You Know What to Eat… So Why Can’t You Stick to It?

If you feel like you already know what to eat but still cannot seem to stay consistent, you are not alone.

So many of the people I work with tell me the same thing. They have read the books. Followed the plans. Saved the high-protein recipes. Started strong on Monday. Yet when life gets busy, stress creeps in or progress slows, the old patterns return. The frustration is real. It can feel like a personal failure.

But in my experience, this is rarely about willpower. It is usually about structure, strategy and how well your body is actually being fuelled.

One of my lovely clients once said that I helped her put into practice what she already knew to be true. She did not lack information. She lacked a framework that worked in real life. She was stuck in:

• Mid-morning hunger pangs
• Afternoon sugar crashes
• Feeling out of control around food in the evening
• Starting the day well but “falling off track” later
• Constantly thinking about food

When this pattern repeats, confidence drops. You start questioning yourself. You might even think you are lazy or undisciplined. You are not. Very often, your body is simply under-fuelled earlier in the day and trying to catch up later.

When your meals are low in protein or too small to sustain you, blood sugar rises quickly and then drops just as fast. When it drops, your brain does not calmly suggest a balanced meal. It pushes for quick energy. Usually something sweet or refined.

This is not a mindset flaw. It is physiology. When your body feels fuelled and steady, your brain finds it much easier to make calm, consistent choices. That is why I focus first on blood sugar balance and realistic daily structure rather than strict rules or calorie counting.

When someone comes to work with me, I am less interested in what they eat in theory and more interested in how their day actually flows. We look at questions like:

• Where are the long gaps between meals?
• Is protein missing at breakfast?
• Are lunches rushed or skipped?
• Is there under-fuelling during busy periods?
• Is the evening becoming a catch-up zone?

Often, small adjustments in timing and composition of meals make a significant difference. It is not about perfection. It is about creating a rhythm that supports energy, mood and appetite.

If you recognise yourself in any of the following, your body may be asking for more consistent fuel:

• Strong cravings for sugar or refined carbs in the afternoon
• Feeling shaky, irritable or foggy between meals
• Grazing in the evening despite eating “well” earlier
• Feeling virtuous during the day but out of control at night
• Relying on caffeine to get through the morning
• Starting diets repeatedly but struggling to sustain them

These are not character flaws. They are often signs that your meals are not keeping you full or steady enough.

For some people, particularly if symptoms are persistent or more complex, functional testing can provide additional insight.

Depending on the individual, this might include:

• A comprehensive stool test to explore gut health and digestion
• Blood tests to assess iron status, vitamin D, thyroid markers or blood glucose patterns

Testing is not always necessary. Many people benefit simply from improving meal structure and balance.

However, if someone is doing all the right things and still struggling with fatigue, cravings or weight plateaus, testing can help us tailor support more precisely. It should always be used thoughtfully and interpreted in context, not in isolation.

If you are tired of knowing what to do but not doing it, start small. Here are three simple shifts to try:

1. Add Protein to Breakfast

Many people start the day with toast or cereal and very little protein. Aim to include a meaningful protein source such as:

• Eggs
• Greek yoghurt
• Nut butter
• Smoked salmon
• Tofu or a protein-rich smoothie

A balanced breakfast sets the tone for the rest of the day.

2. Eat Every 3 to 4 Hours

Long gaps often lead to the crash and grab cycle. Try building in regular meals or planned snacks so you are not running on empty. This is especially important on busy workdays.

3. Build Meals Around Protein, Fibre and Colour

Before thinking about calories, focus on composition. Start with:

• A source of protein
• Fibre from vegetables, pulses or wholegrains
• Colour from a variety of plant foods

This combination supports fullness, steadier energy and fewer sudden cravings.

Small shifts really can make a big difference when done consistently.

All of the above in practice can be really powerful – this is what one of my clients had to say –

“Claire has been just brilliant at helping me to put into practice what I knew to be true, but I didn’t quite have the oomph to achieve myself! She has helped me to change the way I eat completely and I feel entirely different – I’ve even lost some weight! I’ve learnt how to fuel my body properly to avoid hunger pangs and sugar crashes and I now have some great tools under my belt. In addition, Claire is friendly: firm but fair, practical and understanding – keeping me on track and accountable. She is a font of knowledge on all things nutrition and I would thoroughly recommend her to anyone who knows they need to make some dietary changes… It’s never too late!”

If you feel stuck between knowing and doing, please know that this is common and completely workable. With the right structure, realistic routines and meals that genuinely keep you full, things can feel very different.
