Best Weight Loss Diet Calories, Macros and Meal Plans

A good weight loss plan is more than a calorie number. You need enough protein to protect lean muscle, smart carbs for energy, and the right fats and fiber to stay full. This guide shows you how to set calories, convert them to macros, and turn the math into meals you can cook on a busy weeknight or order at a restaurant. You will see practical examples at several calorie levels, plus adjustments for different diets and schedules. If you are new to the topic or want a refresher on the fundamentals, review our overview of safe weight loss fundamentals before diving in. Then come back here for the step-by-step details and sample meal structures. By the end, you will understand what to eat, how much, and how to make it work in the real world without white-knuckle hunger or guesswork.

How many calories to lose weight

Calories set the ceiling. Macros and food choices determine how easy it is to live under that ceiling. The simplest place to start is your Total Daily Energy Expenditure (TDEE), which is the energy you burn through resting metabolism, movement, and exercise. You can estimate TDEE using a calculator or a quick rule: multiply your current body weight (in pounds) by 13–15 depending on activity (13 for mostly sedentary, 15 for very active). Someone at 170 pounds who lifts twice per week and walks daily might land near 170 × 14 ≈ 2,380 calories. From there, create a moderate deficit of 300–500 calories per day. That range supports a typical loss rate of 0.5–1.0 percent of body weight per week without aggressive hunger or performance crashes. If you prefer kilograms, multiply body weight by 29–33. A 77-kg person with moderate activity might maintain around 77 × 31 ≈ 2,387 calories. Subtracting 400 gives a target near 1,950 calories. All estimates are starting points; your weekly averages will tell you what is actually happening. If weight stalls for two to three weeks while adherence is solid, adjust downward by 100–150 calories or add a small, sustainable bump in daily steps. A practical floor matters. While there is no universal minimum, most adults do best staying above roughly 1,200 calories for women and 1,500 for men unless guided by a clinician. Very low intakes increase fatigue, nutrient gaps, and rebound risk. If a large deficit seems necessary, consider increasing daily movement instead—an extra 2,000–3,000 steps can meaningfully tilt your energy balance without cutting another meal. Tracking methods fall on a spectrum. On one end, detailed logging with a food scale gives clarity fast. On the other, plate-based approaches lean on structure: fill half the plate with nonstarchy vegetables, a quarter with lean protein, and a quarter with starches or grains, plus a thumb of fats. For many people, a hybrid works: log for two weeks to calibrate portions, then shift to plate visuals and repeatable meals that keep your average where it needs to be. Build your deficit around your calendar. If you socialize on weekends or have a heavy training day, you can bias more calories to those times while keeping the weekly average consistent. A simple approach is “budgeting” 100–150 extra calories on planned high-demand days and trimming the same amount on lighter days. Weekly loss still depends on the average, not any single day. Use feedback loops. Track three things: body weight (morning averages across the week), hunger (a 1–10 rating before meals), and performance (workout loads or pace). If weight is dropping faster than 1 percent per week and hunger is high, add 100–200 calories, usually from protein and high-fiber carbs. If weight is flat and hunger is low, you might be overestimating intake; tighten portions or adjust the target. When you want a deeper dive on setting a personalized calorie target based on age, height, activity, and timeline, see our breakdown of daily calorie targets.

Start near body weight (lb) × 13–15, or (kg) × 29–33.
Subtract 300–500 calories for a moderate deficit.
Aim to lose 0.5–1.0 percent of body weight per week.
Keep floors in mind (about 1,200–1,500+ calories for most adults).

Macros for fat loss

Once calories are set, macros decide how you feel and perform. In a calorie deficit, protein protects lean mass and tames hunger, carbs fuel training and daily movement, and fats support hormones and provide flavor and satiety. A sound starting split for many is: high protein, moderate carbs, moderate fats. But avoid rigid percentages without context—set protein first by body size, then fats, then fill the remaining calories with carbs. Here’s a step-by-step way to do it:

Set protein by body weight. Aim for 1.6–2.2 g per kilogram (0.7–1.0 g per pound). Choose a higher end if you are lean, older than 40, or training hard; the lower end suits higher-body-fat beginners. Protein yields about 4 calories per gram.
Set a healthy fat range. For most, 20–35 percent of calories is a good band. If you prefer a grams-per-kilogram rule, 0.6–1.0 g/kg is a reasonable minimum. Fat provides 9 calories per gram.
Allocate the rest to carbs. After protein and fats are set, use the remaining calories for carbs (4 calories per gram). Adjust toward carbs for hard training; shift toward fats if you prefer lower-carb meals and performance is fine.

Example at 1,900 calories (75-kg person):

Protein: 2.0 g/kg → 150 g = 600 calories.
Fat: 30% of calories → 570 calories ≈ 63 g.
Carbs: remaining → 1,900 − (600 + 570) = 730 calories ≈ 183 g.

