Testosterone is said to be one of the secrets for men who are naturally slim.
The hormone – a hydrophobic molecule – likes to adhere to fat, which means that less fat lingers around the middle.
It also helps to build muscle, fuel metabolism, and maintain insulin sensitivity (which prevents diabetes).
Lower testosterone levels make it easier for the body to store fat. Similarly, obesity hinders testosterone production.
As men get older, testosterone levels decrease naturally, at a rate of about 1 percent per year after the age of 30.
This means that belly fat crawls in.
The female body has a delicate balance between progesterone and estrogen.
Higher levels of estrogen contribute to the formation of fatty tissue. In younger women this is compensated by strong levels of progesterone.
From the age of 35 the levels of both hormones decrease, leading to menopause.
The progesterone level, however, decreases faster – so that fatty tissue is formed with an apparently less controllable speed than before.
The loss of muscle mass is one of the biggest factors that lead to a slow metabolism.
Muscle tissue is the largest consumer of glucose in the entire body.
If you can't maintain your lean muscle mass as you age, there is less to consume that glucose.
In turn, that glucose can be converted into sustained body fat.
As a result, your body does not process carbohydrates as quickly as before.
HOW TO BAT IT
TRAIN LIKE A MILLENNIAL
Experts say it is important that elderly people do resistance training rather than pure cardiovascular training.
Hoewel Although aerobic workouts are good for heart health, muscle building is just as important to protect yourself against developing inflammation and diabetes.
Resistance training is a collective term for any exercise that causes muscles to work against a certain form of resistance – both weights and your own body weight.
Some exercises include planking, squats and bicep curls.
EAT MORE PROTEIN
Protein shakes are sold to 20-person gym enthusiasts who want to strengthen their muscles.
But the nutrient is essential for older people to build muscle and keep metabolism stable.
Protein is essential because it fills your body with the amino acids to repair and replenish damage – and you also need it if you want to build muscle.
