Keeping a food diary really works

Ask anyone about their eating habits and they will tell you their diet is better than it really is. We tend to have misconceptions about what we really eat, not being mindful of the amount of processed food we eat or the units of alcohol we drink. This is when a food diary is helpful as a reality check.

Reasons for keeping a food diary

The main reason is mentioned above – it’s a reality check and it’s not until you keep a food diary that this hits home. If you are totally honest then you will probably look back over a few days with your head in your hands. People often tend to change eating habits once staring a food diary and this has obvious benefits.

How to keep a food diary

This is the easy bit. You can just scribble it all down on a sheet of paper or be more organized and use a computer spreadsheet. Simply write everything you eat for a period of at least 3 days including one work day and one none work day (ie thursday, friday, saturday). There is no reason why you can’t keep a food diary for a whole month if you feel you are eating better as a result. Be sure to include all the following information;

  • The day of the week
  • The time of day
  • The food (of course!)
  • Any further details – tinned/ready meal/fresh etc
  • Add all fluids including water, alcohol, tea, coffee, soft drinks..
  • Be completely honest!!

Do this for a few days and it will change your perspective on food!

The facts about alcohol

We all know alcohol is bad

Many people enjoy an occasional beer or glass of wine, maybe more than that. Alcohol is a part of social life but needs to be consumed with caution. From a weight loss perspective alcohol is high in calories, low in nutrients and usually ends up around the mid section. Here’s why.

Alcohol is high in calories

The best way to illustrate this is comparing the food groups gram for gram.

Food Group Calories per gram
Carbohydrates 3.75kcal
Protein 4kcal
Alcohol 7kcal
Fat 9kcal

We can clearly see that gram for gram alcohol has nearly double the calories of carbohydrates and proteins and almost as many calories as fat, yet we wouldn’t dream of going out with friends downing glass after glass of fat!! The calories in alcohol are often overlooked but may need seriously addressing to see changes in weight loss and health.

Current recommended maximum alcohol intake is 28 units for men and 21 untis for women.

Alcohol statistic

A small glass of wine of bottle af beer every day with a meal doesn’t seem like much. Over 1 year this amounts to thousands of calories, the equivalent to 1 stone in weight.

The body burns calories from alcohol first

When we drink alcohol it is broken down differently from normal food. The liver releases enzymes to break alcohol down into energy but this only happens at a slow constant rate. This energy is used first before the energy from food (especially that greasy burger you had on the way home!) and you can guess where the excess calories end up being stored. As body fat.

The bottom line with alcohol is the same as any other treat – consume in moderation. Be aware of the calorie content and if you drink regularly consider at least one or two alcohol free days each week.

The importance of a good breakfast

Breakfast is probably the most neglected meal of the day, yet it still remains the most important. We need to look closely at what we eat first thing as it kick starts the rest of the day.

How do we get it so wrong

Many people eat the wrong type of breakfast or even skip it altogether. A poor or non existent breakfast can play havoc with energy levels and concentration during the mornings work. By mid morning the body will go into starvation mode and this is where high sugar or processed snacks are eaten. From a calorie perspctive, studies have shown that a high sugar breakfast can lead to 40% extra calories being consumed during the remainder of the day. That’s a lot of calories.

Start the day right

Aim for a breakfast low in sugar. This is harder than it sounds as many of the convenient breakfast cereals available are high in sugar. This is true of some of the cereals considered to be healthy, often as much as 25% sugar – read the ingredients for more info! Low GI meals are best and if you aim for these prepare for better energy, weight loss and concentration.