Adjust by preference or training demands. Endurance blocks or leg day? Move 50–80 calories from fat to carbs. Appetite running hot? Nudge protein up by 10–20 g and swap refined carbs for higher-fiber options to smooth hunger curves without changing the calorie total. Meal distribution matters. Spread protein across three to five eating occasions, 25–45 g each. Pair carbs with activity windows: a carb-rich meal two to three hours pre-workout and a balanced meal after training support energy and recovery. Use fats to anchor meals with flavor and satiety. For sample macro splits at popular calorie levels and advice on choosing ratios that fit your goals, review our guide to macro ratios for weight loss. Back to top ↑

Protein targets by body weight

Protein is the anchor of a weight loss diet. It preserves lean tissue in a deficit, boosts satiety, and has the highest thermic effect of all macros. A practical daily target sits between 1.6 and 2.4 grams per kilogram of body weight (0.7–1.1 g per pound). Choose the higher end if you are leaner, older, or in a larger calorie deficit; choose the lower end if you have more body fat to lose or struggle to eat enough. Spread intake across the day. Most people do well with 25–45 grams per meal, plus a 20–30 gram snack if needed. Examples: 170 g Greek yogurt with whey stirred in; 120–150 g grilled chicken; 3 whole eggs plus egg whites; 150–200 g extra-firm tofu or tempeh; 1 cup cottage cheese. Use body-size math to set targets:

60-kg person: 1.8 g/kg → ~108 g per day. Three meals at ~30–35 g plus a 15–20 g snack works well.
80-kg person: 2.0 g/kg → ~160 g per day. Four meals at ~35–40 g plus a 20–30 g snack covers it.

Vegetarian or vegan? Combine legumes, soy foods, seitan, and high-protein grains like quinoa. Fortified plant-based yogurts and protein powders are convenient tools. Ensure B12, iron, calcium, and omega-3s. When you want a simple table of protein targets by weight class and ready-to-use food lists, use our resource on daily protein by body weight.

Build each plate around a palm-size lean protein.
Add a protein booster to low-protein meals.
Choose snacks that deliver at least 15–20 g protein.

Carbs that support weight loss

Carbohydrates are the body’s preferred fuel for moderate-to-high-intensity activity and an efficient vehicle for fiber, vitamins, and minerals. The right amount depends on activity, appetite, and preference. A practical band during weight loss is 2–5 g/kg of body weight per day, skewing higher for athletes and lower for sedentary days. If you are 75 kg and train three to four times per week, 200–250 g per day is a reasonable middle ground. Focus on quality. Choose slow-digesting, high-fiber sources most of the time—oats, brown rice, quinoa, whole-grain pasta, beans, lentils, potatoes, fruit, and starchy vegetables. Nonstarchy vegetables stretch meals without many calories. Timing tips. Many feel and perform better when they bias more carbs before and after training. On rest days, shift some carbs earlier if it helps with evening snacking. Refined sugar isn’t “poison,” but it crowds out better options and adds calories quickly. Use smart swaps: fruit with yogurt, dark chocolate squares, diet soda, flavored seltzer. Glycogen binds water, so higher-carb days can bump the scale. Use weekly averages and clothing fit to judge progress. For a simple daily carb target by body size and best sources per meal, check daily carb ranges.

Breakfast: oats with berries and whey; whole-grain toast with eggs and tomato.
Lunch: brown rice bowl with chicken and vegetables; lentil soup with whole-grain bread.
Dinner: salmon, potatoes, and a large salad; tofu curry with basmati rice.
Snacks: fruit, air-popped popcorn, edamame, high-fiber wraps.

Dietary fat for fullness and health

Dietary fat is calorie dense at 9 kcal/g, but it supports flavor, satiety, nutrient absorption, and essential fatty acids. A practical fat range during weight loss is 20–35% of total calories, with a floor around 0.6 g/kg most days. Source quality first. Favor unsaturated fats (olive oil, avocado, nuts, seeds, fatty fish). Include some saturated fat from whole foods while avoiding trans fats. Example: On 1,800 kcal, 25% fat ≈ 450 kcal ≈ 50 g per day. Distribute across meals for comfort and adherence. Measure oils and nut butters for two weeks to calibrate. Restaurant meals often hide fats in sauces—ask for them on the side. For a deeper look at choosing your fat target for fullness and health, see fat intake for satiety.

Cook with measured oils; finish with a flavorful drizzle.
Choose fatty fish twice per week.
Keep nuts and seeds portion-controlled.

