The Diabetes Coach
Helping you reverse diabetes.
With or without a jab. Mounjaro · Ozempic · Wegovy →
- 1Control blood sugars firstEverything else follows from this.
- 2Use fat, not carbs, for fuelSo your body finally burns what it’s been storing.
- 3Address the “addiction”, cravings and self-sabotageThe part every other plan skips.
You’re not lacking willpower. You’ve been fighting a hormone – and no one ever told you which one.
Darren TebbenhamOne message, and I’ve built a career on it: this is reversible. See the five markers →
The whole approach, in three steps
Measure. Understand. Change.
MeasureWhere are you now?
Five simple markers you can check yourself in the next two minutes. No clinic, no appointment, no kit.
UnderstandWhat’s really driving it
Insulin deals with excess carbs in your diet and in turn stops you burning fat. Low-calorie dieting fails to nourish your body (and mind) with what it needs – and meds alone leave the root cause untouched.
ChangeMake it permanent
New behaviours to create the outcome, then new habits so your result holds. New thinking to make that switch – otherwise regain is inevitable.
Step one · Are you insulin resistant?

The Biology of Weight Loss and The Psychology of Weight Loss – why your body holds onto fat, and the patterns that make it come back. Everything on this page, in full. No call, no obligation.
Take your time. When you’re ready, the free week will still be here.
Step two · Insulin, hyperinsulinaemia and blood sugar
Understand.
One mechanism sits underneath almost all of it. Once you see it, you can’t unsee it.
- 1Consuming too many carbohydrates – good, bad and ugly – means too much insulin in your blood.
- 2That’s called hyperinsulinaemia, and it always – without exception – happens alongside insulin resistance.
- 3Too much insulin causes many major health conditions, not just the number on your blood test.
- 4And it stops your body burning fat for fuel – which is why the effort you’ve already put in never seemed to pay.
Treated with medication alone, the root cause is left completely untouched. You are managing symptoms, not reversing anything.
The newer weight-loss drugs – Mounjaro, Ozempic, Wegovy – can genuinely work. But only in conjunction with step three. What a jab can and can’t do →
Step three · Habits that hold
Change.
You must change your behaviours to create new outcomes – and your habits, the natural ways of thinking and acting, to maintain them.
Want some help?
The Ultimate 10-Week Challenge gives you three things.
Nutrition coachingSo the change sticks
Simple, sustainable eating that lowers your insulin, controls blood sugar and lets your body use fat for fuel again.
Live strength trainingBuilt for beginners
Take back control of your metabolism. Muscle is where glucose goes – building it is one of the most direct ways to improve insulin sensitivity.
Accountability & mindsetThe part everyone skips
Stop the self-sabotage, beat the cravings, and end the on-it / off-it cycle for good. This is the psychology I’ve built a career on.

Real results from the 10-week challenge
Before you decide
What your free week actually looks like.
No card, no commitment, no being put on the spot. Here’s exactly what happens.
You get full access to everything
Nothing held back. The nutrition and meal plans, the live onboarding, and access to all the resources you need.

The first week is free.
Let’s get you inside. See how it works, meet the group, and feel the difference before you decide anything.
Start your free week →After the free week, the 10-week challenge is £450 – or 3 × £150 monthly.
That’s £45 a week – less than a single personal training session.
Nothing to pay to start. Stop at the end of week one and it costs you nothing.
Nothing to lose – except the stone and a half our last group averaged.
And everything to gain. Food freedom. No more dieting. No longer stuck.
Common questions
Reversing type 2 diabetes – your questions.
Can type 2 diabetes really be reversed?
For many people, yes. The clinical term is remission – an HbA1c below 48 mmol/mol (6.5%) sustained without glucose-lowering medication. It is not a cure and it is not guaranteed: blood sugars can rise again, which is why the NHS and Diabetes UK prefer “remission” to “reversal”. What is well established is that sustained weight loss and lower insulin exposure give you the best chance of getting there. Your own numbers and medication are a conversation for your GP.
What’s the difference between reversal and remission?
Everyday language versus clinical language. Most people say they want to reverse their diabetes; doctors say remission, because the underlying tendency doesn’t disappear and the condition can return if the weight goes back on. Practically, you are aiming at the same thing: blood sugars back in the normal range and staying there, without medication doing the work for you.
How do I know if I’m insulin resistant?
Start with the five markers on this page: a waist more than half your height, a doctor already using the words prediabetic or type 2, blood pressure or cholesterol medication, worry about memory and mood, and a weight pattern that goes down, comes back and is now stuck. Two or more makes insulin resistance very likely. An HbA1c blood test from your GP will confirm where you sit in terms of blood sugar. But problems with insulin often begin decades before that test shows anything. If in doubt, take back control today.
Do I have to come off my medication?
No – and please don’t change anything on your own. This is nutrition, strength training and habit change. Every decision about metformin, blood pressure tablets, statins or a GLP-1 stays with your GP, pharmacist or prescriber. What often happens is that as your numbers improve, they review your doses with you. And besides – medication should help you take back control, not be the control. A GLP-1, for example, can curb your appetite while you get on with changing your diet for the longer term. The meds aren’t the cure.
Does this work if I’m on Mounjaro, Ozempic or Wegovy?
Yes – it’s built to work with or without a jab. A GLP-1 quietens appetite, but it doesn’t decide what you eat, protect your muscle, or change your habits for when you stop. Used alongside the right dietary change, the jabs can work well. Used instead of changing anything, the weight tends to come back.
Is it online or in person?
Fully online, wherever you are. Live workouts every Monday, Tuesday, Wednesday and Thursday morning with Coach Allison, weekly live coaching, and weekly check-ins with personal replies. Camera off if you’d rather, and no equipment needed to start.
What does it cost?
The first week is free – no card, no commitment. After that the Ultimate 10-Week Challenge is £450, or 3 × £150 monthly, which works out at about £45 a week. Nothing is due until the free week ends, and if you stop there it costs you nothing.
Is this suitable for type 1 diabetes?
This programme is designed for type 2 diabetes, prediabetes and insulin resistance. Type 1 diabetes is an autoimmune condition and is not reversible, so the goal here doesn’t apply in the same way. People with type 1 can still benefit from strength training and better nutrition, but that must be managed with your diabetes team. A better diet, less reliance on carbohydrate for energy and more muscle available to store glycogen can mean lower insulin requirements and fewer highs and lows – though every dose change is theirs to make, never yours alone.
This page is about type 2 diabetes, prediabetes and insulin resistance. It supports nutrition, training and lifestyle change and is not medical advice. It does not replace guidance from your GP, pharmacist or prescriber – never stop, start or change any medication without speaking to them first.
