If you're over 40 and you started gaining weight around your middle, despite feeling like you're doing all the right things, cutting your calories may actually be the wrong place to start. There's one nutrient I look at very closely with almost every woman I work with, because getting enough of it can affect your hunger, your muscle, your energy and your body composition at the same time. And most women I speak to simply aren't getting enough of it, particularly at the time of day when it could make the biggest difference.

(0:27 - 0:56)
By the end of this video I'll show you exactly what that nutrient is, how much you need, how to spread it across your day and why one of the rules around it you've probably heard is actually a myth. And stay with me because later I'm going to show you a fascinating study where women changed just one simple thing in their diets and ended up with significantly better body composition without going on a calorie-restricted diet or an exercise programme. Let's start with why metabolism becomes such a big issue during perimenopause.

(0:56 - 1:06)
So many women tell me, Angela, I haven't changed anything but I'm gaining weight. And they're often right. It isn't necessarily because they're suddenly eating dramatically more.

(1:07 - 1:33)
Their biology is changing. As oestrogen begins to fluctuate and then decline, we can see changes in insulin sensitivity, inflammation, oxidative stress, cortisol, sleep, appetite regulation and lean muscle mass, all of which can impact your body composition. Many women also become less physically active, not because they've suddenly become lazy, but because they're tired, they're sleeping less well and they have a lot more going on.

(1:34 - 1:44)
I know that as my kids have grown up, I spend more time driving them to places than doing active things like I did when they were younger. So you can end up with this perfect storm in midlife. You're losing muscle.

(1:45 - 1:54)
You may be feeling hungrier. Your blood sugar regulation is not quite as efficient. You're moving less without even realising it and your body composition starts to change.

(1:55 - 2:14)
That's why the strategies that worked beautifully for you in your twenties and thirties may stop producing the same results in your forties and fifties. And this is where the nutrient I mentioned becomes much more interesting than simply something bodybuilders eat to grow muscle. So if you haven't guessed it already, it's protein.

(2:14 - 2:28)
One of the most interesting reasons protein matters has nothing to do with building muscle. It may help explain why you can finish a meal and still feel as though you want to eat something else. There's a scientific theory called the protein leverage hypothesis.

(2:28 - 2:54)
And the idea is relatively simple. Your body has a strong biological drive to obtain enough protein because the amino acids in protein are required to build and repair tissue, to produce enzymes, neurotransmitters, and many of the structures your body needs to function. If your diet is relatively low in protein, one theory is that your appetite may continue driving you to eat in an attempt to reach that protein requirement.

(2:54 - 3:10)
But most of us don't get a craving for another chicken breast. We reach for something convenient and rewarding, crisps, biscuits, or chocolate. So you can end up consuming more energy but still not giving your body very much additional protein, which is what it was looking for.

(3:10 - 3:19)
And that's why increasing protein can help reduce cravings. It isn't simply about having more willpower or discipline. It's about setting yourself up for success.

(3:19 - 3:35)
Your cravings drop when you finally give your body more of what it was actually asking for. There are lots of other reasons protein matters, but for body composition, there are three I particularly want to talk about. First, alongside resistance training, it helps you preserve and build lean muscle.

(3:35 - 3:57)
And maintaining muscle becomes increasingly important as we age because it supports our strength, mobility, metabolic health, and our ability to remain physically capable later in life. Second, protein is incredibly satiating. It helps you feel fuller for longer, which can make it much easier to regulate your calorie intake without spending the whole day thinking about food.

(3:57 - 4:15)
And third, protein has the highest thermic effect of the three macronutrients, protein, carbs, and fats. In other words, your body uses energy to digest and process the food you eat. And protein requires considerably more energy to process than carbohydrate or fat.

(4:15 - 4:38)
In fact, around 20% to 30% of the calories from protein are used in digestion and processing compared with approximately 5% to 15% for carbohydrates and around 2% to 4% for fat. So when I call protein a metabolic reset food, I'm not suggesting it's magic. I mean that it addresses several of the problems women experience during midlife at exactly the same time.

(4:38 - 4:56)
Hunger, loss of lean muscle, and body fat changes. But simply knowing that protein matters isn't going to be enough because this is where I see a lot of women getting it wrong. I generally recommend somewhere around 0.8 to 1 gramme of protein per pound of your target body weight per day.

(4:56 - 5:06)
And if that sounds like dramatically more than you're eating now, don't panic. You don't need to suddenly double your protein tomorrow. Start by working out roughly where you are today and then build up gradually.

(5:07 - 5:28)
Gradual consistency always trumps short bursts of intensity. And there's another mistake I see all the time, and that's being so busy in the morning that you either skip breakfast or grab a quick piece of toast or a pastry on the go. Maybe a small salad for lunch and then you try to squeeze in almost your entire daily required protein intake into one dinner.

(5:28 - 5:44)
I'm not saying that you have to eat protein all day. Total protein intake across the day is the most important thing. But practically, it becomes very difficult to get enough protein if you've barely eaten any before 6 p.m. So I find it much easier to structure protein across several meals.

