The quest for rapid weight loss often leads individuals to explore various diet plans, with the "military diet" being one such popular option. Also referred to as the "soldier diet," this plan is characterized by its promise of quick results through a very low-calorie eating regimen. This article dissects the marine corps diet plan, scrutinizing its claims, potential benefits, risks, and sustainability, while incorporating general nutritional advice applicable to military personnel and anyone seeking a healthier lifestyle.
Understanding the Military Diet
The military diet is a three-day eating plan with strict calorie limits, followed by four days of less restrictive eating. Julie Rothenberg, RD, notes the diet often claims a 10-pound weight loss in a week. Contrary to its name, the military diet has no official connection to the armed forces or its dietary principles. The name implies the perseverance required to endure extreme calorie restriction.
How the Military Diet Works
This diet involves drastically reducing calorie intake for three days. While no "boot camp" is required, scaling back on exercise might be necessary due to potential dizziness or weakness from calorie cutting. Daily walks are often encouraged.
Potential Benefits and Sustainability
Short-Term Weight Loss
Vanessa Imus, RDN, explains that weight loss occurs when calorie intake is less than the body's daily needs. Severely cutting calories can lead to rapid weight loss but is often unsustainable.
Health Improvements from Modest Weight Loss
The CDC reports that losing just 5% of body weight can improve health and reduce the risk of chronic conditions like heart disease, prediabetes, and diabetes.

The Challenge of Long-Term Weight Management
A 2019 study revealed that dieters are more likely to gain weight over time than those who don't diet. This highlights the difficulty of maintaining weight loss through restrictive plans like the military diet.
Potential Disadvantages and Risks
Health Risks of Rapid Weight Loss
Rapid weight loss can lead to loss of muscle mass and tissue supporting the skeletal system, increasing the risk of osteoporosis. Nutrient deficiencies can also occur, which multivitamins cannot fully compensate for. Electrolyte imbalance, hormone shifts, and organ damage are also potential adverse effects.
Calorie Restriction and Nutritional Needs
The military diet often recommends as few as 1,100 calories, which may not meet daily nutritional needs. The Dietary Guidelines for Americans recommends 1,600 to 2,200 calories per day for women ages 31 to 59 and 2,200 to 3,000 calories per day for men in the same age range. Individual calorie needs vary based on factors like sex, body weight, and activity level. Consulting a doctor or dietitian is advised for creating a suitable low-calorie diet.
Risk of Binge Eating
Restrictive diets may lead to binge eating habits. Imus notes that over-restricting calories can cause individuals to eat large amounts of previously denied foods, leading to rapid weight regain. Studies show that calorie deprivation increases food cravings and the likelihood of disordered eating, potentially causing adverse effects such as high blood pressure, diabetes, cardiovascular disease, and sleep disorders.

