Katrin,
The phrase you used stopped me. "I push through but I know I am running on less than I should be." That is not just an honest answer. That is a woman who has been carrying a load that is heavier than it looks, for longer than she probably realises, and doing it so well that most people around her would never know.
Wired but tired. Drained by early afternoon. Bloating that has been getting worse. Hair changes. Belly fat that was not there before. Knowing why your energy shifts and not being able to do much about it anyway. None of this is in your head, and none of it is a willpower problem.
What I see here is a body that has been under sustained pressure, and is now communicating that very clearly through a set of symptoms that are easy to dismiss individually but tell a very coherent story when you look at them together. The good news is that this story has an explanation. And an explanation means there is a real path through it.
Let me show you what I see.
You are already showing up three times a week. That part is working. What needs to change is what happens during those sessions. Comfortable training during perimenopause does not produce change. Your muscles need a reason to grow, and that reason is progressive challenge. The last few reps of each set should require real effort. If they do not, the weight is too light.
This does not mean training harder in a way that leaves you wrecked. It means being deliberate about pushing the weight up over time, tracking what you lifted last session, and giving your body something to adapt to. That is the shift that produces the toned, stronger feeling you are describing, and it does not require more time, just more intention within the time you already have.
Iron deficiency is one of the most underestimated drivers of the exact symptoms you are describing. The afternoon drain, the wired-but-tired feeling, the difficulty recovering from exercise, the hair changes. All of it can be directly caused or significantly worsened by low iron. And iron deficiency in perimenopause is extremely common because oestrogen decline affects absorption at the same time that hormonal changes increase demand.
If you are supplementing, make sure it is a well-absorbed form taken away from coffee and tea, which block absorption. If you have not had a full iron panel recently, including ferritin not just haemoglobin, that is worth doing. Ferritin can be critically low while standard tests come back normal. Getting this right is likely to change how you feel more than almost anything else on this list.
You do not need a perfect week. You need a floor. A minimum viable version of your routine that you can execute even when you are travelling, stressed, or socially overcommitted. One training session instead of three. Breakfast and dinner with protein even if lunch is a write-off. A walk instead of a gym session. These are not failures. They are the thing that keeps the habit alive so that coming back after a hard week does not feel like starting from scratch.
The pattern you described, where stress or travel tips the whole thing over, happens because the current plan is binary. Either you do it properly or you do not do it at all. A minimum viable floor changes that. It gives you a third option that is not giving up.
Perimenopause changes how your body responds to training. Heavy compound lifts, hip thrusts, deadlifts, rows, squats, are the most effective tools for preserving and building muscle during hormonal transition. They also support bone density and metabolic rate in a way that cardio and lighter Pilates work cannot replicate. This is the right time to be lifting heavier, not lighter.
Recovery matters more now than it did five years ago. Training hard on poor sleep or at the end of an already depleted week will add to the cortisol load rather than help it. If you are having a genuinely draining week, a walk and one moderate session is a better choice than pushing for intensity you do not have the reserves to support.
When you travel, find one gym session and keep the rest as walking. Hotels nearly always have something usable. One session in a travel week is a complete success, not a compromise.
You are already eating 2 to 3 protein servings a day, which is a solid start. The goal is to make sure those servings are spread across every meal rather than concentrated later in the day, and that you are pairing iron-rich foods with vitamin C to improve absorption. Red meat, dark leafy greens, lentils, eggs, and beans are your best iron sources. Eat them with something acidic, a squeeze of lemon, some tomatoes, a small glass of orange juice, and avoid tea or coffee within an hour of eating them.
Getting your iron up is not just about supplementation. It is about building a daily eating pattern that consistently delivers absorbable iron. Given that this is almost certainly driving a significant part of how you feel right now, this anchor is doing double duty.
You mentioned trying to eat fewer carbs. During perimenopause, going too low on carbohydrates can actually worsen cortisol dysregulation and disrupt thyroid function, which are already under pressure. Complex carbohydrates, oats, sweet potato, rice, sourdough, legumes, are what your body uses to produce serotonin and regulate blood sugar. Cutting them too aggressively can deepen the wired-but-tired cycle rather than help it.
The goal is not low carb. It is quality carbs paired with protein and fat at every meal. That combination keeps blood sugar stable, supports your hormones, and feeds the gut bacteria that are likely contributing to the bloating when they are not being looked after.
When life gets hectic, eating tends to either unravel into convenience food or drop off entirely as appetite suppression kicks in. Both responses make the cortisol and energy picture worse. Your body needs consistent fuel to manage stress, and when it does not get it, it responds by holding onto fat, particularly around the abdomen, and borrowing energy from wherever it can, which is usually your hair, your recovery, and your resilience.
On hard weeks, the nutritional goal is simple: three meals with protein, something green once a day, and enough total food that you are not running on empty. That is all. Save the optimisation for the weeks when you have the bandwidth for it.
You asked to stop without gaining weight, so here is the honest answer. Nicotine suppresses appetite and slightly elevates metabolism. When you stop, both of those effects reverse, which is why weight gain feels associated with quitting. But the net effect of vaping on your body right now, on your cortisol, your skin, your circulation, your lung function, and your recovery from exercise, is significantly negative. It is adding to the load your body is already managing.
The way to quit without gaining weight is to replace the habit with something that does not involve eating, increase protein during the transition to manage appetite changes, keep training consistent, and lean on the structured eating pattern above so there are no large gaps in the day where hunger and habit collide. It is manageable. It just needs to be planned for rather than white-knuckled.
Katrin, I want to be straight with you.
The things in this brief will help. Increasing the intensity of your training, addressing the iron deficiency, building a floor routine for hard weeks, eating in a way that supports your hormones rather than fighting them. All of it will move things. You will feel better. Some of it will happen quickly.
But the wired-but-tired pattern, the belly fat that does not respond to what you eat, the hair changes, the bloating, these are not things a better gym programme is going to fully resolve. They are symptoms of a hormonal and metabolic picture that deserves a proper look. Standard blood panels often miss what is actually happening in perimenopause. Ferritin, free T3, cortisol rhythm, oestrogen and progesterone levels. There is more to investigate here, and you deserve an actual answer rather than more plans to push through on.
You have been running on less for long enough. Let us figure out why.
