How can supplements aid weight loss?

Supplements can support weight loss in many ways, but first it must be said that all successful weight loss comes down to maintaining a calorie deficit. Here’s how supplements can support that objective:

Reducing appetite

If you’re less hungry, you’re more likely to maintain a calorie deficit and not consume too much. Some supplements can help you feel more full or less hungry, which could help you to meet your calorie goals.

Boosting energy

The other crucial part of the calorie-balance equation is how many calories you’re burning — and good workouts require lots of energy. Supplements that can support your concentration, energy levels, and stamina can make a big difference towards calorie burning at the gym.

Supporting metabolism

When it comes to burning calories, you want to make sure your metabolism is working efficiently to aid weight loss. Some supplements can help support fat burning and preserve muscle mass to target fat loss, others can make sure your cells are getting the energy they need from the food you eat.

 

Supplements for weight loss

1. Diet Whey Protein

Protein… some people may associate it with muscle-bound bodybuilders, but did you know an increase in protein in the diet has been shown to increase weight loss and fullness?

Whey protein is one of the most popular supplements for weight loss. There’s good reason why — it’s fast absorbing and has a high amino acid content, which has various benefits for the body. In addition to supporting recovery, maintenance and growth of muscles, it has also been associated with increased fullness and weight loss.

In one double-blind 12-week study, overweight participants went on a diet where the calorie intake was reduced by 500kcal a day.1 Participants were asked to consume a whey protein drink or a ready-to-mix beverage with the same number of calories 20 minutes before breakfast and 20 minutes before dinner.

While both groups lost a significant amount of weight, greater weight loss was seen in the group consuming a whey protein-based drink. On top of this, those who consumed whey protein for 12 weeks lost significantly more body fat and less lean muscle.

Diet Whey protein is one of the best dietary supplements for weight loss — try consuming a scoop of impact diet whey with milk, low-fat yoghurt or water first thing in the morning, after a workout or before bed.

Summary: Whey protein can help to satisfy your hunger while providing amino acids to preserve muscle tissue. It can also support weight loss thanks to increased satiety and reduced calorie intake.

 

2. L-Carnitine

What actually is L-carnitine? It’s a natural chemical that is created in the liver and kidneys from the amino acids lysine and methionine. Good to know… so why is it so special then?

L-carnitine has a range of benefits in the body, number one being its role in aiding weight loss. It acts by transferring long-chain fatty acids into mitochondria where they can be oxidised to produce energy… this makes the body burn stubborn fat stores for energy.

Recent scientific data has indicated that L-carnitine also plays a role in preventing cellular damage from exercise stress, and supplementation can actually have benefits for training, competitions and recovery.6

Support your weight loss diet and training regime by taking two tablets of L-carnitine before meals twice daily.

Summary: L-carnitine supports the metabolism of fat, which can help make your metabolism more efficient, as well as exercise recovery.

 

3. BCAA

BCAA stands for branched chain amino acids. If you’re not familiar, amino acids are the building blocks of proteins. BCAAs are a group of three amino acids considered “essential” — that is, unlike the other non-essential amino acids, they must be consumed in the diet. BCAAs are made up of leucine, isoleucine and valine, and are thought to be some of the only amino acids directly related to muscle recovery that can also be used as a source of energy in the body.

All makes sense… but how exactly do BCAAs help with weight loss?

Supplementing with BCAAs has been shown to help regulate the body’s insulin levels and play a large role in several different metabolic reactions.2 And in a scientific review, there was emerging evidence showing the metabolic roles of leucine has some effect on weight loss.3

To aid weight loss, supplement with BCAAs first thing in the morning, and before and after a workout.

Summary: BCAAs help to support healthy muscles and optimise metabolism to support weight loss.

 

4. Green Tea Extract

The British are always drinking tea. Well, it turns out the occasional cuppa has health benefits. If it’s a cup of green tea, that is. Many studies have shown the drink to have health benefits, weight loss among them.

So, how can green tea help you lose weight?

Green tea has been labelled a metabolic booster by some… but it’s not quite that simple. It contains chemical compounds called polyphenols — catechins to be precise.

In one study it was found in a sample of participants that the consumption of catechins were seen to have a positive effect for weight loss.4

To compare the effects of catechins with other chemicals also suspected to increase metabolism, the effect of weight loss with regular caffeine consumption was also investigated, but no significant decrease in weight was seen in this instance.

Overall, results from the scientific study provided evidence to suggest catechins, specifically epigallocatechin gallate, can have benefits for weight loss and weight maintenance.

So consuming green tea extract as part of a balanced diet and in combination with a good training regime can support weight loss.

Summary: Green tea contains catechins, which seem to have some benefits for weight loss and management.

 

5. Omega 3

Last but by no means least is Omega 3. We’d be surprised if you’d never heard of omega 3 before, but we’ll bring you back up to speed regardless! Omega 3 is an essential fatty acid we get from nuts, seeds and certain types of fish, such as salmon, sardines and mackerel.

Omega 3 contains two essential fatty acids: DHA and EPA. Note the word “essential” — this means we must consume these fatty acids through our diets to live and function because our bodies cannot produce them. In the UK it’s advised that we consume at least one portion of fatty fish a week, but some people may struggle to follow this advice.

One study investigated whether appetite could be affected by omega 3 fatty acids when included in a calorie-restricted diet.5 A positive relation between omega 3 and fullness was observed over the eight weeks of the study, and it was concluded that omega 3 intake can help modulate appetite and may have uses for weight maintenance.

So to help aid your weight loss, supplementing with omega 3 capsules once to three times a day may also help regulate your appetite while also aiding your metabolism for burning fat.

Summary: Omega 3s are good fats to include in your diet to support satiety and a healthy metabolism, which are both crucial for weight loss.
