CDC healthy weight losing weight 1 to 2 pounds per week physical activity strength training guidelines adults

At 5'3" and 139 lb, a goal of 105 lb is a 34 lb reduction. That weight is a BMI of about 18.6, which is still in the standard healthy range but close to its lower boundary. Make body composition, strength, energy, and menstrual regularity equal priorities with the scale number.

A realistic fat-loss pace while preserving or gaining muscle is 0.5 to 0.75 lb per week. Expect roughly 10 to 16 months, with early progress sometimes faster and later progress slower. Gradual loss is more likely to be maintained, according to the CDC guidance on weight loss.

1. Calorie target

Because age and current activity level are unknown, start with an estimate and adjust from actual results.

Start at 1,500 to 1,650 calories/day for 2 to 3 weeks.
Do not routinely go below 1,300 to 1,400 calories/day without clinician or registered-dietitian supervision.
Track body weight daily or 3 to 4 times weekly, then use the weekly average.
Target average loss: 0.5 to 0.75 lb/week.
- Losing more than 1 lb/week for 2 to 3 weeks, feeling weak, unusually hungry, or seeing strength decline: add 100 to 150 calories/day.
- No loss for 3 consecutive weeks despite accurate tracking: reduce by 100 to 150 calories/day, or add activity.

Do not continuously cut calories as weight drops. Use small changes, one at a time.

2. Macros for fat loss with muscle retention

Daily targets

Nutrient	Target	Why
Protein	100 to 120 g	Supports muscle retention and training recovery
Fat	45 to 60 g	Helps satiety and hormonal health
Carbohydrate	Remainder of calories, often 130 to 190 g	Fuels lifting, walking, and daily energy
Fiber	25 to 30 g	Fullness and digestive health
Water	2 to 3 L, more with sweating	Hydration and exercise performance

Aim for 25 to 35 g protein at each meal, spread across 3 to 4 meals. Resistance training is specifically designed to promote muscle hypertrophy, while diet and exercise together work better for fat loss than either approach alone.

Good protein choices

Chicken, turkey, lean beef, fish, shrimp
Eggs and egg whites
Greek yogurt, cottage cheese, milk or soy milk
Tofu, tempeh, edamame, beans, lentils
Protein powder if it makes meeting protein easier

High-volume foods

Build most meals around:

Vegetables: leafy greens, broccoli, zucchini, peppers, carrots, green beans
Fruit: berries, apples, oranges, bananas
High-fiber carbohydrates: potatoes, oats, rice, whole-grain bread, quinoa, beans
Fats in measured portions: olive oil, avocado, nuts, nut butter, cheese

3. A simple 1,550-calorie day

Breakfast, about 350 calories

Greek yogurt bowl: 1 cup Greek yogurt, berries, ¼ cup oats, chia seeds
Approx. 30 g protein

Lunch, about 450 calories

Chicken or tofu bowl: 4 to 5 oz protein, rice or potato, large serving of vegetables, salsa or light dressing
Approx. 35 g protein

Snack, about 200 calories

Protein shake and fruit, or cottage cheese with berries
Approx. 20 to 25 g protein

Dinner, about 500 to 550 calories

Salmon, lean beef, chicken, tofu, or beans
Potato/rice/pasta portion
Large salad or cooked vegetables
Measured olive oil, avocado, or cheese
Approx. 30 to 35 g protein

Flexible adherence rules

Follow an 80 to 90% minimally processed-food pattern, not a rigid “perfect” diet.
Include favorite foods in planned portions. A weekly dessert or restaurant meal can fit.
Limit liquid calories, frequent alcohol, grazing, and large untracked cooking oils, sauces, and snacks.
Do not “earn” food through exercise or compensate after a higher-calorie meal. Resume normal eating at the next meal.

4. Strength-training plan

For muscle gain or retention, make lifting the priority. Train 3 days per week to start, then move to 4 only if recovery is good.

Training rules

Start each exercise with a weight that leaves about 2 to 3 repetitions in reserve. You should feel challenged but able to maintain form.
Use 2 to 3 sets per exercise for the first month.
Most exercises: 8 to 12 reps. Core and smaller movements: 10 to 15 reps.
Rest 1 to 2 minutes between sets.
When you reach the top of the rep range with good form on every set, add a small amount of weight or 1 to 2 repetitions next session.
Keep a workout log.

