If you’re gaining weight around your stomach, hips or thighs despite eating the same and exercising, you are not imagining it — and it is not your fault.
Weight gain is one of the most common and distressing symptoms of perimenopause, and it is driven by hormonal change, not willpower.

What Actually Causes Weight Gain in Perimenopause?
Perimenopause changes how your body handles:
-
Blood sugar
-
Fat storage
-
Muscle
-
Stress hormones
Oestrogen normally:
-
Helps regulate insulin
-
Supports muscle tissue
-
Keeps fat distributed evenly
-
Protects against belly fat
As oestrogen fluctuates:
-
Insulin becomes less effective
-
Blood sugar becomes unstable
-
Cortisol rises
-
Fat storage shifts toward the abdomen
Your body starts storing more and burning less, even if your lifestyle hasn’t changed.

Why the Weight Goes to Your Stomach
When oestrogen drops or swings:
-
Cortisol rises
-
Insulin resistance increases
-
Fat is preferentially stored around the belly
This type of fat is hormonally driven and won’t respond well to calorie cutting.
This is why many women say:
“I’m eating less but gaining more.”
How PERI Supports Weight Regulation
PERI was designed to support the hormone systems that control fat storage and metabolism.
Oestrogen-buffering compounds
Red Clover & Soy Isoflavones
Help smooth oestrogen drops that trigger fat storage.
Dong Quai & Maca Root
Support hormonal signalling involved in metabolic balance.
Resveratrol, Hesperidin & Pine Bark
Support oestrogen receptor activity and circulation.

Blood sugar and metabolic support
Cinnamon Bark
Helps improve insulin sensitivity and blood sugar control.
Green Tea Extract
Supports fat oxidation and metabolic rate.
Stress and cortisol control
Siberian Ginseng
Helps prevent stress-related weight gain driven by cortisol.
Muscle and tissue support
L-Arginine, L-Lysine, L-Glutamine & L-Glutamic Acid
Support muscle maintenance and metabolic tissue.
Loss of muscle = slower metabolism.
Gut-oestrogen connection
Lactobacillus acidophilus
Supports healthy oestrogen recycling, preventing fat-promoting hormone imbalance.

FAQs
Is weight gain a sign of perimenopause?
Yes. Hormonal changes shift how the body stores and burns fat.
Why am I gaining belly fat?
Fluctuating oestrogen increases cortisol and insulin resistance, which promotes abdominal fat storage.
Will dieting fix perimenopause weight gain?
Often no — the root cause is hormonal, not calorie intake.
Is Arbor PERI designed to help with weight gain?
Yes. PERI supports oestrogen signalling, blood sugar balance, stress hormones and metabolic tissue.

Key Takeaway
Perimenopause weight gain is not about discipline.
It is:
-
Oestrogen volatility
-
Insulin resistance
-
Cortisol overload
-
Metabolic slowdown
Arbor PERI helps rebalance the hormone systems that control fat storage, metabolism and energy.
