Our genetics play a big role in how easy we find it to gain and lose weight. But it's possible to be a healthy weight despite your genes, an expert in the genetics of obesity said. Don't focus on calories aloneTo lose weight, you have to be in a calorie deficit , meaning you're burning more calories than you consume. Focus on your health over your appearancePeople want to lose weight for lots of reasons but a common motivation is to fit into societal beauty ideals. This can prove to be a weak motivator in the long run though, and doesn't necessarily benefit your health, Yeo said.
