Tactics that actually work
Small changes with real evidence behind them, ranked by how much they do for how little they ask of you. Every one carries its effect size and its honest caveat, including the ones that are oversold everywhere else. No metabolic magic, because there isn’t any.
Swap the sugary drinks
The single biggest win available to anyone who drinks their calories, and it costs almost nothing.
~250 calories a day per drink dropped
Sleep a bit longer, eat noticeably less
If you're under about six and a half hours, this is a bigger lever than most diets.
−270 calories a day, eaten without trying
Eat the bulky thing first
A soup or salad before the main course quietly takes 100+ calories off the meal.
7 to 20% less energy over the whole meal
Decide the swap before you're in the moment
Deciding once beats deciding nightly on willpower.
One of the most reliable behaviour-change techniques there is
Plate it, don't graze from the packet
The single most reliable environment change: portion out, then put the packet away.
150 to 230 calories a day across the day
Eat without a screen, remember the meal
Distracted eating shows up later as more snacking, not less.
Distracted eaters eat substantially more afterwards
A short walk after eating
Two to fifteen minutes flattens the glucose spike considerably.
17 to 24% lower glucose response
Steps are for your health, not your waistline
Walking is oversold for weight loss and undersold for everything else.
About 1.3kg from walking alone
Put the protein at the start of the day
Around 30g at breakfast reliably reduces evening snacking.
Less evening grazing, though the day may partly compensate
Weigh yourself as data, not a verdict
Daily weighing helps, provided the number isn't allowed to mean anything about you.
Consistently associated with greater loss and better maintenance
Wait out the craving instead of fighting it
Cravings peak in about five minutes. Suppressing them makes them worse.
Defusion beats suppression; suppression rebounds
Add something instead of banning something
Every rule you make is a rule you have to keep. Additions don't work like that.
Adding a behaviour has roughly double the effect of cutting one
