Struggling with losing weight over 50? You're not alone. Losing the beer gut and revealing your abs an increasingly difficult job. Most people try cardiovascular training, such as a HIIT workout, a Couch to 5K plan for running or even walking to lose weight – and while all of the above are great, they may not be address the real weight gain problem that occurs when we get older.
The biggest problem is metabolic slowdown. Our metabolism, the group of chemical reactions that keeps our bodies ticking over, burns calories even while at rest due to the simple effort of keeping our bodies going. In younger people, metabolism burns bright and fast, torching calories quickly. But as we age, our metabolism often slows down.
One of the causes of this is a process called muscular atrophy, in which the body's stores of muscle waste away as we age, which is why elderly people are physically very weak. Our body expends energy supplying muscle with oxygen via red blood cells, so as our muscle wastes away, so too does our metabolism, as it's spending less energy. It's not the only factor in metabolic decline, but it's certainly a contributing one.
The solution? Training to build muscle as well as burn calories will defy aging and help you keep the weight off. The UK's National Health Service reports "muscle cells require more energy to maintain than fat cells, so people with more muscle than fat tend to have a faster metabolism".
A study from Quincy College in Boston backs this up, looked at people between the ages of 21 and 80, all beginning exercisers, and had them lift weights between twice and three times a week for 10 weeks.
At the end of the programme, the students had lost an average of 3.9lbs of fat and put on 3.1lbs of muscle. This improved their body's ratio of fat-to-muscle, making them fitter and stronger instead of just thinner. It proves resistance training is a great way for over 50s to lose weight by revving up your metabolism, and by adding cardio into the mix as well, you'll continue to burn additional calories.
You don't have to start living big heavy weights in the gym to see results – this can be accomplished at home with a set of the best adjustable dumbbells or best resistance bands. Resistance bands especially are exceptional for older exercisers, as they are very light, can travel anywhere and are very safe to use, with none of the jerky movements that can come with lifting weights.
Pull-ups and dips, push ups, squats and other bodyweight exercises can help you build muscle even without any equipment, making these simple muscle-building moves a great way to get started. These moves often require a degree of core strength, and moves like squats and push ups can help you build strength to take on weighted versions like the barbell squat and bench press.
You can also keep your metabolism active by eating more protein. As opposed to carbohydrates, which are easy for the body to break down and store as fat, protein sources have a high "thermic effect", which means it's much more difficult for your body to break down into usable stuff.
You're using more calories just during the digestion phase to break down your steak, chicken or oats: plus, you need lots of protein to build up all that muscle. In addition, one study published by researchers from Yale University School of Medicine, among others, found high-protein diets "have considerable beneficial effects on satiety and weight control".
In short, a high-protein diet makes you feel fuller for longer when compared to a high-carbohydrate diet, helping you to control hunger pangs while fuelling your muscles and increasing your metabolism. The key is to reduce carbohydrates high in starch and sugar, such as chips, fries, soda, wine, beer, bread, white rice and so on. You can partially replace them with low-GI alternatives such as whole grains, fruit and vegetables, and up your protein intake too, using sources such as lean meat, fish, pulses and even our best protein powder for weight loss. Combined with regular resistance training and the occasional cardiovascular workout, you'll soon begin to see results.
