Generally I would hate to be red-faced in society and would therefore confront the issue directly face to face to avoid a face off at a later date. Let's tackle the issue of how to lose weight on the face in right earnest.
Additional fat on the face is the result of general overweight state. Face is perhaps the smallest portion of the body and hence has fewer areas like the cheeks and chin where the fat could accumulate. Therefore additional fat is a result of multiple factors. The diet, life style, state of mind and attitude towards healthy living.
A fat, chubby and double chin face does not necessarily come by age. Yes, age is a factor as it retards metabolism resulting in excessive fat accumulation on the muscles. While there is no single remedy or a quick fix, a number of actions would help individuals in attaining their goals of weight loss on the face.
1. Drink in moderation.
Excessive intake of alcohol increases dehydration. This results in the body retaining excessive water including in the facial muscles. This gives rise to the state of "chubby" face and double chin. As an antidote, take around 10 to 12 glasses of water daily to avoid water retention and to detox the body.
2. Do regular exercises to lose weight in general.

3 The most important strategy is to regulate your diet and life style.
Eat plenty of proteins and fibers. Reduce carbohydrates and fats. Take enough salads, boiled, steamed, poached or roasted products in your food. With this you must also regulate the food timings. Regulate your meal timings and stick to that. Reduce salt in your food. Salt helps in water retention in the body.
4. For those who have access to the art of Yoga,
I would highly recommend the Pranamaya exercises. These are breathing exercises and give wonderful results. It is said that the yoga facial exercises can tone up all the 57 facial and neck muscles and tone up the face, resulting in weight loss on the facial muscles.
Let's face the issues today to avoid a long face tomorrow. A Latin proverb says that "A smiling face is half the meal", literally one may have to half the meal till one starts smiling. If you are really serious to lose weight on the face fast, follow the techniques seriously. The results will start showing quickly.
