Cutting calories is the approach most dieters must take to meet their weight-loss goals. But every once in a while people take calorie restriction too far, ultimately making weight loss slower and more difficult by slowing your metabolism. Figuring out the right number of calories for you on a daily basis depends on your age, gender, and activity level. In general, the younger and more active you are, the more calories you can consume. And men are able to eat more calories daily than women. For example, the U.S. Department of Agriculture guidelines says that women 19 to 30 years old should consume 2,000 calories if they have a sedentary lifestyle or 2,400 calories if they have an active one; for men of the same age the range is 2,400 to 3,000 calories.

Defining the Low-Calorie Diet

It seems logical that if calories are the problem, you would want to eat as few of them as possible to speed weight loss. As a general rule, people need a minimum of 1,200 calories daily to stay healthy. People who have a strenuous fitness routine or perform many daily activities need more calories. If you have reduced your calorie intake below 1,200 calories a day, you could be hurting your body in addition to your weight-loss plans. “The big picture is to consume enough calories with a balance of nutrients and engage in physical activity for good health management to achieve one’s weight goals. Consuming less than 1,200 calories per day may make it difficult to meet vitamin and mineral needs via food,” says nutrition therapist Andrea Spivack, MA, RD, LDN, with Penn Behavioral Health at the University of Pennsylvania in Philadelphia. Tempting as it may be to continue with your low-calorie weight-loss plan and simply take a supplement, Spivack points out that there are some key nutrients which are only available through your diet. Occasionally, obese people will go on a very low-calorie diet — 800 to 1,000 calories per day — for a brief period of time in order to achieve a specific weight-loss goal, but then will switch to a diet with more calories to reach and maintain their desired weight. Such a diet is usually supervised by a doctor or nutritionist so that it is nutritionally balanced. Unfortunately, weight regain is common after these restricted calorie diets end.

Why Low-Calorie Diets Slow Your Metabolism

If you are on a very low-calorie diet, you may wonder why the numbers on your scale aren’t budging, but your diet buddy is slimmer by the month. The reality is that different people respond differently to low-calorie diets. When your body senses that food may not be in plentiful supply, it may slow down your metabolism as protection against the possibility of starvation, even if you are obese and deliberately trying to lose weight.

What part of the day does your body burn the most fat?

Timing. It is good to be aware of timing. We burn most calories in the late afternoon and early evening and the least in the very early morning. Most people burn about 10 per cent more calories between 4 p.m. to 6 p.m. Our body torches maximum calories at this time frame, regardless of what we do.

Great news for breakfast lovers! Eating breakfast is essential to keep our system in sync. After fasting for the entire night, our bodies get energy from breakfast to keep going throughout the day. If you keep eating your breakfast at different times or sometimes skip it, then it can make your internal rhythms less precise. What does slow your metabolism is eating too few calories. Even just a day or two of a very low-calorie diet can have this effect. So make sure you are taking in at least 1,200 to 1,500 per day. Try making breakfast and lunch your bigger meals. Research shows that people who eat the most of their calories later in the day tend to eat more calories, weigh more and have more body fat. A study published in the American Journal of Epidemiology found that people who eat 22 to 55 per cent of their total calories at breakfast gain 1.7 pounds over four years. That’s not bad considering those who eat 0 to 11 per cent of their calories in the morning gain nearly 3 pounds. More good news – go for a fatty breakfast. Studies are showing that a fat-filled morning meal will jumpstart your metabolism for the day faster than a low-fat, low-calorie breakfast. However, before you go to the shop to stock up on bacon (nothing wrong with a slice here and there), here’s a quick reminder to primarily go for healthy fats like avocado, eggs, nuts, and the likes. These have tons of additional beneficial components, and their fats are a slow burner, which means they keep you full and energized, avoiding the munchies.
