The Truth About Low Calorie Diets for Weight Loss

The Truth About Low Calorie Diets for Weight Loss

Losing weight often means cutting calories. After all, to lose weight you need to burn more calories than you consume. So it would make sense that the best way to accelerate weight loss is to drastically slash calories, right? Well, not so fast. When it comes to nutrition and weight loss, low calorie don't mean no calorie.

Why Cutting Calories Helps With Weight Loss

There's no doubt that creating a calorie deficit is key for shedding pounds. That means consuming fewer calories than your body burns each day. This forces your body to dip into its fat stores for energy. The higher the calorie deficit, the faster the weight comes off.

This is why low calorie diets often produce rapid weight loss in the beginning. When you severely restrict calories to just 800-1,200 per day, your body has no choice but to burn its fat for fuel. You'll see the numbers on the scale drop quickly at first.

The Downsides of Very Low Calorie Diets

While crash dieting may kickstart weight loss, it often leads to problems down the road. Here are some of the major risks and downsides of overly restrictive low calorie diets:

• Nutrient deficiencies - When calories are too low, it's nearly impossible to meet all your nutritional needs. This can lead to deficiencies in vitamins, minerals, protein, fiber and healthy fats.
• Muscle loss - Your body will burn both fat and muscle in response to drastic calorie cuts. Losing lean muscle mass slows your metabolism.
• Fatigue and weakness - You'll likely feel tired, dizzy and weak on a crash diet with calories below 1,200 per day. This makes daily activities difficult.
• Extreme hunger - Attempting to ignore intense hunger usually fails. Severe calorie restriction often leads to binge eating when willpower runs outs.
• Metabolic adaptation - Over time, your metabolism slows down in response to inadequate calories. This makes it harder to keep losing weight.
• Weight regain - Nearly all weight lost on very low calorie diets is gained back when normal eating resumes. It's unsustainable in the long run.

The Risks of Too Few Calories

Eating too little can actually stall your weight loss efforts. How low is too low when it comes to calories? While individual needs vary, most sources suggest avoiding crash diets below 1,200 daily calories.

Severely cutting calories to lose weight rapidly often backfires. You may see initial results on an 800-calorie diet. But as your body goes into survival mode, your metabolism slows down. Once you resume normal eating, weight regain is inevitable.

Very low calorie diets below 800 calories per day can be dangerous without medical supervision. Nutrition this inadequate makes it difficult to meet vitamin and mineral needs. It can also cause problems like an irregular heartbeat, dizziness, fatigue, nausea, and hair loss.

A Better Approach to Weight Loss

Instead of starvation diets, take a more balanced approach that's sustainable over time. Here are some healthier tips for successful weight loss:

• Cut calories moderately - Reduce daily calories by 500-750 below your maintenance level for loss of 1-2 pounds per week.
• Increase activity - Burn extra calories through exercise like brisk walking, cycling or strength training.
• Eat plenty of protein - Getting 30% or more of calories from protein boosts satiety and preserves muscle mass.
• Include fiber and healthy fats - These nutrient-dense foods provide satiation and energy for fewer calories.
• Drink water - Stay hydrated to prevent mistaking thirst for hunger.
• Manage stress - High cortisol levels can increase belly fat storage and calorie intake.
• Get enough sleep - Lack of sleep is linked to hunger and overeating, especially carbohydrates.
• Be patient - Steady weight loss of 1-2 pounds per week is more likely to stay off long-term.

The Bottom Line

There's no question that weight loss requires cutting calories. But with low calorie diets, less is not always better. Severe calorie restriction stresses your body and sets you up for failure in the long run.

Aim for moderate calorie cuts, increased activity and nutrition from whole foods. Be patient - slow and steady wins the weight loss race. Though the scale may not drop as dramatically each week, you'll stay healthier and be more likely to keep the weight off for good.

When it comes to calories for weight loss, low calorie don't mean no calorie. Moderation, exercise and nutrition are the keys to sustainable results.
