Most Jason Vale juices land around 125–150 calories per serving, with thicker avocado blends closer to ~250 calories per 420 ml glass.
If you’re following a Jason Vale plan or just making one of his blends at home, you’ll want a straight answer on calories. The recipes vary by produce and portion, but his fasting-day formulas are designed to be light, while thicker smoothies are deliberately higher. Below you’ll find reliable ranges, why the numbers differ, and simple ways to size your glass without getting lost in math.
How Many Calories In Jason Vale Juices? By Plan Type
For Jason Vale’s 5:2 Juice Diet, the juices in the plan are calculated so that each serving is roughly 125–150 calories; the book sample explains that this meets a daily target of about 500 calories for women and 600 for men on fasting days. It also notes that a 420 ml vegetable-based juice comes in around 150 calories, while an avocado smoothie of the same size is closer to ~250 calories.
Those ranges come from the plan design, not guesswork. Fruit-forward mixes push the total up because fruit juice carries more natural sugar per ounce than most green juices. For reference, a standard cup (240 ml) of orange juice sits near 110–112 calories, which scales to roughly ~195 calories at 420 ml.
Jason Vale Juice Styles And Typical Calories (First Look)
The quick table below gives you broad, evidence-based ranges by style and portion. Use it to estimate any similar recipe you make from his books or app.
| Juice Or Blend Style | Typical Portion | Estimated Calories |
|---|---|---|
| 5:2 Plan Juice (per serving) | ~1 glass | ~125–150 kcal (per book sample). |
| Vegetable-Based Green Juice | ~420 ml | ~150 kcal (plan guidance). |
| Avocado Smoothie (Thicker Blend) | ~420 ml | ~250 kcal (plan guidance). |
| Orange-Heavy Fruit Juice | ~420 ml | ~195 kcal (scaled from 112 kcal per 240 ml). |
| Apple-Heavy Fruit Juice | ~420 ml | ~190–205 kcal (47 kcal per 100 g baseline). |
| Apple Juice (Small Cup) | 4 oz / 125 g | ~60 kcal (USDA child nutrition spec). |
| Jason Vale “Juice In A Bar” (Snack Bar) | 1 bar | ~228 kcal (label databases). |
| Citrus-Green Mix (Citrus + Greens) | ~420 ml | ~160–200 kcal (citrus baseline + greens). |
Why Ranges Vary Across Jason Vale Juices
Produce Mix And Density
Swap in more fruit and the total climbs; lean into cucumber, celery, and leafy greens and it drops. That’s why a vegetable-heavy 420 ml glass sits near ~150 kcal, while fruit-forward pours creep toward ~200 kcal at the same volume.
Blended Vs. Juiced
Jason’s “thick” blends often add banana or avocado. The book sample flags these as higher energy options; it even advises avoiding yogurt/banana/avocado on strict fasting days to keep totals inside the 5:2 target.
Portion Size
Most of his glasses sit around 400–450 ml. If your juicer yields more, you’ll add calories in direct proportion. A handy anchor: orange juice sits near ~112 calories per 240 ml; so 300 ml is about ~140 calories, and 420 ml is near ~195.

You don’t need a lab to get a respectable estimate. Match your glass to a reference and scale.
Use The 5:2 Anchors When Your Recipe Looks “Green”
If your mix is mostly greens with a single sweet fruit, treat it as ~150 kcal per 420 ml. That’s the plan’s own benchmark for vegetable-based juices.
Scale From Orange Or Apple Juice For Fruit-Forward Mixes
- Orange juice: ~112 kcal per 240 ml.
- Apple juice: ~47 kcal per 100 g, which translates to ~110 kcal per 240 ml.
Blend those baselines with your greens and you’ll land in the right zone without overthinking it.
When You Add Avocado
Expect about ~250 kcal per 420 ml glass based on the plan’s own comparison. That’s still modest for a meal-like smoothie, but it’s not a fasting-day pick.
