You can't lose a significant amount of pure fat in a single day; most rapid weight loss is water/glycogen, but a healthy, sustainable goal is losing 1-2 pounds (0.5-1 kg) per week, which requires a daily deficit of about 500-750 calories through diet and exercise. While extreme methods exist, they risk muscle loss and are unsustainable, making gradual fat loss the safest and most effective approach.
Yes, it's possible to burn 3000 calories a day. However, you'll have to take on some extreme measures to reach this number. For example, a 185-pound person can burn approximately 840 calories by running for an hour (3). To achieve 3000 calories in a day you'd have to run for nearly four hours.
Unless you are among the athletes whose rigorous training burns a massive amount of calories, you cannot burn 4,000 calories a day. Most women burn 1,600 to 2,000 calories a day and most men burn 2,000 to 3,000 calories per day, depending on factors such as age and activity level.
Scientifically, it may not be healthy, or safe, for many people to lose 1 kg of weight per day. But we are sharing some important tips and several strategies that can help you achieve safe and effective weight loss in the long term.
Adele's significant weight loss wasn't from a quick fix but a two-year journey combining intense strength training, Pilates, hiking, boxing, and cardio, alongside major lifestyle changes focused on managing anxiety, not restrictive diets like the Sirtfood Diet, with workouts happening multiple times daily for mental and physical strength. Her routine included morning weights, afternoon hikes or boxing, and evening cardio, emphasizing getting stronger, which naturally led to fat loss and improved well-being.
The 3-3-3 rule for weight loss is a simple, habit-based method focusing on three key areas: 3 balanced meals a day, 3 bottles (or ~1.5L) of water by 3 PM, and 3 hours of physical activity per week, aiming for consistency over complex diets. It simplifies fat loss by establishing rhythm through consistent eating, adequate hydration to support metabolism, and regular movement, promoting sustainable health without intense calorie counting or restrictive rules, says Five Diamond Fitness and Wellness, Joon Medical Wellness & Aesthetics, and EatingWell.
It is estimated that 10,000 steps burns 500 calories, so if weight loss, fat loss or body composition changes are a part of your goals.... you do not want to miss out on hitting your step goal everyday.
Consuming at least 1,200 calories per day has often been touted as the minimum for basic bodily functions and to stay out of starvation mode, but the amount is actually too low. A healthy amount of calories for adult women ranges from 1,800 to 2,400 calories per day and for men it's 2,000 to 3,200 calories per day.
In recent years, Zuckerberg's diet has evolved to support his physically demanding routines, such as MMA and jiu-jitsu training—sometimes reaching 4,000 calories a day, with high-protein, practical choices like lean meats and eggs, though he occasionally indulges in fast food or unique global offerings.
How Many Calories Do You Burn While You Sleep? As a very approximate number, we burn around 50 calories an hour. View Source while we sleep. However, every person burns a different amount of calories during sleep, depending on their personal basal metabolic rate.
If you consume more calories than your body needs over several days or weeks, that excess will be stored as body fat. However, an occasional cheat meal — even one that is high in calories — generally isn't enough to cause significant fat gain, as long as it remains infrequent and the rest of your week is well managed.
Resting calorie burn is the amount of energy your body uses even when you're not moving. It keeps essential functions like breathing, circulation, and temperature control running around the clock. This is why your body continues to burn calories even when you're sleeping, reading, or relaxing.
At 22% body fat, men often have a softer midsection, less muscle definition, and a healthy but not overly lean look, while women typically appear athletic and toned, with some ab definition visible when flexing and definition in arms and legs, sitting in the "fitness" or "average" range for both genders, though visual appearance varies by individual.

The 2-2-2 weight loss method is a simple strategy focusing on 2 big bottles of water, 2 servings of fruits/veggies, and 2 daily walks, promoting hydration, nutrient intake, and activity to kickstart weight loss, energy, and better sleep, acting as a foundation for healthier habits rather than a complete diet plan. It's easy to follow and encourages movement and nutrient-dense foods but doesn't cover total calorie intake or macronutrients, requiring it to be complemented with a holistic plan for sustainable results.
As a general rule though, most nutrition experts recommend never going below 1,000-1,200 calories a day if you're dieting on your own. It's also worth bearing in mind that the body doesn't suddenly 'enter' and 'leave' starvation mode, like crossing the border from Devon into Cornwall.
If you took the most calorically dense food you could find, perhaps olive oil to avoid saturated fats, you would need to consume 3.3 gallons to get your 100,000 calories. Assuming this was possible, you would overwhelm the lipid uptake capacity of your intestines and most of it would just pass straight through you.
Get enough B vitamins – B vitamins, in foods such as bananas, baked potatoes, eggs, orange juice, peanut butter, peas, spinach and whole-grain foods, are essential for a fully functioning metabolism. B vitamins help your body metabolize carbohydrates, proteins, and fats, and use the stored energy in food.
To lose 1kg (about 2.2 lbs) through walking, you generally need to burn around 7,700 calories, which translates to roughly 120,000 to 200,000 steps, depending on your pace and body weight, but achieving this healthily means aiming for 10,000+ steps daily as part of a consistent routine that also involves diet, leading to about 0.5-1kg loss per week. A daily goal of 10,000 steps burns 300-400 calories, while 15,000-18,000 steps burns 500-700 calories, making 1kg loss a gradual, multi-week process, not a single burst of steps.
According to Sam Quinn, Personal Training Lead at Nuffield Health, consistently walking 20,000 steps per day can: Improve cardiovascular endurance. Burn significant calories and support healthy weight management. Boost metabolic health by helping to regulate blood sugar and cholesterol.
Pick up the pace
In fact, researchers investigating walking pace found that a faster habitual walking pace may be causally related to longer leucocyte telomere length (LTL), an indicator of biological age, which could explain some of the beneficial effects of brisk walking on health status.
Some of the ways she's lost weight include walking, eating more protein, and medication to help with how her body processes food. Clarkson started some of these changes to her diet and exercise routines when she moved to New York City, where she hosts "The Kelly Clarkson Show."
Her diet included meals like vegetable poha, fruit, roti, and grilled chicken. Alia trained with Yasmin Karachiwala, blending Pilates, cardio, and strength exercises. Her 7-day routine included running, push-ups, yoga, squats, and crunches to tone and lose weight.
According to fitness coach Raj Ganpath, losing 10 kg in 2-3 months is possible but highly unsustainable. He explains that to achieve this, you need a daily calorie deficit of about 1,300, which is extremely difficult to maintain.
