14-Day Sugar and Starch Elimination Reset
Berg structures the reset as a day-by-day journey: Day one begins glycogen depletion and water loss. Day two brings cravings as enzymes shift. Days three and four are the crisis point—dopamine receptors are at their lowest, cortisol spikes, and most people quit because of brain fog, irritability, and anxiety. He likens it to nicotine withdrawal, stressing that pushing through this exact window leads to improvement. Day five to seven brings dopamine receptor reset, reduced inflammation, elevated mood, and cognitive sharpening as ketones become the primary brain fuel. Days ten to fourteen see further weight loss, no cravings, and normalised dopamine sensitivity so that even the taste of sugar becomes overwhelmingly sweet. He warns that social habits—parties, family events—can still trigger old behaviors, but physically the compulsion is gone. The protocol is not just a diet but a neurological and metabolic rehabilitation.
On day one, liver glycogen is mobilized for fuel, releasing bound water. Insulin drops, signaling fat cells to release fatty acids, but the enzymatic conversion to ketones takes a few days, causing an energy lag and cravings. Simultaneously, dopamine receptors that were downregulated by chronic sugar stimulation remain low, creating a reward deficit. The brain perceives danger and elevates cortisol, producing physical and mental discomfort. By days 5–7, dopamine receptors begin to upregulate, and the body starts producing ketones efficiently, supplying brain fuel. BDNF increases, helping repair neurons damaged by years of glycation and insulin resistance. From day 10 onwards, fat adaptation is robust, hunger and cravings disappear because cells are finally fueled by stored body fat.
on day two is when the cravings kick in because your body hasn't adapted yet. Certain things in your body have to go from sugar burning to burning fat fuel... And the cravings might hit you pretty hard. What you have to realize is those cravings are going to go away very, very soon.
