The one thing that is always hard when attempting to transform your physique is looking after your diet (the planning, the cooking, the consistency and the cost). So I've got some good news/easy tips for you to make things a little more manageable!
Find a local M&S, ask what time their food goes on discount, arrive at said time and stock up for the next day. Obviously this is applicable to any supermarket chain, however, I've found that M&S locals have the best variety and quality of food. Especially for anyone involved in exercise. The above cost me less than £5, saving just under £10 in total. This has also meant that I have not needed to plan or cook any food for the day whilst out and about. Allowing me to chill out last night and enjoy some much need rest. I also am low on cash until the next pay day, so this is very much needed!
