Many foods are considered key to a balanced diet, but Dr Michael Mosley stressed the importance of eating enough protein. The benefits of eating this “crucial” micronutrient are endless, with the nutritionist highlighting that consuming enough of it will aid weight loss.
He noted that the biggest driver of people’s appetites are protein sources, claiming it’s the lack of protein in a person’s diet that causes cravings.
“When I eat eggs or fish for breakfast, I stay full until lunchtime,” he said.
“But if I eat the same number of calories in the form of cereal or toast, I am craving a snack by mid-morning.”
Eggs, fish, meat and tofu are all rich in protein and can help build muscles, enzymes and much of the infrastructure of the body.
Eating enough of it is absolutely vital for growth and repair.
Currently, the Government guidelines for protein consumption is around 50g per day; a figure Dr Mosley labelled “way too low”.
“You need more protein after the age of 60 because your body is less able to absorb and utilise it,” he explained.
To back up his claims, he used an experiment by two leading Australian academics, Prof David Raubenheimer and Prof Steve Simpson, as an example.
During the study, the experts found that a lack of protein in people’s diets is a major driver of the current obesity epidemic if not consumed properly.
Dr Mosley pointed out that the 22 healthy volunteers used consumed 210 more calories per day when they were on a low-protein diet than they did on a high-protein diet.
“Do that on a regular basis and you would soon find yourself piling on the weight,” he wrote for Science Focus.
“The volunteers also reported feeling hungrier a couple of hours after eating the low-protein breakfast, despite eating the same number of calories as on higher protein days. That is certainly what I find.”
Prof Raubenheimer and Prof Simpson’s “protein leverage hypothesis” suggests that the main reason people are putting on weight is that “we are surrounded by ultra-processed foods that are typically rich in fats and carbs but low in protein”.
“If you don’t get enough protein in your diet, then you will develop cravings and overeat in a largely unconscious attempt to hit critical protein targets,” Dr Mosley added.
“They say that we need to consume around 15 to 20 percent of our daily calories in the form of protein.
“This amounts to around 100 grams of protein if you are eating the normal 2,000 to 2,500 calories a day.”