Weeks 1 to 4: three full-body days

Monday - Workout A

Goblet squat or leg press - 3 x 8 to 12
Romanian deadlift with dumbbells - 3 x 8 to 12
Dumbbell bench press or push-ups - 3 x 8 to 12
Seated cable row or one-arm dumbbell row - 3 x 8 to 12
Dumbbell shoulder press - 2 x 8 to 12
Plank - 3 x 20 to 45 seconds

Wednesday - Workout B

Reverse lunge or split squat - 3 x 8 to 10 each leg
Hip thrust or glute bridge - 3 x 10 to 15
Lat pulldown or assisted pull-up - 3 x 8 to 12
Incline dumbbell press or machine chest press - 3 x 8 to 12
Lateral raise - 2 x 12 to 15
Dead bug or cable Pallof press - 3 x 10 to 12 each side

Friday - Workout A
Next week, perform B-A-B. Continue alternating.

Weeks 5 onward: optional four-day upper/lower split

Lower 1: squat/leg press, Romanian deadlift, hip thrust, calves, core
Upper 1: bench press, row, shoulder press, pulldown, arms
Lower 2: split squat, hamstring curl, glute bridge/hip thrust, leg extension, core
Upper 2: incline press, row, pulldown, lateral raise, arms

Keep sessions to about 45 to 70 minutes. More is not automatically better. Consistent progressive training is.

5. Cardio and daily movement

Walking is highly useful because it raises calorie expenditure without interfering much with lifting recovery.

Weekly target

Begin at 7,000 to 8,000 steps/day.
Build gradually toward 8,000 to 10,000 steps/day, if sustainable.
Add 2 to 3 cardio sessions weekly:
- 20 to 35 minutes brisk walking, incline treadmill, cycling, swimming, or easy jogging
- Keep most cardio at a pace where conversation is possible

Adults should get at least 150 minutes weekly of moderate aerobic activity plus muscle-strengthening activity on at least two days, according to the CDC adult activity recommendations. For this goal, strength work 3 days weekly plus walking is a good starting structure.

Avoid making HIIT the main tool. If you enjoy it, use no more than 1 short session weekly while in a calorie deficit.

6. Timeline and checkpoints

Months 1 to 2: establish consistency

Expected scale trend: 4 to 6 lb down

Learn calorie and protein tracking.
Lift 3 times weekly.
Reach a stable daily step habit.
Focus on correct form, not maximal weights.

Months 3 to 6: primary fat-loss phase

Expected trend: another 8 to 12 lb down

Continue slow progressive overload.
Maintain protein.
Adjust calories or steps only after 3 weeks of a genuine plateau.
Take waist, hip, thigh, and progress photos every 4 weeks.

Months 7 to 10: reassess at roughly 115 to 120 lb

Expected trend: another 6 to 10 lb down

Fat loss normally slows as body weight falls.
Consider a 1 to 2 week maintenance-calorie break if dieting fatigue, persistent hunger, poor sleep, or declining workout performance occur.
Assess whether 105 lb still fits your health, strength, and appearance goals.

Months 10 to 16: final phase or maintenance

Expected trend: approach 105 to 110 lb, depending on response and body composition.
At this point, gaining muscle may make the scale less informative. Someone at 110 lb with more muscle, good strength, normal energy, and a smaller waist may look leaner and be healthier than at 105 lb after an aggressive cut.

7. How to track progress properly

Use all of these, not only the scale:

Weekly average body weight
Waist circumference at the navel, monthly
Hip circumference, monthly
Front, side, and back photos in the same lighting, monthly
Strength log: reps and load for squats/leg press, hinges, presses, rows
Energy, sleep, hunger, and menstrual-cycle regularity

The goal is fat loss while maintaining or improving strength. If strength is steadily falling, recovery and food intake may be too low.

8. Recovery habits

Sleep: 7 to 9 hours nightly
Rest: at least 1 full day without hard training weekly
Stress: use walks, stretching, social time, journaling, or relaxation routines
Deload: every 6 to 8 weeks, reduce lifting volume by about one-third for a week if joints are sore or performance is declining

9. When to pause and seek clinical advice

Get individualized guidance before aggressive dieting or training if you are pregnant, breastfeeding, under 18, have a history of an eating disorder, take diabetes or weight-related medication, or have a medical condition affecting exercise or nutrition.

Pause the calorie deficit and contact a clinician if you develop:

Missed or irregular periods
Persistent dizziness, fainting, extreme fatigue, or feeling cold
Hair loss, recurrent injuries, or worsening mood
Obsessive food/exercise thoughts
Rapid, unplanned weight loss

Best starting prescription: 1,550 calories/day, 105 to 115 g protein/day, three full-body strength sessions, 7,000 to 8,000 daily steps, and two easy cardio sessions. Run it for 3 weeks, judge the weekly-average trend and gym performance, then adjust conservatively.