How The 5:2 Juice Diet Sets Daily Calorie Targets
The 5:2 schedule uses two low-energy days each week. The book sample explains the typical targets and shows that each fasting-day juice is pre-calculated to fit the daily cap. It states ~500 calories per day for women and ~600 for men, met with four light juices at ~125–150 calories each.
That setup is why many Jason Vale recipes feel lighter than café smoothies. It’s also why thicker blends are marked out as higher energy. If you’re on a strict 5:2 week, choose the lighter list for the two reduced-calorie days. For a regular day, a thicker smoothie can be a sensible bridge between meals.
Second Look: Sample Day Totals Across Common Approaches
These scenarios help you plan a day without a calculator. They use the plan’s stated ranges and standard juice baselines.
| Approach | Servings | Estimated Daily Calories |
|---|---|---|
| 5:2 Fasting Day (Plan Juices) | 4 × ~125–150 kcal | ~500–600 kcal. |
| Vegetable-Forward Day | 4 × ~150 kcal | ~600 kcal. |
| Citrus-Heavy Day | 4 × ~195 kcal (420 ml) | ~780 kcal. |
| Avocado Smoothie-Heavy Day | 3 × ~250 kcal (420 ml) | ~750 kcal. |
| Mixed Day (2 Green, 1 Citrus, 1 Smoothie) | ~150 + ~150 + ~195 + ~250 | ~745 kcal. |
Practical Ways To Keep Your Glass On Target
Pick The Right Base
Want a lighter pour? Use cucumber, celery, spinach, lemon, and one apple or orange for sweetness. That mirrors the plan’s vegetable-based anchor near ~150 kcal per 420 ml.
Measure By Volume, Not Guess
Pour your juice into a measuring jug before serving. If you’re at 300 ml, scale the reference numbers down; if you’re over 500 ml, split it in two. Orange juice’s 112-per-cup benchmark is handy for quick math.
Flag The “Thick” Add-Ins
Avocado pushes a glass into meal-replacement territory; the plan cites ~250 kcal for a 420 ml smoothie. Banana and yogurt do the same, which is why they’re skipped on strict fasting days.
Evidence Backing The Numbers
To keep you on solid ground, the ranges above come from two places: (1) Jason Vale’s own 5:2 Juice Diet sample pages, which specify per-juice ranges and daily caps, and (2) standard nutrition datasets for common juices so you can scale by volume. You can check the 5:2 Juice Diet sample for the per-drink and daily targets (including the ~150 kcal vegetable-juice and ~250 kcal avocado-smoothie benchmarks).
For orange juice, a reliable baseline is ~112 calories per 240 ml from MyFoodData’s USDA-sourced profile. For apple juice, USDA figures place it near ~47 calories per 100 g, and a 4-ounce school cup sits around 60 calories; both help you scale fruit-forward mixes cleanly.
FAQ-Style Clarity, Without The FAQ Section
Do Jason Vale Juices Ever Exceed 250 Calories?
Yes, if you blend thick add-ins like avocado or use large volumes of fruit juice in a single glass. The plan cites ~250 for an avocado smoothie at 420 ml; larger pours or extra fruit can nudge higher.
Can You Log A Jason Vale Snack Bar Alongside Juices?
If you’re tracking energy intake, the “Juice in a Bar” products listed in nutrition databases are ~228 calories each. That’s closer to a snack than a drink and should be counted separately.
What If Your Produce Sizes Differ?
The book sample reminds readers that produce size will shift totals slightly. If you stick to the lighter, vegetable-led templates, you’ll still hit the intended range per glass on fasting days.
Bottom Line On How Many Calories In Jason Vale Juices?
The plan’s own guidance gives you trustworthy anchors: around 125–150 calories for a standard serving on 5:2 fasting days, ~150 for a 420 ml vegetable-based glass, and ~250 for an avocado smoothie of the same size. Use the orange and apple juice baselines to scale fruit-forward mixes by volume, and you’ll keep your daily totals on track without micromanaging every ingredient.
