Is it good to eat candy while lifting? The truth about sugar and strength training

5 min read

While often viewed as a workout villain, strategically timed simple sugars can provide a quick energy boost. This raises the question: Is it good to eat candy while lifting? The answer is more nuanced than a simple yes or no, depending largely on your timing, intensity, and fitness goals.

Quick Summary

For weightlifters, candy provides rapid energy from simple carbohydrates, potentially beneficial post-workout for glycogen replenishment or pre-workout for long, high-intensity sessions. However, it lacks nutrients, can cause a sugar crash, and contributes to fat storage if not used immediately. Timing and moderation are crucial.

Key Points

  • Strategic Timing Is Key: Eating candy is only beneficial when timed correctly around intense workouts, not as a general snack.

  • Pre-Workout Boost (Rare): A small amount of low-fat candy can provide rapid energy right before a time-crunched, high-intensity session.

  • Post-Workout Recovery (Highly Effective): Combining simple carbs from candy with protein immediately after a workout maximizes glycogen replenishment and muscle repair.

  • Avoid the Sugar Crash: Excessive candy can cause a blood sugar spike and crash, leading to fatigue and poor performance mid-workout.

  • Focus on Whole Foods: Candy provides empty calories; prioritize nutrient-dense complex carbs like oats and sweet potatoes for sustained energy throughout the day.

  • Choose Low-Fat Options: Opt for low-fat, simple sugar candies (like gummies) over high-fat chocolate to avoid slowing digestion and causing GI issues.

Simple vs. Complex Carbs: What’s the Difference?

To understand the role of candy in a weightlifter's diet, it’s essential to distinguish between simple and complex carbohydrates. Your body breaks down all carbs into glucose, which fuels your cells. The key difference lies in the speed of this process and the additional nutritional value provided.

  • Simple Carbohydrates: These are single or double sugar molecules found in foods like candy, table sugar, and fruit. They are broken down and absorbed quickly, causing a rapid spike in blood sugar and a fast energy release. This provides immediate fuel but can be followed by a 'sugar crash' as blood sugar levels fall. Candies typically fall into this category but lack the vitamins, minerals, and fiber of healthier simple carbs like fruit.
  • Complex Carbohydrates: These consist of longer chains of sugar molecules found in whole grains, oats, legumes, and starchy vegetables. They take longer to digest, providing a slower, more sustained release of energy. Complex carbs are typically richer in fiber and essential micronutrients, making them a more nutritious option for consistent energy throughout the day.

The Strategic Timing of Simple Sugars

When considering whether to eat candy while lifting, timing is everything. The benefits of simple carbs are highly dependent on when you consume them relative to your workout.

Pre-Workout Fueling

For most standard weightlifting sessions under 60 minutes, a balanced pre-workout meal with complex carbohydrates eaten 2-3 hours beforehand is sufficient. Your muscle glycogen stores should provide the necessary energy. However, there are scenarios where a small amount of simple carbs could be useful:

  • Right Before a Workout: If you have less than 30-60 minutes before a high-intensity session and haven't had a proper meal, a small handful of gummy bears or a dextrose-based chew can provide a rapid, easily digestible energy source. This is not necessary for low-intensity sessions, where your body primarily burns fat.

During Long and Intense Sessions

For extended, high-volume, or multiple-session workouts, simple carbs can help maintain energy levels and delay fatigue.

  • Maintaining Performance: During grueling training sessions that last over 90 minutes, such as a long-distance run or a high-volume bodybuilding workout, consuming 30-60 grams of simple carbs per hour can help keep your blood sugar levels stable.

Post-Workout Recovery

This is arguably the most beneficial time for a weightlifter to consume simple sugars. After a strenuous workout, your muscle glycogen stores are depleted, and your muscles are highly sensitive to nutrient uptake.

  • Accelerated Glycogen Replenishment: Consuming simple carbs immediately after a workout, especially in combination with protein, triggers an insulin spike. Insulin helps shuttle glucose and amino acids into your muscle cells, rapidly replenishing glycogen stores and initiating the repair and growth process.

The Downsides of Relying on Candy

While strategic use of simple sugars has its place, relying on candy for workout fuel comes with significant drawbacks that can hinder progress and overall health.

Nutrient Deficiency

Unlike natural sources of simple sugars (e.g., fruit), candy provides empty calories. It offers none of the vitamins, minerals, antioxidants, or fiber essential for optimal bodily function and recovery. Displacing nutrient-dense foods with candy can lead to deficiencies that undermine your fitness goals and general health.

Risk of Unwanted Fat Gain

Excessive sugar intake, especially outside the strategic pre/intra/post-workout window, can lead to increased fat storage. When your body has more glucose than it needs for immediate energy or glycogen replenishment, it converts the excess into fat. This is particularly problematic during a cutting phase.

