How can you enjoy sugar without gaining weight, fuelling cravings or crashing later in the day? The answer, surprisingly, is not to cut it out. In today’s episode, Professor Tim Spector and Professor Sarah Berry discuss which forms of sugar affect your blood sugar levels most, and what small changes you can make today to reduce the impact. They also explore how sharp blood sugar spikes and dips may affect hunger, energy, inflammation and long-term health. By the end of the episode, you’ll know how to spot hidden sugars, how to avoid the afternoon slump and energy crashes, and, most importantly, how to enjoy cake with less impact on your blood sugar. Sugar is not the enemy.
