How Many Calories to Eat to Lose 2 Lbs/Week

Losing 2 pounds per week is the upper limit of what most health professionals consider safe and sustainable. It’s aggressive — no sugarcoating that. But it’s doable if you set up your calorie deficit the right way and dodge the common mistakes that lead to muscle loss, metabolic slowdown, and binge-restrict cycles.

Here’s the math, the strategy, and the reality check.

The Simple Math (With a Few Caveats)

One pound of body fat contains roughly 3,500 calories. To lose 2 pounds per week, you need a weekly deficit of 7,000 calories — which shakes out to a daily deficit of 1,000 calories.

That deficit comes from your Total Daily Energy Expenditure (TDEE) — the total number of calories your body burns in a day, exercise included. So if your TDEE is 2,400 calories, you’d eat 1,400 calories per day to hit a 1,000-calorie deficit.

Sounds simple enough. But there are some important caveats.

Why the 3,500-Calorie Rule Isn’t Perfect

The 3,500-calorie rule assumes you’re losing pure fat. In reality, weight loss is a mix of fat, water, and some lean tissue. Early weight loss includes a lot of water loss (especially if you cut carbs), which means the first two weeks may show faster results than expected. As you get leaner, fat loss slows and the same deficit produces smaller changes on the scale.

This is normal. It doesn’t mean the deficit stopped working.

Finding Your Personal Calorie Target

You need two numbers: your Basal Metabolic Rate (BMR) and your TDEE.

Step 1: Figure Out Your BMR

Your BMR is the number of calories your body burns at complete rest — just keeping you alive. It accounts for about 60 to 70 percent of your daily calorie burn. The main factors: age, sex, height, and weight.

Use our BMR calculator to get an accurate estimate based on the Mifflin-St Jeor equation, which research shows is the most accurate formula for most adults.

Step 2: Calculate Your TDEE

Multiply your BMR by an activity factor:

• Sedentary (desk job, no exercise): BMR x 1.2
• Lightly active (exercise 1-3 days/week): BMR x 1.375
• Moderately active (exercise 3-5 days/week): BMR x 1.55
• Very active (exercise 6-7 days/week): BMR x 1.725

Our daily calorie calculator handles this math and factors in your weight loss goal.

Step 3: Subtract 1,000

Your daily calorie target for 2 pounds per week of loss = TDEE minus 1,000. But there’s an absolute floor: women shouldn’t go below 1,200 calories and men shouldn’t go below 1,500 calories per day without medical supervision.

If subtracting 1,000 from your TDEE drops you below those floors, a 2-pound-per-week goal is too aggressive for you right now. A 1 to 1.5 pound per week target would be safer and more sustainable.

What You Eat Matters Almost as Much as How Much

Eating 1,400 calories of candy would create the same deficit as 1,400 calories of balanced meals. But the results? Drastically different. Here’s how to split your macros for fat loss — not muscle loss.

Protein: This Is Non-Negotiable

During a calorie deficit, protein is your best friend. It preserves lean muscle mass, keeps you fuller longer, and has the highest thermic effect (your body burns 20 to 30 percent of protein calories just digesting it).

Aim for 0.8 to 1.0 grams of protein per pound of body weight. For a 180-pound person, that’s 144 to 180 grams of protein per day. If you want to lose fat instead of muscle, don’t skimp here.

Fat: Essential but Calorie-Dense

Keep fat at 25 to 30 percent of total calories. Fat is essential for hormone production, vitamin absorption, and brain function. Going below 20 percent can disrupt hormones — especially in women.

Carbs: Whatever’s Left

After protein and fat are set, remaining calories come from carbohydrates. Prioritize complex carbs (vegetables, whole grains, legumes) over simple ones. The fiber from these sources supports digestion and keeps you feeling satisfied.

Does Meal Timing Matter?

There’s no magic meal timing that accelerates fat loss. What matters is finding an eating pattern you can actually stick with.

That said, spreading protein evenly across meals (30 to 40 grams per meal if you’re eating three times a day) maximizes muscle protein synthesis compared to cramming most of your protein into dinner. This becomes especially important during a deficit, when your body is more inclined to break down muscle for energy.

What a Day at 1,600 Calories Might Look Like

• Breakfast (400 cal): 3 scrambled eggs, 1 slice whole grain toast, 1/2 avocado
• Lunch (450 cal): Grilled chicken salad with mixed greens, chickpeas, olive oil dressing
• Dinner (500 cal): Baked salmon, roasted broccoli, 1/2 cup brown rice
• Snack (250 cal): Greek yogurt with berries and a handful of almonds

Stuck at a Plateau? Here’s How to Break Through

After 4 to 6 weeks of consistent deficit, weight loss often stalls. This is metabolic adaptation — not failure. Your body has adjusted to the lower calorie intake by dialing down non-exercise activity and tweaking your hormonal metabolic rate.

Here’s what actually helps:

1. Take a diet break. Eat at maintenance calories (your current TDEE) for one to two weeks, then get back to the deficit. This helps reset hunger hormones.
2. Recalculate your TDEE. A 20-pound lighter person burns fewer calories. Update your numbers.
3. Walk more. Aim for 8,000 to 10,000 steps daily. This can add 200 to 400 calories of daily burn without feeling like “exercise.”
4. Add resistance training. Building or preserving muscle keeps your metabolic rate higher during a deficit.
5. Audit your portions. After several weeks, portion sizes tend to drift upward. Weigh your food for a few days to recalibrate.

When 2 Pounds Per Week Is Too Much

This rate of loss isn’t right for everyone. Slow down if:

• You’re already at a relatively lean body composition (under 25% body fat for women, under 18% for men)
• You have a history of eating disorders or disordered eating
• Your calculated calorie target falls below the minimum safe threshold
• You’re experiencing persistent fatigue, hair loss, or loss of menstrual periods
• You’re under 18 or over 70

A slower rate of 0.5 to 1 pound per week preserves more muscle, feels more sustainable, and cuts the risk of rebound weight gain. The best deficit is the one you can actually maintain for months.

Here’s What It Comes Down To

To lose 2 pounds per week, create a 1,000-calorie daily deficit from your TDEE, keep protein high, and never drop below minimum calorie floors. Track your intake, weigh food when you can, and recalculate your targets every 10 to 15 pounds lost. And if the pace feels unsustainable? Slow down. Losing 1 pound per week for a year beats losing 2 pounds per week for three weeks and then giving up.
