The Mystery of the Keto Plateau

You have been tracking your macros, swapping bread for lettuce wraps, and staying active. Yet, the scales have stopped moving, or perhaps that sluggish feeling has returned.

The culprit is rarely a lack of effort. More often, it is the sneaky, hidden ingredients lurking in products marketed as "Low Carb" or "Keto-Friendly." In the world of modern food manufacturing, a clean label is hard to find, and a low-carb claim is not always what it seems.

The Serving Size Trap & The Accumulation Effect

In the UK, nutritional labelling requires manufacturers to display values per 100g, which is fantastic for transparency. However, manufacturers can still manipulate the "per serving" suggestions on the front of the pack to make a product look more favourable to a keto lifestyle.

• The Serving Size Illusion: A snack bar or condiment might boast "only 1.5g carbs per serving" on the front. But when you look closer, the serving size is unrealistically small—sometimes just a single teaspoon or a fraction of the pack.
• The Accumulation Effect: Whilst a tiny portion seems negligible, using multiple servings of a commercial salad dressing, processed snack, or heavy cream throughout the day quickly adds up. By evening, these unmeasured trace amounts can easily equate to 10g or 15g of unaccounted-for carbohydrates, quietly knocking you out of ketosis.

The "Franken-Sugar" Hall of Shame

Not all sweeteners are created equal. To maintain optimal ketone production, it is vital to understand the Glycaemic Index (GI), which measures how quickly a substance spikes your blood glucose and insulin levels.

• Maltodextrin: Frequently found in powdered sweeteners and pre-mixed spice blends, this ingredient actually has a higher GI rating than standard table sugar. It is a primary cause of unexplained insulin spikes on a keto diet.
• Dextrose and Maltitol: These are frequently used in commercial "sugar-free" confectionery. Maltitol is particularly notorious for raising blood glucose levels and causing severe digestive discomfort.
• The Clean Solution: At Finally., our philosophy is simple: we never use or support artificial sweeteners. Instead, we champion natural, plant-and-fruit-based alternatives like erythritol, stevia, and thaumatin (extracted from the West African Katemfe fruit). These options have a zero glycaemic impact and form the pure foundation of our range.

The Protein and Fat Traps: It’s Not Just About Carbs

When a plateau hits, we instinctively blame carbohydrates, but your body’s metabolic biochemistry is more complex than that.

The Whey Protein Spike

While keeping carbs low is rule number one, the type of protein you consume matters. Highly processed, fast-digesting proteins—particularly whey protein isolate and concentrate—are highly insulinogenic. Even though whey doesn't contain sugar, it can trigger a rapid, significant spike in insulin. Because insulin is your body's primary fat-storage hormone, this sudden surge can abruptly halt fat burning and disrupt ketosis.

The "More Fat Is Better" Myth

Another common pitfall is consuming too much fat in the diet. While keto is a high-fat lifestyle, your body will always burn the fat you eat before it taps into your stored body fat. If weight loss has stalled, you might simply be over-consuming dietary fats.

Furthermore, processing high amounts of dietary fat requires a robust metabolic setup. Many individuals face underlying difficulties metabolising fat efficiently—whether due to sluggish bile production and gallbladder issues, or a lack of the critical micronutrients needed to support the cellular ATP energy cycle.

We will be diving deep into the science of whey protein, fat malabsorption, and the micronutrients driving the ATP cycle in upcoming posts, so keep an eye out.

The Silent Disruptors: Stress and Cortisol

Sometimes, the issue isn't what is on your plate at all. High stress levels and elevated morning cortisol can trigger gluconeogenesis (where the liver creates glucose from non-carbohydrate sources), raising blood sugar and locking your fat cells shut.

Look out for a dedicated post soon on how to manage stress and cortisol to break through stubborn weight-loss plateaus.

