Weight Loss Pitfalls: The Science of Choosing Low-Calorie Snacks and Healthy Beverages

What specific snacks are recommended during fat loss?

1. Preferred snacks
Dried fruits and vegetables, seaweed sheets, crab sticks, zero-calorie jellies, plain nuts, tofu products, naturally air-dried beef jerky, low-calorie protein bars, etc.
If cravings strike, these snacks can be consumed as small meals.

2. Snacks to consume in moderation
Dark chocolate, wholemeal biscuits, milk wafers, dried squid strips, raisins, etc.
These should be eaten sparingly—a small piece or portion at a time.

3. Snacks to avoid
Crisps and other puffed snacks, sweets, dried fruit, cakes, white chocolate, butter biscuits, spicy strips, ice cream, etc.
Now I'll share my favourite snack combinations to help you understand portion sizes clearly:
· A small piece of dark chocolate + ten nuts (pistachios, almonds or cashews).
· A small handful of blueberries + a cup of unsweetened yoghurt. This pairing greatly enhances the yoghurt's flavour.
· A small packet of low-salt seaweed + ten cherry tomatoes.
· Wholemeal fibre biscuits + a cup of unsweetened floral tea – a splendid afternoon tea pairing.
· One banana + two tea-flavoured eggs.
Finally, I must remind everyone: avoid visiting convenience stores before meals. When hungry, one tends to unconsciously purchase excessive snacks – do not test your self-control.

Beverages & Juices:
Take heed – do not consume calories by drinking!

Many of you enjoy drinks and juices, some even treating them as water, believing they contain little energy—a significant misconception.

Though drinks aren’t particularly energy-dense, they’re consumed quickly. Before you know it, a whole bottle is downed. This happens especially when dining out—a can is often paired with a meal without a second thought, or ordered alongside takeaway.

A 250ml can of cola contains 107kcal – equivalent to half a bowl of rice. Yet some people easily consume 3-4 cans daily. Similarly, readily available lemon tea drinks pack 260kcal per 500ml bottle, equivalent to one and a half bowls of rice.

Then there are fruit and vegetable juices. Take orange juice, for instance: a typical 100ml serving packs 40-50 calories, with bottles ranging from 250ml to 600ml. Beyond their substantial calorie content, these juices lack the dietary fibre found in fresh produce, leaving us largely consuming added sugars. In essence, what begins as a health-conscious choice often leads to excess calories and elevated blood sugar levels.

For those who frequently consume beverages, drinks may well be a primary source of your calorie intake – a factor not to be underestimated.

I imagine some readers might now be thinking: what about low-calorie drinks? Surely zero-calorie options are acceptable?

Let me first address low-calorie beverages.

According to the Food Nutrition Labelling Management Specifications, the standard for low-calorie is defined as less than 20 kilocalories per 100 millilitres. This means a 500-millilitre bottle of drink can contain up to 99 kilocalories and still meet the low-calorie criteria.

Consequently, consuming too many low-calorie drinks can easily lead to significant extra calorie intake. Particularly in summer, many people crave refreshment after exercise. Two bottles of low-calorie drinks can add up to around 200 kcal – effectively cancelling out most of the energy expended during exercise.

Now, regarding zero-calorie beverages. Any food or drink containing less than 5 kilocalories per 100 millilitres may be labelled as zero-calorie.

Aspartame possesses a sweetness equivalent to 200 times that of sucrose. While 1 gram of aspartame contains 4 kilocalories, its intense sweetness means only minimal quantities are used in a bottle of cola, rendering its energy content negligible. Acesulfame potassium is neither metabolised nor absorbed by the human body, meaning it passes through unchanged. Consequently, it provides no energy or nutritional value, existing solely to impart sweetness. Sucralose possesses a sweetness equivalent to 600 times that of sucrose and is also scarcely metabolised in the human body, thus it can similarly be considered non-caloric.

Diet Coke employs these three sweeteners as sugar substitutes, achieving a sugar-free yet sweet flavour profile. However, each sweetener imparts sweetness differently, necessitating precise proportional blending to approximate the taste of regular Coca-Cola.

While consuming zero-calorie beverages won't increase body fat, they can desensitise us to the natural flavours of other foods. This dulls our taste buds and makes us less responsive to sweetness on both sensory and psychological levels.

Furthermore, studies suggest artificial sweeteners may stimulate appetite, leading people to consume more food elsewhere and indirectly contributing to weight gain.

Therefore, in the long term, frequent consumption of zero-calorie drinks may prove detrimental to both weight management and overall health.