Fiber, volume and hunger control

Hunger is biology. You can lower it without cutting more calories by engineering meals with more fiber and water. Most adults benefit from 25–38 g fiber per day (~14 g per 1,000 kcal). Pair fiber with lean protein to stretch fullness. Volumetrics: high-water, high-fiber foods have fewer calories per bite—salads, broth-based soups, fruits, steamed vegetables. Start meals with a low-calorie first course. Build plates:

Half the plate: nonstarchy vegetables.
Quarter: lean protein.
Quarter: smart carbs (beans, whole grains, potatoes, fruit).
Flavor add-ons: measured fats.

Strategic swaps: vinaigrettes over creamy dressings, pasta half-and-half with zoodles, Greek yogurt for sour cream, air-popped popcorn for chips. Hydration supports satiety. Keep “volume boosters” handy (frozen veg, salad mixes, microwave grains, canned beans). For more ideas, see high-volume, low-calorie foods.

Did your last meal include 25–40 g protein?
Was half your plate vegetables or fruit?
Did you drink water in the last hour?
Are you sleeping 7+ hours most nights?

Meal planning by calorie level

Translate calories and macros into repeatable meals. Create “default days” (e.g., training vs. rest) with 3–5 eating slots and a protein target per meal. Step 1 — Pick a meal frequency you can keep. Spread protein evenly (25–45 g each time). Step 2 — Assign protein first. Place protein across meals, then layer carbs and fats to hit calories. Step 3 — Build repeatable plates. Make 2–3 options per meal slot that meet the slot’s macro goals. Step 4 — Portion with visuals. Calibrate with a scale for two weeks; then use hand estimates. Sample day frameworks

~1,500 kcal: Yogurt bowl; tuna/bean salad; cottage cheese with fruit; chicken + potatoes + green beans.
~1,800 kcal: Eggs + toast; turkey & hummus wrap; protein shake + nuts; salmon + rice + broccoli.
~2,100 kcal: Oats + whey; chicken/lentil grain bowl; pre-training fruit; lean beef + potatoes + big salad; skyr.

Weekend/travel rules: keep breakfast identical; hit protein first; pre-log; carry a travel kit (protein, shaker, jerky, roasted edamame). Printable 1-week template: high-protein 7-day outline. One-hour weekend prep: weekend meal prep.

Decide your default day(s) by calorie level.
Pre-commit two options per meal.
Stock a protein, carb, and fat “booster” list.

High-protein breakfasts, lunches and dinners

A high-protein pattern makes weight loss manageable. Aim for 25–45 g per meal: “protein + produce + purposeful carbs + measured fats.” Breakfast (30–45 g protein)

Greek yogurt (300 g) + whey + berries + 15 g nuts.
Egg scramble (3 eggs + 150 g egg whites) + vegetables + whole-grain toast.
Protein oatmeal: oats in milk + whey; add banana or berries.
Tofu “eggs” with vegetables; whole-grain pita.
Cottage cheese bowl with pineapple, chia, cinnamon.

More templates: protein-rich breakfasts. Lunch (30–45 g; packable)

Big salad: 150–200 g chicken or tofu, beans, vegetables, olive oil & vinegar.
Sourdough sandwich (turkey, light cheese, crunchy veg) + yogurt.
Grain bowl: rice or quinoa, edamame or chickpeas, salmon or tempeh, pickled veg.
Soup + salad: lentil soup and tuna-veg side.

Dinner (35–50 g; high-fiber sides)

Sheet-pan chicken, potatoes, Brussels sprouts.
Salmon, farro, asparagus with lemon-tahini.
Lean beef & bean chili over baked potatoes.
Stir-fry with tofu, mixed vegetables, jasmine rice (measure the oil).
Pasta half-and-half (pasta + zucchini noodles) with turkey bolognese.

Fast evening options: easy high-protein dinners. Snack architecture (10–30 g protein)

Skyr or cottage cheese with fruit.
Protein shake with milk or fortified soy milk.
Jerky and an apple; roasted edamame; hummus and high-fiber crackers.
Mini wrap: high-fiber tortilla with turkey and mustard.

Flavor without calorie creep: acids & aromatics (citrus, vinegar, garlic, ginger, herbs, chili, mustard, capers). Measure oils/tahini. Batch-cook once, eat four ways: grill 1 kg chicken or tofu; roast vegetables; cook whole grains; portion for quick assembly. Plate formula recap

Start with a palm or two of protein.
Fill half the plate with vegetables.
Add a cupped hand of smart carbs (more if training).
Add a thumb of fats; taste, then add another if needed.

Eating out without derailing progress

Restaurants can fit if you control the big rocks—protein, vegetables, cooking method, and hidden fats. Before you go

Check the menu and pre-decide two options.
Eat a 20–30 g protein snack two hours beforehand.
Budget calories across the day.

At the table

Start with broth-based soup or shared salad (dressing on the side).
Choose grilled, baked, steamed, roasted; skip fried/heavy cream sauces.
Ask for sauces/dressings on the side; “fork dip.”
Pick potatoes, rice, or whole grains over creamy sides.
Split large mains or box half first.

