What to eat, what not to eat

Reaching your weight-loss goal isn't just about the number of calories you consume every day. More important is the type of food you are eating. As Walsh says; "Don't worry too much about counting calories. When you eat clean it's difficult to overeat!"

You do, however, need to be strict with your food choices. Walsh says: "Cut out processed foods, sugar, caffeine, dairy, wheat and starchy carbohydrates like pasta, rice and bread. Make sure you drink plenty of water too, around 1.5-3 litres a day to flush out toxins and prevent your body from storing water."

Sticking to natural foods is key says Peck. "Stay away from anything high in salt, sugar or fat. And cook at home rather than eat ready meals or take-outs, unless it's a healthy option. Aim for 50% carbs, 20% protein and 30% fats. You can still drink alcohol, but only in sensible amounts, aiming for 2-3 alcohol free days a week.

"Foods to go for include unrefined whole grain carbohydrates, high-fibre breakfast cereals, whole-grain crackers, wraps, fresh fruit, sweet potatoes, seafood, lean red meat, chicken, turkey, game, eggs, nuts, nut butters, seeds, beans, tofu, yoghurt and olive oil.

"Finally – eat - then exercise, as this is the time when your body will need the energy most."
