Weight Gain Tips for Student-Athletes

“How can I/my kid gain weight? We have tried everything and can’t seem to get anywhere.” I get this question and concern daily from coaches and parents. Weight gain is really hard when athletes are young calorie-burning machines!

What guidebooks do you have to help with weight gain?

As always my objective is to provide people with simple and practical tips to achieve their goals!

“How to Gain Weight Tip List”

Test don’t guess! Start tracking what you’re eating to know how many calories you’re actually eating each day. Too often teen and college athletes are under-eating without knowing it. What is measured is well-managed. Download a free app to help with tracking calories, protein, fats, and carbs. You can’t gain weight if you’re not eating enough calories consistently to attain a calorie surplus. If you’re unwilling to track calories I recommend the plate method for weight gain. See our weight-gain performance plate here.

The mistake many make when trying to gain weight is not understanding fundamental portion sizes. Weight gain means half your plate comes from CHO and during weight loss, it would be 1/4 the plate (smaller portion = less kcal).

Too many teen athletes fail to consistently eat regular meals so this is a super easy place to start. (CLICK TO SEE THE FULL INSTAGRAM POST ON WEIGHT GAIN).

Eat breakfast consistently. Nutrients missed at breakfast are often not made up later in the day. Toast, eggs, and peanut butter paired with whole-fat chocolate milk are low-cost, high-calorie, and quality options. Try Greek yogurt parfaits with oats, nut butter, and fruit. Avocado egg toast is also super easy and high-calorie. For more ideas check out my Grab and Go Breakfast Ideas

Eat high-calorie snacks every two hours! Set alarms on phones or create email reminders to snack every few hours. (Weight gain requires eating in a calorie surplus so EAT UP!)

Pack high-calorie snacks. Peanut butter banana bagel sandwiches, trail mix, grab-n-go core power protein drinks, smoothies to store in a Yeti at school, peanut butter oat energy bites, mason jar protein oats

Planning ahead by meal prepping on the weekend

  • Grill up a dozen chicken breasts and steaks for the week to cut and portion out
  • Prepare PB energy bites
  • Hard-boiled eggs
  • Grab n Go Whole-fat chocolate milk
  • Oatmeal mason jars
  • Loaded baked potato + cheese + broccoli with butter
  • Greek yogurt parfaits (whole-fat dairy)
  • See my weight gain snacks here!

Special considerations for eating more:

  • Sample Weight gain breakdown
  • Double up on protein servings when dining out (double meat)
  • Add beef jerky, string cheese, nuts, seeds, nut butters, avocado, butter, olive oil, cheese, and whole-fat sour cream/Greek yogurt when you’re able for more calories!
  • Sometimes eating a lot of calories can be challenging especially around training. I recommend smoothies. You can consume half in the morning and half in the evening or afternoon as tolerated. Smoothies are a great liquid vehicle for calories! (oatmeal, peanut butter, whole-fat Greek yogurt, and whole-fat cow’s milk). See my Chunky Monkey Smoothie Recipe here
  • Recovery nutrition is key for muscle repair and growth. Prioritize a recovery snack or meal immediately post-training. Be sure to include both complex carbohydrates and protein.
  • Vary your protein throughout the day and be sure to power up with protein as part of your recovery snack to achieve a positive protein balance, promoting muscle growth and recovery. See my backpack portable options here!

“But Wendi, what about nutrient timing?” Great point, please see my 4-2-1 guidance here. Too much fat or too much solid food in the stomach around training can blunt performance.

I emphasize a food-first approach but supplements help supplement the gaps in our nutrition. Supplements like creatine, whey protein, vitamin D, and casein can be helpful for athletes’ muscle recovery, lean mass maintenance, and muscle gain when properly used. Should youth athletes use creatine? Find out what the research says in my blog.

Include a bedtime snack !! Research has effectively demonstrated that consuming casein protein (found in milk and
dairy products) prior to sleep can increase muscle
protein synthesis and facilitate better recovery.


How to simply start gaining weight:

  • Identify how much you’re eating. (track in an app or journal)
  • Add 300-500 kcal per day to your baseline intake. If you consume an added 500 kcal per day x 7 days a week you’re consuming 3,500 kcal equivilant to one pound.
  • Focus on doubing up on portions, adding in liquid kcal and staying consistent.
  • It won’t happen overnight. If you want to gain you’ve gotta eat!

Aim for consuming 4,000-6,000 kcal per day if you’re an HS athlete and likely 6,000 + kcal for collegiate athletes. For individual recommendations contact me and let’s create a custom fueling plan that supports weight gain goals.

I have worked with both HS and college athletes for > 5 years now. I spent time at the University of Florida as a sports nutrition intern in 2015 working with football, men’s and women’s track, swim, soccer, baseball, lacrosse, and tennis. I also worked as a performance nutrition assistant at the University of Wisconsin-Stout during my graduate studies. I educated football, gymnastics, hockey, soccer, men’s and women’s basketball, and baseball on proper fueling from 2014 to 2016. Both of these experiences were volunteer and I sought them out because I knew I wanted to help athletes as a future dietitian. These opportunities helped me understand what it takes to fuel an elite athlete with a small budget! Sleep for more gains..yes sleep impacts our ability to recover and synthesize muscle! Aim for 7-9 hours of sleep per night.

Many young athletes also skip breakfast and snacks so it’s more of a willingness than an ability problem with weight gain. If your young athlete won’t listen to you don’t worry you’re not alone! But they tend to listen to me, a former college athlete and total stranger :). I provide meal plans and performance nutrition guidance for picky eaters and those with food allergies/intolerances.
