How to Set Your Calorie, Protein, and Fiber Targets

Step-by-step guide to calculating your daily calorie, protein, and fiber targets for weight loss, plus how to break them into meal-level goals.

This guide walks you through setting your daily targets for weight loss and breaking them into practical meal-level goals.

TargetWomenMen
Calories (for ~1 lb/week loss)1,400–1,700/day1,700–2,100/day
Protein120–160g/day150–200g/day
Fiber25–30g/day30–38g/day

Step 1: Calculate Your Calorie Target

Option A: Use the Reference Table

Find your approximate calorie target based on age, sex, and current weight:

Women:

Age / Weight120 lbs140 lbs160 lbs180 lbs200 lbs220 lbs
25–351,3001,4001,5001,6001,7001,750
35–501,2501,3501,4501,5501,6501,700
50+1,2001,3001,4001,5001,6001,650

Men:

Age / Weight140 lbs160 lbs180 lbs200 lbs220 lbs240 lbs
25–351,7001,8502,0002,1002,2002,300
35–501,6501,8001,9502,0502,1502,250
50+1,6001,7501,9002,0002,1002,200
  • If you’re very active (exercise 5+ days/week) → add 100-200 calories
  • If you’re sedentary (desk job, minimal exercise) → subtract 100-200 calories
  • If between weights → round to the nearest column

Step 2: Calculate Your Protein Target

The Formula

0.8–1 gram of protein per pound of body weight

Your WeightProtein Target Range
120 lbs96–120g/day
140 lbs112–140g/day
160 lbs128–160g/day
180 lbs144–180g/day
200 lbs160–200g/day
220 lbs176–220g/day

Which End of the Range?

  • If less active or finding protein targets difficult → use lower end (0.8g/lb)
  • If doing resistance training → use higher end (1g/lb)
  • If on GLP-1 medication → use higher end (muscle preservation is critical)
  • If over 50 → use higher end (muscle loss accelerates with age)

Step 3: Calculate Your Fiber Target

Daily Fiber Target
Women25–30 grams
Men30–38 grams
  • If currently eating less than 15g fiber/day → increase gradually over 2-3 weeks to avoid digestive discomfort
  • If experiencing bloating when adding fiber → slow down the increase
  • If constipated → fiber + water intake both need attention

Step 4: Break Daily Targets into Meals

Meal% of DailyExample (1,600 cal / 140g protein / 30g fiber)
Breakfast20%320 cal / 28g protein / 6g fiber
Lunch35%560 cal / 49g protein / 10g fiber
Dinner35%560 cal / 49g protein / 10g fiber
Snacks10%160 cal / 14g protein / 4g fiber

Example Meals That Hit These Targets

Breakfast (320 cal / 28g protein / 6g fiber)

  • 3 scrambled eggs (210 cal, 18g protein)
  • 1 cup berries (60 cal, 4g fiber)
  • ½ cup Greek yogurt (50 cal, 10g protein, 2g fiber)

Lunch (560 cal / 49g protein / 10g fiber)

  • 6 oz grilled chicken breast (280 cal, 52g protein)
  • 2 cups mixed salad greens (20 cal, 2g fiber)
  • ½ cup black beans (115 cal, 8g protein, 7g fiber)
  • 1 tbsp olive oil + vinegar dressing (120 cal)
  • Cherry tomatoes, cucumber (25 cal, 1g fiber)

Dinner (560 cal / 49g protein / 10g fiber)

  • 6 oz salmon (350 cal, 40g protein)
  • 1.5 cups roasted broccoli (65 cal, 6g fiber)
  • 150g sweet potato (130 cal, 4g protein, 4g fiber)
  • Herbs and lemon (15 cal)

Snack (160 cal / 14g protein / 4g fiber)

  • Protein shake (120 cal, 24g protein)
  • 1 small apple (40 cal, 4g fiber)

Use Targets as a Compass, Not a Calculator

Track at the Start, Then Ease Off

  • Weeks 1-4: Log meals to build portion awareness
  • Weeks 5+: Rely on established patterns; log only when troubleshooting

Focus on Protein First

Of the three targets, protein has the biggest impact on satiety. If you can only focus on one number, make it protein.
