Calorie deficit for weight loss: Does it work? effective tips, dos and don'ts
PTC Web Desk: Maintaining a calorie deficit is one of the most widely recommended methods for weight loss. The concept is straightforward: consume fewer calories than your body requires to maintain its current weight. This deficit forces the body to use stored fat as energy, resulting in weight loss over time. But how effective is it, and what’s the best way to practice it? Here's what you need to know.
What is a calorie deficit?
A calorie deficit occurs when you consume fewer calories than your Total Daily Energy Expenditure (TDEE). TDEE is the total number of calories your body burns in a day, including basic metabolic functions, physical activity, and digestion.
For example, if your TDEE is 2,000 calories and you consume 1,500 calories daily, you have a deficit of 500 calories. Over time, this deficit can lead to fat loss, as the body uses stored energy to make up the shortfall.
Does calorie deficit work?
Yes, calorie deficit works, but its success depends on consistency, the size of the deficit, and overall diet quality. A moderate calorie deficit of 500-750 calories per day is often recommended for sustainable weight loss of 0.5-1 kg per week.
Extreme deficits, while tempting, can lead to muscle loss, fatigue, and nutritional deficiencies. Additionally, the body adapts to prolonged deficits by slowing down metabolism, making further weight loss challenging.
Effective ways to practice a calorie deficit
Track Your Calories: Use apps to monitor your daily intake and ensure you're in a deficit.
Increase physical activity: Combine a calorie deficit with exercise to create a larger energy gap without drastically reducing food intake.
Eat nutrient-dense foods: Prioritise whole, unprocessed foods like vegetables, fruits, lean proteins, and whole grains to feel full with fewer calories.
Practice portion control: Use smaller plates, measure serving sizes, and avoid eating directly from large packages.
Stay hydrated: Sometimes, thirst can be mistaken for hunger. Drinking enough water can prevent unnecessary snacking.
Dos and don’ts for a calorie deficit
Plan balanced meals with all macronutrients (protein, fats, carbs).
Listen to your body and eat when genuinely hungry.
Include regular strength training to preserve muscle mass.
Monitor progress and adjust calorie intake as needed.
Don’ts
Don’t rely solely on crash diets or drastic calorie cuts.
Avoid skipping meals, as this may lead to overeating later.
Don’t consume empty calories from sugary drinks or junk food.
Don’t ignore signs of fatigue, dizziness, or excessive hunger.
