Different Methods of Restricting

There is no one common strategy to restricting, which varies within when you eat, how much you eat, how often you eat and what you count. There are also different patterns that work better for some people, and I will simply discuss the pros and cons of many of these.

Eating one big meal/once a day (intermittent fasting): This schedule is often used by those with a busy schedule which allows them to avoid being confronted by many food related decisions.
+ easy to stay within a low limit, allows you to fall asleep feeling somewhat full, 'normal' sized meals can be had with family or significant others
- requires 18-22 hours between meals, night binges

3-4 Mini meals/day: For those who are surrounded by food through the day, controlled meals to keep from binges.
+ variety, normal eating timing can continue, 'always eating' just small amounts
- one big meal could lead to disaster, constant temptation

Repeated fasting: Fasting 1-2 days, with 'break' days (limited or free calories). This system takes a lot of control but often leads to the binge-fast-binge cycle.
+ rapid weight loss, temporarily relieves binge stress
- requires a lot of control, easy to fail

Each of these systems can be used with different levels of intensity. Personally, I'd recommend the first two over the last, but all are effective.