(5:44 - 6:20)
A useful target for many women is around 30 to 40 grammes at each of breakfast, lunch and dinner, roughly three to four hours apart, adjusting that depending on your total daily requirement. And as we get older, aiming towards the higher end of that range may become particularly useful because our muscles can be less responsive to the anabolic stimulus from protein, something known as anabolic resistance. Some research also suggests that distributing protein more evenly across the day may be beneficial for lean mass and strength compared with eating very little protein earlier in the day and trying to make up for it all at dinner.

(6:21 - 6:42)
One of the biggest changes I ask women to make is to stop thinking of breakfast as predominantly toast, cereal, pastries or even just a coffee on the run. Try starting the day with a meaningful serving of protein. For many women, aiming for somewhere around 30 to 40 grammes works really well and that can have an immediate effect on satiety, but also concentration.

(6:42 - 6:56)
The women I work with often tell me how much more switched on they feel once they start eating a healthy dose of protein at breakfast. You'll also find you're not hunting for something sweet at 11 o'clock. And there's another practical reason I like putting protein at breakfast.

(6:56 - 7:22)
Breakfast is often the lowest protein meal of the day, so increasing it here is one of the easiest ways to distribute your intake more evenly rather than trying to catch up at dinner. For years, the gold standard for muscle performance has been protein and creatine, but there's a piece most high-performing women are still missing and it sits deeper than anything in your current stack. Every workout, every long day, every demand on your body runs on cellular energy.

(7:23 - 7:41)
At the centre of that system are your mitochondria and from your mid-30s onwards, accelerated by the hormonal shifts of perimenopause and postmenopause, mitochondrial function naturally declines. Energy production becomes less efficient. Strength, recovery and resilience starts to compound in the wrong direction.

(7:42 - 8:04)
Mitopure by Timeline contains urolithin A, which supports mitophagy, your cells' process for clearing out damaged mitochondria and restoring more efficient energy production. 18 years of research and 25 human clinical trials back this. One study showed a 12% improvement in muscle strength in four months with no change in exercise.

(8:04 - 8:17)
Performance starts at the cellular level. When your mitochondria are working efficiently, everything above that, your training, your focus, your recovery operates at a higher level. I've been taking mitopure every day for over a year.

(8:17 - 8:29)
I've seen real improvements in my strength in the gym, my power output on the bike and my energy throughout the day. But the moment that convinced me the most was when I stopped it for six weeks. My energy dropped noticeably.

(8:29 - 8:50)
That told me more than any improvement stat could.

(8:51 - 9:15)
Our eating patterns also provide timing information to our body and those rhythms can become more disrupted during the menopause transition. So creating a consistent morning eating pattern, particularly one built around high quality nutrition, including protein, is another useful way of reinforcing those daily rhythms. Whenever I talk about having 30 or 40 grammes of protein at a meal, somebody always asks me the same question.

(9:16 - 9:28)
Can your body absorb more than 30 grammes of protein at once? The answer is yes. This is perhaps one of the biggest myths around protein. Your body doesn't suddenly get a 30 grammes or 40 grammes and then throw everything else away.

(9:29 - 9:46)
You digest and absorb protein above that amount. The more useful question is how much protein at a particular meal is required to generate a strong muscle protein synthesis response. For many people, that's somewhere around 30 to 40 grammes of high quality protein that gives a very good stimulus.

(9:47 - 10:04)
But if you eat a large chicken breast and you're getting 50 or 60 grammes, that additional protein isn't wasted. Those amino acids can still be used elsewhere in the body to support things like tissue repair, enzymes, hormones, immune function, and neurotransmitters. So don't be frightened of having more than 30 grammes in one sitting.

(10:04 - 10:19)
The reason that I really like distributing protein throughout the day is because it just makes it easier to hit your daily target. It supports satiety and it gives your muscles repeated opportunities to respond to protein. And this is where I think we sometimes make nutrition more complicated than it needs to be.

(10:20 - 10:39)
Start with whole food protein sources wherever possible. Things like fish, chicken, turkey, lean meat, eggs, Greek yoghurt, cottage cheese, and other high protein dairy if you tolerate dairy products. If you eat a predominantly plant-based diet, things like tofu, tempeh, edamame, beans, lentils, and chickpeas can all contribute.

(10:39 - 10:59)
You just need to be a little bit more intentional because plant proteins generally contain lower amounts of some of the essential amino acids, including leucine. So combining different plant protein sources across the day can really help. And if you're struggling to reach your overall target, a high quality protein isolate to top up can be a practical option as well.

(11:00 - 11:12)
And the same goes if you're eating animal protein. If food alone makes your target difficult, you can use a good quality protein powder to top up on occasions. I personally use protein shakes myself when I'm travelling or when I need something convenient after training.

(11:13 - 11:30)
Whole food always comes first, but protein powder is useful when it makes your life easier or you're in a rush. When we look at fat loss, protein gets even more interesting. There was a fascinating 12-week randomised controlled trial involving 47 women between the ages of 30 and 60.