Cuisine-specific plays

Italian: grilled fish/chicken, tomato sauces, minestrone, thin-crust pizza + salad.
Mexican: fajitas (extra veg), grilled fish tacos, black beans, pico, corn tortillas.
Chinese: steamed dumplings, lean stir-fries; request light oil; steamed rice.
Middle Eastern: kebabs, tabbouleh, fattoush, measured creamy dips.
Japanese: sashimi, yakitori, miso soup, rice; watch mayo rolls and tempura.

More Mexican picks: Mexican menu choices. Alcohol adds up (120–150 kcal per wine/beer; cocktails more). Choose lower-calorie options, alternate with water, set a cap. See alcohol and weight loss. Order scripts

“Grilled salmon with double vegetables instead of fries; dressing on the side.”
“Fajitas with extra peppers and onions; corn tortillas; beans instead of rice.”
“Stir-fry with chicken and mixed vegetables; steamed rice; light oil, please.”

The next day: return to your plan, hit protein, hydrate, and walk—no punishment. Back to top ↑

Intermittent fasting and other patterns

Intermittent fasting (IF) organizes eating windows (e.g., 16/8, 14/10). It helps if it reduces decision fatigue and evening snacking; calories and protein still rule outcomes. Design your window: match your training and social life (e.g., 11:00–19:00 for lunchtime training; 12:00–20:00 for social evenings). Macro priorities remain: 30–50 g protein per eating occasion; carbs near training; fats fill remaining calories. Evaluate hunger, energy, and sleep after two weeks. Adjust as needed. Detailed schedules: intermittent fasting schedules. Fasting window drinks: water, black coffee, plain/unsweetened tea, non-caloric electrolytes. Caution: not ideal for those with disordered eating history, pregnancy/breastfeeding, certain diabetes meds, or jobs needing steady intake—consult your clinician. Back to top ↑

Low-carb, keto, Mediterranean and plant-based

Multiple patterns can work when calories and protein are appropriate. Choose by preference, health context, and social fit. Lower-carb (not keto)

Macros: fewer starches, higher protein, moderate fat (e.g., 25–35% carbs, 30–35% protein, 30–40% fat).
Foods: eggs, fish, poultry, tofu/tempeh, yogurt; vegetables; fruit; measured legumes; starches around training.
Watch-outs: keep fiber up.

Ketogenic

Macros: very low carb (<50 g/day), high fat, moderate protein.
Foods: meat, fish, eggs, olive oil, avocado, nuts, nonstarchy veg; limited berries.
Watch-outs: constipation, social fit, high-intensity training. More: keto weight loss guide.

Mediterranean

Macros: flexible; produce, legumes, whole grains, olive oil, fish, fermented dairy.
Watch-outs: measure oils/nuts. See Mediterranean plan.

Plant-forward (vegetarian or vegan)

Macros: plan protein (1.8–2.4 g/kg via soy, legumes, seitan, fortified alternatives).
Watch-outs: B12, iron, calcium, iodine, omega-3s (consider algae oil).

Paleo-inspired

Macros: high protein, moderate fat, lower grains; focus on whole foods.
Watch-outs: avoid accidental too-low carbs; keep fiber up.

Performance lens: high-intensity work usually benefits from moderate carbs. If very low-carb, place carbs around training and lower intensity until adapted. Back to top ↑

Common mistakes and troubleshooting

Stalls are common; the fix is usually a small systems upgrade. Apply changes for two weeks, then reassess.

Protein too low: raise by 20–30 g/day with easy add-ons.
Liquid calories: swap soda for seltzer/diet; simplify coffee; cap alcohol.
Portion creep (oils/nuts/dressings): measure for two weeks; use single-serve packs.
Weekends erase weekdays: keep breakfast identical; pre-plan one restaurant meal; add a long walk.
Steps and sleep low: +2,000–3,000 steps; aim for 7–9 hours.
Scale noise: use 7-day averages; judge month over month.
All-or-nothing thinking: use a recovery script (protein + veg next meal, water, 15-min walk).

If fat loss pauses 2–3 weeks with good adherence, adjust minimally: −100–150 kcal/day or add a 20-minute walk after meals. See adjusting your deficit and stall-busting mistakes. Plateau protocol (14 days)

Recalibrate protein to 1.8–2.2 g/kg.
Measure fats & high-calorie condiments.
Add a pre-meal salad or broth soup to lunch and dinner.
Walk 10–15 minutes after two meals daily.
Tighten weekend structure (pre-log, drink caps).
Re-evaluate averages, photos, performance.

When to pause a cut: if persistently tired/cold/irritable or training regresses, maintain at TDEE for 2–4 weeks.
