What are Carbohydrates & Why You Need Them

Carbohydrates are the body's primary and most efficient source of fuel. When digested, they break down into glucose, which is either used immediately for energy or stored in your muscles and liver as glycogen. For anyone engaged in weight training, physical sports, or high-intensity activity, keeping glycogen stores full is critical to maintaining peak training performance.

Cutting carbs drastically can lead to muscle fatigue, poor focus, and a drop in workout intensity. Rather than treating carbohydrates as an enemy, you should calculate your exact carbohydrate needs and align them with your physical activity. Pairing your daily nutrition with high-quality protein, such as SUPPS protein, ensures you support muscle protein synthesis alongside energy replenishment.

How Carbohydrate Targets Are Calculated

To find out how many grams of carbohydrates you should eat daily, we first establish your baseline energy levels. This is a multi-step process utilizing standard metabolic equations:

Step 1: Calculate your Basal Metabolic Rate (BMR)

BMR represents the number of calories your body burns at rest just to keep you alive. Our calculator uses the highly accurate metabolic formula:

For Men:

BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) + 5

For Women:

BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) - 161

Since BMR is only the baseline at rest, you can determine your complete baseline metrics utilizing our BMR Calculator directly.

Step 2: Apply the Activity Multiplier

To find your Total Daily Energy Expenditure (TDEE), your BMR is scaled depending on how active you are throughout the week:

  • Sedentary×1.2
  • Lightly Active×1.375
  • Moderately Active×1.55
  • Very Active×1.725
  • Extra Active×1.9

This activity scale allows us to determine active calories. To learn more about calculating complete baseline expenditures, you can access our full TDEE Calculator.

Macronutrient Split Ratios by Fitness Goal

Once your target daily calories are adjusted based on your goals, they are split into specific macronutrient percentages. We use precise ratios recommended by nutrition experts to support muscle mass, body composition, and training capacity:

Weight Loss

Reduce calories by 10%, 15%, or 20% depending on deficit preferences.

40% Carbs / 40% Pro / 20% Fat

Maintenance

Calories remain unchanged to sustain weight levels and optimize performance.

40% Carbs / 30% Pro / 30% Fat

Weight Gain

Add a clean 500-calorie surplus to support skeletal muscle hypertrophy.

40% Carbs / 30% Pro / 30% Fat

When losing weight, tracking your body composition ratios ensures you are losing fat rather than lean muscle tissue. You can check your ratios using our Body Fat Calculator alongside these targets.

Carbohydrates and Athletic Performance Synergy

Carbohydrates do not work in isolation; their physiological effects are highly synergistic with key sports supplements:

1. Shuttle Creatine into Muscle Cells

Eating high-glycemic carbohydrates creates an insulin spike. Insulin activates sodium-potassium pumps in muscle cell membranes, which drastically increases the uptake of creatine. By consuming your carbohydrate meals with SUPPS Creatine monohydrate, you can improve creatine loading efficiency by up to 60%.

2. Accelerate Recovery & Prevent Muscle Breakdown

Post-workout carbohydrate consumption restores depleted muscle glycogen. When paired with a fast-absorbing whey like SUPPS isolate, the insulin response works together with amino acids to block cortisol (which breaks down muscle) and kickstart protein synthesis.

Best Carbohydrate Sources

Focus on consuming high-quality, nutrient-dense carbohydrates that provide stable energy. Here is a table comparing popular carb sources based on their carb content per 100 grams:

SourceCarbs / 100gType
Oats (raw)66gComplex Carb
Whole Wheat Roti45gComplex Carb
White Rice (cooked)28gSimple/Refined Carb
Brown Rice (cooked)23gComplex Carb
Banana23gSimple Carb
Quinoa (cooked)21gComplex Carb
Sweet Potato (boiled)20gComplex Carb
Potato (baked)17gComplex/Simple Carb

Values are approximations. Raw metrics will vary depending on cooking methods and hydration of grains.

Frequently Asked Questions

Will carbs make me fat?

No. Weight gain is caused by a calorie surplus, not carbohydrates. If you consume carbs within your daily calorie target, you will not gain body fat. Carbs are essential to fuel your training sessions.

What is the difference between simple and complex carbs?

Complex carbs (oats, brown rice, potatoes) contain fiber and digest slowly, providing stable energy. Simple carbs (fruit, white rice) digest quickly and are ideal pre or post-workout to quickly replenish glycogen.

How many carbs do I need for fat loss?

During a fat loss phase, we recommend maintaining carbohydrates at 40% of your reduced calories. This keeps training intensity high, helping you preserve muscle while burning fat.

Should I eat carbs before sleep?

Yes, eating carbs at night is fine. It can support recovery and even help with sleep quality by assisting in serotonin production. Focus on your total daily carbohydrate intake rather than strict timing.
