Fat loss

Deficits, plateaus, maintenance and the parts of fat loss that a number on a scale will not tell you.

Fat loss is a calorie deficit held long enough to matter, and almost everything hard about it is the 'held long enough' part. These articles cover how big a deficit should be, why the scale moves in ways your body does not, what a plateau usually is, and how to stop losing without starting to gain.

What changes about fat loss after 40

Less than the marketing suggests and more than nothing. Muscle loss, recovery, sleep and medication all shift the picture; metabolism itself shifts least.

Breaking the restrict-and-binge cycle

Severe restriction reliably produces the eating it was meant to prevent. Why the cycle is physiological as well as psychological, and how to step out of it.

Terms used in this topic

  • BMR

    BMR, or basal metabolic rate, is the energy your body spends at complete rest to keep organs, temperature and basic cell function going; it is the floor of your daily expenditure, not a calorie target.

  • Body recomposition

    Body recomposition is losing fat and gaining muscle at the same time, which produces a visibly different body at a nearly unchanged bodyweight and is most achievable for beginners and people returning after a layoff.

  • Calorie deficit

    A calorie deficit is the amount by which your daily energy intake falls below your daily energy expenditure; sustained over weeks, it is the only mechanism by which stored body fat is lost.

  • Energy balance

    Energy balance is the difference between the calories you take in from food and drink and the calories your body spends over the same period; a negative balance means fat loss, a positive one means gain.

  • Maintenance calories

    Maintenance calories are the daily intake at which your weight holds steady over several weeks, measured from your own data rather than predicted by a formula.

  • NEAT

    NEAT, or non-exercise activity thermogenesis, is the energy you spend on everything that is not sleeping, eating or deliberate exercise: walking, standing, chores, fidgeting and carrying things.

  • Satiety

    Satiety is how full a food keeps you and for how long, which depends far more on its protein, fibre, water and volume than on its calorie count alone.

  • TDEE

    TDEE, or total daily energy expenditure, is the total number of calories your body spends in a day: resting metabolism, the energy cost of digesting food, deliberate exercise and all incidental movement combined.

  • Water weight

    Water weight is the short-term change in body mass caused by shifts in body water, glycogen, sodium and gut contents, which can move the scale by one to three kilograms without any change in body fat.

  • Weight trend

    A weight trend is a rolling average of your daily weigh-ins, usually over seven days, which strips out water and gut-content noise and shows the direction body fat is actually moving.
