Does Alcohol Really Impact Your Weight Loss?

A glass of wine at the weekend. A few drinks with friends. A G&T after a long day.

It’s part of life, and I’m not here to tell you to give it up completely.

But if you’re trying to make changes to your body composition, your energy, or your habits around food, it’s worth understanding how alcohol plays a role.

Because for a lot of women I work with, especially in their 40s and beyond, alcohol is often the piece of the puzzle that doesn’t get talked about enough.

So… does it affect weight loss?

In short: yes, it can.
But not just because of the calories.

Let’s break it down:

1. Alcohol affects how your body burns fat

Your body sees alcohol as a toxin — so when it’s in your system, your body stops burning fat and prioritises clearing the alcohol first.
This doesn’t mean one drink ruins everything. But if it’s a regular thing, it can slow down your progress.

2. It adds up quickly

A glass of wine might be 150 calories. A large one? Closer to 250.
A couple of drinks, plus a nibble board or takeaway… it stacks up fast.
Not in a guilt-trip kind of way, just something to be aware of if you’re wondering why the scale’s not moving.

3. It lowers your inhibitions

You know that “sod it” moment that hits after a few drinks? That’s not your lack of willpower. it’s literally alcohol messing with your decision-making.
You’re more likely to reach for snacks, order takeaway, or eat past fullness, and less likely to care in the moment.

4. It affects sleep — which affects hunger

Alcohol might help you fall asleep faster, but it disrupts sleep quality.
Poor sleep = more cravings, less energy, and a bigger struggle to stay consistent with your nutrition the next day.

So what can you do?

You don’t have to cut it out completely — but it helps to get intentional.

Choose your drinks ahead of time
Decide how many feels worth it
Eat a balanced meal beforehand
Skip the “just because it’s Friday” drink if you don’t actually fancy it
Notice how you feel after — and make decisions based on you, not the rules

Final thought


You don’t need to be teetotal to reach your goals — but if you’re stuck, tired, or feeling a bit “off,” it’s worth looking at how alcohol might be impacting your nutrition, energy, and consistency.
