I recently had an enlightening conversation with Danielle, our leading female personal trainer, about the unique challenges women face in their fitness journeys—particularly around their menstrual cycles. Now, before the guys start tuning out, remember—this is something half the population deals with every month. It’s a topic worth discussing because, let’s be real, women deserve major credit for managing this while staying committed to their fitness goals. In my opinion, women are the true powerhouses of our planet.
Our discussion naturally expanded into how various hormones play a role in fat loss and muscle gain.
If you know me, you know I’m a science geek at heart. I can’t help but dive into the science behind fitness whenever I get the chance. So, here’s a quick rundown on how different hormones can impact your fitness journey—no Ph.D. required:
Insulin helps regulate blood sugar levels. Too much insulin can lead to fat storage and weight gain, while the right amount keeps your blood sugar steady and minimizes fat storage.
Testosterone is key for muscle building, strength maintenance, and fat management. Low testosterone can increase body fat and decrease strength, whereas higher levels help you build muscle and burn fat efficiently.
Estrogen is vital for reproductive health and bone strength. An imbalance can cause fat to linger, but when balanced, it helps distribute fat evenly.
Cortisol, known as the stress hormone, can trigger hunger and lead to belly fat, which can slow your metabolism.
Adrenaline speeds up your heart rate and gives you energy bursts. Short bursts of adrenaline can boost your metabolism and help you burn more calories.
Your thyroid controls how quickly your body uses energy. Low thyroid levels can slow your metabolism and lead to weight gain, while balanced levels support efficient calorie burning.
Before I wrap this up, let’s clarify a couple of fitness terms you’ve probably heard:
BMR is the number of calories your body needs at rest to maintain essential functions.
A calorie surplus occurs when you eat more calories than your body burns (including BMR and activity). This surplus leads to weight gain, as extra energy is stored as fat.
A calorie deficit happens when you eat fewer calories than your body burns. This deficit leads to weight loss, as your body taps into stored fat for energy.
Hormones can influence your appetite, potentially pushing you into a calorie surplus and causing weight gain. They also affect how efficiently your body handles calories, impacting your BMR.
Everyone’s BMR is different. For example, women typically have a lower BMR than men due to differences in muscle mass and body size. A man might burn more calories at rest simply because he has more muscle, while someone with hypothyroidism might have a lower BMR due to an underactive thyroid.
Regardless of your hormonal situation, one principle remains consistent:
