Sports Nutrition in Daily Life

Your everyday choices impact your workouts and fitness goals! And…spoiler alert! Daily nutrition is usually enough to support most people’s fitness programs without additional nutrition. 

Here are components of energy and nutrients. Each of them is necessary for overall health and weight management and for supporting workouts. 

  • Energy (calories)
  • Protein
  • Carbohydrates
  • Fat
  • Vitamins
  • Essential minerals

All-Day Nutrition to Support Workouts

Here is an overview of calories and macronutrients (protein, carbohydrates, and fats) and their roles in supporting physical activity. 

Calories and Macronutrients

Enough energy and protein for workouts while managing weight 

Focus Area Function / Goal
Calories and Macronutrients Enough energy and protein for workouts while managing weight
Calories Enough energy within limits
Protein Muscle repair and recovery
Carbohydrates Quick and lasting energy supply
Healthy Fats Lasting energy, joint and cell recovery and repair

Plate Method for All-Day Nutrition to Support Workouts

The plate method is a flexible tool for portion control and balanced meals without hassle. 

Component Fraction of Plate / Frequency Nutrients / Roles
Vegetables ½ plate Vitamins, minerals, and fiber for stable energy and regularity
Lean Protein ¼ plate Muscle repair and maintenance; provides stable energy
Starch / Grains ¼ plate Primary energy and fuel; provides vitamins, minerals, and fiber
Healthy Fats Regularly include Joint health, cell repair, and lasting energy
Fruit Regularly include Antioxidants, vitamins, and quick energy
Reduced-fat Dairy Regularly include Bone health (calcium/Vitamin D) and protein

Maintaining Hydration All Day Supports Better Workouts

Water is the most critical nutrient all day and for workouts. Roles include:

  • Cooling through sweat
  • Maintain blood volume for nutrient and oxygen delivery (easier circulation)
  • Energy and concentration
  • Muscle and joint function

Mild dehydration (2% of body weight) can decrease performance and cognition. To stay hydrated, drink water or other low-calorie fluids throughout the day. 

Guidelines for within 2-3 hours before a workout are to drink 2-4 ml per lb body weight; that’s about 2-3 cups for a 200-lb person.

Fluid loss during exercise is about 0.3-2.4 L per hour, or about 1-10 cups per hour. That’s a big range! Needs are higher with more intense exercise, warmer weather, larger individuals, and people who naturally sweat more. 

Electrolytes are essential minerals that support normal cell function. Functions include:

  • Maintaining normal blood volume
  • Maintaining normal water balance
  • Allowing for normal muscle contraction/relaxation

These are four critical electrolytes and some food sources. 

Component Fraction of Plate / Frequency Nutrients / Roles
Vegetables ½ plate Vitamins, minerals, and fiber for stable energy and regularity
Lean Protein ¼ plate Muscle repair and maintenance; provides stable energy
Starch / Grains ¼ plate Primary energy and fuel; provides vitamins, minerals, and fiber
Healthy Fats Regularly include Joint health, cell repair, and lasting energy
Fruit Regularly include Antioxidants, vitamins, and quick energy
Reduced-fat Dairy Regularly include Bone health (calcium/Vitamin D) and protein

B Vitamins Are Essential for Energy Production

The “energy-producing” B vitamins support reactions in your body that produce energy from the food you eat. Some B vitamins act as “cofactors” to allow your body to break down food and generate energy. They support enzymes that allow metabolism to occur properly. 

B vitamins are in a variety of foods. 

  • Grains
  • Dairy
  • Eggs
  • Poultry and fish
  • Nuts and seeds
  • Beans and lentils
  • Fruit and vegetables

“Energy-producing V vitamins” include:

  • Vitamin B1 (thiamin)
  • Vitamin B2 (riboflavin)
  • Niacin (vitamin B3)
  • Pantothenic acid (vitamin B5)
  • Pyridoxine (vitamin B6)
  • Vitamin B12

Note that taking in higher amounts of B vitamins won’t produce more energy unless you are deficient in B vitamins. 

Checklist for All-Day Nutrition to Support Workouts

Using a simple checklist can help you check nutrition for supporting physical activity

Did I…

  • Use the plate method to put meals together?
  • Hydrate all day and before and after workouts? 
  • Eat a rainbow for antioxidants and nutrients?
  • Include reduced-fat dairy for bone support?

Pre-Workout Nutrition Is Individualized 

General guidelines for eating before a workout are to have a small meal 2-4 hours before your workout, or to have a small snack 30-60 minutes before. Eat according to your hunger and experience - what has worked for you in the past? 

Choose easily digestible foods that are low in fat, have low or moderate protein and are relatively low in fiber. Remember to hydrate!

