Losing weight isn't easy, but it is simple. You have to commit to a regular pattern of healthy choices – getting enough sleep, doing enough exercise, and eating generally healthy – on a consistent basis. Over time, sometimes slowly, sometimes quickly, the results will speak for themselves.
There's quite a few ways to go about this in terms of exercise: some people like to do the best exercises for weight loss, stuffing their HIIT workouts with burpees and broad jumps. Others want to jump on the best exercise bike and do steady-state cardio, or go for a run. However, when it comes to diets, there's a simple rule to follow: in order to lose weight, you've got to eat less calories.
So how many calories do you need to cut? Researchers from the American Heart Association (opens in new tab) found older, obese patients that exercised and cut just 250 calories a day – just over a pint of beer, for reference – found big improvements in vascular health, reducing the risk of blood clots and heart disease. Cutting even a small amount of calories in conjunction with regular exercise can be beneficial.
However, if you're looking for weight loss, you might need to go bigger. The golden rule for losing weight is to eat less calories than you burn. So, the answer to "how many calories do I need to cut?" is "as many as you need to, depending on the amount of exercise you're doing".
That could mean cutting a small amount of calories and doing more exercise. On the other hand, it could mean doing less exercise and cutting a larger amount of calories. However, we wouldn't recommend taking in too few calories to function properly – there's nothing wrong with three square, healthy meals a day and some low-calorie, beneficial snacks like a piece of fruit.
Instead, swap to healthier, lower-calorie alternatives. 100 grams of broccoli on the side of your steak, for example, contains less calories than 100 grams of fries. Instead of frying or roasting your food, dousing it in lots of vegetable oil full of extra calories and saturated fats, cook it in an air fryer, which circulates a fraction of the amount of oil around the contents with hot air currents.
