And when it comes to dieting, whether a person sticks rigidly to their programme or not, Martena offered a few key points that can help.
High protein diet
She said: “If you struggle with over doing it with your food on holiday, try prioritising your protein in meals.
“This will help keep you fuller for longer and you’re less likely to overeat.”
The best sources of protein can be found in foods such as:
Lean meats – beef, lamb, veal, pork, kangaroo
Poultry – chicken, turkey, duck, emu, goose, bush birds
Fish and seafood – fish, prawns, crab, lobster, mussels, oysters, scallops, clams
Dairy products – milk, Greek yoghurt, cottage cheese
