meal replacement and weight lose

A meal replacement drink is one intended as a substitute for a solid food meal, usually for purposes of weight loss. Often such drinks are in the form of a health shake.
Meal replacement drinks, which include required vitamins and minerals.
Bodybuilders sometimes use meal replacements to save food preparation time when they are eating 5 to 6 meals a day.
To lose weight we need to take in fewer calories than our body needs.
In general, you replace two meals - usually breakfast and lunch - with a meal replacement shake, soup or bar and then have a 600-calorie healthy meal in the evening.
even ready meals can be included if you can’t be bothered to cook yourself a meal from scratch in the evening.
Most plans also allow two to three 100-calorie snacks a day and recommend drinking six to eight glasses of water or low-calorie drinks.

Quantity of weight loss

As with any reduced-calorie diet, the amount of weight you’ll lose will depend on the number of calories you consume.
In general, an intake of 1,200 to 1,400 calories a day, will result in a weight loss of around 1-2lb each week.

Healthy meal replacement products

By law, meal replacement products must provide the recommended amount of nutrients needed for good health and their composition must match to definite principles defined by a European Directive.

According to this Directive - the guidelines for which are based on research looking at the nutritional needs of dieters - meal replacement products must contain between 200 and 400 calories, at least 25 percent protein and 23 vitamins and minerals.
With regard to fibre, most products contain around 5-6g. Healthy eating guidelines recommend adults have 18g fibre daily.
Most plans also recommend including fruit and veg as snacks and as part of your main meal.
pros
Several studies have found that meal replacements are as effective as traditional calorie-counted diets in terms of helping people to lose weight in the short term.
Better still, the commonly held belief that meal replacements only help people to lose weight temporarily doesn’t seem to be supported by current research.
In fact, long term follow up studies suggest that meal replacements may actually help people to keep their new lower weight.

Cons

Firstly, most studies have provided meal replacement products free of charge - it’s unknown whether people would be as likely to stick to the diet if they had to buy the products themselves.

Secondly, most studies have used meal replacements as part of a comprehensive programme, which includes support and dietary advice from health professionals.
One of the other main problems with meal replacement diets is that on their own, they do little to educate people about their eating habits.
While replacing high-calorie breakfasts and lunches with a shake, soup or bar will almost certainly result in weight loss, returning to poor eating habits once you stop taking the products means you will almost certainly pile the weight back on again.