Pre-Workout Nutrition

It’s an individual question! Consider…

  • Hunger
  • Blood sugar (if a consideration)
  • Time of day
  • Personal tolerance
  • Daily variation can affect pre-workout needs

Pre-workout fueling depends on individual factors and your needs. Choose simple foods that are easy to digest

Daily variation can affect pre-workout needs, e.g.,

  • Was the weather warm/cold?
  • Were you especially busy and unable to hydrate properly? 
  • Did you wake up late and skip a meal?

Pre-Workout Nutrition

Choose simple foods that are easy to digest

  • Oatmeal
  • Bananas
  • English muffin with jam
  • Brown rice cakes
  • Whole-grain bread
  • Pretzels
  • Nonfat yogurt
  • Applesauce

Limit foods that are tougher to digest. 

  • Fried foods
  • Fatty meats: hot dogs, sausage, bacon, salami
  • Full-fat cheese
  • Burgers, pizza
  • Spicy foods
  • Beans, lentils
  • Oversized portions

Take notes to see what works for you!

Post-Workout Nutrition 

Goals are to: 

  • Replenish glycogen (stored carbohydrate - fuel)
  • Provide muscles with protein for recovery
  • Restore lost fluids

Having a meal or snack with a ratio of 3:1 carbs:protein (3 grams of carbohydrates per 1 gram of protein) can support these goals. Aim for high-quality protein within 2 hours of finishing your workout. 

For example, you might have…

  • 45g carbohydrates and 15 grams of protein (240 calories)
  • 60g carbohydrates and 20 grams of protein (320 calories)

Remember to rehydrate!

Sample Post-Workout Snacks: If your next meal is not soon… 

  • Yogurt and fruit
  • Pretzels and low-fat cheese
  • Whole-grain English muffin and 1 tablespoon peanut butter
  • Whole-grain wrap with grilled chicken and vegetables
  • Apple or banana and 1-2 low-fat string cheese sticks
  • 1 hard-boiled egg and whole-grain crackers
  • ½ cup of beans and 1-2 ounces of low-fat cheese
  • ½ cup of low-fat cottage cheese and fresh fruit
  • ¾ cup of whole-grain cereal with ¾ cup skim milk
  • Snack mix with ½ oz nuts, grapes, whole-grain cereal

Sample post-workout meals: If your next meal is soon…

  • Turkey/black bean burger on whole-grain bun with low-fat cheese, baked zucchini “fries” or carrot sticks
  • Lentil or bean soup with vegetables, whole-grain roll or crackers
  • Salmon or tilapia bowl with vegetables and brown rice bowl
  • Green salad with cucumber and tomato, hard-boiled egg or tuna, low-fat cheese or beans, and vinaigrette dressing; piece of fruit
  • Egg and egg whites with spinach or other vegetables, diced sweet potato or white potato, and avocado
  • Whole-grain spaghetti with marinara sauce, shrimp or chicken, and a side salad

Calorie Calculation Example: Do you need extra calories after working out?

Energy Balance and Weight Loss
Daily Deficit (Calories In < Calories Out) Rate of Weight Loss
250 calories ½ lb per week
500 calories 1 lb per week
1000 calories 2 lb per week

Calories Burned

Activity Estimated Calories Burned per 30 Minutes
170 lb (77 kg) 200 lb (90 kg) 240 lb (110 kg)
Brisk walking (3.5 mph) 166 195 234
Jogging (5 mph) 308 363 436
Bicycling (12-14 mph) 308 363 436
Swimming laps (moderate) 270 317 381
Vigorous weight lifting 231 272 327
Yoga 116 136 163

During Workouts

Hydration: ½-1 cup water per 15-20 minutes

Factors Impacting Fluid Needs
More Fluid Needed Less Fluid Needed
Higher intensity exercise Lower intensity exercise
Warmer weather Cooler weather
Larger body mass Smaller body mass
Heavy sweating Lighter sweating

Fuel is not usually needed

Hydration and Fueling During Long, Intense Workouts

Examples of high-intensity activities

  • Running
  • Hard cycling
  • Lap swimming
  • Singles tennis
  • Basketball or soccer

Engaging in more than 60 minutes of high-intensity exercise at a time may lead to the need for additional attention. The general guideline is to take in 1.5-3 cups of fluids per hour, and electrolytes may be needed. 

