Yes, Men Lose Weight Easier Than Women!

“It's not fair,” my friend cried. “I’m the one on a diet, and he’s the one who loses weight!”. Both my friend and her husband had put on some weight since they have been working from home. Two weeks later, my friend’s weight hadn’t budged, while her husband had lost six pounds without even trying.

If you are a woman and have ever tried to lose weight, you may have observed this phenomenon yourself – and you are not imagining it.

Ireland now has the second highest obesity rate in Europe according to a recent survey by Eurostat, the EU’s statistics agency. And according to Healthy Ireland research, 6 in 10 Irish people are overweight or obese, with men being more likely to be more overweight than women (men: 43%, women: 31%). However, the proportions that are obese are more closely aligned (men: 25%, women: 22%).

Although the obesity epidemic affects both sexes, men and women gain, carry and lose weight very differently.

The role of body composition

Thanks to differences in body composition, women are at a disadvantage right out of the gate because they naturally carry more fat than men.

Men have more muscle mass, and muscle is metabolically “expensive” to keep. That means it uses up energy – and that’s calories to you and me - even when at rest while fat does not.

Muscles burn considerably more calories than fat, making the male metabolism 3-10% faster than the female one. No surprise then that in studies, men are consistently found to do better on the exact same diet a woman might follow.

Moreover, nature has distributed body fat in different ways. In women, it mainly sits on the hips and bum, where it serves as a vital store, for example for pregnancy. In men, fat tends to accumulate around the belly.

During menopause, women lose even more muscle and some bone mass, which increases their body fat percentage. On top of that, a redistribution takes place. The padding on hips and bum reduces, while belly fat increases. The female figure changes from “pear” to “apple” because male hormones such as testosterone, which are present in the female body also, become more dominant post-menopause.

If you are overweight, you are better off carrying your weight around the thighs and bum rather than the belly. Abdominal fat is a lot more metabolically active and produces not only hormones – which, among other things, further affect weight, weight distribution and hunger – but also inflammatory compounds. This visceral belly fat is unhealthier as it promotes inflammation, increasing the risk for heart attack and stroke, but we know from studies that it is lost more quickly than fat from the hips.

This puts overweight men at risk sooner than overweight women. Yet ironically, while doctors tend to advise overweight women to lose weight as soon as their BMI passes the ‘healthy’ 25 mark, they rarely ask men to lose weight until their blood pressure and cholesterol readings are already off the scale.

And what about calories?

Women are repeatedly told by 'diet culture' that all they need to do is reduce their calorie intake.

The problem with this is that low-calorie crash diets can lead to rapid weight loss at first, but the body reacts to this “famine” by downregulating energy expenditure. As a result, the rapid weight loss soon slows down and may even grind to a halt, even though the dieter eats less and less.

The minimum number of calories we need at rest is called “basal metabolic rate” (BMR). It is already higher for men due to their greater muscle mass.

By following crash diet after crash diet, many women gradually decrease their BMR further and further, not losing - and possibly even gaining weight - while eating fewer and fewer calories.

If a man goes on a diet at all, it is often much later in life. Their BMR is intact, and they have that extra muscle, making it relatively easy for them to lose weight and are less affected by this calorie dilemma.

So, if I just exercise I'll lose weight?

For men, exercise is central to weight loss. Men often succeed by motivating themselves with challenges, such as a marathon, a triathlon or the three peaks. Also, they don’t mind lifting weights at the gym.

Women, on the other hand, tend to worry about accumulating too much bulk, going for endurance exercise instead. While that’s great for stamina, heart health and mood, it doesn’t do much for weight loss.

Building muscle really is key here, and if you want to lose weight and increase your BMR, resistance exercise is crucial.

And there’s more injustice… According to a 2009 study, the “hunger hormone” ghrelin spikes after a workout in women, while leptin, which tells the brain that you’re full, plummets.

Not so in men. So post-workout, women tend to eat more, which puts them at risk of gaining weight – the exact opposite of what most women are trying to achieve!

Men don’t experience this same hormonal fluctuation. Researchers are not sure why that is. They can only speculate, and one theory is that it’s the female body’s way to avoid energy deficits to preserve fertility and perpetuate the species. In the female body, a lack of calories suppresses ovulation and hormones that make reproduction possible.

And there's more...

But physiology is not all. There are also mental elements that vary between men and women. Of course, there are some generalisations here, and there are always exceptions to the rule, but these are the findings of research papers looking into eating behaviours.

Men are more likely to overeat than women. They are less likely to cook, whether that’s due to time constraints or a lack of skill or interest. Unless home-cooked meals are provided for them, many men reach for junk foods. They are not just convenient but also highly palatable and easy to overeat – in fact, they are designed for us to overconsume them!

Women who eat too much tend to go for those foods as well, but for different reasons. In stressful situations, they reach for food that will activate the reward centre in the brain particularly well and fast. That means foods that contain a lot of fat and sugar.

In the short term, such foods provide satisfaction, but in the long run, they increase the risk of developing diabetes, heart disease and dementia. It’s a kind of self-medication of the brain in an attempt to briefly dampen the constant firing of stress hormones.

Again, hormonal fluctuations play a significant role. You might beat yourself up about lacking willpower but body chemistry is near impossible to beat. It always wins!

How to be successful at weight loss

Successful weight loss programmes therefore need to be adapted for Men and Women.

For men, oftentimes a simple plan and roadmap is all they need to get started.

For women, they already know what a healthy diet should look like and don’t mind cooking. However, they need more support to combat emotional eating and manage stress.

Providing the right dietary approach, exercise programmes, stress management, meal preparation and emotional support (if needed) all play a part in weight loss and look different for both sexes.

All my plans and programmes are designed to be easy, enjoyable and flexible enough to work with your busy lifestyle.

So, don’t measure your weight loss against your partner because as we now know, Men and Women are not the same when it comes to weight loss.
