It only takes a quick scan across a few health and fitness websites and blogs to figure out that people are basically obsessed with the notion of finding the best pre-workout foods. From protein to carbohydrates, there are a number of theories out there – and it all depends on what you are looking to achieve.
When it comes to keeping weight off, one recent study proved that exercising on an empty stomach (“fasted training”) can be highly effective in helping you to lose weight. If you are looking to shed some pounds but exercising while hungry doesn’t appeal to you, you’ll be pleased to know that certain foods have a proven ability to assist in fat burning.
According to a study published in The Journal of Nutrition, eating low-glycemic (GI) foods like grapefruit before a workout can be highly effective in assisting in fat loss. Low GI foods are those that prevent blood sugar from spiking and release energy slowly – and are generally thought to be the best type of carbohydrate for your body.
The study found that participants who ate a low GI breakfast three hours before a workout burned up to 55 percent more fat than those who ate a high GI breakfast (foods such as white bread and white rice). After a low GI breakfast, the chance of weight loss was further increased as participants reported feeling fuller for longer – decreasing their risk of unnecessary snacking and overeating during their next meal.
While foods such as milk, porridge and grainy bread are also low GI, grapefruit is generally recommended as being one of the best fat burning pre-workout foods because it also assists with hydration (it is 90 percent water) and contains a very low amount of calories. With half a grapefruit also containing 80 percent of your daily vitamin C intake, eating grapefruit for breakfast also benefits your immune system and supports your body’s natural detoxification processes.
Eating a high protein food such as eggs or Greek yogurt alongside half a grapefruit in the morning will also help to support muscle repair and growth.
