17-tonne tank smashes through 13ft-high London wall to highlight UK's 'other' energy crisis

A 17-tonne tank has spectacularly crashed through a wall in London, drawing attention to Britain's "other" energy crisis.

The towering 13ft 'wall' at Tower Bridge was dramatically demolished by the tank, following research that showed 72% of adults hit a metaphorical wall multiple times each week.

On average, Brits hit this wall twice a week and lose nearly 37 minutes of productivity when it happens – amounting to almost 78 wasted hours a year.

Nearly half (45%) report feelings of fatigue during these moments, while 40% feel unmotivated, and 37 % lack concentration.

The study of 2,000 adults revealed others become irritable (27%) and hungry (12%) after hitting a wall.

The wall, designed to represent the high carbs and sugar-filled snacks 76% typically reach for to boost their energy, was obliterated by Grenade founder Alan Barratt, driving the protein brand's vibrant orange 'tank'.

However, while 78% acknowledge the food they are fuelling themselves with could be to blame, 52% are not confident in identifying the foods causing them to feel fatigued and lack focus.

Neal Duffy, from the protein bar brand, said: "We're a nation of hustlers, so we need to fuel our bodies the right way. "Sugar isn't the enemy – it just needs to show up at the right time and in the right amount."

The research also found 39% choose their snacks based on convenience rather than nutrition, although 34% are interested in learning more about nutrition and switching to healthier options.

Smarter snacking options are on the rise. Over half, 53%, of Brits are open to trying new alternatives, with 36% actively seeking high protein, low sugar snack options.

Sports nutritionist Lois Bright chimed in: "Being more mindful about what we eat and when we eat it will help us manage our energy levels more efficiently.

"As a nation, we need to understand what we're putting into our bodies and be realistic about what we'll get out. "Choosing drinks and snacks which are high in protein is a simple switch we can all make to ensure we have the stamina to power through our busy days. ".