Food and Nutrient Supplements

Category Potential Uses Concerns
Protein bars/shakes, energy gels/bars/shakes Convenience; can be easier on sensitive stomachs Cost
Gastrointestinal discomfort (e.g., bloating or gas)
Excess protein can strain kidneys
Megadoses (vitamins or minerals) N/A Potentially harmful if taken in excess without deficiency
BCAAs - Branched-Chain Amino Acids Aimed at reducing soreness; muscle "sparing" Often unnecessary if total protein intake is adequate
B vitamins, vitamin D, iron, omega-3 fats Prevent or address deficiencies Should be guided by blood work or professional advice

Most people can get enough protein, carbohydrates, and BCAAs from their regular food

Extra amounts don’t help if you’re already getting enough from your regular food

Popular Ergogenic Aids (Supplements)

Supplement Potential Uses Side Effects / Risks
Caffeine Reduce perceived effort; improve focus and endurance Jitters, increased heart rate, sleep disruption, GI distress
Creatine Increase power output and muscle mass in short, explosive bursts Water retention (initial weight gain), mild stomach cramping if under-hydrated
Sodium bicarbonate Buffers acid in muscles to delay fatigue during high-intensity (1–7 min) Significant gastrointestinal discomfort
Important Note: Dietary supplements are regulated differently than foods. Risks include:
  • Mislabeling of concentration (higher or lower amounts than stated)
  • Presence of toxins or other impurities

Good nutrition for weight lifting?

That’s a good question! 

Nutrition for weight lifting is similar to nutrition for other types of exercise. What you eat throughout the day matters most. In addition, getting some protein and carbohydrates within 2 hours of finishing a workout can improve muscle recovery and repair, and replenish glycogen (stored carbohydrate for fuel). 

Here are some tips.

  • For weight loss, it’s still important to have a calorie deficit. You won’t gain muscle as fast as if your goal is to gain weight, but it’s still possible to build muscle slowly with a calorie deficit. 
  • Protein recommendations for someone who is working out intensely and trying to build muscle are 0.7-1 gram of protein per pound of body weight per day. That translates to 140-200 grams of protein per day - spread throughout the day. High-quality protein sources include chicken, fish, shellfish, reduced-fat dairy products, tofu, and eggs. You can also get all essential amino acids from combining beans, whole grains, nuts and seeds, and vegetables. 
  • Carbohydrates and fat fuel workouts. High-fiber carbohydrates include whole grains, fruit, and starchy vegetables like sweet potatoes and peas. Healthy fat sources include avocados, olive oil, nuts, seeds, peanuts, canola oil, and fatty fish like salmon and tuna.
  • Non-starchy vegetables have important electrolytes, other minerals, and vitamins. 
  • Hydration is important, too!

Any tools for staying hydrated? How many ounces a water a day should you drink?

There are lots of tricks for staying hydrated! Here are a few ideas. 

  • Water is the best option. It’s calorie-free and healthy. Plain water, seltzer water, soda water, water with ice, water with slices of fruit, and water with herbs are great choices. 
  • Decaf black coffee and decaf unsweetened tea, herbal tea, and low-sodium broth are also options.
  • To remember to drink, try keeping a water bottle with you throughout the day. Setting a timer to remind you to drink can also help. 
  • Our Lark hydration worksheet can help you make your hydration plan!
  • Tracking your water consumption helps make sure you’re on track to hit your goals each day. Some people like water bottles with markings on the side to tell them how much more water they have to go for the day. 
  • The “adequate intake” for water is about 11 cups for women, and 15 cups for men per day. 
  • During a workout, the general guideline is to drink ½-1 cup of water per 15-20 minutes. After a workout, drink to replace the water you lost in sweat. 
  • A common way to estimate hydration is to look at the color of your urine. If you’re hydrated, it might look pale yellow. Dark brown can indicate dehydration. 

Be sure to ask your doctor if you have questions or concerns!

Is taking weight in the morning considered dry weight?

Yes. "Dry weight" or "true weight" is best measured first thing in the morning after using the bathroom and before eating or drinking anything. This minimizes fluctuations caused by food volume and hydration levels.

Do you get the same benefit from seltzer or sparkling water?

Good question! Yes, seltzer water and sparkling water are both as hydrating as water. Just remember that their bubbles (or carbonation) can cause bloating or gas for some people, and that can be quite uncomfortable during a workout. In addition, many brands of flavored sparkling water include artificial sweeteners, which can have negative effects according to some research. 

What are your thoughts on Gatorade? Is gatorade a good choice to drink after a workout to increase electrolytes? Or is it too much sugar?

Gatorade can be a powerful tool if you’re exercising intensely for over an hour, such as if you’re racing a marathon or half-marathon. It has fluid, electrolytes, and sugar for fuel. It can be used during and after workouts to maintain fluid and electrolyte balance and to replenish fluids and electrolytes. 

Sugar-free gatorade is also available if you want to avoid calories, though it has artificial sweeteners. 

