Quick Answer: Potatoes have the most calories of any vegetable, with around 77 calories per 100g (130 calories per medium potato). They’re packed with complex carbohydrates that give you sustained energy for your workouts and daily activities.
Why High Calorie Vegetables Matter for Your Goals
You might think vegetables are just for weight loss but some varieties give you serious energy and nutrients to fuel your training. High calorie vegetables provide complex carbs, healthy fats, and micronutrients that support muscle recovery and performance. And they’re way better than processed carbs because you get fiber, vitamins, and minerals alongside those calories.
If you’re looking to build muscle or maintain energy through intense training sessions, these calorie dense options should be part of your meal plan. They help you hit your macros without feeling overly full or bloated.
Potatoes Lead in Vegetable Calories
White potatoes contain around 77 calories per 100g while sweet potatoes have about 86 calories per 100g. The carbohydrate content (17–20g per 100g) provides glycogen for your muscles, which is exactly what you need before and after training.
How to use them: Eat 150–200g (1 medium potato) 2–3 hours before your workout for sustained energy. Roast them with olive oil or boil them and add to your post workout meal with lean protein. Track your portions because it’s easy to overeat when they taste this good.

Avocados Pack Healthy Fats and Calories
Avocados technically count as a fruit but most people treat them as vegetables in meals. They deliver about 160 calories per 100g, mostly from monounsaturated fats that support hormone production and nutrient absorption. These healthy fats help you feel satisfied and reduce inflammation after tough training sessions.
Action steps:
- Add half an avocado (80 calories) to your breakfast or lunch daily
- Use it as a recovery food alongside eggs and whole grains
- Spread it on toast or blend into smoothies for calorie dense nutrition
Corn Provides Quick Energy from Carbs
Sweet corn contains approximately 86 calories per 100g with a good balance of carbohydrates (19g) and fiber (2g). The starches break down relatively quickly, making corn useful for pre workout fuel or post session recovery.
Use fresh or frozen corn (canned often has added sodium). Add 100–150g to salads, stir fries, or eat it on the cob 90 minutes before training. Pair it with protein to balance blood sugar and maximize muscle protein synthesis.
Peas Deliver Protein and Calories Together
Green peas contain about 81 calories per 100g plus they provide around 5g of plant protein. This combination makes them excellent for vegetarians or anyone wanting to boost their protein intake from whole foods. The fiber content (5g per 100g) supports digestion and steady energy release.
Implementation: Include 150g of peas in your lunch or dinner 3–4 times per week. Mix them into rice dishes, add to soups, or eat them as a side with grilled chicken or fish.
Parsnips and Cassava for Variety
Parsnips give you 75 calories per 100g and cassava (yuca) provides around 160 calories per 100g. Both vegetables offer different flavor profiles and nutrient packages compared to regular potatoes. Cassava is popular in many international cuisines and provides resistant starch that feeds beneficial gut bacteria.
Roast parsnips with other root vegetables for 30–40 minutes at 200°C (400°F). For cassava, boil it until tender (20–30 minutes) and use it like you would potatoes in meals.
FAQ About High Calorie Vegetables
What vegetable has more calories than others?
Cassava and avocado top the list at 160 calories per 100g, followed closely by sweet potatoes at 86 calories. These vegetables provide substantially more energy than leafy greens or watery vegetables like cucumber (16 calories) and lettuce (15 calories). The calorie density comes from starches and healthy fats rather than sugars.
How many calories should vegetables provide in your diet?
Aim for vegetables to make up 20–30% of your total daily calories if you’re active and training regularly. For someone eating 2,500 calories per day, that’s 500–750 calories from vegetables. And you can split this between high calorie options (potatoes, corn) and low calorie nutrient dense choices (broccoli, spinach, capsicum) for balanced nutrition.
Do high calorie vegetables cause weight gain?
Only if you eat them in excess of your maintenance calories. High calorie vegetables provide quality nutrition and energy for training performance. Research shows whole food carbohydrates like potatoes support metabolic health better than processed alternatives. Track your total intake and portion sizes to stay aligned with your goals.
What’s better for building muscle: high calorie vegetables or supplements?
High calorie vegetables win because they provide carbohydrates for glycogen replenishment plus micronutrients like potassium, magnesium, and vitamin C that supplements lack. Potatoes contain more potassium than bananas (421mg vs 358mg per 100g), which supports muscle contraction and recovery. Use supplements to fill gaps but prioritize whole foods for sustainable results.
Can you eat too many calories from vegetables?
Technically yes but it’s difficult to overeat whole vegetables because of their fiber and water content. You’d need to consume massive portions of potatoes or corn to significantly exceed your calorie needs. Most people benefit from increasing vegetable intake rather than restricting it. Focus on variety and listen to your hunger cues.
Are cooked vegetables higher in calories than raw?
The cooking process doesn’t add calories unless you use oils, butter, or sauces. However, cooking concentrates vegetables by removing water, so 100g of cooked potato provides more calories than 100g of raw potato by volume. Roasting with 1 tablespoon of olive oil adds approximately 120 calories to your vegetable serving.
Which vegetables should athletes prioritize for performance?
Athletes should focus on starchy vegetables like potatoes, sweet potatoes, corn, and peas for carbohydrate loading before competitions or intense training blocks. Studies in sports nutrition show consuming 3–5g of carbs per kilogram of bodyweight optimizes glycogen stores. A 70kg athlete needs 210–350g of carbs, which translates to roughly 1–1.5kg of potatoes across the day.
Do organic vegetables have different calorie content?
No significant difference exists in calorie content between organic and conventional vegetables. The calorie level depends on the vegetable variety and growing conditions rather than farming method. Organic produce may contain slightly higher levels of certain antioxidants according to some research, but this doesn’t affect the macronutrient composition or energy density.
Building Your High Calorie Vegetable Strategy
Your approach to including these vegetables should match your training intensity and body composition goals. If you’re in a muscle building phase, aim for 200–300g of starchy vegetables per day split across 2–3 meals. And if you’re maintaining or in a mild deficit, reduce to 100–150g daily and increase lower calorie vegetable portions instead.
The timing matters for optimal performance. Consume your highest calorie vegetables 2–4 hours before training for sustained energy release. Post workout within 30–60 minutes, pair high calorie vegetables with lean protein to maximize recovery and muscle protein synthesis rates.
Don’t eliminate high calorie vegetables from your diet because of outdated fat loss myths. These whole foods provide the energy substrate your body needs to train hard and recover properly. Track your total daily intake rather than fearing individual foods.
Preparation methods influence absorption: Cooking potatoes and sweet potatoes increases their digestibility and glycemic response, making the carbohydrates more readily available for glycogen synthesis. For weight management goals, letting cooked potatoes cool creates resistant starch that reduces the calorie availability by up to 10–15%.
Combine these vegetables with healthy fats (olive oil, avocado) and quality proteins (chicken, fish, legumes) for complete meals that support your fitness objectives. The fiber content slows digestion and prevents blood sugar spikes that lead to energy crashes during training.
Next step: Add 150g of sweet potato or regular potato to your pre workout meal tomorrow and notice how your energy levels change during your session.
