How to Determine Your Macro Breakdown

How to Determine Your Macro Breakdown

by | May 9, 2019 | All, Ask Our Dietitian, Home, Nutrition

Question:

I would like to know how I determine what my macro breakdown should be? How do I know how to calculate my split as far as protein/fats/carbs based on my weight & height? And what carbs are good for me? Female, Weight 170 lbs., Height 5’2’, Weightlift 5 days per week Cardio 3-5 times per week. I need help (guidance) with the nutrition part of my weight loss journey.

– Yolanda G.

Answer:

Given your current exercise regimen, your estimated daily energy needs for weight loss are about 2,000 calories if 20-30 years old (subtract 75 calories per decade older). Not knowing anything about your present intake, I’d recommend a rough caloric distribution of 30% fat, 20% protein, and 50% carbohydrates. Breaking down the 2,000 calories would give us 67 gm fat, 100 gm protein and 250 gm carbohydrate per day.

I’m so glad you asked about which carbohydrates are good! That indicates you’re aware that quality matters as much as quantity – for all three macronutrients. Complex carbohydrates that are more wholesome (less refined) are preferred over processed sources. Think of oats, quinoa, corn, potatoes, and vegetables complimented by simple carbohydrates from fresh fruit and milk products.

Here’s a one-day sample 2,000 calorie menu providing 27% fat, 22% protein, and 51% carbs*:

  • Breakfast – 1 Cup bran cereal, 1 Cup 1% milk, 1/2 grapefruit, and 1 large egg
  • Lunch – 3 oz. tuna, 1 Tbsp. mayonnaise, 4 rye crisp crackers, large dark green salad, ½ C. chickpeas, 2 Tbsp. of oil-based or ‘green goddess’ dressing
  • Dinner – 4 oz. skinless chicken breast, 1 Cup of broccoli, ½ Cup of corn

3 Snacks –

  • 1 large apple with 2 Tbsp. of peanut butter
  • 1 carrot + 1 celery with ¼ Cup of hummus
  • 6 oz Greek-style plain yogurt with 1 Cup berries

What Are Macronutrients? | Q+A

What Are Macronutrients? | Q+A

by | Apr 18, 2017 | All, Ask Our Dietitian, Home, Nutrition

Question:

I am confused about macro nutrients.  Can you clarify what this means and how I can use this to help lean out? Please help me understand what macro nutrients are and how it can help me lean down.

– Marlyn L.

Answer:

Macronutrients are simply the classes of nutrients needed in large amounts, which includes carbohydrate, fat and protein. These provide energy in the form of calories (carb and protein 4 cals/gm, fat 9 cals/gm). Alcohol – not a nutrient – is the other food molecule that has calories (7 cals/gm). While the remaining 3 essential nutrients – water, vitamins and minerals – have zero calories.

Your current diet includes all 3 macronutrients. To say “use macronutrients” to help you lean out, seems to imply a structured ratio of the three. I will speak to this below, but first let me say that the overwhelming body of evidence regarding weight loss diets show that it’s a moderate restriction of calories, regardless of method, that achieves long-term weight loss.

What should your MACRONUTRIENTS intake be?

Each person’s effective macronutrient distribution for leaning out may be different. Are the changes required to meet a desired ratio sustainable for your lifestyle? How different is the proportion of macronutrients from what you’re currently eating? The US Dietary Guidelines recommend 10-30% calories from protein, 25-35% calories from fat and 45-65% calories from carbohydrate for healthy adults. You could reach your goals with 10% protein, 35% fat and 55% carbohydrate as easily as you might with 30% protein, 25% fat and 45% carbohydrate, assuming your activity level and energy intake are appropriate.

If you do decide to adhere to set percentages from each macronutrient, the act of tracking and analyzing your intake to determine your balance may be a major promotor of dietary change, thus caloric intake and weight loss. See our previous article: Keep a Food Diary, Log or Journal and Lose Weight Faster.
