enjoy raisins solo, line them up near a walk or workout during your eating window.
Labels, Add-Ons, And Hidden Calories
Plain raisins are simple: just dried grapes. Watch flavored packs or chocolate/yogurt-coated versions; coatings add energy and sugar fast. Also watch blends like trail mixes where chocolate bits or candy sneak in. Read labels and weigh a portion the first time to calibrate your eye.
Zero-Calorie Drinks: What’s Safe During The Window
Plain water is always fine. Black coffee and unsweetened tea are fine for most fasting plans. The line gets crossed when milk, sweeteners with calories, syrups, or creamers show up. On tough mornings, a sprinkle of cinnamon or a squeeze of lemon zest can scratch the flavor itch without adding energy.
Table Of Common Picks During A Fast
Use this quick reference to keep your window clean.
| Item | Typical Calories | Breaks A Fast? |
|---|---|---|
| Water (plain/sparkling) | 0 | No |
| Black coffee | ~0–5 per cup | No (most plans) |
| Unsweetened tea/herbal | ~0 | No |
| Electrolyte tablet with sugar | 10–40 | Yes |
| Raisins, 1 oz | ~85 | Yes |
| Mixed nuts, 1 oz | ~160–180 | Yes |
Real-World Scenarios And Simple Fixes
Morning Coffee Habit
Keep it black until the window opens. If you miss the sweetness, set aside a pre-measured portion of raisins to stir into oatmeal at brunch instead.
Desk Snacking
Store zero-calorie drinks on your desk during the fasting stretch and move your raisin mix to a sealed container labeled for your eating window. Out of sight, out of mind works here.
Evening Cravings Near The Cutoff
If cravings hit near the end of the window, pour a short glass of sparkling water and delay. Then break the fast with a protein-anchored plate and a small sweet bite at the end.
Safety Notes For Special Populations
If you live with diabetes, take medications that lower blood sugar, or are pregnant, plans that include fasting windows need personal medical guidance. Dried fruit is dense in sugars and should be placed with care inside a broader meal plan. Use a glucose monitor and a registered dietitian’s plan if you need tighter control.

Practical Takeaway
During the fasting window, raisins are off the table because they bring energy. Inside the eating window, they can fit in small, planned portions paired with protein and fiber. Keep your window clean, keep portions measured, and you’ll keep your plan moving.