Sneaky Culprits in Your Kitchen

Perform a quick audit of your cupboards for these common offenders:

• Spice Blends: Many supermarket "Taco", "Cajun", or "BBQ" rubs utilise cornflour, wheat flour, or sugar as cheap bulking agents and anti-caking tools.
• Condiments: Balsamic vinegar, sriracha, and certain "sugar-free" barista coffee syrups are often loaded with thickeners, fruit concentrates, or hidden sugars.
• Processed Meats: British sausages, burgers, and deli meats frequently contain rusk, breadcrumbs, or dextrose as binders. Always look for premium, high-meat-content options.
• Dining Out: Be wary of restaurant omelettes and scrambled eggs; some commercial kitchens add pancake batter or milk blends to the eggs to make them fluffier.

Decoding the UK "Traffic Light" System for Keto

Most pre-packaged foods in the UK feature the red, amber, and green traffic light symbols on the front. While these are designed to help the general public, they can be incredibly misleading for the keto community.

• The "Green" Trap: A product may have a green light for "Sugar" but still be packed with complex starches that do not trigger a red light, but will absolutely kick you out of ketosis. Conversely, healthy, natural fats often trigger a "Red" warning for fat and saturates, which we know are essential clean fuel sources on keto.
• The UK Carbohydrate Advantage: Unlike American labels, UK nutritional panels list "Carbohydrates" and "of which sugars" separately. In the UK, the main "Carbohydrate" figure already excludes fibre. This means you do not need to do complex deductions to find "Net Carbs"—the carbohydrate number you see on a UK label is exactly what impacts your body.
• The Starch Gap: Always look at the difference between "Carbohydrate" and "of which sugars." If a product has 15g of carbs but only 1g of sugar, that remaining 14g is starch. Starch is simply a long chain of glucose; your body turns it into blood sugar almost as quickly as white granulated sugar.

How to Read a UK Label Like a Pro

Ignore the colourful lights on the front, flip the packet over to the nutritional table, and follow these three rules:

• Check the 100g Column: Suggested serving sizes are often tiny. Comparing per 100g gives you the true mathematical percentage of the product that is carbohydrate.
• Scan the Ingredients for Hidden Names: Look for words ending in "-ose" (sucrose, fructose, dextrose), maltitol, whey protein, as well as modified starches, wheat rusk, and maltodextrin.
• The "5g Rule": As a general benchmark for manufactured goods, if a product has more than 5g of total carbohydrates per 100g, proceed with caution – depending on the portion size. NOTE here that in the UK, in the nutritional values table, polyols must legally be listed as carbohydrates and then listed also as polyols. E.g. our erythritol-based sweeteners will show almost 100% carbohydrates! However, you will see that they are specifically polyols (sugar alcohols).

Ingredient Safety Ratings

When scanning ingredient lists in the UK, use this guide to identify which sweeteners and additives support your goals.

* It is only fair to clarify that while many non-nutritive sweeteners (natural or artificial) pass through the body without a glycaemic impact, the brain is incredibly clever. For those with insulin resistance, the mere taste of sweetness can trigger a sensory insulin response, potentially stalling ketosis. We never promote a diet reliant on sweetness as a rule; however, when it is required, we must be wise and choose natural options that minimise this metabolic risk.

How to Break the Stall: Your Action Plan

If your progress has slowed, simplify your approach for one week. Focus on whole, single-ingredient foods, keep an eye on excessive dietary fat intake, and scrutinise every label for hidden fillers or insulinogenic proteins.

To help you navigate this transition, we are incredibly excited to introduce two new clean-label products:

• Finally. Katemfe: A premium erythritol blend infused with natural thaumatin protein, providing flawless sweetness!
• Finally. Katemfe Collagen: The ultimate 100% protein sweetener. Sweetened entirely with natural Katemfe fruit protein, this pure collagen base can be used in absolutely any drink or recipe where sweetness is needed. Best of all, because collagen does not thicken or alter baking mechanics, it adds clean, non-insulin-spiking protein without affecting the texture of your bake.

At Finally., we completely vet every single ingredient to ensure our products are entirely free from hidden fillers, starches, or cheap artificial sweeteners. When you choose our range, you are opting for absolute formulation transparency and real metabolic health.