Energy Spikes and Crashes

The rapid rise and fall of blood sugar caused by high-sugar candy can lead to a dreaded mid-workout crash. This can result in fatigue, reduced motivation, and poor performance, completely negating the initial energy boost and potentially leaving you feeling worse than when you started.

Gastrointestinal (GI) Distress

Many candies contain fat, food dyes, and other processed ingredients that can cause GI upset when consumed during or immediately before exercise. Bloating, gas, and cramps can ruin a workout and are a common side effect of poorly chosen workout fuel.

Comparison: Candy vs. Optimal Carb Sources

Feature Candy (Simple Carbs) Optimal Carb Sources (Simple & Complex)
Energy Source Rapid, short-lived burst Sustained, long-lasting energy
Optimal Timing Right before (short notice) or immediately after intense sessions 2-3 hours before (complex), right before (simple), and immediately after workout
Glycogen Replenishment High-speed, most efficient when post-workout with protein Gradual (complex) throughout the day, rapid (simple) post-workout
Nutritional Value Empty calories, lacks vitamins and minerals Nutrient-dense, rich in vitamins, minerals, and fiber
Potential Downsides Sugar crash, fat gain, inflammation, GI distress None when chosen wisely and portioned correctly
Best For Strategic, timed use around specific, intense training Consistent, optimal fueling for performance and health

How to Use Candy Strategically (and Wisely)

If you choose to use candy as a strategic workout tool, remember these rules:

  1. Timing is Key: Reserve the use of simple sugars for either immediately before a time-crunched, high-intensity session or immediately post-workout with your protein shake for recovery.
  2. Stick to Low-Fat Options: Avoid chocolate and high-fat candies that can slow digestion and cause stomach upset. Opt for simple sugar options like gummy bears or dextrose chews.
  3. Use in Moderation: A small handful is all that is typically needed. For example, 15-20g of simple sugar pre-workout is often plenty.
  4. Listen to Your Body: What works for one person may cause GI issues for another. Experiment with different options during low-stakes workouts to find what your stomach tolerates.

Conclusion

So, is it good to eat candy while lifting? The answer is a qualified yes, but only when timed and consumed strategically. Relying on candy as a primary fuel source is detrimental due to its lack of nutrients and the risk of energy crashes and fat gain. For most weightlifters, the foundation of a solid diet should be nutrient-dense whole foods rich in complex carbohydrates, lean proteins, and healthy fats. However, a small, low-fat candy can be a highly effective, fast-acting tool for jumpstarting glycogen replenishment after an intense workout or providing a quick boost before a particularly strenuous training session. The key is to see candy not as a daily dietary staple, but as a specialized tool for specific performance and recovery needs.

Healthy Alternatives to Candy

If you want the benefits of fast-acting carbs without the downsides of candy, consider these healthier alternatives:

  • Dates or Raisins: Provides natural sugars with some fiber and electrolytes.
  • Rice Cakes with Honey: A quickly digestible combo of simple and complex carbs.
  • A Banana: Packed with simple sugars and potassium to help with electrolyte balance.
  • Sports Drinks: Many sports drinks are essentially simple sugars and electrolytes, providing a convenient way to fuel during long workouts.

Pre-Workout Strategies for Stable Energy

  • 2-3 Hours Before: A balanced meal with complex carbs (oatmeal, sweet potatoes) and protein.
  • 30-60 Minutes Before: A small snack of easily digestible carbs like a banana or rice cakes.

Post-Workout Recovery Protocol

  • Within 30 Minutes: A scoop of protein powder mixed with a simple carb source, like a handful of gummy bears or a sports drink, to spike insulin and replenish glycogen.
  • Within 1-2 Hours: A complete meal with complex carbs, protein, and healthy fats (e.g., chicken, brown rice, and vegetables) to sustain recovery.

Frequently Asked Questions

Bodybuilders sometimes eat candy strategically to provide a fast source of energy for an intense workout or to rapidly replenish glycogen stores after training, especially when combined with protein.

Low-fat, simple sugar candies like gummy bears or dextrose-based chews are preferred. High-fat options like chocolate should be avoided during or immediately before exercise as they can cause GI distress.

Excessive sugar intake, especially when not used for energy or recovery, can be stored as fat. The risk is high if you eat candy outside the strategic workout window or in large quantities.

For a quick energy boost, a small amount of low-fat candy can work similarly to some pre-workout supplements. However, supplements often contain additional ingredients like caffeine and electrolytes that candy lacks.

Only for very long, intense sessions (over 90 minutes) is eating simple carbs during the workout beneficial for maintaining energy. For most standard weightlifting, it is unnecessary and risks a sugar crash.

The rapid insulin spike from simple sugars helps transport amino acids (from the protein) and glucose into muscle cells more efficiently, accelerating muscle repair and glycogen replenishment.

Healthier alternatives include fruit (like bananas or raisins), rice cakes with a small amount of honey, or a sports drink during long sessions. These can provide simple carbs with fewer added ingredients and potential GI issues.
