# After the diet: why the maintenance phase decides the outcome

> Hormonal adaptations and adaptive thermogenesis persist for years after weight loss. What research on weight maintenance shows - and how the WOO® Intermediate Box structures that phase.

Most people can lose weight. What fails is the time afterwards. Research on weight maintenance paints a clear picture: the critical phase does not begin with the deficit but on the day it ends.

## What the body does after a diet phase

After weight loss, more changes than the number on the scale. Sumithran and colleagues documented in the New England Journal of Medicine in 2011 that the hormonal adaptations following a diet were still measurable a year later: **leptin** remained lowered, **ghrelin** elevated - the body keeps signalling hunger even though weight should long since be stable.

On top of that comes adaptive thermogenesis: energy expenditure falls further than the reduced body mass alone would explain. Fothergill and colleagues found this effect in a heavily weight-reduced group even six years later. In practice this means: returning to the old portion size after a diet is not "eating normally again" but eating too much relative to the new requirement.

## Structure beats motivation

Since the 1990s the National Weight Control Registry has been collecting data from people who lost at least 13.6 kg and kept it off for over a year. The analyses by Wing and Phelan show recurring patterns: a regular meal structure, a consistent breakfast, frequent self-monitoring of weight and a high level of everyday activity.

What is striking is what is missing: none of these strategies rests on motivation. They are all structural. That is exactly why a plan with fixed meals works better in the maintenance phase than the resolution to "eat more consciously". A defined period of 30 days is long enough to establish routines and short enough to be seen through.

## Fibre and the satiety axis

Fermentable fibres such as **inulin** are not digested in the small intestine but broken down by the microbiota in the colon into short-chain fatty acids. These fatty acids - propionate above all - stimulate the release of the satiety hormones GLP-1 and PYY. Chambers and colleagues showed in 2015 that targeted delivery of propionate to the colon reduced food intake and limited weight gain over 24 weeks.

The point is not that fibre makes you lose weight. The point is that it strengthens the satiety signal - in a phase in which your own hunger signals are working against you anyway.

## How the WOO® Intermediate Box is put together

The **[WOO® Intermediate Box](/en/shop/woo-intermediate-box)** is a structured 30-day programme with a detailed nutrition plan and menu suggestions for breakfast, lunch and dinner. It contains two coordinated products plus a WOO® shaker.

**[WOO® Metabolic](/en/shop/woo-metabolic-box)** is 67 % inulin, complemented by plant extracts, blackcurrant and mango fruit powder and a plant concentrate from around twenty fruit and vegetable varieties. **[WOO® Reset](/en/shop/woo-reset-box)** provides, among other things, L-glutamine, potassium, calcium, magnesium and a broad vitamin and trace element profile. The box is designed as a follow-on to the WOO® White Box programme - that is, precisely for the phase in which research sees the highest relapse rate.

## Frequently asked questions

**Why 30 days and not permanently?**
Because a defined period is more binding than an open intention. Thirty days is enough to automate meal structure and intake rhythm; after that the routine carries itself.

**Do I need to have completed a weight-loss programme first?**
No. The box is designed as a follow-on to a diet phase but also works as a standalone 30-day programme with a nutrition plan.

**Do the products replace meals?**
No. They complement the nutrition plan. Food supplements are not a substitute for a balanced and varied diet and a healthy lifestyle.
