Ideal Carbohydrate Intake

How well a body handles carbohydrates depends on a network: insulin signaling (TCF7L2, IRS1), glucose transport (SLC2A2), fat oxidation (PPARG, ADRB2), and circadian regulation (CLOCK, MTNR1B) all interact to set the metabolic response to a given carb load. There’s no single "carb gene" — the answer comes from how the network reads collectively.

Carriers of clusters of variants in TCF7L2, PPARG, and SLC2A2 are associated with reduced carbohydrate tolerance — higher post-meal glucose, faster fat storage, and stronger benefit from lower-carb patterns. Carriers of typical-function networks are associated with broader carbohydrate latitude; high-carb patterns work fine without metabolic penalty.

Meal sequencing matters: vegetables and protein before refined carbs blunts glucose response. Walking ten minutes after a meal reduces the post-prandial peak in nearly all variant patterns. Resistance training raises insulin-independent glucose disposal. Sleep is the multiplier — under-slept clients show worse glucose responses to the same meal regardless of variant.

The "I do better low-carb" and "I feel best eating a lot of carbs" experiences aren’t both equally true at the level of biochemistry. Which network you carry decides whether the macro split you’ve drifted into matches your wiring — or whether tuning it is the missing variable.
