Exercise for weight loss: how much do you actually need?
Why exercise alone rarely moves the scale much, and what it's actually the best tool in existence for.

The uncomfortable truth about exercise and the scale
A 30-minute brisk walk burns roughly what a small bottle of soft drink contains in calories. Exercise alone, without any change to eating, moves the scale far less than most people expect, and appetite often quietly rises to compensate. This is not a reason to skip it; it's a reason to be honest about what it's for.
What exercise is genuinely the best tool for
Keeping weight off once it's lost, protecting muscle while you lose fat (so the weight that comes off is fat, not muscle), and lowering blood pressure, blood sugar and cardiovascular risk largely independent of what happens to your weight at all. People who exercise regularly keep weight off far better than people who rely on diet changes alone.
How much is actually enough
Roughly 150 minutes a week of brisk walking or similar activity, about 20-25 minutes most days, is the widely-used benchmark for general health. For weight maintenance specifically, some evidence points toward needing closer to 250-300 minutes a week. Either way, consistency across months matters far more than intensity on any single day.
It doesn't need a gym
Brisk walking, stairs instead of a lift, dancing, carrying shopping, an okada-free commute twice a week, all count. The best form of exercise is the one you'll actually keep doing in six months; a modest routine you sustain beats an ambitious one you abandon after a fortnight.