(11:31 - 11:46)
The women had what researchers call normal weight obesity. That means their BMI was in the normal range, but they had a relatively high level of body fat above 30% and correspondingly lower levels of lean mass. The researchers split them into two groups.

(11:46 - 12:04)
One group ate a standard protein diet of around 1.1 grammes per kilogramme of body weight per day. The other group increased their protein intake to approximately 1.8 grammes per kilogramme of body weight, which is roughly 0.8 grammes per pound. And here's the part that makes the study so interesting.

(12:04 - 12:14)
The diets were designed around maintenance calories. The researchers weren't deliberately putting the women into a calorie deficit. There was also no exercise programme.

(12:14 - 12:33)
In fact, the participants were specifically asked not to change their lifestyle during the 12 weeks and one woman was actually removed from the study because she started exercising. So what happened? After 12 weeks, the women eating the higher protein diet had moved in exactly the direction most women want. They had lost body fat while gaining lean mass.

(12:33 - 12:55)
The standard protein group moved slightly in the opposite direction, losing some lean mass and gaining a small amount of body fat. Now, there are a couple of caveats because I always want to give you the full picture when I'm talking about research. Although the diets were designed to maintain calorie intake, the higher protein group ended up eating around 6% fewer calories over the course of the study.

(12:55 - 13:18)
That reduction wasn't statistically significant, so we can't say that increasing protein directly caused every bit of the fat loss. But I think this makes the result more interesting because it may reflect one of the effects we talked about earlier, which is when you increase protein, you often feel fuller and if you feel fuller, you may naturally eat slightly less without consciously trying to restrict your calories. There was another limitation.

(13:19 - 13:37)
Body composition was measured using bioelectrical impedance rather than a more precise method such as a DEXA scan. So I'd be a bit cautious about taking the exact change in lean mass to literary. Changes in body water can influence those measurements and the review itself points that out as a limitation.

(13:37 - 14:00)
But the overall result is still fascinating. The women who increased their protein had significantly better body composition outcomes without being deliberately placed on a calorie restricted diet or asked to start an exercise programme. And that's why when women come to see me and say, I need to lose weight, how much do I need to cut calories? I don't necessarily start there.

(14:00 - 14:26)
Sometimes the better first question is, are you eating enough of the right things, particularly protein? If you've watched this and realise your protein intake is probably quite low, don't try to overhaul your entire diet. Start with three things. First, work out roughly how much protein you're eating a day and compare that with your target of 0.8 to 1 gramme of protein per pound of target body weight.

(14:26 - 14:41)
Second, look at breakfast. Could you get somewhere around 30 to 40 grammes of protein into that first meal instead of starting the day predominantly with carbohydrates? And third, make protein the anchor of your other main meals. You don't need perfection.

(14:41 - 14:55)
You need consistency. And once that becomes automatic, then you can look at the rest of your nutrition, your resistance training, your sleep, your recovery, and everything else that contributes to your body composition. Because protein is not a substitute for resistance training.

(14:55 - 15:06)
Resistance training provides the signal telling your body to build muscle. Protein provides the building blocks to support that adaptation. And as we get older, in particular, we want both.

(15:06 - 15:15)
If there's one thing I'd like you to take away from this video, it's this. Protein isn't simply about building muscle. I think of it as helping to build biological capacity.

(15:15 - 15:32)
Every cell in your body relies on amino acids. They're involved in producing enzymes, hormones, neurotransmitters, immune cells, and connective tissue. Protein supports your metabolism, your energy, your brain, your recovery, your bone health, and your ability to maintain lean muscle strength and independence as you age.

(15:33 - 16:05)
So before you cut calories, before you cut carbohydrates, and before you start another restrictive diet, ask yourself one simple question. Am I eating enough protein? Because in my experience, when women get their protein intake right, everything else becomes easier. They feel fuller, their cravings reduce, they have more energy and mental focus, they recover better from exercise, they're better able to support and maintain lean muscle, and they're creating a much stronger foundation for improving body composition without feeling as though they have to spend the rest of their lives dieting.

(16:05 - 16:25)
Optimising my protein intake is also just one of the habits that has helped me reduce my biological age by 25 years during perimenopause. If you'd like to discover the other nine, I've put them together in my free guide, 10 Habits That Helped Me Reduce My Biological Age by 25 Years.

If you're over 40 and gaining weight around your middle despite doing everything right, cutting calories may be the wrong place to start. In this episode I break down why protein - not restriction - is the first thing I look at with almost every woman I work with.

We cover what's actually happening to your metabolism in perimenopause, why low protein can quietly drive your cravings, how much you really need, why breakfast is the meal most women get wrong, and the 30g "absorption limit" myth you've probably been told for years.

I also walk through a 12-week trial in women aged 30–60 where the higher-protein group improved their body composition - with no calorie deficit and no exercise programme - and I give you the caveats too. Protein isn't just about building muscle. It's about building biological capacity.