Tips for Starting the Military Diet
- Keep Expectations Realistic: Weight loss may occur, but long-term weight management is unlikely. Have a plan to transition to a healthier eating pattern.
- Balance Your Macros: Ensure a balance of healthy carbohydrates, lean proteins, and healthy fats in every meal.
- Listen to Your Body: Pay attention to how you feel. If you experience lightheadedness, dizziness, nausea, or fatigue, consider an alternative weight loss method.
- Be Prepared for Challenge: The diet requires significant discipline due to substantial calorie reduction.
- Stick to Only Light Exercise: High levels of activity may be too taxing during the calorie-restriction phase.
Nutritional Guidance for Military Personnel
Marines need to consume adequate calories to support high-intensity or long-duration training. Dietary protein is required to promote growth, repair damaged cells and tissue, synthesize hormones, and for a variety of metabolic activities. Recommended protein intakes for tactical athletes can be met through diet alone without the use of protein supplements. It is generally recommended that protein intakes fall within 1.2 - 1.7 gm/kg (0.5 - 0.8 gm/lb.) bodyweight for tactical athletes depending on type and amount of physical activity.
Fat is a source of energy, provides essential fatty acids, carries fat soluble vitamins and is an important nutrient for tactical athletes. The focus should be placed on including monounsaturated fats (olive oil, canola oil, nuts and seeds, natural peanut butter, avocado and fatty fish like salmon) while limiting saturated fats (butter, high fat red meat, fried foods, hydrogenated and trans fats, desserts, cheese and other whole fat dairy) in the diet.
Water and hydration levels are critical for maximum performance. Hydration plays a critical role in regulating body temperature, carrying nutrients throughout the body and eliminating waste and toxins. Just small amounts of dehydration can greatly affect performance. A 150 lb. athlete with a water loss of just 3 lb. can have reduced performance by 10 - 20% and his effort will feel harder than normal. With a water loss of just 4½ pounds reaction times, judgment, concentration and decision making ability are negatively affected. Temperature regulation and brain function are also impaired. It is recommended that tactical athletes drink half their body weight (lb.) in ounces of water at a minimum, not counting exercise.
Carbohydrates are the body's main source of energy. Carbohydrates maintain blood glucose during exercise and replaces muscle glycogen after exercise. Choosing high quality carbohydrates (fruits, vegetables, beans, brown rice, whole wheat breads, pasta and other grains), and limiting refined, processed carbohydrates (white bread, white rice, cookies, cakes, chips and other junk food) gives the body the best fuel while maintaining blood glucose levels. Besides water, carbohydrates are the most limiting factor of physical performance and the amount and timing of carbohydrate ingestion is imperative for best functioning.
Marine Corps Nutrition
In order to maximize your physical performance, your diet should consist mostly of lean proteins, garden vegetables, especially green leafy ones, nuts and seeds, some healthy starches, and no sugar. A good general rule of thumb is to stay on the perimeter of the grocery store (where most of the fresh meats and produce are), while avoiding the aisles (where you will find most of the packaged, processed, and chemically preserved items).

In most cases, the longer the shelf-life, the more chemicals have been put into it, the worse it is for your body’s physical performance. In general you should think of your nutritional intake as broken down into three categories, or micronutrients: Carbohydrates, Proteins, and Fats.
Carbohydrates are easily used by the body for energy. Your carbohydrates should consist of mostly green leafy vegetables, other assorted veggies, some fruits, and some whole grains. Examples of good carbohydrates: Lettuce, spinach, broccoli, asparagus, sprouts, celery, onions, peppers, tomatoes, salsa, berries, grapes, apples, oranges, pineapples, plum, watermelon, whole wheat bread, oatmeal, whole grain pastas.
Protein is important for growth and preserving lean muscle mass. Your proteins should consist of mainly lean meats with low saturated fat content cooked on a grill, stove, or oven. Avoid fried meats or meats covered in breading or sauces with high sugar/salt content. Examples of good proteins: Chicken breast, turkey breast, ground turkey, lean beef, fish, seafood, turkey sausage, tofu, eggs, cheese.
Fat is the most concentrated source of energy. Your fats should consist of items with very little to no trans-fat, low in saturated fat, and high in unsaturated, monounsaturated, and polyunsaturated fats. Examples of good fats: Almond, avocado, canola oil, macadamia nuts, olives, peanut butter, almond butter, guacamole, sunflower seeds, extra virgin olive oil, light mayonnaise.
Dietary Guidelines for Optimal Fitness
Nutrition is a critical factor in enhancing athletic performance, injury prevention, recovery, and resilience. The appropriate selection of foods and fluids, proportions of macronutrients, and timing of when ingested are important for maximum performance.
Achieving Weight Loss Goals
Alexander Klopfenstein, who lost 83 pounds to meet Marine Corps standards, relied on a low-fat diet and regular exercise. Key strategies included:
- Avoiding Refined Carbohydrates: Breads, pastas, and tortillas were eliminated.
- Exercising Consistently: Strength training and cardio were performed regularly.
- Getting a Workout Buddy: Teaming up with someone provided motivation and support.
- Avoiding Red Meat: Fish and chicken provided protein with fewer calories.
- Cutting Dairy: Limiting high-fat dairy products.
- Prioritizing Transformation: Making fitness a priority.
- Learning Smart Ways to Workout: Combining pull-up workouts with push-ups and burpees.
Beth Moylan, a senior nutritionist, advised that no more than two pounds should be lost per week. Meeting with a professional after achieving weight loss goals is crucial for maintaining a steady weight.
