“How many calories should I eat to lose weight?” sounds like a question that should have a simple number as an answer. It doesn't. Daily energy needs vary according to factors such as age, sex, body size, metabolism, and physical activity. Two people can therefore have very different calorie needs even if their current weight is similar. A more useful approach is to estimate how much energy your body uses each day and then create an appropriate calorie deficit. How Calories R

When people start losing weight, calories usually get most of the attention. But protein deserves attention too—especially if the goal is to lose fat while maintaining as much lean mass as possible. For many adults pursuing weight loss, a practical starting range is around 1.2–1.6 grams of protein per kilogram of body weight per day. That does not mean everyone needs the top end of the range. Your ideal intake depends on body size, activity level, age, health status, and how

If you're trying to lose weight, one of the first questions you may ask is: How many calories should I eat per day? There isn't one calorie target that works for everyone. Daily energy needs vary with body size, age, sex, metabolism, and physical activity. NIDDK notes that calorie needs can differ based on all of these factors, which is why individualized planning is more useful than assigning the same calorie intake to everyone. A practical place to start is your TDEE, or To

BMR and TDEE are two numbers you will often see in calorie calculators, fitness apps, and weight-management plans. They are related, but they do not mean the same thing. BMR describes the energy your body uses under basal resting conditions. TDEE describes the total amount of energy you use across an entire day. If your goal is weight loss, TDEE is generally the more useful starting point because it accounts for your overall daily energy expenditure rather than your resting n

Intermittent fasting, often called IF, has become a popular way to manage weight. One of the best-known methods is 16:8 fasting, where you fast for 16 hours and eat within an 8-hour window. But does intermittent fasting actually help you lose weight? The short answer is yes, it can help some people. However, IF is not a magic weight-loss method, and it does not always work better than other ways of eating less. Research available through 2026 shows that intermittent fasting c

When you're working toward a weight-management goal, rapid changes on the scale can feel rewarding. But losing weight too fast does not necessarily mean you're losing more body fat. Body weight includes fat, muscle and other lean tissue, glycogen, water, organs, and bone. During a large calorie deficit, the change on the scale can therefore come from several of these compartments. Very restrictive approaches may also make it harder to meet nutritional needs and can increase c

Eating out does not have to derail your weight-management goals. Restaurant meals, work lunches, family dinners, and social occasions can all fit into a healthy eating pattern. The goal is not to find a mythical restaurant meal that is guaranteed to be “weight-loss friendly.” Instead, focus on the overall combination of food choices, portions, drinks, sauces, frequency, and your eating habits over time. Portion size matters as well as food quality. Restaurant servings can som

Reaching a weight-loss goal is an important milestone, but it is not necessarily the end of weight management. The next phase learning how to maintain weight loss often requires a different approach. Weight regain is common and is not simply a matter of willpower. After weight loss, the body may require less energy at its new weight, while metabolic and hormonal changes can make maintenance more challenging. Successful maintenance is therefore less about continuing a restrict
