How to Manage Diets as a Couple

Once you decide to eat healthy together, a proper diet as a couple falls into place, right? Wrong. Outside of the confusion that surrounds diets and healthy eating for one person, the difficulty multiplies when meal planning for two.

We’ve compiled the common complaints we hear from couples, like “He eats a ton of food and never gains an ounce” to “She’s on a diet so now I’m always starving!” Read on for our guide on how to manage your diets as a couple.

Diet Challenges Couples Face

For us, it took years to master our nutrition individually, and then as a couple. There were a lot of details to work through. How do we eat together when Alex is vegetarian, and I eat a meaty bodybuilder’s diet? How do we manage portion sizes when I weigh 70% more than Alex and burn 3X the calories during the same workout? How to we bring only high quality foods into our household?

This article breaks down how to overcome these challenges so that you and your partner can reach your goals and feel healthy.

A Guide to Managing Your Diet as a Couple

Managing nutrition is a challenge for all couples. We hear comments like this frequently from Duo Life couples.

  • “He eats tons of food and never gains an ounce.”
  • “He starts working out, cuts out junk food, and within a week he’s lost 10 pounds.”
  • “She is on a diet now, so I am always starving.”
  • “Whenever we work out together, she gets discouraged because she doesn’t see the results I do.”
  • “He is starving all the time, and his hanger interrupts our day.”

If any of the above sound familiar, the steps in our guide will clarify how to manage your nutrition as a couple properly.

Step #1: If you’re not the same gender, weight, and body composition, you shouldn’t eat the same amount of food.

It’s unlikely that you and your partner require the same portions, as it all comes down to age, weight, body composition, gender, and weight goals.

Therefore, every few years, it’s a good idea to calculate precisely how many calories you and your partner should be eating. This calculator from the Mayo Clinic will provide you both with a baseline. Also, it never hurts to double-check your work. Here’s another calculator we like.

If you share meals, knowing your differences in calorie baselines are essential to managing your diet as a couple.

  • For Ryan: Caloric baseline is 2700 calories per day
  • For Alex: Caloric baseline is 1700 calories per day

Note: Adult women, no matter their weight, should never consume less than 1200 calories per day. Adult men should never consume less than 1600 calories per day. These values are the minimum amount of calories that your body needs to function. If you are heavier or want to gain weight, daily caloric intake should be significantly higher. Alex, for example, is incredibly petite at just over 100 pounds, yet we regularly talk to heavier clients who try to eat less than her! 

If your interested in learning how to understand your calories for sustainable weight loss and weight management, this 30-day weight loss challenge is perfect for you.

Step #2: Make a portion ratio to remember.

Now that you have your caloric baselines, it’s time to factor in your health goals. Then, calculate a portion ratio to manage your diet as a couple.

In generic terms, you add calories to your caloric baseline based on your health goals. The more active you are, the more calories you require. Here’s a rule-of-thumb guide on how to determine the calories you need on top of your baseline.

  • For those who want to gain mass and get bulky, add 800-1000 calories to your caloric baseline
  • If your goal is to get ripped and gain muscle, add 400-600 calories to your caloric baseline
  • To maintain, don’t add any calories on to your caloric baseline
  • For those who want to get lean and lose body fat, take your weight in pounds and multiply it by 10 to get your target calories in a day. Make sure you don’t go below the minimum requirements for your gender

Of course, all of these target calorie calculations should be paired with an optimized weightlifting, cardio, or HIIT workout.

It’s highly beneficial to use calorie data from a heart rate monitoring device (our favorites the Polar H7 Chest Strap and the Apple Watch) to compare how many calories your bodies burn, individually. Make sure you’re following the same workouts for this comparison. For us, it’s not uncommon for me to burn 3X the calories that Alex would.

You can see our exact calorie burn measurements during our cardio experiment aimed at finding the best cardio workout. With this knowledge, here are our daily calorie targets:

  • For Ryan, who wants to gain muscle, his goal is 3300 calories per day. 
  • For Alex, maintaining weight means her calorie goal is 1700 calories per day.

Therefore, I am supposed to eat 2X as much as Alex. That’s a significantly different portion ratio. 

So, when we’re at a restaurant and order the same dish, we don’t both join the clean plate club. Or when at home, instead of dishing up our egg scramble 50/50, we apply our portion ratio. Since I eat 2X the calories Alex does, I would take two-thirds of the dish while Alex gets the remaining one-third.

Splitting our meals this way gets tough when serving up slices of pie or those prized avocados, but following this simple portion ratio helps us reach our goals and feel healthy. 

Step #3: Deal with varying food preferences.

Whether there are allergies, preferences, or other dietary restrictions, this complicates managing your diet as a couple. 

We all want to sit together at the table. That is until you remember your partner is vegetarian, dairy-intolerant, gluten-free, soy-free, and allergic to nuts. The food eaten and cooked within the house needs to be a compromise.

For us, when I was eating a meat-filled, bodybuilder’s diet and Alex ate a vegetarian diet, we cooked separately. We would be in the kitchen at the same time so that we could still eat together, but everything else was very separate except for the veggie side dishes. 

Over time, my diet increasingly became more vegetarian. Meat started to make me feel unhealthy and sometimes light-headed. So, I transitioned and learned how to eat more vegetables.

With that, it worked best for us to eat only vegetarian at home to share meals (again, always using our ratio of thirds). The compromise was that I would eat meat only at restaurants.

Over time, our diets meshed together, and we eat all of the same meals. Of course, this isn’t always possible, depending on dietary needs. With that, it takes more responsibility knowing how your meal fits into your general calorie plan.

If you need help visualizing your calorie plan in food form, these portion-control containers helped us significantly when we began managing our nutrition as a couple. Of course, it’s not sustainable to measure all your meals with containers forever. But, you won’t need to because you quickly learn to visualize your portions better. If you’re the type that follows a structured plan and recipes well, the Ultimate Portion Fix is worth your investment.

Rule #4: What to do if one partner isn’t on board with the couple’s diet?

Whether one person is obsessed with their fad diet (hint: we don’t support fad diets), or can’t give up their nightly ice cream and beer, it can derail the other. This also breeds resentment and judgment, which never support a healthy relationship.

In this case, stay committed to your health journey and lead by example. Ask your partner to keep their junk food in a separate room or the freezer. Out of sight, out of mind. If you find this food too tempting, log what you eat in a journal to stay accountable to yourself.

It is hard to reach your overall health goals when you’re not in alignment. We recommend you start by working out as a couple. The benefits of exercising together will fuel motivation to eat healthier together. 

Rule #5: Track unexpected perks.

Managing our diets has allowed me to control my hanger better. In Alex’s words, “Before, seemingly out of nowhere, Ryan would get hangry and completely ravenous — sometimes so much so that it would derail our plans (and diet) while we stopped what we were doing to find him a snack.”

Now that we eat proportionally the same amount of food, our stomachs start to rumble around the same time. We’re either both full or both still hungry, so at least we’re now on the same page and can plan our diet better as a couple.

Other unexpected perks include a similar rate of weight loss and feelings of satisfaction after meals. As you’re actively managing your nutrition as a couple, track the perks and stay on track.

30-Day Weight Loss Challenge

As engineers with ten years of health coaching experience, we needed to create a data-driven way for our clients to sustain weight loss. The number on the scale matters for weight loss, but other numbers are significantly more important. 

Too many weight loss challenges involve a long list of what you can, cannot, and need to do every day. We’ve reduced the overwhelm and only require you to track five numbers a day — calories, steps, fiber, sleep, waistline. In this 30-day weight loss challenge, you'll track five numbers daily to give you the highest return for sustainable weight loss.
