Weight and metabolism
Resetting your metabolic set point
Your metabolism has its own set point, shaped by your age, genetics, activity level, temperature, and the amount of calories you eat. It is not set in stone. This guide explains why hard caloric restriction stalls, and how to keep losing weight without burning out your metabolism.
The metabolic set point
Your metabolism has its own set point, determined by many things: your age, your genetics, your activity level, your temperature, and the amount of calories being consumed. This set point is not set in stone. It can change.
Often weight loss involves caloric restriction, which seems like a simple calculation: eat fewer calories than you use, so you burn your own fat to make up the difference. Well, yes and no. Caloric restriction such as intermittent fasting can put you in a deficit, but if it is not done properly, the weight loss will not be sustained for very long.
What happens with continued caloric restriction
Initially, during caloric restriction, your metabolism keeps burning at its normal set point even though you are not eating enough calories to sustain it. This triggers you to lose weight. But once your body gets used to the new baseline of calories coming in, your set point drops, and so does the weight loss. Then you often begin eating even less to keep losing. It can continue until you are literally eating like a rabbit and still cannot lose any more weight.
Worse, your body often starts consuming its own muscle mass in a bid to draw more energy. Muscle mass goes down and fat mass goes up, even if you are training a lot at the gym.
How to keep your set point burning while you lose
So it begs the question: how do I keep my metabolic set point burning but keep losing weight? One method is to cycle your caloric restriction. Four weeks on, then two weeks off: four weeks on a lower-calorie diet, then two weeks increasing your calories back to your normal basal metabolic rate.
If you eat more food, your body temperature rises and your metabolism speeds up to increase energy expenditure. This helps keep your metabolic rate firing at its normal rate. Done well, you will find your appetite increases and you feel hunger as soon as you wake in the morning. That is usually a good sign your metabolic set point has corrected, and then you are ready to reduce calories again, but only for four weeks.
Vegetables are your kindling
Another good way to get your metabolism roaring is to eat lots and lots of vegetables. Vegetables are like kindling on a fireplace: they burn fast, bright, and hot, but not for very long. So you need to eat plenty throughout the whole day to keep your fire burning.
Fat is the slow log
Dietary fat is like a big thick log that struggles to catch alight, and it dims the existing fire. A lower-fat, high-vegetable diet is the best strategy while you are actively losing weight.

Frequently asked questions
Why does weight loss stall on a low-calorie diet?
Metabolism has its own set point, influenced by age, genetics, activity, body temperature and calorie intake. With continued hard calorie restriction the set point can drop, so the body burns less and weight loss plateaus. The approach here is to cycle calories rather than restrict relentlessly, so the metabolism keeps firing while you lose weight, instead of slowing to match a constantly low intake.
What is calorie cycling for resetting metabolism?
Calorie cycling here uses a 4 plus 2 pattern: around four weeks in a lower-calorie phase, then two weeks back at your basal rate, repeated. The lower-calorie phase pairs plenty of vegetables, aiming for around 10 cups a day, with lean protein and lower fat, while avoiding starchy vegetables, grains, higher-sugar fruit and added sugars. Returning to maintenance for two weeks is intended to keep the metabolic set point from dropping.
What can you eat during the low-calorie phase?
The low-calorie phase centres on vegetables, described as kindling that burns fast and bright, with a target of around 10 cups a day from greens, crucifers and everyday vegetables. These are paired with palm-sized servings of lean protein such as chicken, eggs, fish or lean beef, and small amounts of seeds or activated nuts. Foods to avoid include starchy and root vegetables, fatty meats, all grains, higher-sugar fruit and all sugars and sweeteners.