For most people doing workouts of up to an hour, or workouts (such as brisk walkin) that are not considered high intensity, Gatorade and other electrolyte drinks are not typically necessary. Water is usually adequate for maintaining hydration status, and electrolytes consumed in daily life are typically enough. Consider asking your healthcare provider if you need electrolyte drinks or if you are having trouble getting through normal workouts.

Recommended protein bars?  barebells 20g protein bar is a preference

Barebells bars have 20 grams of protein and are low in sugar. They’re convenient, and lots of flavors are available. 

Some drawbacks may be that it contains artificial sweeteners (sucralose), as well as a sugar alcohol (maltitol) that can lead to diarrhea and gas in some people. In addition, like most protein bars and powders, they cost more per gram of protein than many high-protein, nutritious foods. 

What is the best way to combat night leg cramping after strenuous workouts?

Night cramps are common with mild dehydration and electrolyte imbalance, especially with low levels of magnesium or potassium. It’s important to hydrate properly and eat plenty of potassium and magnesium. Potassium sources include fruits, vegetables, whole grains, beans, fish, and yogurt. Magnesium sources include dark chocolate, seeds, some whole grains, and nuts. 

It’s important to talk to your healthcare provider about night leg cramps because they can have multiple causes. 

Are protein shakes good first thing in the morning for breakfast? This would take place of a meal.

Protein shakes can be very convenient and tasty, and they’re often fortified with vitamins and minerals. 

However, protein shakes can have a few potential drawbacks.

  • Liquid calories (like shakes) are less filing than solid calories, so you may feel hungry sooner than if you ate a meal with solid foods.
  • A protein shake may not be as balanced nutritionally as a meal with protein, healthy fats, and high-fiber carbohydrates. 
  • Having a shake instead of whole foods can leave you without certain nutrients in whole foods. For example, fruits and vegetables are sources of antioxidants and thousands of phytochemicals, or plant nutrients.

If you’re looking for a quick and portable meal, consider making breakfast the night before. A container of cottage cheese or yogurt with a pre-portioned amount of cereal in a little baggie, or overnight oats with some fruit and nuts, are examples of nutritious options that are ready to eat the next morning.

If I drink a lot of water during my workout am I immediately replenishing the water weight I lost during the workout?

You are likely replacing a good amount of the water you lost in your workout, but it depends on how much water you are losing during the workout. The body can only absorb about 16–32 ounces of fluid per hour. If you are sweating heavily, you may be losing fluid faster than your gut can absorb it. And, if you’re sweating heavily for a workout lasting 60-90 or more minutes, you may be unable to maintain your status.

One way to know is to weigh yourself before and after a workout. If your weight is the same, you’ve likely come close to replacing your water losses as they occurred during the workout. 

It's also important to note that if you are sweating heavily for a long time, such as more than 60-90 minutes, you may need electrolyte replacement as well to avoid a dangerous condition called hyponatremia.

What is 1 serving considered?

It depends on the food group, but general guidelines are:

  • Protein - 3 ounces
  • Grains - 1 ounce equivalent, or ½ cup cooked grains (brown rice, pasta, oatmeal), 1 slice of bread, 1 ounce of crackers or pretzels)
  • Starchy vegetables (like potatoes or sweet potatoes or corn) - ½ cup
  • Vegetables - 1 cup
  • Fruit - ½ cup
  • Cheese, nuts, peanuts - 1 ounce
  • Fats - 2 teaspoons of oil, or 2 tablespoons of salad dressing

Any particular brand of coconut water that is really coconut water?

Coconut water can be a source of potassium, which is an electrolyte. To see whether a brand is really coconut water, check the list of ingredients to see whether the first one listed is, “coconut water.” Many brands also have various types of added sugars, such as sugar or coconut sugar; to reduce sugar, choose a brand with no added sugars (you can check on the nutrition facts panel). Some brands also have added vitamins, such as vitamin C.

Coconut water has about 45 calories per 8-ounce cup, so it’s important to log or consider those calories when you’re thinking about your calorie consumption for the day.

What about diabetics?  As far as exercising for longer periods of time?

Individuals with diabetes need to be extremely careful when exercising. Please check with your healthcare provider! Exercise can lead to low blood sugar or high blood sugar, and effects can last during and for several hours after exercise. 

These are some questions to ask your provider.

  • Which activities are safe for me? 
  • Do I need to adjust any medications? 
  • When should I check my blood sugar before, during, and after workouts? What range should it be in when I start a workout, during my workout, and for hours afterwards? What should I do if it’s lower or higher than those ranges? 
  • When and what should I eat before, during, and after workouts? 
  • What if I exercise without having planned to do so?

Managing blood sugar and workouts with diabetes is a critical and individualized task - be sure to have a plan that you and your healthcare provider talk about!
