Tom's tips

Tom Brennan from BodyLight kept me on the straight and narrow by explaining how I could have the odd 20-minute treat.

Curly Wurly: 20-minute walk

• HB Twister: 20-minute walk

• Cadbury's Flake: 40-minute walk

• Share bags of cinema sweets: 3.5-hour walk (forget about it, in other words)
