Is 1400 calories enough to lose weight for male?

The number of calories needed for weight loss varies from person to person. However, a general guideline is that reducing daily calorie intake by 500–1000 calories per day can result in about 1–2 pounds (0.5–1 kg) of weight loss per week. For males, 1400 calories per day may be enough to lose weight, but it depends on factors like age, body size, activity level, and metabolic health.

What is Calorie Deficit?

Weight loss occurs when you consume fewer calories than your body burns in a day. This calorie deficit forces your body to break down stored fat for energy, resulting in weight loss over time.

To lose 1 pound of fat, you need a calorie deficit of about 3500 calories. This means reducing daily calories by 500 would lead to about 1 pound of fat loss per week (500 calories x 7 days = 3500 calorie deficit).

Daily Calorie Needs for Males

The number of calories needed per day varies between individuals based on factors like:


Younger adults generally need more calories than older adults. Calorie needs decrease as you age due to less muscle mass and lower activity levels.

Body Size

Larger and more muscular individuals need more calories than smaller individuals.

Activity Level

People who exercise regularly or have jobs involving physical labor need more calories than sedentary individuals.

According to the Dietary Guidelines for Americans, estimated daily calorie needs for males are:

Age Sedentary Moderately Active Active
19-30 years 2400-2600 calories 2600-2800 calories 3000 calories
31-50 years 2200-2400 calories 2400-2600 calories 2800-3000 calories
51+ years 2000-2200 calories 2200-2400 calories 2400-2800 calories

As you can see, active younger males need around 3000 calories per day, while sedentary older males may need only 2000 calories.

Is a 1400 Calorie Diet Safe for Men?

Eating only 1400 calories daily is considered very low calorie dieting for males. Some considerations:

  • A very low calorie diet can lead to nutritional deficiencies if calorie intakes are restricted for too long.
  • Rapid weight loss over 3-4 pounds per week is not recommended as it may cause muscle loss in addition to fat loss.
  • Lower calorie diets below 1500 calories should be monitored by a doctor and only followed for short periods.
  • Low energy intakes can leave you feeling tired, cold, and hungry which reduces quality of life.

So while 1400 calories may lead to fast weight loss for an overweight male, it may be difficult to maintain long-term due to both health risks and quality of life considerations.

What is a Healthy Rate of Weight Loss?

According to the Centers for Disease Control and Prevention (CDC), a healthy and sustainable rate of weight loss is 1-2 pounds per week. This equates to a calorie deficit of 500-1000 calories daily through diet and exercise.

Losing weight faster than 2 pounds weekly often causes loss of muscle mass and water weight rather than pure fat loss. It also increases risks of nutritional deficiencies, gallstones, and other side effects.

Steady weight reduction of 1-2 pounds weekly through a modest calorie deficit is ideal for maintaining energy levels and preserving muscle mass. This allows your body to adapt to the lower calorie intake for ongoing success.

Calorie Needs for Weight Loss in Men

A good starting point is to reduce your estimated daily calorie needs by 500-750 calories to lose about 1-1.5 pounds per week.

For example:

  • A moderately active 30 year old male with calorie needs of 2800 calories could aim for 2000-2300 daily calories to lose weight.
  • A sedentary 50 year old male needing 2200 calories could eat 1400-1700 calories for gradual weight loss.

However, the best calorie intake depends on the individual. Other factors like body size, metabolic factors, hunger levels, and ability to exercise should also be considered.

Working with a doctor, dietitian or nutritionist can help determine safe calorie deficits based on your health and body needs.

Sample Meal Plan for a Man Eating 1400 Calories

Here is a sample 1400 calorie meal plan for a male trying to lose weight:

Breakfast (300 calories)

– 1 cup oatmeal made with water (300 calories)
– 1 medium banana (105 calories)
– 1 tablespoon peanut butter (95 calories)
– 1 cup skim milk (90 calories)

Lunch (400 calories)

– Tuna salad made with 3 oz tuna, 2 tbsp light mayo, mustard, celery, lettuce on 2 slices whole wheat bread (400 calories)
– 1 medium apple (95 calories)

Dinner (500 calories)

– 3 ounces grilled chicken breast (140 calories)
– 1 cup roasted broccoli and carrots (60 calories)
– 1 cup brown rice (220 calories)
– Tossed salad with vinaigrette (80 calories)

Snacks (200 calories)

– 1 part-skim mozzarella cheese stick (80 calories)
– 3 cups air-popped popcorn (120 calories)

Nutrition Tips for a 1400 Calorie Diet

To meet all your nutritional needs on a 1400 calorie diet, here are some tips:

– Eat plenty of fruits and vegetables which are low in calories but high in vitamins and minerals.
– Choose lean proteins like chicken, fish, beans, eggs and Greek yogurt.
– Eat whole grains like oats, brown rice, quinoa and whole wheat bread for fiber.
– Include healthy fats like olive oil, nuts, seeds and avocado.
– Avoid empty calories from sugary drinks, desserts, fried foods, etc.
– Take a multivitamin to help cover any potential nutritional gaps.

Adding Exercise to a 1400 Calorie Diet

While you can lose weight from diet alone, adding exercise provides other benefits:

  • Burns extra calories to increase your daily deficit for faster weight loss.
  • Maintains or builds lean muscle mass which raises your metabolic rate.
  • Improves cardiovascular fitness and lowers heart disease risk.
  • Helps improve strength, mobility and balance.

Aim for 150-300 minutes of moderate exercise per week, like brisk walking, swimming or cycling. Weight training 2-3 times weekly is also recommended.

Potential Drawbacks of a 1400 Calorie Diet

While a 1400 calorie diet may cause fast short-term weight loss, potential downsides include:

  • Nutritional deficiencies if followed long-term without supervision.
  • Loss of lean muscle mass along with fat mass.
  • Feeling cold, tired and hungry from inadequate calories.
  • Yo-yo dieting due to rapid weight regain once you stop the diet.

Very low calorie diets below 1500 calories should only be followed for short periods under medical guidance. They are difficult to maintain lifelong.

Who Should Avoid a 1400 Calorie Diet?

Some individuals who should not follow a 1400 calorie diet include:

  • Teenagers and young adults who require extra calories to grow and develop.
  • Very active males with high calorie needs for sports performance.
  • Men who are underweight or have nutritional deficiencies.
  • Individuals with a history of eating disorders or disordered eating patterns.

Pregnant and breastfeeding women also have higher calorie needs for the health of their baby.


While eating 1400 calories per day may result in short-term weight loss for overweight men, it is likely too low for males long-term. A modest calorie deficit of 500-1000 calories daily, combined with more physical activity, is a safer path to sustainable weight loss over time.

Working with a healthcare professional can help determine appropriate calorie intakes tailored to your health status, body needs, and weight goals. The key is developing lifelong healthy eating habits, not just following a short-term quick fix diet.
