Basal metabolic rate (BMR) is often used interchangeably with resting metabolic rate (RMR). While BMR is a minimum number of calories required for basic functions at rest, RMR — also called resting energy expenditure (REE) — is the number of calories that your body burns while it’s at rest.

A low BMR means you have to eat less calories in order to lose body fat and weight. The Metabolic age is calculated by comparing your Basal Metabolic Rate to the average BMR of your chronological age group. If your metabolic age is higher than your actual age, it’s an sign that you need to improve your metabolic rate.

An average man has a BMR of around 7,100 kJ per day, while an average woman has a BMR of around 5,900 kJ per day. Energy expenditure is continuous, but the rate varies throughout the day.

Going too low delivers a double whammy to your metabolism. When you eat less than you need for basic biological function (about 1,200 calories for most women), your body throws the brakes on your metabolism.

A 500-calorie diet is an extreme form of a very low-calorie diet (VLCD). It requires you to drastically reduce the amount of food you eat, usually to a maximum of 800 calories per day. VLCDs use meal replacements like drinks, shakes, and prepared food bars instead of meals for at least two meals a day.

Here are 13 low-calorie foods that are surprisingly filling.

• Greek Yogurt. Greek yogurt is a great source of protein that can help curb cravings and promote weight loss.
• Soup.
• Berries.
• Eggs.
• Popcorn.
• Chia Seeds.

In addition, consuming as few as 800 calories daily may not give you the energy you need for daily living and regular physical activity, especially if you eat the same foods every day. Talk to your doctor or dietitian to make sure you get the nutrients you need while on a very low-calorie diet.

Consuming 500 calories a day is not a healthy diet. Normally, eating anything below 1200 calories per day will make your body assume there’s a food shortage. The end result will cause your body to go into what is known as “Starvation Mode”. During this mode, your metabolism will slow down and try to conserve energy.

During this period of the diet, it’s advised you enjoy fewer processed and more home-cooked foods, with plenty of vegetables and fruit as well as whole grains, beans, lentils, extra fibre, lots of nuts and plenty of full-fat dairy and oily fish.

“Your true weight is based on your body stores, and only decreases when your energy intake is less than the energy you’re burning,” says Charlotte Martin, MS, RDN, CSOWM, CPT. Meaning, of course, your weight changes when you eat differently and you exercise more. So the weight loss from pooping is incredibly temporary.

In order to lose at least a pound a week, try to do at least 30 minutes of physical activity on most days, and reduce your daily calorie intake by at least 500 calories. However, calorie intake should not fall below 1,200 a day in women or 1,500 a day in men, except under the supervision of a health professional.

The 1,500-calorie diet is a diet plan that people may try when attempting to lose weight. By eating fewer calories and exercising regularly, people can create a calorie deficit, which can lead to weight loss. Some people may choose to restrict their daily intake to 1,500 calories.

Your 3-Day Heart-Healthy Meal Plan: 1,200 Calories

• Day 1. Breakfast: 2 large eggs, 2 slices whole grain bread, 1 Tbsp. olive oil spread.
• Day 2. Breakfast: 1 cup oatmeal, ½ cup blueberries, 1 Tbsp. peanut butter.
• Day 3. Breakfast: 1 cup fat-free cottage cheese, ½ cup fresh pineapple. Lunch: 3 oz.

When you space out your meals too much, your metabolism slows down and isn’t able to burn off all the calories you eat in your next meal. Those extra calories may wind up as extra weight. And you may overeat because you’re too hungry. Try eating smaller portions, and eat more often.

Creating a calorie deficit is necessary for weight loss. Cutting calories by 500–750 calories per day, as some health professionals advise, is likely to encourage weight loss, at least in the short term. Many studies have shown that following low calorie diets, including 1,200-calorie diets, can promote weight loss.

Generally to lose 1 to 2 pounds a week, you need to burn 500 to 1,000 calories more than you consume each day, through a lower calorie diet and regular physical activity. Depending on your weight, 5% of your current weight may be a realistic goal, at least for an initial goal.

And if you eat fewer calories and burn more calories through physical activity, you lose weight. In general, if you cut 500 to 1,000 calories a day from your typical diet, you’ll lose about 1 pound (0.5 kilogram) a week. It sounds simple.

High-fiber foods not only provide volume but also take longer to digest, making you feel full longer on fewer calories. Vegetables, fruits and whole grains all contain fiber. Popcorn is a good example of a high-volume, low-calorie whole grain.

The Fast 800 diet, created by Dr Michael Mosley, is a new iteration of his 5:2 diet. It encourages people to eat 800 calories per day, fast intermittently and replace some meals with nutritious shakes. Dr Molsey recommends eating 800 calories a day for a minimum of two weeks but can follow the plan for longer.

Yes, if following F-Factor correctly, people can eat unlimited vegetables and still lose or maintain weight—so long as they are non-starchy vegetables that are raw, plain or steamed with no oil (as opposed to being prepared with butter, oil or sauce).

Meat doesn’t have fibre, nor does it have key vitamins and nutrients. Fruits and vegetables may have vitamins, but they don’t have anywhere close to enough fat or protein, even eaten in quantity. The body does not need as much as you might think to stay alive, but you omit them at your peril.

Most fruits are low in calories while high in nutrients and fiber, which can boost your fullness. Keep in mind that it’s best to eat fruits whole rather than juiced. What’s more, simply eating fruit is not the key to weight loss. You should also strive for a healthy, whole-foods-based diet alongside physical activity.

Here are 11 foods to avoid when you’re trying to lose weight.

• French Fries and Potato Chips. Whole potatoes are healthy and filling, but french fries and potato chips are not.
• Sugary Drinks.

• Pastries, Cookies and Cakes.
• Some Types of Alcohol (Especially Beer)

11 Best Low-Sugar Fruits

• Grapefruit.
• Avocado.
• Watermelon.

Low-sugar fruits include:

• Strawberries. Strawberries, like many other berries, are often high in fiber and contain very little sugar.
• Peaches. Although they taste sweet, a medium sized peach only contains around 13 g of sugar .
• Blackberries.
• Lemons and limes.
• Honeydew melon.
• Oranges.
• Grapefruit.
• Avocados.

Fruit contains natural sugars, which are a mix of sucrose, fructose and glucose. Many people have heard that sugar is bad, and think that this must also therefore apply to fruits. But fructose is only harmful in excess amounts, and not when it comes from fruit.

Including whole fruits in a no-sugar diet can still be healthful. However, if a person chooses to eat dried fruit, they should do so in moderation and look for varieties without added sugar.

Unless you are following a ketogenic diet or have some sort of intolerance, there really is no reason to limit the amount of fruit you eat. While most studies suggest that the optimal amount is two to five servings of fruit per day, there seems to be no harm in eating more.

But for healthy adults, experts say that eating lots and lots of fruit is unlikely to get you into trouble, as long as it’s part of a normal diet. The main concern with overeating fruit is its natural sugar.
