It is very easy to make different food choices when at home. You might be snacking more because you are not going anywhere. Perhaps you have changed your eating habits out of boredom or stress.
Children may be fixed on certain foods and are happy to eat the same things every day. Or you may not have time with a lot of people at home.
Just as making small changes to your routine can keep you active, so making simple swaps to your food choices can be effective in eating more healthily. Better still, by being active you are using up calories as well.
